Radiator problems of the 2015 GMC Sierra 1500

Radiator forms stress cracks from constant thermostat cycling. The resulting cracks cause the radiator to leak. Gm has issued special coverages for certain models but doesn't acknowledge it is a very common problem on other models outside the coverage.

I took vehicle to dealer for test drive for trade in purposes and was informed that my radiator leaked and it was a problem with 2015 GMC sierra and needed replacing for $1400. There is a recall for same problem with 2014 year but not 2015 and this should be corrected because it is a known defect and consumer should not have to pay for defective part.

It has a problem with cycling of the thermostat that causes stress fractures on the radiator leading to coolant leaks. Attached are gm bulletins on the 2014 and 2015 models. As one can see they have provided special coverage. My radiator is leaking just like the service bulletin says. This needs to be recall.

This complaint is regarding excessive surface rust on not only the frame of my truck, but on critical engine component clamps in the engine bay. Any screw style hose clamp in my engine bay are rusted worse than my other 9 year old car with 102,000 miles on it. I wash my truck, including undercarriage, periodically throughout the winter to try and keep the salt off. My truck is a 2015 with 40,000 miles, and just recently, the rust had completely eaten through the lower radiator hose clamp causing all the engine coolant to leak out. I noticed the rest of the clamps within the engine bay to be in the same condition, along with the frame, and suspension components. It is clearly only a matter of time before they fail while I am driving, which could cause a failure of any system using one of these rusted clamps, such as the brake lines, power steering lines, oil lines, or transmission fluid lines.
