Warning Problems of Volkswagen Jetta

This update is for odi #11761839. I am submitting new diagnostic evidence confirming that the acc/travel assist safety defect in my 2025 Volkswagen Jetta continues to occur and existed long before any accident or windshield replacement. On August 18, 2026, a certified adas technician performed a full diagnostic scan and documented u112300 databus errors and c12b3fd temporary camera view limitation. During the test drive, the technician successfully reproduced the travel assist failure (“travel assist not available”). The technician also wrote: “owner is having issues with the acc intermittingly since pick up. He took it to the dealer, but they were not able to find any faults. ” this shows the defect existed from initial delivery and is not accident?related. The technician also identified NHTSA TSB mc?11007395?0001 (48?23?01), which may apply to 2025 models and describes potential hardware or software deviation in the steering wheel hands?on detection system. After windshield replacement and both static and dynamic adas calibrations, a second diagnostic scan on September 1, 2026 showed the defect persists. The acc module still reports u112300 databus errors. Additional communication faults were found in the instrument cluster (u111000), gateway module (b184c00, u17a000), and electronic central electric module. The front camera also reported an internal malfunction (b200ff0) despite successful calibration. These results demonstrate that the issue is caused by internal electronic/communication failures, not the windshield or calibration. The acc/travel assist system continues to fail during normal and highway driving, creating an ongoing safety risk due to sudden disengagement. I request that this evidence be added to my existing complaint and that NHTSA continue its investigation into this unresolved safety defect.

Travel assist is disabled which includes adaptive cruise control and lane keep assist. The warning lights flash on and off, sometimes multiple times a second, sounding a loud beeping each time. It is triggered at engine start and persists through all speeds. I have experienced it 0-70 mph. The flashing lights and associated rapid beeping indicating the failure is extremely distracting while driving. Warning lights and warning sounds are designed to alert the driver to a potential safety issue so ignoring the lights and sounds is dangerous in the event it is a different caution/warning. However, also not ignoring it is dangerous because of the frequency of the warnings which causes the driver to look away from the road. After speaking with the maintenance department at my vw dealership, they indicated that this is a widely known problem that is remedied only with the replacement of the steering wheel. There are several other sensors that are triggered by the same issue I was told by the maintenance department. They are uncertain at this time if it impacts the airbag system which is another potential safety concern. The steering wheel can only be ordered after inspection by the maintenance department and there is shortage and/or back order of the part to fix the problem.

This is now the second time this has happened on my brand new 2023 Jetta se. The vehicle only has 1831 miles on it. The fault happens when the car is being driven after approx. 15 minutes. Epc light, check engine light, and yellow warning light illuminate. Also sounds like a misfire when limping off the road. Codes read at dealer are p0304, p0363, p1d74, and p1d75. All of these codes relate to cylinder 4 misfire. Car is driven only at highway speeds, since it is a commuter car. This happened on 2/16/2024 and 2/22/2024. I attached pdfs of the service invoice from the first instance. I also attached a pdf of a NHTSA file containing a list of vw vehicles that are having the same issue, with the same engine.

When I started the car an alert came on the said the door there was a driver door contact switch error. When I was trying to back up the emergency brake came on. The door was closed. There was an electric parking break error. Also a start stop error. When trying to go forward the parking brake kept coming on. I was going 10 mph and the e brake engaged and would not let me out unless I turned off the car and turned it back on. When I brought it to the dealership they ran tests on it and they said it was the door wiring harness. There is problem with it and it is not safe to drive. When driving around corners it also has a tendency to want to depart you from the lane. It will try to kick you out of the lane even if you are in the middle of the lane. It has done this around corners and when driving straight. It caused my sister to be driven off the road. This has been brought to the dealerships attention and they found a problem with the lane departure and told me that they could fix it and then they came right back and told me that there was nothing wrong with the car.
