Sometimes I feel as if my car is possessed I own a 2008 Volkswagen Jetta and sometimes the passenger headlight works sometimes it doesn't I've replaced the bulbs doesn't matter. My sunroof All of a sudden stopped working. My turn signals on the right side don't work when the headlight is not on. I have no sound from my stereo cuz my speakers automatically went out. It has a lot of electrical issues not sure why.
car go into a safe mode take to dealer they said car is no reparable because the part they need is no longer made by VW and is no a substitution part for it. so basically they talk me to send it to a junk lot or I can buy a new car and they will gime some money for it also at the end they recommend a shop that maybe be they can fixit so I think why ???? ia safety advised for a dealer.????
The contact owns a 2008 Volkswagen Jetta. The contact stated that while driving at an undisclosed speed during the daytime, the speedometer failed to illuminate adequately, causing her to be unable to see the speed she was driving. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was unknown.
Passenger airbag is always off. I saw reports on youtube wiring connectors under the seat are the reason. There's a home remedy solution. Important air bag issues should be freely be done by manufacturer or dealer. Also steering issues are more common than reported. The electrical devise fails too often rendering driving the vehicle difficult.
The ignition switch gets stuck sometimes and I can't crank my car nor turn it off I'm just dating that because that's what's going on on my end. Therefore, I've had times where I can't crank my car or I can't turn it off when I need to. So you may tell me if there was a recall on ignition switch or whatever
I first started experiencing this problem with the rear passenger door on my vw Jetta in December 2015. The door would not lock using the key remote. I have to manually lock the doors by pushing the key into the driver side door in order to get a beep sound and flashing indicators to confirm that all the doors are locked. I took the car to the vw dealership which cost $480 to fixed one door. About four months after fixing the door, someone broke into the car which I later found out that the driver side rear door lock also failed and wasn't working. The difference this time was, manually using the key would only lock three doors (2 front door and passenger side rear door, which I had fixed prior to the second failure). I took the car to the dealership again and had to pay another $480 to get it fixed. …
Just after I purchased the used vehicle from a private party, I was driving on the interstate at approximately 70 miles per hour, when the vehicle without warning slammed into second gear, sending my face into the steering wheel, while the cars travelling behind me had to brake to avoid collision. I pulled over, and turned the car off to assess the reason, to no avail. When I re-started the car and put it in gear, it drove fine until the next time I drove it. Then it did a repeat of the previous action, sending the transmission into safe made without any notice or provocation, and again, when I restarted the vehicle it drove perfectly normal while I drove it directly home. When I performed an obdii scan, it generated p0746 as the problem, with no other problems being reported. …
While the vehicle was in motion on a highway, the turn signals began to act erratically. Initially only the left turn signaling appeared to be affected, and would fail to make any indication on the dash or illuminate the lights. Shortly after this, attempting to signal a right turn would actually result in the left turn indicator lights illuminating (yes, the opposite of what was intended). As I am one of the individuals dealing with the door control issue, I am unable to use my window. I could not use arm signalling to make my intentions clear to other drivers. It was very difficult to change lanes on the highway. I believe that there was a similar issue, and associated recall, with the 2002 Jetta turn signal indicator/switch.
I was driving to work one morning and it started to smell like something was burning. I thought maybe it was just a weird smell in my vents but within 10 minutes of driving a cloud of smoke filed the driver side of my car. Luckily I was not on the highway yet and I was able to pull over and shut off the car. Not knowing where the smoke came from I immediately got out of the car. It when then that I looked down and saw the source of the smoke, there was a quarter size hole in my driver seat. I had been driving with the seat heater on and it caught fire. Luckily I was not injured and was able to quickly get off the road and discover the issue however I have read other complaints of similar events and yet no recall.
