Volkswagen Jetta fuel gauge problems

Filed Oct 4, 2025 · Electrical, Fuel system · MI

I purchased a brand-new 2025 Volkswagen Jetta from LaFontaine Volkswagen of Dearborn, MI on October 2, 2025. Within 24 hours, the check-engine light illuminated, and the fuel gauge cluster froze, showing an incorrect fuel level. On October 3, 2025, I contacted the dealership and was told to bring it in for service. The service department confirmed a faulty Transmission Control Module (TCM) and opened a repair order. Before the repair could be completed, the vehicle became inoperable and would not engage Drive, leaving me stranded in my driveway. The car had less than 350 miles on it at the time of failure. This incident is extremely concerning for a brand-new vehicle and raises questions about potential safety and manufacturing defects in the 2025 Jetta model line. A new car’s transmission should not fail within days of delivery. I have filed related complaints with the Michigan Attorney General and Better Business Bureau regarding the dealership’s handling of the issue and lack of transparency. Please investigate potential defects in the transmission control system and electrical fuel cluster of 2025 Volkswagen Jetta vehicles to prevent similar failures from occurring with other consumers.

Whenever the outside temperature reached 85 degrees Fahrenheit or higher, all computer systems and electrical functions would shut off. If I was driving at the time, the engine would continue to run, but I wouldn't be able to use even the most basic functions -- blinkers, hazard lights, radio, air conditioning -- and all the gauges on the dashboard -- speedometer, gas gauge, etc. -- would stop working, creating a dangerous driving experience. If the car was already parked, or I came to a stop, the ignition would flutter and then shut off as soon as it was put into gear. And only start working again after the car had cooled down, oftentimes by having to dump cold water on the vehicle, or by parking it in the shade for an extended period of time.

The vehicle steering has been off and alignment when driving. My gas gauge has been off constantly, since I've owned the vehicle. I documented this many times and reported this to the dealership under warranty and Volkswagen care.

My jetta stalls without warning when the gas gauge is at a quarter of a tank or less. No engine check light or any other any other device comes on to warn me it is going to stall. My speed does not matter. It happens at freeway speeds or around town. It does not occur if the gas gauge shows more than 1/4 of a tank of fuel. I do not know if it is an electrical problem, a fuel propulsion problem or an engine problem. From reading volkswagon forums, this is a very common problem with volkswagons of different years, including the new Tiguans. I'm sure there have been many fatalities as a result of this defect. I am surprised volkswagon has not been forced to repair this dangerous, life threatening problem before now! Maybe, a class action law suit involving products liability, merchantability, and fitness for a particular use would benefit not only owners, but the general public at large. I believe it is your duty to protect the general public from manufactures who place dangerous, defective products in the stream of commerce. Your action is required, and demanded. The first time ocurred right after I purchased the car in 2019. It has stalled many times since then, before I realized I needed to keep the fuel tank at least 1/2 full at all times. Keeping it 1/2 full at all times greatly deminishes the range of travel before I have to refill. It is inconvenient and expensive since fuel has to be purchased at places other the most economical place I usually purchase my gasoline. Thank you

Ever since I purchased my vehicle one year ago, I noticed that my car has trouble starting. It is a push-to-start car, and sometimes it cuts off and I have to push the button to have it restart. It happens during all types of weather, and I've had the batter tested at the dealership and it was in good standing, and they couldn't figure out what was wrong with it. I've also had to replace the tires multiple times over this last one year of having the car. The first time I had to do that was literally within two weeks of buying the car. Furthermore, the range feature that gives you an automatic reading of the gas gauge is inaccurate. When I fill up the tank if sometimes reads over 300 miles, and then sometimes it reads over 400; and then when the gas is low and nearing empty, it notifies me at 30 miles left till empty but then rapidly drops to 15 or less by increments of 5.

Tl* the contact owns a 2010 volkswagen jetta. While driving 65 MPH, the ABS indicator began to beep. The contact applied the brakes, but the brakes did not slow the vehicle down initially. The vehicle eventually slowed down and the contact was able to pull over to the side of the road and stop the vehicle for fifteen minutes. The contact slowly drove home with the ABS and other unknown indicators flashing and the fuel gauge needle moved back and forth erratically. It took the contact hours to drive home. Gunther volkswagen of fort lauderdale (1660 s state rd 7, fort lauderdale, fl 33317, (954) 797-1660) informed the contact to leave the vehicle for diagnostic testing.

The car stalls while driving at any speed or while idling when the fuel gauge is around or under 1/4 of a tank. I have read up on this and people are dumping a lot of money onto trying to figure out what the issue is and there is no answer. Stalling on a highway without a median or pull-off is not only inconvenient but dangerous.

While maintaining speed at or above 40 MPH and with 1/4 tank or less of fuel remaining, my jetta will consistently stall out and turn off from fuel starvation. This has happened to me between 40 and 80 MPH several times, both in the city and on the highway. I have replaced the crankshaft position sensor, the fuel sender, and the fuel pump with no success. Additionally, the jetta will die the first time I try to start it as my fuel level approaches 1/4, especially if I am parked on an incline. However, it never fails to start on the second try once some fuel has begun moving through the system. Fully refueling alleviates all problems.

In april of 2016 car just had 6 indicator lights on dash. Just happened one day on the highway. Speedometer, gas gauge none of the dash worked. Red light constant flashing. We ended up having to park it for 6 months while still paying 300 a month car payment and full coverage insurance until I had money to fix it. Around the same time the back passenger window stopped working and still doesn't work. I got this car in march of 2015 I believe. It has cost me so much money and I am hoping that I may be able to get a reimbursement on the 800 I spent to fix it, only to have it do this stuff randomly every few months. Just 2 weeks ago I had to slam on the brakes while driving and there was a bang sound and I drove it home. The next day it drove to work ok and then on way home when it started it immediately was running badly and check engine light and all that was on again. We took it to mechanic and he said thermostat was stuck open and it did need a coil and wires or something also. It has been just constant with this car and I am spending a ton of money. It's really difficult raising a family and working 30 miles away from my home and dealing with this constantly. Oh, and the air conditioner only works in the winter time. Definately not when idleling. Mechanic says that's a 400$ part so I'm just trying to scrounge up the money to fix that part of the electric disaster this car is before it hits 101 on my days sitting in traffic. Please help. The document I have to upload is the reciept from the repair. It was messed up for almost a year before I could fix it. Mostly just sitting.

As I drove home one night, the fuel gauge was showing empty when I knew that the tank was half full. This is dangerous for a remote, rural driver who needs to know how much gas is left in the tank. Nothing out of the ordinary was present for this occurrence. After I turned the car off and turned it back on the gauge was back to normal. I will be monitoring closely from here on out.
