We have classified the 2 complaints from 2015 Buick Enclave about EXTERIOR LIGHTING into the following categories.
Service side detection system . side and rear alerts do not work. notice comes up on dashboard every time i start the car. happened 200 miles after warranty is over at 50,000 miles.
Battery has been replaced twice in 20 months due to failure of charging system to recharge battery. turn signals do not work properly or at all. dealer says battery is "defective". low engine rpm to increase fuel mileage and automatic illumination of driving lights end up to battery being in a constant discharge state leading to failure. signal lights will slow down or stop altogether while sitting at a stop light. the vehicle has left me stranded several time because it will not restart - there is no warning that failure is imminent. poor design in one safety feature leads to a failure of another safety feature and eventually to failure of the vehicle altogether. there is no volt meter and no warning lights are ever illuminated.
