Toyota Recalls Nearly 1300 4Runners for Insufficient Cargo Load Capacity

Laguna Hills, CA – November 2, 2018 – Southeast Toyota Distributors, LLC (SET) is recalling certain 2017-2019 Toyota 4Runner vehicles that SET modified to be equipped with a TRD wheel package on which a certification label was incorrect. This recall is expected to affect 1295 vehicles in North America.

The Defect

According to the NHTSA Recall Safety Report, the Gross Vehicle Weight Rating (GVWR) on the certification label may be incorrect, possibly resulting in the vehicle being overloaded. An overloaded vehicle can increase the risk of a crash.

Timeline of Events

During a routine data validation audit on in late September 2018, it was discovered that the accessory weight for the TRD Wheel Package was not accurately relayed to the software used to calculate the load carrying capacity modification labels. The TRD Wheel Package is installed by SET at the request of Toyota and is considered standard equipment on the special edition TRD 4Runner from Toyota. However, the TRD Wheel package weight was not included in the final vehicle certification, and should have been included in the load carrying capacity modification label calculation. This led to affected vehicles having the incorrect cargo weight capacity listed and some having a negative cargo carrying capacity.

The Solution

SET will notify the customers by mail of the noncompliance. An accurate label will be provided to apply over the inaccurate label at no charge. Each label will be customized for the corresponding customer’s vehicle based on the net weight of the accessories installed. Fifteen (15) vehicles have been identified which cannot be remedied solely with a revised label. They may require an alternate remedy to remain in line with net weight restrictions and allow cargo carrying capacity to shift out of negative. These customers will be contacted separately, and options provided, one of which may be the  exchange or upgrade of accessories at no charge to reduce the overall weight and increase cargo carrying load capacity.

Customers will be notified and arrangements made to provide a suitable remedy. SET expects the mailing of customer notification letters to begin on or about December 24, 2018. Owners may contact SET customer service at 1-866-405-4226. SET’s number for this recall is SET18A. Owners may also call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). The NHTSA Campaign Number for this recall is 18V-753.

Toyota Recalls Certain 2019 C-HR Vehicles Due to Improperly Tightened Axle Bearing Bolts

Laguna Hills, CA – October 19, 2018 – Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2019 Toyota C-HR vehicles due to insufficiently tightened rear axle bearing bolts. The recall is expected to include 681 potentially affected vehicles, as no more than 0.1% of those included are expected to actually contain the defect. Toyota estimates this based on the results of inspections that, as of September 25th, out of 4500 inspected vehicles, there were 4 vehicles with the hub bearing bolts not tightened sufficiently.

The Defect

According to the NHTSA Recall Safety Report, the subject vehicles are equipped with left-hand and right-hand rear axle hub bearing assemblies. These are connected to the rear axle carrier subassemblies by four rear axle bearing bolts. One or more rear axle bearing bolts on a few vehicles may not have been sufficiently during the manufacturing process at one particular facility.

Any insufficiently tightened bolt could become loose during vehicle operation and could eventually detach. Any detached bolt could damage the rear brake components during rotation, or result in a rear wheel detaching completely, Either of these events can cause a reduction of brake performance or a potential loss of vehicle stability, increasing the risk of a crash.

Timeline of Events

In late August 2018, Toyota received a field report from the Russia market about a 2018MY C-HR. The report indicated that of the four rear left-hand axle hub and bearing bolts, three were loose and one was missing altogether.  Toyota Motor Manufacturing Turkey (TMMT) investigated the possibility of any abnormality in the hub and bearing assembly manufacturing process.

A review revealed that during the production period spanning four days after a planned manufacturing facility shutdown in mid-June, tightening errors occurred sporadically in the hub bearing tightening process. This was confirmed to be due to several process and equipment changes in the hub and bearing assembly manufacturing process which caused a failure to confirm the torque and allowed the passing of parts to the next process.

TMMT initiated a 100% tightening torque confirmation and introduced a series of improvements to prevent bolt tightening error and began to inspect the vehicles in Toyota inventory equipped with the hub and bearing assemblies that were produced in the indicated production period.

