2019 Volkswagen Jetta: start-stop system problems

Filed Nov 6, 2024 · Fuel system · AZ

I was driving and the and the stop start error came on, smelled gasoline and the EPC and check engine lights came on. I kept driving because we were on the freeway and couldn’t quite stop there but my car automatically turned off. The lights stayed on. I was able to turn it off after a few tries and get it to the mechanic (with it turning off a couple times on the way there). After diagnosis, they stated that it is the fuel injectors that need to be replaced because the gasoline and oil are mixing and thinning out the oil as well as potentially cause a fire. Due to that, i now need to replace the spark plugs and replace the oil as well as all 4 fuel injectors. I checked with volkswagon and they stated my car is not on a recall list but I did see there was a recall previously for the fuel injectors. Even if my car is not on the list, this is literally hazardous. The mechanic sent me a video of the oil mixed with gas firing up.

When the 8-speed automatic transmission attempts to shift from 3rd to 4th gear it will slip into neutral causing the engine to redline at maximum RPM. The accelerator pedal does not function and poses a serious safety issue. The vehicle will unexpectedly stall when the auto start stop is used and intermittently requires you to shift into park and restart the engine. The transmission also has difficulty shifting into reverse and puts the vehicle in neutral until it slams into gear.

2019 jetta gli with less than 500 miles equipped with the dsg (automatic) transmission - engine stalls out as soon as the speed of the vehicle reaches 0mph - whether on the highway (bumper to bumper traffic), stopped at red lights, stopped at stop signs, or changing gear to reverse in parking lot or street to get in driveway. The stalling happens regardless of the "auto stop start" feature being disabled or enabled, and happens approximately once every three or more complete stops but usually not for the first 3 when the car is first turned on. The car also makes an audible grinding sound when engine stalls. In all instances once the car has stalled it requires a manual restart by putting the vehicle back in park, and pressing the vehicle start button with brake depressed. In addition to the above stalling, the car has once turned off when started remotely and no passengers inside. I have approached the vehicle approximately 30 seconds after remote start was engaged, opened the truck, loaded a few items, and car turned off. A check engine light came on. Using a vag505 scanner I was able to find 01-engine fault code 15080 and 08-auto HVAC fault code 1048838. Videos of the aforementioned issues have been uploaded to youtube and can be made available via request.

My car is 2 weeks old with 400 miles on the car. Since the odometer had aprox 100 miles on it the car has been having a issue with stalling when coming to a stop. In the past 2 weeks it has stalled aprox 26 times when coming to a stop. I have brought the car back to the dealership for this issue because the car stalled 3 times in a 15 mile drive on the freeway in bumper to bumper traffic. The car is very unpredictable as to when it will decide to stall but becomes a very dangerous situation when commuting on the freeway and it decides to stall. The car is a manual transmission and does not have the auto start stop function but stalls out when coming to a stop. I have informed the dealership that this car is very dangerous to have my family or anyone ride in as you do not know if it will fail and put you at risk of being hit by another vehicle. This is a brand new car and should not have stalling or engine failures at any point let alone having over 20 in a 2 week period. The car is at vw being evaluated but I do not feel comfortable or safe knowing this situation is happening.

Driving a 6 speed m/t. Without auto start/stop, traffic in front of me was slowing to a stop. Slowing down, I shifted to neutral to come to a stop. When stopped, the engine completely shut off and had to be restarted. Has happened twice in the 3 days I've owned.
