“I own a 2006 Chevrolet silverado truck. I have noticed a ticking wile the trucks engine is cold. I have taken in the truck for repair and my mechanic informed me that the exhaust bolts are broken on the exhaust manifold. This is a common problem with GM trucks and there should be a recall from GM to fix this problem.”

NHTSA complaint #10392034, filed 2011-03, 63,593 miles“2006 Chevrolet silverado. Blower motor resistor shorts out and melts wires, have replaced twice - once a burning smell was noticed. The same problem happened with an 04 and an 05 silverado at my job. Despite fire hazard, inability to use defrost causes visibility problems.”
NHTSA complaint #10312880, filed 2010-02, 50,500 miles“My 1500hd super crew cab has had a harmonic rumble since the second week of ownership. It varies some with speed and load but can be felt through the floor into your feet and be heard easily at all times. It gets progressively louder until it is serviced. The dealer has worked on the problem 4 times in 5 months and it still has the problem. It will go back for a 5th visit this week.”
