I got this truck used at 94K miles on it. It was still in standard warranty. I got the oil changed started getting that clicking/knocking noise. I took it back to the shop that did the oil changed. They looked into and told me it was a common problem with Chevy engines is the valve lifters break and needs replaced along with the cams. If I drive too much a possibility to add shavings into the motor and tear it up. Quotes from 3 different friend recommend auto shops from all of them to get a new engine or get rid of the truck. I am still making payments on it. So can't do that. I did take it to the dealership and they refused to help me at all. I was out of the warranty period and good luck. That sucks! I did make a scene to them in front of customers. Since then I have done some research finding out this is very much a problem in all Chevy engines dating back to 06. The afm, excessive oil consumption. At one point Chevy did do a recall for a year in 07-08. For this problem. But not for any other years I can find. If they knew/know of this problem why not solve it? I have to fix this truck its my daily driver and work vehicle. Total hating Chevy right now and has always been my love! I am a single mom and I know have to come up with a new engine about 3,500 then add labor and supplies about 6K total. Not have and very stressed out.

Well maintained vehicle with less that 78K miles and transmission failing. GM should be forced to step up and pay for the repairs. Vehicle is a lemon. Have replaced and fixed multiple other issues. 3 door lock actuators gone out...2 times fixed fuel system vapor canister...passenger window switch failed...cruise not working...

Truck comes to scretching haltwith motor running but wont go, door locks and all gagues going up and down a 100 mile an hour. Sometimes everything dead and all of a sudden it comes back on. Air comes and goes. All lights flash. Those uprandom codes. No warning its going to happen. Radio will start playing very load cant shut off. When it does this it sometimes lunges forward aboit twenty feet and may run fine or do it again. Went to dealer truck stayed 2 months. Said they fixed. Few months later started again, next dealer said they couldnt find anything. Contacted GM on both incidents. Nothing happened.