An additional field report was received on September 18th from the UK market describing a C-HR vehicle produced outside the time period, with two loose and two missing rear left-hand axle bearing bolts. The investigation allowed an expanded time period for potential issues to be identified and confirmed, and Toyota decided to conduct a voluntary safety recall campaign in early October.

The Solution

All known owners of the subject vehicles will be notified by first class mail to return their vehicles to a Toyota dealer. The dealership will inspect all rear axle hub bearing bolts, and if a bolt is found to be loose or detached, the dealer will replace the rear axle hub bearing assembly and rear axle carrier sub-assembly with new parts, free of charge. The recall is expected to begin November 9, 2018. Owners may contact Toyota customer service at 1-888-270-9371. Toyota’s number for this recall is J0Y.

Owners may also call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). The NHTSA Campaign Number for this recall is 18V-710.

Toyota Recalls More Than 168,000 Vehicles for Potential Airbag Malfunction

Laguna Hills, CA – October 16, 2018 – Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018-2019 Toyota Tundra and Sequoia vehicles and 2019 Toyota Avalon and Avalon Hybrid vehicles. The air bag electronic control unit (ECU) may erroneously detect a fault during the vehicle start-up self-check. If this occurs, the ECU may not deploy the airbags as intended, in the event of a crash. The defect affects in excess of a potential 168,000 vehicles.

The Defect

According to the NHTSA Recall Safety Report, due to inappropriate programming in the subject vehicles, the Airbag (SRS) ECU may erroneously detect a fault in one or more of the front or side SRS satellite sensors during a self-check that occurs at each vehicle start up. This condition will cause the vehicle to set a specific trouble code, disable the affected sensor(s), sound a warning buzzer, activate multiple warning lights, and display a message on the combination meter display. If a fault is erroneously detected, the Airbag ECU may not appropriately identify the crash condition if a crash occurs, and the airbags may not deploy as intended, significantly increasing the chance of injury.

Toyota is unable to provide an estimate of the percentage of the vehicles to actually contain the noncompliance. Whether the condition will occur prior to first sale and constitute a noncompliance will differ depending on part variation and whether normal sensor variances will cause the inappropriate programming of the diagnostic function to set a specific trouble code in each case.

Timeline of Events

In early July 2018, Toyota received reports describing illumination of the SRS warning light, which was the result of one of a specific type of diagnostic trouble code (DTC) being set. The light was accompanied by a warning buzzer, master warning light illumination, and a message on the multi-information display. Toyota recovered replaced SRS satellite sensors and began an investigation.

In mid-July 2018, the supplier performed bench testing of the sensors alone, and did not identify a fault. Testing was then conducted with the sensors connected to the entire SRS system including the ECU and, in some cases, the same DTCs related to the airbag sensors were recreated.

In early August, a review of the Airbag ECU software identified that the parameters for this self-check were not correct for the type of satellite sensors used in the system, which could result in a failure of the self-check. Failure of the self-check could disable only the sensor which failed for that key cycle. Each ignition on cycle performs the self-check, and factors such as heat can affect whether the sensor will pass this check using the incorrect parameters.

A study was initiated to evaluate how the SRS system would function in the event of a crash with any of these satellite sensors disabled. Based on the results of the investigation, the results of the aforementioned analysis, and the field information from the U.S. market indicating that this phenomenon could occur prior to first sale, on September 28, 2018, Toyota decided that the subject vehicles may not meet certain requirements and issued a voluntary recall to correct the problem.

The Solution

All known owners of the subject vehicles will be notified by first class mail to return their vehicles to a Toyota dealer. The dealers will update the software of the Airbag ECU at no cost to owners. As the owner notification letters will be mailed out well within the active period of the Toyota New Vehicle Limited Warranty, all involved vehicle owners for this recall would have been provided a repair at no cost under Toyota’s Warranty. The recall is expected to begin October 22, 2018.

Owners may contact Toyota customer service at 1-888-270-9371. Toyota’s number for this recall is J0X. Owners may also call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). The NHTSA Campaign Number for this recall is 18V-685.

Toyota Recalls More Than 80,000 Prius Hybrids for Vehicle Stall Problems

Laguna Hills, CA – October 15, 2018 – Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles due to excessive voltage in the inverter which may cause the hybrid system to shut down and the vehicle to stall while being driven. This recall affected more than 80,000 vehicles, including ones subject to prior recalls.

