Volkswagen Group of America, Inc. (VW) will be asking a small number of 2021 VW ID.4 electric crossover SUV owners, to return to their dealerships because of a problem affecting the solder connections inside the HV battery of their vehicles. This defect could result in a stall and may increase the risk of an accident. A fix for this problem is still under development by the manufacturer.
VW became aware of the defect in January 2021 when the first known field case occurred outside the U.S. VW quality and safety departments began to monitor the field reports for the nature and frequency of the non-starting condition and found reports of similar problems in other brand vehicles using the same or similar battery systems. During a multi-brand clearing committee meeting, impacted brands shared information on the potential stall while driving cases and decided to conduct a recall. Volkswagen will be conducting a recall on 351, 2021 VW ID.4 vehicles in the U.S. that contain the potentially affected parts.
According to the defect report, a manufacturing problem with the high voltage (HV) battery may have caused incorrect soldering on specific points of the flexible printed circuit assembly (FPCA). The amount of solder contact points of the FPCA is not sufficient and the thickness of the solder layer is out of tolerance parameters. The result is an unreliable connection inside the HV battery that could lead to a breakdown or stalling while driving. If this issue is present in the vehicle, the driver will be alerted by a high voltage system warning message in the instrument panel.
Owner notification letters about the defect are expected to be mailed by May 13, 2022. Volkswagen’s number for this recall is 9302 and the NHTSA campaign number is 22V-1562.

In August 2020, Volkswagen / Audi received an inquiry about a gateway control module failure in an Audi Q5 vehicle in China. An inspection of the situation found that the gateway control module had gone into fail safe mode because of liquid entering the module from a rear bench seat spill.
The gateway control module has been programmed to go into a fail-safe mode when an implausible signal is detected in the control unit. If an implausible signal is detected, the gateway switches off its function in order to avoid unwanted vehicle reactions. The vehicle remains steerable and the brake system will work, but the engine will go into emergency mode and remains in operation with reduced power.
Audi performed a safety assessment to evaluate the potential conditions and consequences that could result from a power shutdown of the gateway control module due to liquid ingress. Audi also conducted a risk assessment which indicated that the risk of a liquid spill leading to a failure of the gateway control module is very low and rare over the lifetime of the vehicle. At the time there were only isolated cases in the North American region and all of them happened after an outside influence, mostly after a beverage spill. Audi continued to monitor the problem.
In March 2021, Audi experienced an increase in customer reports related to gateway control module failures on Q5 vehicles after a liquid spill. Audi conducted additional testing and continued to investigate a potential solution to be implemented in production and in the field. Due to single field cases alleging the failure without a liquid spill, an additional investigation was initiated to rule out other root causes for liquid ingress. In August 2021 Audi identified a potential manufacturing issue in the factory in Mexico. “Due to a programming error of a glue bead robot, an underbody seam may not have been sealed sufficiently and therefore allow water ingress from underneath in very rare cases when driving through heavy rain or deep puddles.” The adjustment to the robot was implemented immediately and analysis continued regarding the impact of this additional potential cause for liquid ingress.
The Audi Safety Committee began to issue a service campaign in order to install a protective cover for the gateway control module and to seal the underbody in the area of the insufficient glue bead, but after a meeting with Transport Canada and the Defective Product Administrative Center in China, the Audi Product Safety Committee re-evaluated their decision and decided to conduct a voluntary recall to fix affected vehicles.

In June 2021 Volkswagen started an investigation into certain Taos compact SUVs after reviving field complaints of stalling when coming to a stop. The vehicles affected by this defect are equipped with all wheel drive powertrains.
According to the defect report, some 2022 VW Taos with all wheel drive powertrains and a specific software version installed in the engine control unit, could experience a stalling condition when coming to a stop. Conditions such as high ambient temperatures, high engine loads and a running air conditioner increases the chance of an engine stall. The cause for stalling is currently under investigation.
To correct the problem, Taos owners with affected vehicles will be asked to return to their dealers to have the ECU software updated. Owner notification letters are expected to be mailed October 2021. Volkswagen’s number for this recall is 24HH and the NHTSA campaign number is 21V-615.
