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 NHTSA 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.

3 Warnings problem

Failure Date: 11/30/2020

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.

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.
