Open the full vehicle complaint log (all categories)Persistent and Dangerous Malfunction of Blind Spot Monitoring and Rear Traffic Assist The safety features of Blind Spot Monitoring and Rear Traffic Assist, designed to enhance driving safety, have unfortunately been plagued by a persistent and alarming malfunction. Despite the dealership's diligent efforts to troubleshoot the issue, the sudden and unannounced shutdown of these critical systems continues to pose a significant hazard during driving. The erratic and unanticipated shutdowns of the Blind Spot Monitoring and Rear Traffic Assist systems create an extremely hazardous situation. These systems, essential for ensuring road safety, can cease to function without any prior warning. This sudden malfunction significantly increases the potential for accidents and poses a considerable threat to the well-being of both drivers and other road users. In an attempt to rectify this unsettling problem, the dealership has made efforts to identify the root cause. However, no fault codes have been detected, leaving the issue unresolved. This persistent malfunction continues to occur on a weekly basis, further exacerbating the gravity of the situation. The ongoing malfunction of Blind Spot Monitoring and Rear Traffic Assist systems not only undermines the trust drivers place in these safety features but also compromises the overall safety of the vehicle. The inability to identify the root cause of this issue hinders the dealership's ability to provide an effective solution, leaving drivers and passengers vulnerable to the potential dangers that may arise from their sudden and unpredictable failure. The recurring and unexpected shutdowns of Blind Spot Monitoring and Rear Traffic Assist systems represent a serious concern for drivers, as they compromise the safety of both the vehicle occupants and other road users.
Blind spot assist warning shows up from time to time even when there is no vehicle near me.
The blind spot warning of the car has again stopped working. I had a similar issue in 2020 and that was repaired by VW Dealer. This is again an issue and is a safety risk.
The automatic emergency braking activated and slammed on the brakes, for no apparent cause. There were no cars, people, animals around. And luckily, no car was behind mine. This has happened NUMEROUS times previously, especially when going through roundabouts and downhill. This issue needs to be addressed by VW. I have mentioned it to service at a VW dealer, and they just tell you to turn off the front brake assist, but that is not a solution. Plus, you would have to turn it off EVERY time you start your car.
The Blind Spot warning, forward collision warning and parking collision warning suddenly stopped working even though they showed that the features were enabled in the car's dashboard settings. Fortunately, I realized this and took it to the dealer for repairs.
The contact owns a 2018 Volkswagen Tiguan. The contact stated that while the cruise control was activated with a vehicle in the lane directly next to the vehicle or two lanes over, the Collision Avoidance System would determine that the vehicles were too close and the Crash Imminent Braking System would activate and stop the vehicle. The issue most recently occurred while driving 70 MPH causing the contact to aggressively depress the accelerator pedal. The contact took the vehicle to the dealer who informed him that there was no malfunction detected. The contact spoke to the manufacturer who informed him that the issue was known however, there was no recall on the VIN for the failure. The approximate failure mileage was 20,000.
This vehicle's forward collision warning system is inaccurate and dangerous. It is very prone to errant activation. At least once a month, the vehicle's collision system would detect objects that were not there (often, when there was no traffic and also no roadway barriers like guardrails). These activations would result in the vehicle slamming on it's breaks, which culminated in warped brakes and premature wear on the vehicle. It was also hazardous to any vehicles driving behind me, as well as occupants of the vehicle - due to sudden jarring. My local VW dealer acknowledged this is a common problem with no solution, and not worth doing diagnostics on.