The Defect

According to the NHTSA Recall Safety Report, the vehicles subject to this recall contain software used to control the Intelligent Power Module (IPM) within the inverter assembly. This module is part of the vehicle’s hybrid system. Certain characteristics of the software used to control the boost converter in the IPM could cause higher thermal stress than normal to occur in specific transistors in the IPM, specifically during high-load driving activities, such as accelerating during highway driving. Over time, stress could damage certain transistors.

In limited instances, the motor/generator ECU could reset, or – if a specific transistor within the IPM fails in a certain way during a high-load driving condition – an abnormally high voltage could be generated. In either case, there is the possibility that the hybrid system could shut down instead of entering a failsafe driving mode, which could cause the vehicle to lose motive power while driving at higher speeds, increasing the risk of a crash. Drivers may be warned of transistor damage via the illumination of various warning lights and the display of a warning message on the instrument panel.

Timeline of Events

Between the month of January and March 2018, based on VOQs and other available information, NHTSA contacted Toyota about allegations of potential incidents where vehicles experienced a loss of motive power while driving at some time after having received the software updates from prior, related recalls (14V-053 and 15V-449.) Toyota began reviewing the information and recovering parts from the field.

Toyota conducted a search of available data for vehicles involved in 14V-053 and 15V-449 and identified a limited number of instances where the data in connection with certain inverter-related trouble codes suggested a possible “ready off.” Based on an initial analysis of recovered failed parts, damage was observed in certain transistors. Toyota surveyed vehicles to identify the software version present in field vehicles, and, in those cases where an inverter failure occurred. Continued analysis of the recovered failed inverters and freeze frame data in a limited number of cases did identify an unexpected, abnormally high voltage value related to the hybrid boost converter.

In September 2018, a design review of the software used to control the hybrid system components in addition to a review of the inverter circuit design identified a potential mechanism for the hybrid system to shutdown instead of entering a failsafe mode based on the observation of an abnormally high voltage in extremely rare cases. Toyota could not exclude the possibility that a limited population of vehicles did not successfully receive a software update in one or both of the ECUs, and the company decided to conduct a voluntary safety recall campaign.

The Solution

According to the Toyota Defect Information Report, Toyota will notify owners, and dealers will update the software for the motor/generator control electronic control unit (ECU) and the hybrid control ECU as necessary, free of charge. Interim notices informing owners of the safety risk began October 22, 2018. Owners will receive a second notice when the remedy becomes available.

Owners may contact Toyota customer service at 1-888-270-9371. Toyota’s number for this recall is J0V. Owners may also call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). The NHTSA Campaign Number for this recall is 18V-684. The software updates in this recall are needed even if the vehicle had the software previously updated under recalls 14V-053 or 15V-449.

Toyota Recalls Multiple 2018-2019 Vehicles Due to Air Bag Deployment Issue

Laguna Hills, CA – October 12, 2018 – Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018-2019 Toyota Tundra and Sequoia vehicles and 2019 Toyota Avalon and Avalon Hybrid vehicles due to a programming error that could affect air bag deployment.

The Defect

According to the NHTSA Safety Recall Report, Toyota has determined that due to inappropriate programming of the air bag electronic control unit (ECU), a fault may be erroneously detected and disable a front or side supplemental restraint system (SRS) sensor.

If this were to occur, the air bag ECU may not appropriately identify a crash condition, the air bags may not deploy as intended, and as a result, this could lead to an increased risk of injury in the event of a crash.

Timeline of Events

Toyota received reports describing illumination of the SRS warning light accompanied by a warning buzzer, master warning light illumination, and a message on the multi-information display, and began an investigation in June 2018.

A review of the Airbag ECU software identified that parameters for a routine self-check were not correct for the type of satellite sensors used in this system. This can result in a failure of the self-check, which will disable only the sensor which failed for that key cycle. Factors such as heat can affect whether the sensor will pass this check using the incorrect parameters.

Based on the results of the investigation, Toyota decided that the subject vehicles may not meet certain mandated requirements and issued a recall.