The owners of certain 2020-2021 General Motors, Nissan and Volkswagen vehicles will be contacted by the automobile manufacturer regarding a problem that could exist with their tires. Continental Tires of America (CTA) have initiated a recall for tires that may have been installed as original equipment on some models.
|General Motors Vehicles Affected
|2020 Buick Enclave
|2020 Cadillac XT5
|2020-2021 Chevrolet Silverado 1500
|2020 Chevrolet Traverse
|2020 GMC Acadia
|2020-2021 GMC Sierra 1500
|Nissan Vehicles Affected
|2020 Nissan Altima
|Volkswagen Vehicles Affected
|2021 Volkswagen Atlas
|2020-2021 Volkswagen Atlas Cross Sport
According to CTA, over-cured tires could experience a break in the sidewall with sudden air loss or could develop a belt edge separation that could lead to partial or full tread/belt loss. These conditions could increase the risk of an accident.
An illuminated airbag warning light in certain 2019 Jeep Cherokee or 2018 Volkswagen Atlas vehicles could mean an airbag crash sensor needs replacement.
ZF North America, the manufacturer of Remote Accelerometer Sensors (RAS) installed in these vehicles, are recalling certain RAS built from a specific production period. According to the defect report filed with the NHTSA, soldering connections inside the sensors may have been damaged due to exposure to higher than expected temperatures during manufacturing. As reported by FCA and VW, if present in a vehicle, an affected airbag crash sensor may not communicate correctly with the airbag control module. If this occurs, the airbag warning light will illuminate.
Warning: There is a risk of delayed airbag deployment during a frontal crash or a risk of a non-deployment in low speed collisions.
Those receiving notices will be asked to return to their dealers to have the air bag crash sensor replaced. Chrysler’s number for this recall is V63. Volkswagen’s number for this recall is 69AL. The NHTSA campaign number is 20E-052.
Brake Parts Inc. is recalling certain brake master cylinders sold under the Raybestos, NAPA and AC Delco brands as aftermarket replacement parts for 2012-2017 Volkswagen Beetle, 2005-2018 Volkswagen Jetta and 2007-2010 Volkswagen Jetta GLI vehicles. (Part numbers MC391232, M4840, and 18M2578)
Sample testing and warranty data show that the crimping of the aluminum housing on the master cylinder may be insufficient. The piston could pop out of the master cylinder housing and drivers could experience a complete loss of braking or unintended braking.
Because the defect would exhibit itself shortly after installation, Brake Parts have instructed their distributors to cover products that have been in service less than one year. The manufacturer is still developing a fix for this recall which is expected to begin August 10, 2020. The NHTSA campaign number is 20E-042.
Volkswagen will be contacting owners of certain 2020 Audi Q8 SUVs, regarding a potential problem affecting the transmission in their vehicle.
Due to a manufacturing error, the flanges of certain gearbox oil pipes were made from an uncertified material. Because of this difference in material, a permanent connection could not be created during the welding process and a transmission fluid leak could develop between the transmission oil pipe and the flange. A loss of transmission fluid will result in oil marks on the ground beneath the vehicle and a warning lamp indicator, once the fluid goes beneath a certain level.
Dealers will correct the problem by inspecting the transmission oil pipe welds and replacing it as necessary. Volkswagen’s number for this recall is 38C7 and the NHTSA campaign number is 20V-272.
Volkswagen will be contacting a small number of 2019 Volkswagen Arteon sedan owners, because of a manufacturing error affecting the braking system.
According to the defect report filed with the NHTSA, the electronic brake booster pressure input rod may have been incorrectly attached to the brake pedal. This incorrect installation may require the driver to use extra braking force and could lead to a disconnection of the pressure input rod. Additionally, in the event of a 12V power failure, the brake performance could be further impaired.
Volkswagen dealers will inspect the mounting of the pressure rod and replace the electronic brake booster and mounting of the pressure rod, depending on the inspection results. Volkswagen’s number for this recall is 47P8 and the NHTSA campaign number is 20V-135.
