Adaptive Cruise Control problems of the 2025 Volkswagen Jetta

I am reporting a recurring safety defect involving the adaptive cruise control (acc) system in my 2025 Volkswagen Jetta. The acc system fails suddenly and without warning while driving, including during highway operation. This creates an immediate safety hazard, as the vehicle unexpectedly disengages speed control and forces abrupt driver intervention, increasing the risk of collision. The defect first occurred during the first week after I took delivery of the vehicle and has continued for over a year. The issue is completely unrelated to any accident; it existed before the accident, persisted during body shop repairs, and continues even after completing all repairs recommended by the dealership. I followed every diagnostic and repair instruction provided by the authorized Volkswagen dealership, but the defect has never been resolved. The acc failure occurs intermittently and unpredictably, including during normal highway driving. When the defect occurs, the vehicle displays an acc error and immediately disables the system, requiring sudden manual control. This behavior represents a serious safety risk, especially at higher speeds or in traffic. I have video and photo evidence documenting the defect occurring during real driving conditions. The dealership and Volkswagen customer care have been unable to diagnose or correct the issue, despite multiple attempts and extensive time spent on repairs. Based on the timeline and repeated failures, this appears to be a manufacturing defect affecting the acc or related electrical/sensor systems. Requested action I request that NHTSA investigate this issue as a potential safety defect affecting the 2025 Volkswagen Jetta. The defect is persistent, unrelated to any accident, and has not been resolved despite multiple repair attempts. Given the safety implications, I believe this issue warrants federal review and potential recall consideration.

This submission is an update to my previous NHTSA odi complaint #11761837. I am adding new documentation provided by the authorized repair facility, including service records, diagnostic notes, and repair details. These documents confirm that the same safety defect continues to occur despite following all repair instructions and completing the recommended work. Please attach these materials to my existing complaint and include them in the ongoing review of this unresolved safety issue.

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.

"my 2025 Volkswagen Jetta is subject to safety recall 26v185 (90z5). The vehicle's instrument cluster fails to display speed, rpm, and safety warnings upon startup, creating a severe safety hazard. I visited heritage Volkswagen catonsville on 04/07/26, and they officially documented that the 'repair not yet available. ' Volkswagen customer care has refused to open a repurchase case or provide a safe solution. I am unable to use the vehicle safely and I am requesting an immediate intervention to address this safety issue. ".

The car has a manual transmission. In all other vehicles I have driven with cruise control, when the clutch is depressed, the cruise completely disengages, same as a brake. When cruise control is engaged and the clutch is depressed, the cruise temporarily disengages and re-engages when put into a lower gear or the same gear. Very scary since a majority of the time, the driver is anticipating a slow down. If left out of gear for a period of time, the cruise will fully disengage. I can only guess someone copied programming for the manual transmission car from an automatic transmission car. I have reproduced this behavior multiple times. Seems unlikely to do in standard cruise control. Vw of America contacted and seemed unconcerned. Has not been brought to the dealer.