The Solution

All known owners of the subject vehicles will be notified by first class mail to return their vehicles to a Toyota dealer. The dealers will update the software of the Airbag ECU at no cost to owners. As the owner notification letters will be mailed out well within the active period of the Toyota New Vehicle Limited Warranty, all involved vehicles are assumed to be covered for this repair under Toyota’s Warranty.

The recall is expected to begin October 22, 2018. Owners may contact Toyota customer service at 1-888-270-9371. Toyota’s number for this recall is J0X. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). The NHTSA number for this recall is 18V-685.

Toyota Recalls 1 Million Toyota Prius Models Due to Fire Risk

 

Lilburn, Georgia – Sept. 15, 2018 – Toyota is recalling 192,000 of its 2016 to 2018 Prius hybrids that were sold in the U.S. due to a fire risk. According to a company press release, wiring in the front of the vehicle may wear over time, potentially resulting in a short circuit, which could cause a fire.

Affected vehicles include certain 2016 to 2018 Toyota Prius cars manufactured between June 2015 and May 2018. These vehicles are part of a larger 1 million vehicle worldwide recall, with the majority of the remaining vehicles sold in Japan, as well as some located in Canada, the U.K., Europe and Australia.

The Defect

These vehicles have an engine wire harness consisting of a bundle of wires wrapped in a protective sleeve. The wire harness is connected to the hybrid vehicle Power Control Unit, which controls electricity within the hybrid drivetrain. A portion of the wire harness can potentially contact the cover at this connection and wear over time. The resulting friction can cause an electrical short circuit, which can generate heat, leading to a vehicle fire.

Timeline of Events

As noted by Consumer Reports in early September, the National Highway Traffic Safety Administration (NHTSA) has stated that Toyota discovered the defect after a dealer in Japan reported “abnormal odor, smoke, and flames” from a customer’s vehicle. To date, Toyota says that a single warranty claim in the U.S. may be related to the issue, but this has not been confirmed.

The recall covers all Toyota Prius and Prius Plug-in models built between June 2015 and May 2018, and also affects Toyota C-HR plug-in hybrid models sold in Europe, Japan, and Australia, but not in the U.S. Former Toyota recalls for Prius models over the past few years have included brake issues and software failures.

The Solution

According to Toyota, all repairs will be provided at no cost to customers. All known owners will receive a notification by first class mail starting in late October.

For all involved vehicles, Toyota dealers have been instructed to check the engine wire harness assembly to see if a wire core is exposed. If there is visible exposure, the engine wire harness assembly will be replaced with a new one that includes a stronger protective sleeve. If a wire core is not currently exposed, specialized protective tape will be installed on the engine wire harness assembly to prevent wear at the point of contact.

Owners may contact Toyota customer service at 1-800-331-4331. Customers can also access current information on open safety recalls by Toyota by entering their Vehicle Identification Number (VIN) at: www.toyota.com/recall. or nhtsa.gov/recalls.

Toyota recalls vehicles with defective engine parts

 

Plano, Texas – June 29, 2018 – Toyota Motor North America has recalled more than 115,000 vehicles potentially equipped with defective engine parts, according to a company press release. The campaign affects multiple vehicles across the Lexus brand, including:

  • 2007-2011 Lexus GS 350 sedans.
  • 2006-2013 Lexus IS 350 sedans.
  • 2010-2014 Lexus IS 350C sedans.
  • 2007-2011 Lexus GS 450H sedans.

The Defect

Affected models contain six-valve engines with fuel pulsation dampers whose diaphragms were constructed with faulty material and are therefore prone to cracking. Should diaphragm deterioration occur, a fuel leak may materialize, increasing the likelihood of engine fire. As a result, this defect poses a serious safety hazard to occupants. However, the Japanese automaker has yet to receive field reports that connect the defective engine components to any accidents or injuries.

Timeline of Events

Toyota has yet to release information about the internal investigation that uncovered the defect.

The Solution

The car manufacturer has directed dealers to replace engine fuel delivery pipes in affected vehicles free of charge. The company intends to notify owners via first-class mail sometime in August 2018. Owners in need of assistance prior to the start of the recall can speak with Toyota customer service representatives by calling (800) 331-4331. They can also connect with the National Highway Transportation Safety Administration through the agency’s toll-free Vehicle Safety Hotline at (888) 327-4236.

