General Motors will be contacting the owners of certain Chevrolet Bolt EVs and EUVs for two separate problems. A small number of 2022 Chevy Bolt EVs and EUVs may have been manufactured with improperly tightened or missing airbag fasteners and approximately 50,413 2017-2019 Chevy Bolt EVs are at risk of a battery fire.
2022 Chevy Bolt EVs and EUVs Airbags Improperly Installed: In June 2021, a GM quality manager submitted a report to GM’s Speak Up For Safety program following reports of vehicles missing steering wheel airbag fasteners that caused the airbag cover to be poorly seated. GM determined that these vehicles were taken off-line during manufacturing and the technician did not fully complete installation of the steering wheel airbag. The issue was reviewed by GM’s Open Investigation Review and GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall.
Dealers will inspect the driver airbag fasteners, replace any missing fasteners and assure that all fasteners are properly installed. If proper torque can not be achieved, the driver airbag assembly will be replaced. GM’s number for this recall is N212343880 and the NHTSA campaign number is 21V-560.
2017-2019 Chevy Bolt EV Battery Fire: The condition is specific to vehicles involved in NHTSA recall 20V-701. Through additional investigation, GM have now identified the cause, and are commencing a new recall to replace defective battery modules in the recall population.
The cause is the presence of two rare manufacturing defects in the same battery cell in design level N2.1 batteries produced at LG Chem’s Ochang, Korea facility. The condition appears to be aggravated by routinely charging the battery to a full or nearly full state of charge after it has been substantially depleted. The battery may overheat, emit smoke and could damage other vehicle components.
Defective battery modules will be replaced by GM, free of charge. Interim notifications are expected to be mailed September 6, 2021. A second letter will be mailed once the final remedy is available. GM’s number for this recall is N212343880 and the NHTSA campaign number is 21V-560.
A small number of 2021 Ford F-150 trucks could experience an electronic brake booster leak. The leak could result in brake fluid entering the electronic control unit (ECU), causing longer break pedal travel, higher pedal effort and reduced braking.
In May 2021, Ford’s Critical Concern Review Group reviewed three F-150 truck warranty claims where brake fluid from the electronic brake booster leaked into the ECU. Ford’s review of supplier records found that the supplier had identified 169 2021 model year F-150 brake booster assemblies in December 2020 because they were potentially assembled with a broken clinching tool, used to secure the pressure sensor to the booster housing. Further review of supplier and Ford records determined that 51 of the 169 quarantined parts were inadvertently shipped to Ford’s Dearborn Truck Plant and assembled into vehicles, all of which were shipped to dealers in the U.S.
Engineering analysis found that a brake booster with an incomplete clinch between the pressure sensor and the brake booster housing can cause brake fluid to leak through the pressure sensor into the ECU. This can reduce braking effectiveness of the brake circuits.
Those receiving notifications will be asked to return to their dealerships to have the ECU replaced. Ford’s number for this recall is 21S33 and the NHTSA campaign number is 21V-533.
General Motors will be contacting the owners of certain 2021 Chevrolet Traverse and 2021 Buick Enclave SUVs, about a problem that could result in the front air bag not deploying properly. Owner notification letters are expected to be mailed out beginning of August 2021.
According to the defect report, during a weekly service programming system (SPS) audit, it was discovered that a small number of 2021 Chevy and Buick models may have been manufactured with the incorrect sensing diagnostic module (SDM) data calibration. The data files were corrected in the SPS system and the problem was reported to GM’s safety program. Their investigation found a small number of 2021 Chevrolet Traverse and 2021 Buick Enclave vehicles may have received the same incorrect data and decided to conduct a safety recall.
General Motors will be contacting the owners of affected vehicles with instructions to update the calibration software in the SDM. GM’s number for this recall is N212340220 and the NHTSA campaign number is 21V-472
In October 2020 Nissan became aware of a problem with certain front steering knuckles and rear axle housing manufactured at their Yokohama, Japan Plant. Nissan conducted a plant audit and determined that a gap in a particular furnace door caused low temperature conditions during the heat treating process. Axle components located in the low temperature area of the furnace experienced an insufficient amount of heat which resulted in poor hardness. These components have been installed on certain 2020-2021 Nissan and Infiniti vehicles.
If the front steering knuckle or rear axle housing receives an impact such as hitting a curb, the steering knuckle or rear axle housing could deform. If the steering knuckle is deformed, the steering wheel may become off-center, impairing the driver’s ability to steer the vehicle. If the rear axle housing is deformed, it will cause wheel mis-alignment.
