2012 Volkswagen Jetta: adaptive cruise control problems

Filed Sep 29, 2023 · Acceleration, Electrical · TX

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.

I purchased my 2012 volkswagen jetta approx october 31, 2011. Within the first 3-4 months the car computer system locked up while I was driving. (I was unable to put down the windows, the A/C stop working, engine lights lid up on the dashboard) so I drove it straight to the dealership and they immediately apologized and kept the car for several days to correct the defect. In 2013 the steering lock went bad while driving and we couldn't turn the car off. This happened at 6:45pm after the dealership closed. So the car continued running in front of my house from 6:45pm to 7:30am when the dealership opened. I explained to the dealership how frustrating, physically, and mentally draining that night was. We couldn't park the car in a garage and risk the gases getting into the home so we left it in front the house and had to stay up all night and watch it so no one would steal it. They diagnosed it as a bad steering column. The car sometimes accelerate fast on its on when you attempt to use the cruise control. Now currently the sterling lock is gone bad on the car again. I have contacted volkswagen and the dealership several times about this part/issue this year and they told me the car is out of warranty and I would have to pay for the repair. A steering column going bad in a car every year is not normal. My problem is paying for this faulty, defective dangerous car. I have invoice and repair invoice on this car dating back to the first few months of owning it. Volkswagen is on a major coverup to avoid a massive recall of several of the vehicles they knowingly are putting drivers at risk.

On thursday, january 16, 2014, at about 1145 hours, I was traveling sb I-15 in the number one lane, in murrieta, ca in my 2012 volkswagen jetta tdi, with my cruise control set at approximately 77 miles per hour. Without any prior warning, a warning light on my dashboard (later identified as the glow plug light) began to flash and I simultaneously lost power. Luckily, I was able to merge over to the winchester rd. Off ramp. As I slowed and came to a stop, my vehicle stalled and I was unable to restart it after numerous attempts. I was stranded in the center lane of a three lane off ramp where numerous vehicles nearly rear ended me. I immediately called 9-1-1 for assistance. As a result, a highway patrol unit arrived within several minutes to prevent me from being in an auto accident. I telephoned my insurance company after calling 9-1-1 in order to be towed to murrieta volkswagen. Several hours later I received word from the dealership that they found numerous shards of metal in the high pressure fuel pump (hpfp) and gas line. The dealership also informed me that they would be submitting a claim to volkswagen in order to repair the damages, which have been initially quoted at $4000.00. They also told me they would need at least a week to repair the vehicle. I have read numerous accounts online where tdi owners have complained of the exact same issues: finding shards of metal in their fuel filters as well as experiencing a failure of the hpfp. No one else should have to endure the dangerous situation I found myself in yesterday, let alone the expense I am facing if volkswagen denies the claim the dealership is filing on my behalf. Please help all of us. This is a widespread issue that volkswagen has not corrected with their tdi clean diesel engines.

Volks 2012 jetta tdi. At highway speed of approx 55-60 MPH, with cruise control engaged, transmission seemed to come out of gear, engine revved and tachometer red-lined, vehicle began to slow, but obviously not loose power as evidenced by tachometer and high RPM's on engine. After tachometer red-lined, tachometer then began to drop and at about 5,000 RPM, transmission shifted a couple of times and then operation of vehicle was back to normal. Oddly, cruise did not have to be reset and seemed unaware of the event that had just occurred. Entire event occurred in the span of about 5 seconds. Took vehicle to dealer. Service documentation says "we scanned for faults and had a sporadic fault for gear shift control module. Performed test plan and found no problems. We cleared faults." another service showed the error code with verbiage something to the effect of "lost communication with gear shift control module." dealer would not replace gear shift control module and stated that if it happens again, return and they will replace. Clearly this is a safety issue, particularly when it occurs on a highway at highway speeds with congested highway traffic and clearly could have resulted in an accident.
