  • 73,000 miles


The contact owns a 2012 Volkswagen Jetta. When starting the vehicle, the epc warning light illuminated and the vehicle stalled when attempted to drive. The vehicle was towed to the dealer where the failure code was cleared for the ABS fuse. In addition, while driving 60 mph, the brake light failed. The vehicle was taken to the dealer where it was diagnosed that the brake switch and brake booster failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 73,000.

Car's fuse # 6 keeps blowing which controls the back lights that turns on at night, when fuse blows lights on back go out and cars behind you can't see you and may cause a collision where serious injury and death may result. I think this an engineering flaw where they connected the back lights to other modules in the car, so the short remains and car is not safe to drive at night fuse keeps blowing every time you put a new one in VW is not willing to look at the problem and give me a solution, the short is not in any of the lights on the back of the car, or inside the car, VW is refusing to give me the schematic diagram for that circuit so we can trace the problem, they insist on taking it to the dealer where it is going to be a very expensive fix to track down the short where it is an engineering flaw. Also the air bags warning lights come on intermittently, and seat belts warning lights come on and start chiming while you have seat belts on and properly fastened, do not know if seat belt or airbags are defective which is very unsafe in my opinion, and VW refuses to look at my problem without a hefty dealer charge. Please help

Driver side bulb keeps burning out. Was replaced by dealer with oem parts, but it keeps burning out every month. The daylight running light on the driver side does not work. They keep replacing it and it keeps burning out. I see many other Jetta's like mine with the same problem on the road.

Both of the low-beam headlights stopped working as I was driving home on a unlit highway at night. The daytime running lights worked when I turned off the headlights, and the high-beam headlights worked when I tried using them. The next morning I replaced both low-beam headlights and they still do not work.

Vehicle has 38,000 miles, we're the original owner, horn became intermittent, then stopped working. We took it to the VW dealer in brandon, fl. They said there's a recall about to be announced in November that will cover the horn, and the potential for an airbag earning light. We're left with major safety hazard with not having a horn. The dealership said it would cost over $2000 to fix, they won't have the parts until the recall is sent. This can't be right and feel we're being put at risk while they figure out what they want to do.

2012 Jetta tdi. Horn intermittent and about the same time my moon roof stopped working. As a military member stationed near seoul, South Korea, I was in heavy traffic and someone pulled out in front of me even though I was a low speed I still had to smash on the brakes causing the anti-skid system to work. As soon as they pulled out in front of me I was pressing the horn and nothing happened. I believe this is a major safety defect with many people having issues with faulty horns/wiring, especially for a car with less than 50K miles on it. (conveniently out of warranty). I am aware of the recall on the horn for the 2011 models, obviously they didn't resolve the problem when building the 2012 model. In seoul I feel the need to use my horn daily as there are over 150 accidents a day just in the seoul area. This is a major safety issue and should be covered by VW.

The key locks in the ignition while the car is running and in park, will not disengage to turn the car off (steering wheel not locked). I was unable to turn my car off. This first occurred while I was parked in a parking lot (no danger). After the dealership forced the key, I had to pull over to the shoulder on a highway for a flat tire and was unable to turn the car off. I could not change the tire safely and could not get the car towed as I could not turn the engine off. I had to sit at the side of a highway until my car stalled from running out of gas, until I could safely have the car towed. No locksmith was able to correct the ignition lock, as it is an electronic lock in the key housing. I see multiple complaints listed with NHTSA regarding the same issue with VW cars, and many specifically for Jettas, and 2012 Jettas.

The first time my radio caught on fire, it was the summer of 2014. My car was parked in a parking lot while I was at work. When I entered the car to drive home, I turned started the vehicle and there was a extremely loud sound, much like an explosion. The middle dash where the radio is located began pouring smoke. After the incident, I contacted the dealership, who "fixed" the problem (they replaced the stock radio for another VW stock radio). Spring of 2015, the same exact thing happened. My car was parked at work, I started the car and the radio began pouring smoke. I again, had the issue "fixed" by the dealership. August 2015, again this happened and September 2015 again. When I insisted that VW must further investigate the underlying issue, they claimed to have fixed the problem after the August 2015 incident. With this incident not only did the radio burn out, my battery was drained out. The explanation I was given was that the power line to the radio was not shutting off, therefore the radio was overheating and the battery was being drained. With this particular incident, I received my car back on a Monday and the radio again caught fire and burned out on the Friday of that same week.

On several occasions the ignition will not turn off. The key is stuck in the on position and can not be removed. On one occasion it took over 7 minutes to remove the key. This may not seem like a long time, but sit in your car after parking then time 7 minutes and you'll see how frustrating this is!

The vehicle was being backed out of a driveway into the roadway when the horn began to sound continuously and the airbag warning light illuminated. The vehicle needed to be turned off completely to stop the horn. Subsequently, the horn sounds whenever the ignition is engaged sometimes stopping once the engine turns on, sometimes not. Once started the vehicle is driveable but the airbag warning light is illuminated, the horn on the steering wheel is inoperable and the steering wheel controls are inoperable. The vehicle was taken to a Volkswagen dealership and diagnosed with a faulty clock spring that requires replacement. The incident appears to be similar to that described in NHTSA investigation PE 15-010.

For this year of Jetta the doors lock around 10 miles an hour. Mine does not lock. The doors will keep attempting to lock with no success. If you go on a long trip and slow down to the 10 mph range they will try to lock again. The door also does not lock when you push button. You must keep pressing it until it finally locks.

Upon returning home on Sunday 12/21 at 3 pm, smoke was coming from our garage. We opened the garage door to discovery my car on fire and a garage full of smoke. We called 911 and requested fire assistance. We then proceeded to extinguish the fire using 5 commercial size fire extinguishers. The fire department arrived and extinguished the flames and dragged the car from the garage. The car had not been driven for approximately 18 hours.

The horn on this vehicle becomes unresponsive at times. When it does work, the horn tone is very low and is difficult to hear. This could be a safety issue. It also concerns me since an operational horn is needed to pass the state safety inspection. I have not taken it to the dealership yet for repair, but a quick internet search, I have confirmed this is far too common problem on newer model Jetta's.
