Mitsubishi Recalls Nearly 60,000 Vehicles For Faulty Safety System Software

 

Lilburn, Georgia – September 26, 2018 – Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 2018 Mitsubishi Outlander Sport vehicles equipped with a Forward Collision Mitigation (FCM) system, as well as 2018 Mitsubishi Outlander PHEV and Eclipse Cross vehicles and 2017-2018 Outlander vehicles equipped with an Adaptive Cruise Control (ACC) system and/or an Electric Parking Brake (EPB) system.

The Defect

According to the NHTSA Safety Recall Report, the software for the Hydraulic Unit’s Electronic Control Unit (HU-ECU) may be incorrect. Due to this inappropriate software in HU-ECU electrical noise is generated when the pump motor of the H/U operates, which may cause the H/U-ECU to reset.

This defect could prevent the intervention of safety systems when in use, including automatic emergency braking, Anti-lock Braking (ABS), Electronic Stability Control (ESC), or the Brake Auto Hold (BAH) function. If the safety systems do not function as intended, it can increase the risk of a crash. There have been no reported injuries or accidents due to this condition.

Timeline of Events

In March 2017, a field report from Japan was received by MMC. The report stated that the “ACC CHECK” warning appeared in the multi-information display of combination meter while driving. From April 2017 to August 2017, MMC received two additional field reports. In the first case, MMC conducted a bench test with the returned part, but was unable to reproduce the problem. After the second field report, MMC conducted the vehicle test with the additional two returned parts and was able to reproduce the problem with one of the returned parts.

MMC subsequently conducted the bench test again using the driving data of the vehicle test which had formerly successfully reproduced the problem, but was not able to reproduce the problem again, so MMC and the supplier continued to conduct tests from December 2017 to April 2018

Upon conclusion of the company’s investigation, MMC determined that inappropriate software in the H/U-ECU could generate electrical noise when the pump motor operates, causing the H/U-ECU to reset. The flaw in the software was corrected in production, and MMC continued investigating with the purpose of analyzing the variations and estimating future occurrences.

MMC concluded that the failure would occur continuously in the future, and in September 2018 the manufacturer chose to initiate a field action in the US to address the condition and advised Mitsubishi Motors North America, Inc. to conduct a safety recall.

The Solution

Owners of all affected vehicles will be notified and asked to bring their vehicles in to reprogram the H/U-ECU software with countermeasure software. The repair will be performed with no cost to vehicle owners. The new software does not generate the electrical noise which may reset the H/UECU, eliminating the issue. New software for the H/U-ECU was used in production starting with vehicles built in and after April 2018. The NHTSA Campaign Number for this recall is 18V-621

Owners seeking reimbursement for any expenses associated with this recall will be directed in the notification letter to contact the Mitsubishi Customer Relations Department for reimbursement consideration. MMNA will notify owners, and dealers will update the Hydraulic Unit-ECU software, free of charge. The recall is expected to begin October 16, 2018. Owners may contact MMNA customer service at 1-888-648-7820. MMNA’s number for this recall is SR-18-008. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153).

Mitsubishi Recalls More Than 9,000 Vehicles Over Faulty FCM Software

 

Lilburn, Georgia – September 26, 2018 – Mitsubishi Motors North America (MMNA) is recalling certain 2018 Mitsubishi Outlander PHEV, Outlander Sport, 2018-2019 Eclipse Cross, and 2017-2018 Outlander vehicles equipped with a Forward Collision Mitigation (FCM) system that detects pedestrians. Only vehicles that were equipped with Forward Collision Mitigation (FCM) system are affected, with the total number of vehicles being recalled totaling 9,166.

The Defect

According to the NHTSA Safety Recall Report, due to incorrect software, the FCM-ECU (Electronic Control Unit) may apply braking for longer than needed. The error may occur when a pedestrian was registered as being in front of the vehicle, even after a pedestrian is no longer detected. If the FCM-ECU software activates the brake for longer than necessary, the driver may react by applying additional braking. The resulting rapid deceleration of the vehicle has been suspected to increase the risk of a rear-end collision or cause the driver to lose control of the vehicle.

Timeline of Events

During March through May 2017, MMC received three field reports from the Czech Republic and Japan indicating that the vehicle brake was activated by FCM system. The reports stating the brake activation occurred when there were no pedestrians or other vehicles in front of the vehicle. MMC began an investigation. Between May and October 2017, as a result of the investigation, it was concluded that the FCM system operated properly. However, in February 2018, MMC received an accident report from Australia which stated that rear-end collision had occurred due to the vehicle brake being activated by the FCM system. Again, MMC concluded the FCM system operated properly.

