Selected complaints filed with NHTSA by 2012 Volkswagen Passat owners, lightly cleaned up (personal details are redacted by NHTSA).
I was driving this particular day through a busyfour way stoplight intersection around time school was dismissing so 3:30ish PM. And I lost all power to my vehicle with just the battery light flashing once. I barely made it out of the i intersection and to the shoulder of the road as there was no power steering and i had to pump my breaks to stop. I called the local police and let them know it would be towed tomorrow morning. The tow bill was 100 dollars and i had replaced the battery thinking it was the problem. The brand new battery drained in two minutes tops after install alternator was tested and fuses were in working order all except for one that went to my12 volt charging port which was replaced as well as serpentine belt was replaced with alternator test. The battery still drains instantly and when speaking with volkswagon suntrup in sunset hills st. …
We would have been in a life threating situation (very cold) if we would have not walked down highway to get internet service to look up the issue. What happened. We drove up from Phoenix to the mountains in Arizona. When starting the car after a stop (to look at a heard of Elk in a pasture) the car would not start. It would briefly start for a second then die. The dash lit up with many errors. We were stranded with no cell phone service with night approaching. We walked down the road and got cell service again and called family. Found out from online video while waiting for family to arrive you could disconnect the battery and reconnect to get the car started. We did this and it worked but engine light still was on. Car would not start again next morning and dash lit up. …
The electrical system failed. It has been to numerous mechanics many refusing to do the work. The car cuts off while driving randomly. When ignition is turned off and then turned back on car starts again. No light on dash alternator ecu fuel pump fuses all replaced in effort to try to find the issue with no avail. Car cuts off in mid traffic and then stalls .This is life threatening and should be addressed . No mechanic wants to work on this particular year and model car. Car has been inspected by Volkswagen dealer. No warning lights sounds or dashboard notifications.
I heard a loud crack while turning my steering wheel and now I have an "Airbag Error" message and the controls on my steering wheel do not work. Is this related to the Airbag recall? Is it the Steering Wheel Clock Spring?
This car has automatic transmission and from day one I wasn't un-happy with the fact that you could turn the engine off, without having switched the transmission to p. Every automatic car I ever had and I have driven many including hundreds of rental cars over the years. I reported this in 2012 to the dealer right away when the car was new but was told that this was as designed. I, in between, moved and did the same at 2 other dealers and got the same answer. In 99% of the cases I will not forget to put the car in p, but over the years several times I did. When I left the vehicle and saw it started to move I always was so lucky to jump back in the car and but it in p, or pulled the hand break or pushed the brakes. …
On the 29th of January, upon turning on my car and turning my steering wheel, I heard a "clicking" noise, and immediately on the dash my airbag light displayed along with a message saying, "Error: Airbag". After driving, I realized that my horn no longer worked and the controls on my steering wheel were inoperable. When I arrived at my destination, I began looking up the issue and things that could cause the airbag light to display, along with causing the other issues I was experiencing. The first thing that popped up described a recall that was initiated in 2015 for the clockspring piece failing, which causes the airbag light to display, the horn to not work, as well as the controls on the steering wheel to not work. …
Although this site has my car listed with ZERO unfixed recalls, that is not true. I received a recall notice for the clockspring on this vehicle, called my local dealership and was told it was no big deal, just to have it fixed when I brought my car in for 80k mile servicing. At that time, the clockspring had not yet broken and my car only had 50k miles on it. Late last October, my clockspring broke and I took it to the dealership. They ordered the part but said it was on backorder and it is STILL on indefinite backorder. I have now been driving more than 6 months with NO airbags, NO horn and NO hands free steering wheel controls. The dealership will not give me a loaner until my vehicle is made safe to drive. I have reached out to VW headquarters, the consumer product safety commission and the NTSB. …
Any time it rains and the car goes through a deeper than surface level puddle/wet area where the nose of the car has to dip down (think by railroad tracks, high water retention areas with lack of drainage, etc) as soon as the car dips down into the water, the steering wheel will lock up and I am unable to turn. It's severely dangerous as there is no give at all to the wheel as it is solidly locked and if you happen to be taking a curve or changing lanes etc, you will not be able to turn the car. My husband and myself have narrowly escaped severe car accidents as this is random and there is nothing you can do except try to force the wheel to turn. When I say the wheel is locked, it's a good 15-20 seconds of desperation trying to turn the wheel before it finally unlocks and I am able to correct the direction of the car. …
I own a 2012 Volkswagen Passat [VIN [redacted] ] with approximately 1315xx miles. On December 17, 2025, I took the car to Rockwall County Volkswagen for three recalls. The car was running and was driven 9.5 miles to the dealership under its own power. I left the engine running when I left the it with the service advisor. When I returned to retrieve the car the following day, the service advisor informed me the car would not start. Their explanation shifted within the same conversation - first that someone had shut it off and it would not crank, then that it would crank but would not start. They claimed they had to pushed it into the service bay, replaced the airbag, and "code the computer for the clock-spring." The dealer refused to repair the no-start condition that occurred in their custody. I towed the car home at my own expense - $161. …
Despite performing the regularly scheduled (very expensive) maintenance for this vehicle, we had many issues with our 2012 Volkswagen Passat tdi. This car was a commuter vehicle and was driven 110 miles/5 days per week at 55-65 MPH. We thought that with proper care and maintenance this car with its diesel engine would last more than 111,000 miles... We are so disappointed and frankly irate. What a waste of money. Our issues were: at numerous mileages, our head, tail and running lights had to be replaced at about $50/instance. At 104,738 miles, the passenger window would not go up or down. The window pin was replaced for $184.05. At 101,019 miles, the timing belt was replaced at a cost of $1,260.76. At 111,166 miles, our 2012 Volkswagen Passat tdi began to run very rough and loud on trip. …
