I noticed lately my car has trouble starting, especially after I get gas. Anywhere I take it, no one knows what it is. Literally someone said that I’m not holding the brake down when I’m starting it. I KNOW HOW TO START MY VEHICLE! It doesn’t want to start and sounds like a broke down Saturn when I start it. It takes like 20-30 seconds to start. ALSO that AC went out, I paid $700 AT Chevy, and then the AC went out again a few months later, again no one knows why. WTF!

Ii purchased the car new. at 3 years and 3 months the evaporator core failed dumping the Freon. I realize you stated the A/C is not a safety item but I read many complaint on this vehicle on the internet. I am a retired mechanic and the failure rate for evaporators is very low. I changed out maybe 10 in 30 years working on vehicles. This needs to be looked into and addressed by GM and corrected. Any help would be greatly appreciated.

I have a 2018 Chevrolet Premier Impala that has started skipping gears at 1st and 2nd while driving. The vehicle shudders when it changes gears. Took vehicle to dealer who informed me that the transmission needs to be replaced already. I haven't received any dash messages or vehicle warnings prior to noticing the transmission problem. I always kept the car properly serviced by the dealer for all routine maintenance requirements. I am the original owner of this vehicle. The car has under 100,000 miles. Dealer informs me that it will take at least a week before they can possibly get new transmission for vehicle. I may be without vehicle for at least 2 weeks minimum.
the vehicle had a sudden loss of power steering. No warnings or indications of any isues just immediate loss of the ability to steer

I PURCHASED THIS VEHICLE 2 WEEKS AGO NEVER BEEN HAPPIER. MY COMPLAINT IS ABOUT MY HEADLIGHTS THEY HAVE SERIOUS CONDENSATION IN BOTH AND THERE IS ABOUT AN INCH OR 2 OF WATER INSIDE THE HEADLIGHTS. THIS ISSUE IS CAUSING BAD VISIBILITY WITH LOW LIGHTING. I HAVE TRIED EVERYTHING TO KEEP THE WATER OUT AND PROVIDE HEADLIGHTS WITH PROPER AIR SO THIS DOESN'T HAPPEN. HOW COME CHEVROLET DIDN'T RECALL THESE HEADLIGHTS DUE TO POOR DESIGN AND IMPROPER VENTILATION. WHAT CAN I DO BESIDES SPEND $200.00 ON 2 NEW ONES?
GETTING A SECOND LOOK AT AIR CONDITIONING. I WAS TOLD THE COMPRESSOR COULD BE LEAKING AS THERE HAS BEEN NO FREON FOR OVER A MONTH OR TWO. THE FREON IS 120/POUND AND COULD COST 1000, HE MENTIONED FOR FREON ALONE. THIS IS A 2018, PURCHASED LAST YEAR AND I'M DEALING WITH A COMPRESSOR ISSUE AS WELL AS VERY EXPENSIVE FREON?