In May 2018, two additional accident reports from Singapore and Japan were received, and it was confirmed that the driver of each vehicle had depressed the brake pedal strongly when the brake was activated by the FCM system. This caused the vehicles to be decelerated rapidly. In June 2018, MMC completely reprogrammed the software of the FCM-ECU in production, in order to specifically shorten the operation time of the brake by the FCM system. This safeguard is designed to help prevent the driver from choosing to apply a stronger brake when the danger is already past or when not necessary.

MMC subsequently continued its investigation to assess the safety risk of affected vehicles, and in September 2018, MMC determined that a field action was necessary in the US to address the potential risk, although there had been no adverse reports from the US. MMC advised Mitsubishi Motors North America, Inc. to conduct a safety recall.

The Solution

Owners of all affected vehicles will be notified and encouraged to bring their vehicles in to reprogram the FCM-ECU software with countermeasure software. The repair will be performed at no charge to vehicle owners. The recall is expected to begin October 16, 2018.

Any owners seeking reimbursement for any expenses associated with this recall will be directed in the notification letter to contact the Mitsubishi Customer Relations Department for reimbursement consideration.

Owners may contact MMNA customer service at 1-888-648-7820. MMNA’s number for this recall is SR-18-007. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153).

Mitsubishi recalls vehicles with defective Takata air bags

Cypress, Calif. – April 30, 2018 – Mitsubishi Motors North America has recalled more than 17,000 vehicles potentially equipped with defective Takata air bag assemblies, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2004-2006 Mitsubishi Lancer sedans produced between Aug. 3, 2003, and Aug. 31, 2006.
The Japanese automaker suspects all of the vehicles referenced in the action contain the defective components.
This particular recall involving Takata air bags is part of a larger safety campaign stretching back to 2014 and involving more than 37 million vehicles from 13 automakers, according to the NHTSA.
The Defect
Affected vehicles contain Takata air bag assemblies featuring defective inflators that are prone to combustion upon deployment. When exploded, the metal inflator housing fragments, sending bits of sharp throughout the cabin. Consequently, these fixtures pose a serious safety hazard to occupants. Takata air bags have killed 20 people and injured hundreds more worldwide, the Los Angeles Times reported.
Timeline of Events
Takata on May 18, 2015, submitted a Defect Information Report which advised all automakers involved with vehicles containing its air bag assemblies to expand ongoing recalls. The NHTSA relayed this information to automotive companies May 27, 2015. In response, Mitsubishi expanded an ongoing recall involving 2004-2005 Lancer sedans to include all remaining 2005 Lancer vehicles, as well as those produced in 2006 using the Takata air bag inflators.
Between May 2015 and September 2017, the automaker replaced defective air bag assemblies with temporary like-for-like replacements. During this time, Mitsubishi also developed a viable permanent replacement, which passed the final testing phase in September 2017.
Over the following months, the automaker mass-produced the parts to build of up sufficient supply for an expanded recall action addressing all of the vehicles that received temporary replacements. On March 29, 2018, Mitsubishi reviewed the matter and decided to launch a voluntary safety recall.
The Solution
The automaker will direct dealers to replace the Takata air bag assemblies in affected vehicles free of charge, according to an NHTSA recall acknowledgement document. Mitsubishi intends to notify dealers April 19, 2018, and reach out to owners via first-class mail April 26, 2018.

Mitsubishi recalls vehicles with defective windshield wipers

Cypress, Calif. – Feb. 28, 2018 – Mitsubishi Motors North America has recalled more than 158,000 vehicles potentially equipped with defective windshield wipers, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects multiple models, including:

  • 2011-2012 Mitsubishi Outlander Sport sport utility vehicles produced between Aug. 26, 2010, and June 1, 2012.
  • 2013-2015 Mitsubishi Outlander Sport SUVs produced between July 20, 2012, and Nov. 25, 2015.
  • 2016 Mitsubishi Outlander Sport SUVs produced between Jan. 11, 2016, and July 8, 2016.

Mitsubishi suspects all of the vehicles referenced in the recall contain the defective components.

The Defect

The models named in this recall feature front windshield wiper ball joint assemblies that are prone to corrosion. Specifically, the resin case protecting the ball joint oxidizes after coming into contact with moisture and degrades at an accelerated rate, leading the ball joint to separate from the wiper link and completely impair wiper functionality. This poses a serious safety hazard to drivers, as they may not be able to clear their windshields when navigating inclement weather. However, Mitsubishi has not received field reports connecting any accidents or injuries connected to the defective parts.

Timeline of Events

The Japanese automaker received a report in March 2010 detailing an instance in which a driver operating an Outlander with limited windshield wiper functionality, according to an NHTSA chronology document. Mitsubishi launched an investigation and found that the windshield wiper ball joint on the vehicle had corroded but was unable to pinpoint the root cause of the oxidization. Between March 2010 and September 2015, the automotive company monitored the field for similar incidents. Over this time, the company received 10 reports mentioning corroded wiper ball joints.

