2002 Chevrolet Silverado: engine knocking or ticking

Filed Jul 23, 2013 · Brakes · 86,638 miles · OH

I started my truck in order to put it away in the garage, and the brake pedal went to the floor. Upon investigation, I found a pool of brake fluid below the truck. I also saw that all of the brake lines were extremely corroded and needed to be replaced. I went to my local dealership to inquire about repair costs, and was told that repairs would be over $1,000.00. I have never seen corrosion like this in any vehicle that was less that 25 years old. I have restored many vintage cars, and have never had to replace a steel brake line due to corrosion. I had my two young grandsons and my wife in this truck with me less than a week ago, and if this brake failure had occurred while we were traveling on the interstate highway, it is likely that we all would have been killed. These vehicles are ticking time bombs, and must be taken off of the roads. I have garaged this truck since I purchased it as a new vehicle, and it has been serviced at our local chevrolet dealership per the manufacturer's schedule. The corrosion issue is not due to neglect, but rather to the use of substandard material. This is an urgent issue that must be addressed and rectified.

Dt*: the contact stated the ABS engages at low speeds of 20 MPH and below. As a result, the stopping distance was increased. There is a the federal safety agency recall, # 05v379000, regarding the ABS. The vehicle has the same problems as indicated in the recall; however it is not included in the recall because of the VIN. The vehicle was taken to the dealer for inspection. The dealer cleaned the wheel speed sensor, replaced the pads and rotors. However, those replacements did not correct the problem. Additionally, a knocking noise was heard in the engine. The dealer inspected the engine although, no repairs were made. The passenger sie window was inoperative. Updated 03/28/06.

Cold engine start-up knock. I own a 2002 silverado z71 with the 4.8 engine. The engine has had cold start-up knock since I have owned it. I have asked dealers about it and have been told it is normal. I build engines for and own to drag cars. One is an et footbrake car with a mild 350 ci small block chevy. The other is a 48 fiat altered with a 434 ci small block chevy stroker. Both have forged pistons and neither has the cold piston noise that this bone stock 4.8 has. I currently have 39,139 miles on my truck and want it to last as long as possible. Under the current circumstances, I don't think it will last much longer before it cracks a piston skirt or severely damages the cylinder walls. It is my intention to contact chevrolet in the next couple of days but after reading the complaints on this site, I am prepared to be told the same as the dealer told me. I am also looking into the class action suit approach to get a remedie to the problem. Another issue is the brakes. The truck has 4 wheel disk and stops like it has four wheel drums without power?? I owned a 97 sivlverado that had brakes that worked the same. You would think that a truck that cost 30,000 dollars would be a little better constructed.

Knock in motor of 2002 chevy silverado, 5.3 motor with 30,000 miles. Dealer says knock is normal. Chevrolet sent letter to me stating they will provide service coverage for engine till 100,000 miles, but knock is normal. They claim that this is full coverage parts and labor but won't send letter stating full coverage only that they are pleased to provide coverage. Sounds fishy! The knock continues to last longer on cold start and gets louder by the week.

Engine knock.. Hot & cold. Sounds like lifter noise, gm says it's "normal" . Over 30 years as a mechanic, I know there's no such thing as a normal knock. After researching this issue, I find there are about 800,000 vehicle involved. Gm needs to fix these vehicles. Gm service bulletins refer to this as piston slap. Any slap, scuff, or abnormal noise in a cylinder is detrimental to the metals.

The duramax diesel engine has a loud ticking noise. Bulletin #02-06-01-022a says that all the engines have it, but that it can't be heard in some. Gm's attitude is "live with it!!!", we are not fixing it.*ak a a

2002 chevy silverado with a 4.8l engine knock, from what gm said is piston slap. They said they will not fix this problem at this time. They said they send out a letter of warranty for six years or 100,000 miles, if engine fails due to the piston slap/knock. I think that something needs to be done about this. There could be a safety issue with this, such as engine failure on the interstate. We the consumer should not be told to deal with it, when paying up to 30,000 dollars for a new vehicle, that has a piston knock. This needs to be fixed, not covered up.
