Recently replaced o2 Sensor and cleared check engine status. I failed the state emissions test because the Cat indicates inc or not ready, (catalytic converter). The procedure to clear this condition is dangerous and unreasonable. It calls for accelerating to 55MPH or higher for 2-3 minutes then decelerating to 20 MPH, not using brakes, and travel for 2 minutes then accelerating back to 55MPH, repeating this process up to 5 cycles to clear the CAT status. Given the drive speed this procedure would have to be done on a highway and could very likely cause a collision. This is very hazardous and should not be a requirement to complete vehicle inspection.

I went to a guys house who was selling a 2005 Chevy Silverado with 114,000 miles on the cluster. He didn't have the title under his name. He was title skipping. Gave him $5,000 that he was asking for on 11/02/2020 then went to find the owner with his name on title. Had him sign the title over to me. Went to dmv and changed the title under my name. Then 11/28/2020 I ran a carfax report to see what maintenance has been done on my truck and it says that my truck had more than 250,000 miles on it. I confront the man that same day. And asked him if he changed the mileage he said yes. I then asked him to give $2,000 because the truck is not worth $5,000 he said he was not going to give me a penny. So I made a police report that same day on 11/28/2020

The vehicle was not diagnosed by a dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 152,000.

When I purchased my truck the dealership promised to have it fixed, I then went to the nc dmv who handles vehicle. I had been receiving the runaround from everyone. I am sure it has been in a flood that I was not informed about due to all the rust underneath the vehicle. When I purchased it was stationary at a private dealership in a city next to a highway.

Like so many others, I started to hear a ticking at startup and sometime an exhaust smell in the cab. I found 2 exhaust manifold bolts broken on each side. It can get bad enough to open a window at times. Dealer said it's a common problem. There should be a recall on a emissions and safety issue. I take very good care of my truck and this should not happen. I see it has been a problem since 1999.what can we do to get reimbursed for the cost of repair" if I have an independent repair would GM ever cover it or does it have to be done by a high cost dealership? they got VW for emissions what about GM"

Drove into the garage and parked. A loud explosive noise came from the truck and fumes began funneling through the hood of truck. Quickly turned off ignition and got out of vehicle. In a few minutes garage was full of intense flames. The heat was so intense it blew open the door into the house and burned/melted the laundry equipment and three rooms, and the second car in the garage, sending smoke damage throughout the entire house. Vehicles melted and everything in them and in the garage- mower, snow blower, small equipment and more, was totally destroyed. The firefighters were able to contain the fire to areas identified above. There was extreme smoke damage throughout the entire house.

I went to start my truck in morning to get to work and this loud ticking noise from under the hood, I shut engine off panicking and opened the hood. Went back and started truck again and looked around, I didn't see anything but heard it. Checked oil since it sounded like the lifters but had plenty of oil. Stopped on way to work and got some slick50 supercharge engine treatment. At breaktime checked oil again and added the slick50, started engine and had lifter noise again but quieted down within 30 secs. At the end of my work day started it up and again lifter noise but quieted down again within 30 sec. Broken exhaust manifold bolts were found.

Cracked cylinder head and engine. This allows antifreeze coolant to mix in with the oil in the engine and goes through the exhaust, this also gums up the oil parts in the engine and requires new cylinder heads to be installed or engine replaced. I just recently was made aware that the General Motors is aware of this problem with there engines. And also was made aware that the General Motors has since fixed this problem after 2007, because this is not a problem that could cause death it is not listed as a recall. This problem is not made aware to the consumer but is published in technical service bulletins. This is known problem by General Motors. It is going to cost between $2500 to $5000 to repair.

The low coolant light went on. The only way to fill the system is to open the reservoir cap. Unfortunately because the engine had a head gasket failure the cooling system would not depressurize, even when cold. It seems to me that there should be a pressure cap that when the engine overheats it allows the cooling system to depressurize. This closed system is very dangerous especially when someone who is used to filling the overflow tank when the coolant is low. Because the lack of an over flow tank anyone that opens the plastic reservoir could became burned.

Truck has an exhaust leak at manifolds. 4 bolts have broken off of the manifold. My mechanic said this is very common with this truck and could cost up to and over $1,000 to fix. Check engine light is on so unless I fix it I can't go to state inspection. Also the brake lines are corroded and also need to be replaced. These are all defects not maintenance issues. www.youtube.com/watch?V=0yg6wlbnzgi it explains the problem better.