In February 2015, Mitsubishi received another field report referencing the problem, which had caused the complete loss of windshield wiper functionality. Engineers conducted additional environmental tests in an effort to replicate the problem but could not do so. This led them to assume that the corrosion was a result of high-pressure washing. Mitsubishi continued the limited monitoring program through September 2016. During this time, the company conducted laboratory tests that revealed the front deck garnishes on the Outlander Sport may degrade over time, leading to moisture penetration in the vicinity of the windshield wiper ball joint. This finding led Mitsubishi to conduct a voluntary recall in October 2016 that applied to stock Outlander models and excluded the Sport variation.

In November 2017, the automaker began field monitoring for the Outlander Sport. Mitsubishi received some reports related to the Outlander Sport over this time but the claim rate failed to surpass that of the stock model. Nevertheless, the automotive company decided to conduct a voluntary recall Feb. 2, 2018, to reduce the likelihood of harm to drivers. Dealers received official notification Feb. 23, 2018.

The Solution

Mitsubishi has directed dealers to replace the windshield wiper rods and motor crank arms in affected vehicles free of charge, according to an NHTSA recall acknowledgment document. The automaker will notify owners via first-class mail April 10, 2018. Those in need of more immediate assistance can connect with Mitsubishi customer service personnel at (888) 648-7820. Callers should use the internal recall reference code SR-18-004. Owners can also reach out to the NHTSA directly using its Vehicle Safety Hotline at (888) 327-4236.

Mitsubishi recalls vehicles with defective brakes

 

Cypress, Calif. – Feb. 14, 2018 – Mitsubishi Motors North America has recalled more than 170,000 vehicles possibly equipped with corrosion-prone and improperly installed brake components, according to documentation submitted to the National Highway Transportation Safety Administration.

The safety campaign affects 2014-2016 Mitsubishi Outlander sport utility vehicles produced between April 12, 2013, and Feb. 2, 2016, as well as 2013-2016 Mitsubishi Outlander Sport SUVs manufactured between July 20, 2012, and July 8, 2016. The Japanese automaker suspects all of the models referenced in the action contain the defective components.

The Defect

Affected vehicles could contain parking brake shafts and rear brake caliber boots that are not properly water-sealed. As a result, moisture could penetrate both of these fixtures and cause extensive corrosion damage. Additionally, these models feature defective automatic brake pad adjusters. Together, these parts greatly inhibit braking functionality and therefore pose a serious threat to occupants. However, Mitsubishi has not received reports connecting the defective components to any accidents or injuries.

Timeline of Events

In October 2014, Mitsubishi received a field report from a dealer in the U.K. outlining an instance of rear brake disintegration. The automaker launched an investigation and in October 2014 came to the conclusion that corrosion had caused the parking brake shaft to stick. Engineers took this data and began developing a production solution, which debuted in January 2016. At this point, assembly crews began coating all parking brake components in an anticorrosion covering. Mitsubishi launched an extended field monitoring program to measure the effectiveness of the coated components.

As this situation unfolded, Mitsubishi dealt with another developing safety issue centered on brake assemblies. In February 2015, the company received a field report from the Japanese market that referenced nonworking automatic brake pad adjusters. Mitsubishi engineers investigated the issue for more than one year but could not pinpoint a root cause. They did, however, find that one of the washers installed on one of the problematic brake calibers was scratched. Investigators began working with operations to develop a technical solution that would prevent scratching while also moving forward with their root cause analysis.

In October 2016, Mitsubishi introduced new washers made of stronger material that were impervious to scratching. The investigation moved forward.

Nearly one year later in September 2017, compliance officials at the company discovered that its brake caliber supplier, Akebono Brake Industry, had performed ineffective post-production inspections. This resulted in the release of defective calibers that did not meet predetermined production specifications. These unfit features, combined with the scratched washers, affected the performance of brake the pad automatic adjusters, which in turn led to decreases in braking performance due to increased pad wear.

On Jan. 19, 2018, quality assurance personnel met and decided that a voluntary safety recall aimed at addressing both braking issues was necessary.

The Solution

Mitsubishi intends to direct dealers to inspect and, if necessary, replace the rear brake calibers and parking brake boots on affected vehicles free of charge, according to an NHTSA recall acknowledgment document. The car company plans to notify dealers Feb. 9 and reach out to owners via first-class mail March 27.

Owners in need of more immediate assistance can connect with Mitsubishi customer service staff at (888) 648-7820. Callers should use the internal recall reference code SR-18-002. Owners can also speak with the NHTSA using its Vehicle Safety Hotline at (888) 327-4236.

