Dash cracked from corner of passenger side defrost vent to airbag, and again from the defrost vent to over dome over driver cluster and any thing wet can get into components of the speedometer and rest of stuff in there. Trucks never been kept in sun, and had one dealership already confirmed that its a defect in product not caused by elements or lack of care, or anything done to it. Its parked most times and it's getting worse, im handicapped and vehicle only used when im driving or in it. I'm not happy about this bc it's not like this was a cheap vehicle and im on fixed income, and paid cash and extended warranty will not cover cosmetic. Its almost splitting at top now on driver side to go around the front of dash. Also had to replace battery and alternater only at 50K miles and warning light never came on, noticed dimming of lights when applying brake pedal and while driving the voltage gauge kept going to 0 and back to 14 back and forth, got to dealer and again tried sending me home but finally tested original altenater and it wasn't working so replaced and cost me $100 but still no warning or engine light and then dealer had to tow my vehicle again bc system no updated found problem by another dealer, under coating coming off and rust on top by rack on roof on each side. This was a $68K vehicle and because of defects and not a recall we're responsible for half cost, dealers want over $500 for something that is a design or product of poor quality, this is how Chevy/ GM buyers are treated when buying one of the top luxury vehicles. What company does this, I paid cash for this dream vehicle and the product is all over internet and lawsuits bc of product defect, cheap products used but sold as top of line. Wow.

Electrical system cutting out while driving the vehicle. Full reset of the electrical system during driving conditions. Brakes unresponsive, steering, engine, dash and all other electrical equipment. Vehicle was sold to us through ron cater in alvin, tx with an open recall and not repaired before being driven off the lot. Will be taking it in asap.

The HVAC actuators of all sides are very regularly damaged and must be recalled, even newer version like 2012 are facing such issues.

While driving approximately 70 mph. Vehicles engine and instrument panel cycled on and off randomly. Noting that once I was able to pull off the road and come to a complete stop the vehicle finally shutdown. Furthermore attempting to turn the truck on only resulted in flickering electronic equipment with no response from the engine. Two weeks following this event fortunately enough after the vehicle was parked we noticed that electric folding mirrors weren't responding to the push button actuating the folding mirrors feature. This event we were able to get on our camera phone. Same flickering of electronics and again the engine didn't respond, turn over. In both occasion it was only after sitting approximately 30min. That vehicle finally responded and turned on.
