Vehicle cannot be driven. I will turn the car on and there will be no heat, Then the next time no headlights. All fuses and relays checked. Sometimes if I wiggle the fuse box the windshield wipers will start working.

When the weather is cold the speedometer will not work. Head's up indicator does tell the correct speed. This summer the temperature gauge went past hot and is stuck pointing to the bottom of the gauge. A month ago, and the most irritating the gas gauge failed to register. It also points to the bottom of the gauge. I have owned Buicks for the past 30 plus years never have I experienced non working gauges. GM needs to offer a definite fix for these failures.

I have fixed and fixed on this SUV. The RPM and the Speedometer are not working. At stopped the Speedometer is showing I am going about 150. the rpm gauge is all was at 0 the gas gauge works sometime and sometimes the coolant gauge works.. Who knows. GM needs to recall this car... I have always driven a GM. Both my parents worked for GM.. I will not be getting another one...
