What owners say
Brakes make a noise when I brake. I am only going about 25 miles and press on brake the brakes don't seem to stop right. There's a ticking noise coming from the engine or brakes.
Ok my issues is the same recall on many other 2017 gmc 2500HD but not my VIN. Recall number N172120230 (rear wheel hub but loose). In my situation I was driving at low speed went to stop and abs light came on from oil on my rotator, I also heard a knock from the rear wheel. I pulled over and looked under the truck to find my axel seal leaking fluid all over my tire and breaks. I looked into the Facebook form on this problem and found many people with the same issue. Had the truck towed to the dealer where the are refusing to repair and not coving under warranty for 1” bigger tires. My truck only has 39,000 miles and a axel seal should not be going out, and if so should be covered

Duramax ticking noise. Consistent tempo ticking noise coming from engine bay. Audible only when moving at low speeds due to increased vehicle/road noise at higher speeds. Not consistent with RPM or speed. No warning lights or symptoms at this time. Dealer says not common, but appears common on the internet. Cannot find source of noise. Truck has 18k miles.
Left and right sides rear exhaust manifold bolts broken off. It leaks exhaust, may be a fire hazard and could cause emissions failure and emissions components failures. This problem is on a 2004 gmc 6.0 engine. Noticed ticking noise at about 38000 miles and it would go away after 30-45 seconds. A gm rep said it was most likely the skirt less pistons and not to worry. Had some work done at a garage about a week ago and mechanic pointed out the broken bolts.
2002 gmc sierra 2500hd 6.0l 4x4. The 6.0l engine is knocking constantly, and from doing some research. This is a very common issue and needs to be resolved. Dealer said it is normal! Since when is an engine knocking, normal?
