Consumer Description

The Adaptive Cruise Control system (collectively including the Lane Departure Warning, Forward Collision Warning, Smart city brake support etc.) on this SUV stops working abruptly and randomly while the car is in operation on the road. This is a major safety concern as it can crash into a leading vehicle in absence of adaptive cruise capabilities. The system generally resets or starts working again after a 5-10 minutes, but there is no rhyme or reason why it stopped working or when it would start again. It has happened in cloudy, harsh cold weather, and also on a bright, warm sunny day. This makes the ACC unreliable. The dealer could not reproduce the malfunction, as generally the car is stationary in the workshop or isn’t driven for a long enough time while testing.
