2016 Volkswagen Passat Collision Avoidance Problems

Your car's Front Assist collision avoidance system suddenly applied the brakes while you were driving on a residential street with no vehicles nearby. This has happened multiple times in similar conditions—rainy weather followed by low sun and reflective surfaces like metal plates or bridge gratings. The dealership found no fault with the radar sensor, but you're concerned the system could cause a rear-end collision by braking unexpectedly in these common Seattle weather conditions. Fixing this may require a software update to the collision detection system or recalibration of the radar sensor's sensitivity thresholds.

On October 3rd, 2021 the minder to change oil service came on and a wrench in the display. As the mechanic had set the incorrect timing interval between services, I went into the menu to attempt to reset the service minder but never got that far as the airbag light came on and all buttons on the steering wheel stopped responding. My husband in the passenger seat instructed me to restart the car and this did not reset any warnings but also showed the ACC: Error, in the display alternating with the Airbag: Error. The dealership wants $ 165 just to plug in the diagnostic reader and won't apply it to a repair and says this car has no open recalls which I am aware of. However, there was an airbag recall including the 2015 year build Passat, but the dealership wants payment to diagnose. When the car is stirred to make a 90 degree left hand turn I can hear a coil in the steering wheel cracking at times. Frequently, the airbag light for the passenger scale stays on but may go out if someone goes to sit in the passenger seat. All seat belts are unlocked at the top, and the receivers for the buckles look fine and nothing is stuck in them. I have not yet lifted the seats to inspect the harnesses but I doubt I will be able to fix anything as I cannot reset the codes anyhow. Not being able to change the information on the instrument panel from useless Error Messages is distracting. Tell VW to read an airbag fault light for free! This is a safety concern for every passenger and should not be taken advantage of to make a service department money. How can I find out if this model was added to the air bag recalls or is in the process of being added? Honda has a lifetime warranty service for free on all safety restraints. I am surprised that VW does not make safety their highest priority. I'm not certain the Forward Collision Warning is affected but the lanes blink Orange showing me the ACC is not responsive and it's close enough in function to mention just in case it may not work.

The automatic emergency braking has applied three times while driving this vehicle. Once on a freeway onramp curve in traffic with following car, twice driving on different paved city streets. All three times were daylight and no other vehicle or obstruction in front of my car. This to me is asking for a trailing vehicle to rear end collide, or maybe even worse yet what would happen if this were to happen on rain slick or snow covered road? I did take it to an authorized VW dealer after the second brake application and of course they could not replicate the brake issue. I did not have it checked the first time since I falsely assumed I had done something I had not thought about. Now, after the third time, I am sure that it is the car and not something I have done. I have not been back to VW shop yet after this third time. My wife is scared to drive the car now and I am concerned about myself. I do not think the VW dealer went any further than a test drive and maybe a computer check after the second braking I encountered. There have been no warning lights or messages on my car dash before or after all three times. The dash light warning to "BRAKE!" did light up as the brakes were applying on their own. As a small aside comment, I was a professional highway truck driver with over a million miles driving and achieved a 28 year safe driving record. That has let me make this statement with a lot of "boots on the ground" certainty.
