Filed Nov 2, 2026 · Electrical, Fuel system · CA

Update to my the federal safety agency complaints 11772122 (battery, October 19, 2026) and 11771852 (door handle recall, October 17, 2026) for my 2021 Volkswagen ID.4. What failed: the high voltage battery and charging. On November 1, 2026, the vehicle either did not charge or stopped charging with about 38 miles of range. On November 2, 2026 at 9:32 AM it showed 8% and 15 miles while charging. Cause: UNKNOWN. Confirmed by a dealer: yes. On October 16, 2026, a Volkswagen dealer's diagnostic found fault codes P0BBD00 (battery pack voltage variation exceeded limit) and P0AA600 (high voltage isolation fault, sporadic) and uneven cell voltages in battery module 6, which it said needs replacement. The vehicle is available for inspection on request. Warning lamps: an amber warning triangle and a yellow vehicle warning symbol are on. They were already on in my October 11, 2026 photo. When they first appeared is UNKNOWN.

The vehicle developed a charging/electrical/high-voltage battery problem. Level 3 charging stopped first, then charging later stopped on all levels. The vehicle was taken to an authorized Volkswagen dealer on 08/06/2026. The dealer referenced high-voltage battery/module and charging-system issues, including fault/code information involving P0BBD00 / J840 / 008C and campaign/action history involving 93P7 / 97ZZ. The dealer quoted a very expensive repair involving a high-voltage battery/module condition and charging-system components. The unresolved safety concern is that the dealer/manufacturer have not provided a clear written answer on whether the vehicle can be safely charged, operated, towed, released, or repaired elsewhere while the high-voltage battery/module condition remains unresolved. They also have not clearly answered whether the charge-door / charge-port / connector-lock / socket / AX4-J1050 issue is separate from the high-voltage battery/module condition or whether it caused or contributed to the no-charge condition. The underlying diagnostic output, measured values, DTC/freeze-frame data, campaign/action history, technician notes, and written safety/repair-path explanation have been requested but not provided in the form requested. I am concerned the vehicle may have an unresolved high-voltage battery or charging-system defect and that prior/current campaign handling may be relevant.

The infotainment screen and heads up display screen are constantly going black and rebooting, causing a loss of the speedometer for up to a minute at a time. Occasionally, the entire vehicle loses power and the accelerator does not work for a few seconds. The shop says it is the 5F control module, which was described by the dealership as handling one half of the high voltage current, as well as controlling the infotainment screen. If this module is responsible for half of the high voltage current, I don't understand why they claim it is not covered by the 8 year/80,000 warranty on the high voltage battery and related components.

My 2021 Volkswagen ID.4 Pro S has unexpectedly lost propulsion and come to a complete stop while being driven on at least three separate occasions. When this occurs, the vehicle jolts, stops moving, and cannot be placed into Drive or Reverse. I am only able to shift it into Neutral. After the first incident, I took the vehicle to a Volkswagen dealership the following morning. The dealership stated they could not reproduce the problem or identify any faults. The same failure occurred twice in one day this week. During one of those incidents, the vehicle lost propulsion and stopped in the middle of a busy street, creating a serious safety hazard because I was unable to move the vehicle out of traffic. Immediately before and during the failure, the vehicle displayed multiple warning messages, including: Error: Drive system. Please safely stop the vehicle. Electrical system not working correctly. Please service vehicle. Error: Electronic Stability Control (ESC). Front Assist is not available. Lane Assist is currently not available. Rear Traffic Alert is currently not available. Park Distance Control is not available. Error: Auto Hold. These warnings appeared at the same time the vehicle lost propulsion. The vehicle stalled without warning while driving and became undriveable. This is extremely concerning because it can occur suddenly in traffic, placing the driver, passengers, and surrounding motorists at risk of a crash. The vehicle is currently at the Volkswagen dealership for inspection, and I am awaiting their diagnosis. Because this dangerous condition has now occurred multiple times, I am concerned there is a serious defect affecting the vehicle's drive system or electrical system.

The vehicle was engulfed in flames and destroyed. An inspection of the vehicle and battery modules in October of 2024 by VW experts and experts for the driver determined that the fire started in one of the battery modules and was not due to external causes or road hazards.

I got out of my car on Saturday, April 20th at a shopping mall 50 miles from my house. I parked and my screen told me that I had an over the air software update that I needed to install. I began installation of the update and parked and left my vehicle. I returned approximately 2 hours later and the car would not shift into drive. I had a yellow error message that said my cornering light was not functioning properly, but nothing referencing why my car wouldn't go into drive. I sat and tried to troubleshoot for another hour before calling roadside assistance. I was away from home, so they explained that they would only be able to tow it to a nearby dealership. It was after hours, nothing was open and it wouldn't be open until the following Monday. I paid almost 500 dollars to tow the vehicle to my house and then paid another 100 dollars through AAA to tow it to the dealership on Monday morning. Since then, my car has been at the service center and has not been repaired. They gave me a loaner but it's been almost 30 days and no resolution. I have been told that the issue was related to a known recall. I contacted VW to discuss a Towing reimbursement and was informed that VW would not be covering the expenses for either Tow event even though the first was completed under their Roadside assistance program.

These recalls are old: February 7, May 5, and August 25 of last year. My local dealership, Hansel Volkswagen, 2951 Corby Ave, Santa Rosa, CA 95407 (1‑707‑578‑1320), is unable to get the parts for these repairs from VW of America, even though WV of America is steadily building new cars. My 2021 ID4 is still not repaired.

With the vehicle in 'B' mode, I started acceleration in a moderate fashion. After about 30 feet the car lost power. Pressing the accelerator further had no effect. Releasing the accelerator then pressing it immediately power was restored. The car has been to the dealer twice for this issue. Neither time could it be duplicated. It has happened five times in the past two months with the last incident almost resulting in an accident.