If the deformation is not detected and the vehicle continues to be operated, the damaged steering knuckle or rear axle housing may cause the wheels to separate from the vehicle.
|Vehicles Affected Include
|2020 Nissan Murano
|2021 Nisssn GT-R
|2020 Infiniti QX60
|2021 Infiniti QX50
|2021 Infiniti Q50
Dealers will inspect and replace the front steering knuckle and rear axle housing, as necessary. The NHTSA recall campaign number is 21V-402.
Owners of certain 2020-2021 Nissan Armada and 2020-2021 Infiniti QX80 SUVs equipped with V8 engines could experience a fuel system problem that could result in an unexpected engine stall. Nissan learned of a potential issue on these vehicles in June 2020 and initiated an investigation which has lead to the recall of approximately 24,000 vehicles.
According to the defect report, the fuel pump module was not designed to manufacturer specifications and could fail. During the impeller manufacturing process, a buildup of molten plastic on the injection moulding machine cylinder tip could cause the density of the impeller to be out of specification. Fuel inside the fuel pump can cause the impeller to swell, increasing friction between the impeller and inlet cover. Eventually the fuel pump will bind internally and the engine will stall.
Owners receiving notices will be asked to return to the dealers to have the fuel pump module replaced. Nissan’s number for this recall is R21A2, Infiniti’s number for this recall is R21A3 and the NHTSA campaign number is 21V-373.
General Motors has decided that a software defect exists in certain 2019-2020 Chevrolet 6500HD trucks. These vehicles have been manufactured with tires that have a maximum speed rating of 75mph (regular production option (RPO) codes XDV for the front tires and YAP for the rear tires) and engine control module software that limits the speed of the vehicle to 79 mph.
In December 2020, Navistar, informed GM that vehicles may have been built with maximum speed limitation calibrations that exceed tire maximum speed ratings. A GM engineering manager reported the issue to GM’s Speak Up For Safety (SUFS) program and preliminary information was collected regarding the issue. GM opened an investigation in February 2021, confirmed the speed limiting software in the ECM and the body control module (BCM) would allow vehicles to reach 79 mph, exceeding the 75 mph maximum speed rating of the tires. In May 2021, GM’s Safety and Field Action Decision Authority (SFADA) decided to conduct a safety recall.
Owners receiving notification letters will be asked to return to their dealers to have the software calibration for the engine control module (ECM) set to limit the vehicles speed so it will not exceed the speed rating of the tires. GM’s number for this recall is N202325530 and the NHTSA campaign number is 21V-346.
In March 2021, Chrysler / FCA USA Vehicle Safety and Regulatory Compliance (VSRC) organization received information about a potential trend in engine fires in certain Jeep Cherokee vehicles equipped with automatic transmissions.
The investigation found the problem to be that certain 2021 Jeep Cherokee SUVs were manufactured with transmission oil cooler (TOC) hoses with rubber that had been incorrectly cured. The suspect period began on January 19, 2021 and ended on March 8, 2021, when all suspect TOC hoses were removed from vehicle production.
According to the defect report filed with the NHTSA, incorrectly cured rubber could allow the hose to weaken and rupture. Transmission fluid leaking from the ruptured hose could contact an ignition source and lead to a vehicle fire. A vehicle fire increases the risk of injury to occupants, persons outside the vehicle and could result in property damage.
Owners receiving notices will be asked to return to their dealerships to have the TOC hoses inspected and replaced as necessary. Chrysler’s number for this recall is Y18 and the NHTSA campaign number is 21V-310.
An investigation into reports of water intrusion into the passenger compartment of certain 2020-2021 Mercedes Benz GLE and GLS, cars and SUVs has led to a recall of over 6,000 vehicles. Owner notifications are expected to be mailed out in June.
According to the defect report, at the end of May 2019 Mercedes Benz launched an investigation into customer complaints of water intrusion into the driver and passenger side foot wells of certain GLE and GLS vehicles. The investigation revealed a deviation in the assembly process of the air conditioner drain hoses that would allow the drain hose to disconnect and condensation to enter the passenger compartment. If a significant volume of condensation enters, it could cause corrosion and/or short circuits to electrical components.
NOTE: Drivers may experience problems with door locks and the vehicles emergency call (eCall) feature; the engine may not start or may enter limp-home mode. Sings that the problem exists include wet carpets in the front foot wells and fogged windows.
|Vehicles Affected Include
|2021 AMG GLE53
Dealers will inspect and correct the installation of the air conditioner drain hoses, as necessary. The NHTSA recall Campaign Number is 21V-288.
