2001 Chevrolet Suburban: engine knocking or ticking

Filed Aug 21, 2013 · Electrical · 104,500 miles · CA

My vehicle's "service engine soon" light continues to light up even after having the code erased. Many other owners of chevrolet suburbans have the same issue. Obd code p0332 states the knock sensor has low voltage. The problem many people have is when water or moisture gets into the engine compartment water begins to pool over the sensor and seep into the sensors. The lacking of water seal in this pooling area damages the sensors. The vehicle thus cannot pass it's bi-yearly smog test and also creates a false sense of vehicle reliability. If other issues come up other than the bad sensors the driver would never know.

My 2001 chevy suburban 2500 lt has 52000 miles it is burning oil on long trips. It has been in the shop four times for this. Chevy does not want to pay for this problem because it is not a recall as of now. They want my private warranty to pay for this. I also have a fifty dollar deductible that I must pay. There is a tsb on this which I have a copy of. I also think the engine sounds like it has a slight knock. I was told there is a recall on the brakes for rust corrosion which it has been two weeks and I have not received my recall. I am afraid to drive this car. About four months ago, I was driving this vehicle and it would just die. I would lose all power . It was very hard to steer it to the side of the road. Luckily I never had anyone behind me or they would have slammed into me. It was in the shop for this twice. The first time they said it was probably the oil filter so I picked it up and it did it again. I told the service manager I was afraid to drive this truck and if something happens to my family I would sue them well the second time they found the problem it was something with the fuel injector. I am very dissatisfied with this truck and I also feel chevy is not backing their truck.

There was an engine knocking problem. The dealer and the manufacturer were contacted. The consumer was given a letter that certified that the manufacturer was aware of this problem, and the vehicle was okay to drive. The consumer disagreed, and felt the vehicle was not safe. *ak there was a noise, rubbing sound when the brakes were applied. There were knocks during the initial start of the day, and the window was noisy while operating as the regulator cable was loose. *scc

We bought a 2001 chevy suburban , brand new. Since we owned it, the air conditioner motor failed the first month, front left shock pops when turning, driver's seat warmer doesn't work (possible faulty switch), the 5.3 liter engine knocks and pings like crazy even when using 93 octane fuel on a steady basis. The front passenger seat was found to have cracked seat rails but dealer had no replacement rails, have to order them. Gas gauge doesn't read right (when on the red line it still has 6 gallons in the tank or 20% fuel left) the thing is a piece of crap! Gm didn't give a darn either. If you call to complain you get the run around. This is their top of the line passenger truck (suburban lt) and definitely not something they should be proud of. I definitely will not buy another, my parents just bought a new ford expedition since they saw all the crap breaking on this thing. Other friends have also not gm after seeing first hand my brand new lemon. Another friend of mine is on his 3rd replacement motor for his camaro window. He bought AC delco motors each time and they all stopped working within one year. All of these products, including my suburban are being made in mexico I just found out. I think that they must have a big problem with quality control down there or their sampling size is nil. Well I hope gm has made a bundle of profits off nafta because they've definitely lost at least 7 sales that I know of due to my $40,000 piece of crap. I wouldn't recommend this car to anyone. I have heard of others complaining of the same pings/knocks in their 5.3 liter gm engines. Does anyone know of a class action lawsuit regarding this? Oh and the emergency brake is way too loose.
