Lots of condensation in right headlight
The air bag light and sound indicator randomly and repeatedly alerts? Service air bag? Whether the car is in motion or stopped or has an adult passenger or does not have a passenger at all. Have taken the vehicle to the buick dealership on three occasions and they cannot find the problem or a recall. Issue has not been resolved.
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.
We had the driver's headlight replaced under warranty due to it holding water. Once we got the car back and drove it at night, it was apparent that the light pattern was not the same. See photo. We were not able to see the road on the left side since the beam was essentially pointed down so i took the vehicle back and they said that the headlight was a new design and that's how it looks but they claimed to have adjusted it again. That week we drove to orlando at night and almost every car in the opposite direction would either flash their lights at us or honk their horn. I did a static test and the ledt light was illuminating overhead road signs at a distance of 50ft so we were blinding oncoming drivers. I contacted buick corporate and they told me to take the vehicle back to the dealer a 4th time, once again i was told this is the new design but we will adjust it. As it stands right now, my left and right headlights are throwing 2 completely different light patterns, i still can't see the left side of the road and the high beams on the left side don't seem to illuminate anything at all. I'm a licensed engineer and accident re-constructionist that has subjected other vehicles to dot and sae headlight tests and these lights will not pass. It also causes undue stress on the the driver since the lighting pattern is no longer consistent across the front of the car. I would like some help in getting gm to acknowledge this issue and correct it since they are telling me that once my warranty expires in may, they are no longer responsible
