Blind Spot Detection problems of the 2018 Volkswagen Tiguan

A few weeks ago I noticed that a car passed me and the little blind spot alert light didn't light up. When I arrived at my destination I did some scanning through the menus and I discovered that the blind spot (side assist) was not on, but when I attempted to turn it on, the car said "function not available". After some investigation (using a odbeleven scanner) I discovered that the blind spot assist functionality has a fault with "no communication". This system, upon failure, give no indication anywhere, plus this also means my rear back up alert ( a kid running behind my car, for example, which would normally cause a huge alert, nothing happens). I also learned that there is a technical bulletin : [xxx] related to this. This should be a recall, its dangerous to have no indication that a safety feature system like this is completely nonfunctional (without an odbeleven read). A light on the dash should alert me, or a message on the screen. This is just plain dangerous! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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 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.
