This is related to my earlier NHTSA complaint 11771852 for the same vehicle. On 10/16/2026 a Volkswagen dealer ran a diagnostic on a yellow dashboard electrical warning light on my 2021 ID.4 and reported fault codes P0BBD00 (hybrid battery pack voltage variation exceeded limit) and P0AA600 (high voltage battery voltage system isolation fault, sporadic). The dealer found that battery module 6 has uneven cell voltages and needs replacement, and stated that other modules or components may fail in the near future. The warning light remains on, and the displayed range for a given charge level has dropped. Dashboard photos: 10/11/2026 8:03 AM, 65% charge, 109 miles; 10/17/2026 8:09 PM, 73%…

My 2021 Volkswagen ID.4 is subject to open NHTSA Safety Recall 24V-651 (Volkswagen recall 57J9) for the exterior door handles. The recall states that water can enter the door handle electronics and cause a door to open unexpectedly while the vehicle is in motion, which increases the risk of injury to occupants and others. On 10/16/2026 I took the vehicle to a Volkswagen dealer in Tracy, California, specifically to have this recall performed at no cost. The dealerâs own check-in estimate recorded the recall as âverified open.â The dealer kept the vehicle from 7:43 AM until about 11:00 AM and returned it without performing the recall. Recall parts were reported as not available, and the…

High voltage battery modules fail often and continuously. I am on my third battery module replacement of the year taking up to two weeks for repair. There is also a lighting failure when the weather is hot. All lighting system fail and dont turn on until car is driven for a while and the system cools down. This happens often as I am located in florida. During the summer its almost every day. Dealer hasnt been able to fix. All they have said was that VW told them that is due to the UV of the sun. Nothing they can do. I have never had a car fail its whole lighting system when its hot outside. This is extremly important as front lights wont display turn signals while the system is in this…

The SOS/ GPS system in my car failed a few days after the warranty expired. So my car no longer knows where it is and if I press the SOS (Emergency Call) button (or if it was automatically triggered after an accident), it does not work and it does not summon help. I asked VW to cover all or part of the cost as "goodwill" for an important safety system and they refused. Failure of the SOS system (either the battery or the communication module) is a known common failure on VWs and on the ID.4 in particular. VW should recall these vehicles so that this important safety system works.
Mar 6, 2026Vehicle speed control
For approximately the past month, the steering-wheel controls for the vehicleâs Adaptive Cruise Control (ACC) have intermittently become completely unresponsive while driving. When the vehicle is first started, the buttons work normally and can be used to activate ACC, adjust the set speed, and change the following distance. However, after several minutes of driving, the steering-wheel ACC controls suddenly stop responding. When this occurs, the driver is unable to reduce the ACC set speed or increase the following distance using the steering-wheel controls. This creates a potentially dangerous situation because the vehicle may continue traveling at a speed or following distance that is…
