12-volt onboard battery error codes, stating battery charge is low, and to safely park the vehicle. Alternatively, drive the vehicle to charge the battery. Or charge the vehicle. The car has been to the dealer for testing, and they say that the on-board battery checks out without any problems, yet I continue to get the battery error codes. We don't feel safe to driving the car in fear of complete lockout failure.

While entering a parking lot at a low speed, with my foot already firmly applied to the brake due to the close proximity of a parking space, the vehicle suddenly accelerated on its own unexpectedly. Despite continuous pressure on the brake pedal, the vehicle proceeded forward, struck another parked vehicle, and continued moving for approximately two additional seconds before coming to a stop on its own. Additionally, no forward collision/crash warning alert was activated prior to impact, and the airbags did not deploy during the collision.

The infotainment system in my Volkswagen ID.4 is experiencing intermittent failures while driving. The issue primarily affects the vehicle’s connectivity with my mobile phone (Apple CarPlay / Android Auto), music playback, and the use of navigation applications such as Google Maps. In several instances, the central display has also gone completely black, temporarily becoming unresponsive without warning. The affected component is the vehicle’s digital infotainment system, including the central touchscreen, Bluetooth connectivity, and multimedia and navigation functions. This system is available for inspection upon request. While driving, the system randomly disconnects from my phone, which interrupts Google Maps navigation, music playback, and other phone-based functions. This is particularly concerning because I rely on Google Maps for daily navigation, as the vehicle’s built-in navigation system is not sufficiently accurate or reliable. In my experience, the factory navigation does not provide strong real-time traffic detail and sometimes routes me through significantly longer or less efficient paths. The only advantage of the built-in navigation system is that it displays information on the driver’s head-up/front display, which Google Maps does not support. These failures create a potential safety risk, as the sudden loss of navigation while driving can lead to distraction when attempting to reconnect the phone or restore system functionality. Additionally, interruptions in audio guidance and the occurrence of a completely black screen may further affect driving focus. The issue occurs intermittently and has happened multiple times during normal vehicle operation. It is not consistently reproducible. To date, the vehicle has not been inspected by a dealership, the manufacturer, police, or any insurance representatives in relation to this issue. In most cases, there are no prior warning lights or messages; the system simply disconnects or the display goes bla

I was stopping by my house to quickly pick up something so I pulled into my driveway and clicked the Park button. I heard the reassuring click from the button which usually indicates that I had successfully clicked the button and that the parking brake was engaged. I let go of the brake and looked down at my phone but I felt like the vehicle was starting to creep toward. I looked up just in time to realize that I was rolling towards my opening garage door so I slammed on the brakes before any damage occurred. This was one of two scenarios where I experienced this issue. Another time I experienced the issue happened when I pulled into a supermarket parking lot. I clicked the Park brake and proceeded to undo my seatbelt and exited my ID4. I felt the vehicle slowly roll away but then I heard the parking brake engage (it was the ID4's safety feature to engage the parking brake when it detects that the driver has left the seat). Thankfully the ID4 had barely touched the curb so no damage happened. These incidents cause me to now click the parking brake multiple times to ensure that the vehicle has actually engaged the parking brake. I believe this might be a button issue that happens once in a blue moon because every time I try to recreate the scenario by clicking the button lightly, it had always properly engaged. I will inform my local dealer the next time this vehicle is due for maintenance but until this issue is fixed, I will spam the park button.

The 2023 Volkswagen ID.4 experienced a high-voltage battery system failure yesterday while DC fast charging, about two weeks after the vehicle underwent recall/campaign service related to high-voltage battery monitoring and software updates associated with NHTSA Recall 26V030. During charging, I heard a loud popping sound from the charging port/high-voltage battery area. After disconnecting from the charger, the vehicle displayed warning messages stating: “Electrical system not working correctly. Safely stop the vehicle!” and “Error: 12V power supply. Safely park the vehicle! See owner’s manual.” The Ontario California Volkswagen dealership informed me that a high-voltage battery fuse/protection component malfunctioned or blew and that the vehicle now has to be manually de-energized and partially disassembled to determine the cause of the failure. The vehicle and failed components should be available for inspection through the dealership. I believe this created a serious safety risk because the failure occurred during active DC fast charging involving the high-voltage battery system. I am concerned about fire risk, sudden loss of propulsion, or other high-voltage battery hazards. The issue has been preliminarily confirmed by an authorized Volkswagen dealership, and I was informed Volkswagen engineering representatives may need to assist with the diagnosis. Prior to the failure, the vehicle had recently undergone recall/campaign service on 04/28/2026, and I was informed the battery control module software required multiple sleep cycles to complete the update process. The dealership is charging me approximately $2,000 in diagnostic and battery teardown fees while determining whether repairs will be covered under warranty. I believe the failure may be related to the recall, software update, or a defective high-voltage battery system and I am requesting Volkswagen consider a buyback or other appropriate remedy.
