Car was back in the shop for carburetion problems from the time it was new. Brakes are replaced with 50% + of pads left due to poor sensor system. Sunroof hoses pinched during assembly and as soon as a minor amount of dust collected in them water filled both front floor wells. Water ran down over fuse boxes while draining to the floor. Now the lights keep kicking out. Rear wells filled with water (behind access panels to rear light bulbs). All the wiring "boxes" filled with water and now all the junctions are corroded. Rear tail lights go out whenever they feel like it. This car is about the poorest engineered vehicle the devil could have designed. Need a Buick to get parts and make trips.
Start over and get away from all the fancy sensing devices since they are half the problem. Don't you understand basic water tightness and the need for dependability.
