The passenger side door actuator/wiring is not locking appropriately. Through the use of the key fob locking the car doesn't lock the passenger door and every time the vehicle is in motion at 10mph it tries to initiate the auto-locking but fails to lock the passenger door. This enables the passenger to open their door at any rate of speed without automatic safety protection. I have seen this be an issue with other Volkswagen Jetta cars online through car parts stores and online forums, but no recalls as of yet. As of right now, I have not had the vehicle inspected but will be looking to do so this week. There were no warning lights or messages that appeared. It just started two days ago and the only way I realized it was a problem is when I would stop and continue driving it would try to auto-lock when I hit 10mph. Concerns arose when I was driving my 8-month-pregnant wife around town.
I was driving on the road going up a hill and my fuel was just alittle low about 120 miles my car sputtered and died and didn't start back up stuck on the road with barley any gaurd rail so I'm partially in the lane and I got it looked at and my high pressure fuel pump failed and sent metal scrapes all throughout my fuel system so it's estimated around 10k to replace I got told it's because the pump barley lost fuel and it uses that to lubricate itself so somthing as simple as one of the pumps going out and this problem can occur or a slight short im just reporting because many others have had this issue with the pump and mine shouldn't have even had nothing going on at 120 miles 1/4 of a tank and I did look in my tank and confirmed I had fuel that I filled up at my local gas station in the middle of the city so it's not bad diesel I own a 2012 volkswagen jetta 2.0l tdi cjaa
The locking system is hit and miss at this time. The automatic locks do not lock all the doors. Sometimes the trunk will not open, either using the fob, or the trunk release. The windows don't always work either. Child lock doors can be unlocked. I am planning on taking it in for service, however, VW charges $165 just to do a diagnostic check and cannot give me a range of what it could cost to repair. I am a senior on a budget. I have seen identical complaints on the internet for this vehicle and cannot understand why there hasn't been a recall. If I spend the money to get this repaired and then there's a recall, do I get my money back from VW?
Horn only occasionally works when honking and/or locking car, which increases the risk of a crash since I can't always use my horn to alert other drivers of presence. One front headlight only occasionally works (lightbulb is not the issue), which increases the risk of a crash since other drivers may not be able to see me as well & I am not able to see the road as well in the dark. Cruise control does not work at all, which increases risk of speeding and therefore increases risk of crash. Dealer has inspected horn/headlight issue but could not determine cause. No warning signs. Issues first appeared a couple years ago.
The contact owns a 2012 Volkswagen Jetta. The contact stated that while his daughter was driving at an undisclosed speed, the air bag warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The mechanic linked the failure to an electrical failure. Upon investigation, the contact discovered NHTSA Campaign Number: 15V483000 (Air Bags) however, the VIN was not included in the recall. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not yet repaired. The failure mileage was unknown.
A microswitch malfunction. My car will not lock and while I am driving it there is clicking on the doors for locking and unlocking. My night lights will not shut off when I park the vehicle. There is a pinging noise when the vehicle is shut off and in park and the door is open with no lights on.
