Wiper problems of the 2007 Chevrolet Tahoe

Tl- the contact owns a 2007 Chevrolet Tahoe. The contact stated the dash is cracked above the passenger side air bag as well above the speedometer. The vehicle was taken to the dealer where it was diagnosed that it was a common problem with this model vehicle and gave a quote to repair the vehicle. The vehicle was not repaired. The manufacturer was made aware of the issue however the stated that they considered the failure as cosmetic. The vehicle failure mileage was 111,000. Kh.

Twice now while driving my wipers have quit on me. After first time it threw a "no start" code and the truck left me stranded. I have spoken with an agent with GMC and they suggested that I file a claim with you. It is very scary and I am loosing confidence in my truck. Luckily nothing serious has happened but it very well could. GMC does not have record of this issue with others but I would advise that it be looked into before my comments take a more serious direction. Please advise.

Rear defrost cable came off numerous times had dealer fix at least twice and then they replaced whole back glass then cable still continued to come off . It only came off during months defrost was being used, cold weather. Cable connection seemed to be melting off from solder. This too seems to be common among 2007 Chevrolet Tahoes. Also since owning this Tahoe the windshield wipers have never seemed to be wiping fast enough in a hard rain,( not a downpour, just steady heavy rain) it is very hard to see through windshield. With vehicles I have owned in the past, mostly Chevrolets, I have never had this problem.

Windshield wiper and solution comes on automatically even when the control is turned off. This occurs while driving making it hard to see the road with eccess solution is spraying continuously and uncontrollable.
