2018 Volkswagen Tiguan driver assistance problems

Filed Aug 25, 2026 · Driver assistance, Electrical · WI

I purchased this 2018 Volkswagen Tiguan in September 2019 and began noticing an intermittent rearview-camera problem around that time. I do not remember the exact date of the first occurrence because the problem initially happened only occasionally and was not persistent. When the vehicle is placed in reverse, the rearview camera intermittently fails to provide a reliable image. At other times, it operates normally. Because the problem is intermittent, it has been difficult for the dealership to reproduce consistently. Loss of the camera image reduces visibility behind the vehicle and creates a safety concern while backing up. An authorized Volkswagen dealership inspected the vehicle. The service manager stated that the stored fault indicates an intermittent open circuit in the video cable. The dealer’s diagnostic history reportedly shows approximately 90 fault occurrences beginning July 19, 2026. During recent testing, the dealership was able to get the fault to set once. The dealership has not conclusively confirmed that the camera control module failed. It proposes replacing the module as the first repair step for approximately $1,165 and stated that additional repairs may be necessary if the module replacement does not correct the problem. Volkswagen Customer CARE documented the concern under Case Number 07696586. I am submitting this report because the intermittent loss of the rearview-camera image may reduce the driver’s view behind the vehicle and increase the risk of a backing collision.

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!

On September 19th 2025, while driving on the highway at normal speed, the instrument cluster fuel gauge misread the fuel level and indicated that the tank still had fuel. Without any warning light or low-fuel alert, the vehicle suddenly lost power because it was actually out of gas. I was traveling with my boyfriend and our three dogs. We became stranded on the shoulder of a busy highway as vehicles passed at 70–80 mph. The outside temperature was about 85-90 at the time. This created a serious safety hazard: The cluster’s inaccurate fuel reading prevented me from knowing we were nearly empty. The engine shut down unexpectedly, leaving limited steering and braking control as we coasted to the shoulder. We were exposed to high-speed traffic and extreme heat while waiting for assistance. Additional cluster/safety issues observed: No audible turn-signal “click” or indicator sound when using the blinker. No warning chime if the car is left running when the driver exits (for example, if the ignition is on but the door is opened or the key is removed). The vehicle is out of warranty, but the dealership diagnosed a failed instrument cluster and quoted about $2,500 for replacement. Why This Is a Safety Concern: The instrument cluster provides critical driver alerts. Inaccurate fuel readings, lack of turn-signal audio, and the absence of an engine-on warning chime all reduce driver awareness and can directly lead to dangerous situations on the road. Requested Action: I urge the federal safety agency to investigate whether the 2018 Volkswagen Tiguan’s instrument cluster/fuel-level system and related warning features contain a design or manufacturing defect and to consider a recall or other remedy to prevent accidents or injuries.

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.

My vehicle has had repeated issues with passenger airbags, after last repair all of the safety sensors failed and received warning on dashboard (no collision protection, no Adaptive cruise control) after bringing back to dealer car was returned to me and told the parts are unavailable. Currently I have had a vehicle under warranty which has no collision protection features that came with the car. Car by dealer’s own statement it is unsafe to drive yet was returned to us. It has been nearly 3 months and are continually told that there is no fix in site.

Engine keeps failing and dings while driving non-stop. Causes the vehicle to think there is another vehicle near me and activates the emergency braking in the middle of the highway almost causing me to crash. I have taken the vehicle to dealer and told it is fixed about 8 times now

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.
