| I purchased a 2002 chevrolet silverado 1500 extended cab from my local dealer (register chervrolet, brooksville, fl) in october of 2003. when i purchased the vehicle i was pretty much led into buying the extended warranty for my truck which they said would cover anything that was to happen, all i would have to pay is my deductible. in june of 2004 after driving to ft. myers to visit friends, my engine stalled, lost oil pressure and the warning lights went off. not wanting to harm the engine i braked and turned the vehicle off. with me were witnesses; my mom who is a disabled, parapalygic, and my brother and sister. i called the chevrolet help line and they had no record of my warranty on file and were not willing to help me get a tow truck that should have been covered. i ended up having a friend call and get my vehicle towed through their aaa to my home. i finally arrived home at 1:30 am! the next day i had it towed to register chevrolet and they said they would look at it and let me know. rememeber, i was told that anything would be covered so i was at ease knowing it would be fixed and i wouldnt have a huge bill. boy was i wrong there. when they finally did get along to calling me they told me it would be $207. they said it wasnt a warranty item and so they would not reimburse me for towing as well as repairs! ok, all they did was re-route the ac run off, which because it was designed poorly had rotted the distributor cap. this is what i was told and it was written on the bill i got. if this has happened to me i am sure that it has happened to others, so i even if it was not covered by their warranty i do believe it should be a recall item. all i want is the difference back as well as the towing charges paid. i have all reciepts for this matter. thank you!*ak | |||

| 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. *nm | |||

| 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. | |||

| I too have the piston slap problem with my 2002 silverado hd 6.0l engine. i took it to the dealer at about 2400 miles and was handed a technical bulletin that was dated from 1999 (problem has been known since then) telling me that gm is working on a fix. they did want to look at the truck to make sure nothing else was wrong. there is no fix, just an extended warranty on the engine alone even though i already paid for the extended warranty for the entire vehicle. you cannot get the warranty agreement mailed to you to look it over, they will only send it if you agree to accept it over the phone. bought the truck in good faith and was sold a lemon. maybe if their profits were affected by a recall they might think twice about stealing and lying to consumers. *nlm | |||

| I have a 02 siverado a 5,000 miles the motor started knocking, the dealership said it's out of there hands, and told us to call chevrolet document #816465, which says the knocking is normal, and all they can do is extend the warranty. we all know this is not normal,go to www.bigclassaction.com and file a complaint. if we can get everyone together we can get a class action suit against them. we all have paid to much for our vehicles to letgm get by with this. lets stick together, tell every one. | |||

| Engine makes loud ticking noise when warm at idle. gm states normal condition. not all duramax deisels make this noise. it cannot be normal. gm has no interest in pursuing. although this may not be a safety issue, unless the engine explodes as a result, it still is very disheartening that gm will release the product with bugs and the customer is forced to accept.*ak | |||

| The engine keep crashing down, the indicator say low engine pressure, check engine pressure, then the hole truck will shut down in the middle of producing. this happen three time already. im on the highway driving 80mil and the truck will shut down, cant move the wheel, cant change lines, cant restart the truck or anything. this has almost coast me life three time. what kind of safety shut down is that. i think it is very unsafe and needs to change or fix. i spent over 2,500.00 on my truck thinking the problem is fix, but it keep recurring. the chevy engineers guys just say that the prob cant be fix and my best bet is to get a new truck, or engine. i don't have money for that. *tr | |||

| Dt: the contact stated the exhaust manifold warped and caused the studs to snap off. this could cause the exhaust to leak on a cold start. the vehicle was taken to the dealership, but has not yet been repaired. the contact's son-in-law discovered this problem after inspecting the vehicle because he had the same problem with his vehicle. he stated the original studs were too small, and the new studs were bigger.*ak left and right exhaust manifold bolts broke and were replaced. *ak | |||

| While driving under normal driving condition, no bump or obstacle on the road exhaust system separated and dropped, but stayed attached to its structure. the muffler dangled. the cause of the failure was unknown because the vehicle wasn't been inspected by a dealership nor mechanic. | |||