Mitsubishi recalls vehicles with defective drive belt components

 

Cypress, Calif. – Feb. 13, 2018 – Mitsubishi Motors North America has recalled more than 141,000 vehicles potentially equipped with defective drive belt components, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects multiple models, including:

  • 2009-2012 Mitsubishi Lancer sedans produced between March 20, 2008, and Nov. 17, 2011.
  • 2010-2012 Mitsubishi Lancer Sportback sedans produced between June 17, 2009, and Nov. 15, 2011.
  • 2008-2012 Mitsubishi Outlander sport utility vehicles produced between June 25, 2008, and Nov. 16, 2011.
  • 2011-2012 Mitsubishi Outlander Sport SUVs produced between Aug. 26, 2010, and Dec. 15, 2011.

The Japanese automaker suspects all the vehicles referenced in the recall contain the defective features.

The Defect

The models included in the safety action could contain drive belt automatic tensioners whose flanges are prone to cracking. Such an event could lead to complete drive belt detachment, resulting in the immediate termination of engine and power steering operations, and increasing the likelihood of an accident. As a result, the defective part poses a serious threat to occupants. However, Mitsubishi has not received reports connecting the any accidents or injuries to the defect.

Drivers with vehicles on the verge of shutting down due to drive belt automatic tensioner fracturing will see the battery charge warning light illuminate.

Timeline of Events

Mitsubishi received a field report in September 2010 describing an instance of automatic tensioner breakage. This prompted the company to launch an investigation into the issue to ascertain a root cause. In December 2011, engineers for the automaker found that production staff had swapped the bearing in the automatic tensioner for a lead-free alternative in March 2008 and suspected that the new product was cracking when operating in high-load environments. Mitsubishi reshaped the bearing to reduce surface stress and initiated a field monitoring campaign with an expiration date of November 2015.

In December 2015, the car manufacturer reviewed the results of the four-year field monitoring program and began another program scheduled to conclude in January 2018.

Last month, Mitsubishi conducted another data review and found the occurrence of automatic tensioner breakage was higher than expected and increasing. The company called for a voluntary safety recall Jan. 19 to address the problem.

The Solution

Mitsubishi intends to direct dealers to replace the drive belt tensioners in affected vehicles free of charge, according to an NHTSA recall acknowledgment document. The automaker will notify dealers Feb. 9 and reach out to owners via first-class mail March 27. Those in need of more immediate assistance can contact Mitsubishi customer service at (888) 648-7820.

Mitsubishi recalls vehicles defective sunroof framing

 

Cypress, Calif. – Feb. 8, 2018 – Mitsubishi Motors North America has recalled more than 56,600 vehicles potentially equipped with defective sunroof framing components, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects multiple models, including:

  • 2008-2010 Mitsubishi Lancer sedans produced between Jan. 15, 2007, and March 3, 2010.
  • 2009-2010 Mitsubishi Lancer Evolution sport sedans produced between Sept. 1, 2008, and Oct. 30, 2009.
  • 2010 Mitsubishi Lancer Sportback sedans produced between June 17, 2009, and Oct. 30, 2009.
  • 2007-2010 Mitsubishi Outlander sport utility vehicles produced between Sept. 8, 2006, and Nov. 3, 2009.

The automaker suspects all vehicles referenced in the action contain the defective components.

The Defect

Affected models feature improperly manufactured polyurethane sunroof frames that may degrade in humid or high temperature environments and lead to complete detachment of the sunroof glass. This poses a serious safety risk to occupants, as the falling glass could not only cause injury but also increase the likelihood of an accident. That said, Mitsubishi has not received reports connecting the defect to accidents or injuries of any kind.

Timeline of Events

Mitsubishi received a field report from the Japanese market in March 2015 detailing an instance in which the sunroof glass installed in a vehicle detached from the sunroof frame. This prompted the company to launch an investigation in collaboration with its sunroof assembly supplier, the Webasto Japan Company. Between April 2015 and December 2017, the two parties carried out detailed field investigations and performed internal tests in an effort to duplicate the outcome described in the original report.

In December 2017, Mitsubishi engineers confirmed that Webasto had changed the polyurethane material it used in its sunroof frames in 2009, switching to a more aesthetically appealing alternative that also seemed to exhibit better bonding. The report received in the March 2015 seemed to contradict this assessment and Mitsubishi deemed the material defective, postulating that it lost bonding power in hot, humid weather.

On Jan. 19, the automaker initiated a voluntary safety recall to address the problem.

The Solution

Mitsubishi intends to direct dealers to replace the sunroof assemblies in affected models free of charge, according to an NHTSA recall acknowledgment document. The company plans to notify dealers Feb. 9 and reach out to owners via first-class mail March 27.

Those in need of more immediate assistance can connect with Mitsubishi customer service personnel at (888) 648-7820. Callers should use the internal recall reference code SR-18-003. Owners can also reach out the NHTSA directly using the agency’s toll-free Vehicle Safety Hotline at (888) 327-4236.
