Volkswagen Jetta adaptive cruise problems

Filed Sep 21, 2026 · Driver assistance, Electrical · MS

The vehicle’s Forward Collision Avoidance system (Front Assist) and Automatic Emergency Braking (AEB) intermittently malfunction while driving. On at least three separate occasions during clear, dry weather with clean sensors, the AEB system engaged full hydraulic braking unexpectedly with no obstacles ahead—once while utilizing Adaptive Cruise Control and twice while driving manually. This severe "phantom braking" creates an immediate, life-threatening rear-end collision hazard on public roadways. Immediately following these braking events, the digital cluster displays the warning message "Front Assist Currently Unavailable."The vehicle has a documented history of electrical instability, including a prior dealership visit where technicians allegedly attempted to fix power errors by servicing a loose battery connection. However, electrical faults have persisted, culminating in instant, false "Engine is overheated. Safely stop the vehicle!" warnings within seconds of starting a cold engine, as well as non-functional rear seat heaters. These combined electrical faults align with an open powertrain ground failure, as described in the federal safety agency Recall 26V138 / VW Campaign 97TC (loose transmission ground wire causing stray current backfeed through sensor harnesses). The vehicle was towed to an authorized Volkswagen dealership on 09/14/2026 after displaying an instant cold overheating error and remains there for diagnostic inspection. The vehicle and its components remain intact and are available for inspection upon request.

When driving using cruise control, the vehicle will alarm if the driver is not holding the steering. If the driver does not take control of the steering wheel, a secondary alarm will alert the driver on the dashboard to take over steering. If the driver does not take over steering, the vehicle will aggressively pulse the brakes to alert the driver. In this vehicle, the alarm may trigger when holding the steering wheel from the side or bottom, and it generally occurs on straight or minimally curving highways. If music is turned loud, it is difficult to hear the secondary alarm and the vehicle may unexpectedly and aggressively brake even when the driver has full control of the steering wheel. To cancel the alarm may require significant input or even steering out of the lane. In wet conditions, the automatic pulsing of the brakes may cause loss of traction and total loss of vehicle control.

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 the federal safety agency 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.

My 2022 Volkswagen Jetta (purchased new) has a recurring Travel Assist/Adaptive Cruise Control safety malfunction that has existed since before approximately 24,000 miles. While driving with Adaptive Cruise Control or Travel Assist engaged, the vehicle repeatedly warns me to "Take Control of the Vehicle" or indicates my hands are not on the steering wheel even though both hands are firmly on the wheel. I often have to immediately tighten my grip to prevent the system from escalating. On numerous occasions, the vehicle has also applied the brakes unexpectedly at highway speeds when there was no apparent hazard in front of the vehicle. These unexpected braking events create a serious safety concern, especially in traffic. I drive between [XXX] and [XXX] approximately twice each month. During a typical one-way trip, the steering wheel recognition warnings may occur a dozen or more times while using Travel Assist or Adaptive Cruise Control. Unexpected braking has occurred repeatedly over the course of ownership. The vehicle has been taken to an authorized Volkswagen dealer multiple times for this same issue. Volkswagen has replaced the steering wheel multiple times, updated software, opened a Technical Assistance Center (TAC) case, and at least one technician duplicated the concern during a test drive. Despite these repeated repair attempts, the problem continues. I am reporting this because I believe the recurring Travel Assist failures and unexpected braking present an ongoing motor vehicle safety defect. Below it asks for the approximate date the incident occurred. It started approximately in XXX but it happens all of the time still.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle experienced a failure related to the steering wheel assembly that caused the "Travel Assist Not Currently Available" warning to appear while driving. The issue affected the operation of the vehicle's driver assistance systems, including Adaptive Cruise Control and Travel Assist functions. An authorized Volkswagen dealership diagnosed the vehicle and confirmed that the steering wheel assembly requires replacement. The vehicle is currently available for inspection. 2. How was your safety or the safety of others put at risk? The failure caused the vehicle's driver assistance and safety systems to become unavailable while the vehicle was being operated on public roadways. The unexpected loss of Adaptive Cruise Control and Travel Assist functionality could increase driver workload and create a potential safety risk, particularly during highway driving where these systems are designed to assist with vehicle control and spacing from other traffic. 3.

Adaptive Cruise control stops working suddenly with message "Travel Assist currently not available". Warning goes after restart or have to go and cancel assist completely and start again and then it works for few minutes and appears again. The problem sometimes doesn’t show up for days but sometimes shows many times within hours. Happens usually on long drives. Once it occurs, it happens multiple times if I try to reset within the drive. It gets disabled sometimes on high-speed free ways and adaptive braking suddenly goes away in middle of on ongoing braking or sometimes car suddenly starts slowing down on high speed. Happening for 18 months now. Previous dealership said we could not replicate the issue and did not provide any fix. Same goes for Front Collision Avoidance Warning, it beeps loudly up randomly with no obstacles in sight . When complained this to dealership during first service, they said it could be dust but i still have this issue ongoing intermittently showing up with no fix from dealership.

I was going down the highway and enable cruise control, the car fell like RPM dropped then suddenly jolted back. Also when driving it feels like the transmission isnt proper and yoy can feel it be shotty. I've asked the dealer and they said "this is normal the camera may see a bump and cause it to slow down" but this has happened without the ACC and on normal cruise control mode. I think this can pose a saftey risk as this could cause further transmission and or engine damage and cause a failure in highways leading to a risk.

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.
