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.

Toyota recalls sedans with defective fuel lines

 

Plano, Texas – March 7, 2018 – Toyota Motor Engineering and Manufacturing has recalled almost 12,000 vehicles potentially equipped with defective fuel lines, according to documentation submitted to the National Highway Transportation Safety Administration. The action affects 2018 Toyota Camry sedans produced between June 22, 2017, and Nov. 29, 2017. The automaker is unsure what percentage of the recalled vehicles contain the defective parts.

The Defect

The models involved in the campaign contain V-6 engines, which feature two fuel delivery lines connected to two fuel hoses. The fuel delivery lines were not properly connected to the hoses during assembly, increasing the likelihood of fuel leakage and engine fires. This defect obviously poses a serious threat to occupants. However, Toyota has not received reports connecting the defective fuel lines to any accidents or injuries.

Timeline of Events

Toyota in November 2017 received a field report from the U.S. market outlining an instance in which sales staff cleaning a new 2018 Camry pre-delivery noticed a fuel odor coming from the engine compartment, according to chronology document the automaker submitted to the NHTSA. Engineers inspected the vehicle and found that fuel lines had detached from the fuel hoses, leaking gasoline into the engine compartment. The automaker launched an investigation immediately.

Quality assurance staff first reviewed the established fuel line assembly standards, which direct line workers to ensure the fuel lines and hoses are properly connected. After looking over these procedures and comparing them to the actions taken by assembly personnel at the plant from which the vehicle originated, Toyota decided that defect was not the result of flawed processes or execution.

Toyota then reached out to the vendor that supplied the parts and collaborated with the organization to review its internal production processes. This evaluation failed to yield a root cause. Soon after, the car manufacturer analyzed additional 2018 Camry sedans and found that a significant number exhibited the same defective fuel line assemblies.

However, Toyota did not discover an underlying reason for the detachment issue but put new assembly measures into place to more effective ensure engagement between fuel lines and hoses. The organization implemented additional sensor checks on its lines and updated its standard working procedures to place more emphasis on fuel line assembly functionality. It also launched two field studies to collect additional data on the phenomenon.

On Feb. 6, 2018, Toyota quality assurance and safety personnel reviewed the matter and decided to conduct a voluntary safety recall. The automaker notified dealers Feb. 14, 2018.

The Solution

Toyota has directed dealers to inspect the fuel line assemblies in affected vehicles and correct them if necessary, according to an NHTSA recall acknowledgement document. These repairs will be done at no charge to the customer. Toyota intends to reach out to owners March 30, 2018, via first-class mail. Those in need of assistance prior to the start of the recall can contact Toyota customer service staff at (888) 270-9371. The internal recall identification code for the recall is J0G. Owners can also contact the NHTSA using its Vehicle Safety Hotline at (888) 327-4236.