Toyota recalls vehicles with defective brake components

Plano, Texas – April 19, 2018 – Toyota Motor Engineering and Manufacturing has recalled more than 6,000 vehicles potentially equipped with defective brake components, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects models across multiple brands, including:
  • 2017 Lexus RX350 sport utility vehicles produced between Oct. 2, 2017, and Oct. 18, 2017.
  • 2018 Toyota Camry sedans produced between Oct. 5, 2017, and Nov. 3, 2017.
  • 2018 Toyota Highlander sport utility vehicles produced between Oct. 4, 2017, and Nov. 3, 2017.
  • 2018 Toyota Sienna minivans produced between Oct. 6, 2017, and Oct. 23, 2017.
  • 2017 Toyota Tacoma pickup trucks produced between Oct. 5, 2017, and Nov. 3, 2017.
The Japanese automaker is unsure how many of the recalled vehicles actually contain the defective components.
The Defect
Affected vehicles could come with problematic vacuum pump assemblies. These fixtures are designed to siphon oil from the engine to power brake boosters which, in turn, support optimal braking assist functionality. However, the pumps installed in the recalled models contain improperly machined rotor oil galleys, impairing their ability to extract oil from the engine and power brake boosters.
In some instances, the rotor galleys may cause other internal parts within the vacuum pumps to break, resulting in the failure of the entire rotor, the brake booster and the brake assist system. Such an event would increase the likelihood of an accident. However, Toyota has yet to receive field reports connecting the defective vacuum pump assemblies to any accidents or injuries.
Timeline of Events
On Oct. 11, 2017, an engineer conducting a post-production test drive at the Toyota manufacturing plant in San Antonio, Texas encountered a vehicle with an overly firm brake pedal, according to an internal document submitted to the NHTSA. Toyota inspected the vehicle and found that the vacuum pump was not effectively powering the brake booster, resulting in pedal resistance. Additional analysis revealed that the rotor oil galley within the pump did not contain properly drilled holes, prompting the automaker to contact Magna Powertrain of Mexico, the vendor that provided the vacuum pump assembly, and initiate a joint investigation.
As this inquiry moved forward, engineers at another Toyota assembly site pinpointed other vehicles with the same braking problem, which engineering teams quickly attributed to defective vacuum pumps. Soon after these additional defective vehicles were identified, the car manufacturer discovered that the Magna production facility on Aug. 7, 2017, had suffered an unexpected power surge, resulting in significant downtime. During a shop floor reset, maintenance teams failed to properly recalibrate the drilling machine.
Consequently, Magna produced a large number of vacuum pump assemblies with improperly drilled rotor oil galley holes. Over the course of its investigation, Toyota also found that Magna’s documented maintenance policies did not direct teams to perform recalibrations following shutdowns, meaning operations most likely resumed without further process analysis. Magna ultimately made the proper calibrations during Aug. 9, 2017, but by that point, a significant number of pieces had come off the line and been shipped to customers. The company amended its maintenance procedures to address this error.
In January 2018, Toyota began testing the defective vacuum pumps in-house to determine their impact on vehicle driveability. Within a month, engineers had determined that the components could not effectively extract oil from the engine via the improperly drilled rotor oil galley holes. They also found that this, in turn, may damage the vacuum pump assembly and eventually result in the complete loss of the braking assist feature.
On March 28, 2018, Toyota safety and quality assurance officials reviewed the results of the investigation and determined that a voluntary safety recall was necessary. The automaker notified dealers April 3, 2018.
The Solution
Toyota has directed dealers to replace the vacuum pump assemblies in affected vehicles free of charge, according to an NHTSA recall acknowledgement document. The company intends to notify owners via first-class mail between May 31, 2018, and June 2, 2018. However, owners in need of assistance prior to the start of the recall can reach out to Toyota customer service at (800) 255-3987. Callers should use the internal campaign reference code J0K/JLD. Owners can also contact the NHTSA directly using the agency’s Vehicle Safety Hotline at (888) 327-4236.
