2021 VOLKSWAGEN ID.4 Forward Collision Avoidance Warnings Problems

I was pulling into street parking spot behind a parked car at a slow speed and braking to stop. I put my foot on the brake to bring the car to a complete stop but instead of slowing down the car accelerated straight into the vehicle in front of me. The rear end of the car in front of me was substantially damaged.

I was driving my 2021 Volkswagen ID.4 Pro S on March 12, 2025, in Baltimore, Maryland, when I was involved in a motor vehicle accident. Although I maintained an adequate stopping distance from the truck in front of me, my forward collision warning, lane departure warning, and lane keeping assistance systems suddenly activated, causing my vehicle to make contact with the truck. My safety—and the safety of others—was compromised. My vehicle sustained front-end damage. This was not the first time these systems engaged without cause. I took my vehicle to Heritage Volkswagen Parkville (located in Carney, Maryland) due to unresolved recalls and these irregular system behaviors. The dealership claims that Volkswagen requires me to replace the tires, align the wheels, and install a new 12V battery before completing the recall work or troubleshooting the issue. I informed the service manager that the vehicle is unsafe to drive and that, under...

I was driving on a highway using the cars adaptive cruise control, when the car suddenly without warning slammed on the brakes. This caused me to be rear ended by a car behind me. The automatic emergency braking system had triggered without any hazard in front of me. Although there had not been a warning light of a malfunction, the car had previously activated phantom emergency braking. Previously the car on several occasions the cars AEB system activated but only briefly applied the brakes before quickly disengaging and the AEB warning went away. However, this time the brakes fully activated causing the car to stop abruptly from 50-60mph to a stop. I have not yet reported the issue to the dealer and no one has yet inspected the vehicle. Although no one was hurt, this issue could have caused very serious injuries and did cause significant damage to my vehicle...

The contact owned a 2021 Volkswagen ID.4. The contact stated that while driving on a highway at a moderate speed, traffic came to a sudden halt. The vehicle's forward avoidance collision feature was activated; however, the feature did not perform at full capacity and hesitated to fully stop. The contact repeatedly pumped the brake pedal; however, the vehicle independently accelerated and crashed into the vehicle ahead which resulted in a five-vehicle accident. An unknown red warning light appeared on the instrument panel during the failure. The air bags deployed upon impact. Upon air bag deployment, the contact sustained burns to the left thumb and chest; additionally, the contact experienced soreness to the cervical spine, neck, both knees and ankles. The driver of the vehicle which the contact directly hit also sustained a sore neck but neither driver sought medical attention. The vehicle was towed to an independent mechanic where the...

1. The brake pedal freezes intermittently when I step on the brake. 2. The sensor is faulty - it flashes red and warns me that the brake isn't working. 3. In autonomous driving mode, it did not detect the vehicle in front of me and didn't slow down. 4. After driving in the rain, the front brakes seized up. VW of Wellesley in MA said they fixed these issues, but I continue to experience 1 and 2. It hasn't rained so I couldn't test #4. My car was in the shop from [XXX] to [XXX] this last time. Previously, it was there twice for shorter time. #2 first happened when my car was new. I mentioned it to the sales guy and he said the sensor was probably blocked. It kept happened but when my car stopped detecting the car in front on the highway, I knew something was wrong....

the driver door open by itself during driving. It happened 3 times. It is not possible to lock the car. I had called the dealer ship. On my first call the said i will be on the list. After 3 weeks i called again then they said they didn't have the parts to make the repairs. I have asked for the manager to call back and it never happened.

I have an id.4 (VIN: [XXX] ) which has recall issues. I've been trying to get this rectified but have been told there is no resolution for the past 6+ months. yesterday both my speedometer and main (entertainment) screen went blank. I called the dealer and was told they do not know what the issue is, but the vehicle is safe to drive since it "works". I do not know what the speed is, and I get warnings that none of the sensors work (front, airbag, speed control, etc...). I contacted VW corporate and was told this is a dealer problem. I keep getting put in between the corporate office and dealer with no resolution, yet I paid 50k for car that isn't safe for my family (I have a 5 year old). What am I supposed to do? Also VW dealership said they can take the car in, hold...

While traveling at highway speeds I suddenly got multiple warnings of the parking brake becoming inoperative, Auto Hold Error, and Travel Assist and Cruise Control no longer available. When trying to park the vehicle's parking brake would not engage and a loud warning sound and red warning message with "Do not park vehicle on an incline" came up on the dash. The vehicle was not able to be parked on any surface without it potentially rolling away. When trying to take the car into the dealership on Monday, 9/11/2023 the vehicle would not move out of "Park" and had be dragged out of the garage it was parked in.

It happened to me at least 3 times. The first one happened Oct, 2021, when I did not realize it is a big serious problem. The other two happened in Aug 2022 and Oct 2022, respectively. All the three incidences took place after I charged my vehicle in a hot environment exposed to scathing sun shine. The drive assistance and sensor were not working, the cruise function did not work, and the road sign reading feature was not available. Several warning signs about those functions and features showed on driver's console. I was driving on Highway 15 or Highway 405 and of course I could not stop and check. However, after driving like 15-30 minutes, these features go back to normal. I suspect the sensors that make those functions and features work cannot handle the harsh temperature well.

The Driver Assistance feature of the car shuts down due to a Software error. It will eventually reset if the car is parked and turned off for a duration of 30 to 60 minutes. Some users have reported that the error does not clear without disconnecting the 12v battery. Problem first appeared in the id.4 2021 models in the summer of 2021. VW has issued a software correction for the vehicle in Europe, but that update has not been made available for the US customers. This causes the collision avoidance system to go offline and the driver is warned to drive with extreme care! In some cases the vehicle speed also stops displaying.
