Problems with 2002 GMC Envoy ENGINE AND ENGINE COOLING

Engine stalls, causing consumer to wait a half an hour to start vehicle again. this has happened three times. dealer has inspected vehicle and could not duplicate or correct the problem. please provide further information. also, abs failure. *ak

this is my second letter to your company gmc. plain and simple all i am looking for is the value of my investment. i have no desire to get anything free nor am i just trying to get a new vehicle. the 2002 envoy i purchased from you a year and a half ago would be fine if i did not have so many problems with it. about a month ago it had to have a new motor and this past week it had to go back to the shop to have a fan replaced at a cost of $800. i expect that next month i will be paying $500 plus dollars for some other repair. i knew that once this repair was done to the most important system of the vehicle i would have major problems for as long as i have this envoy. i am not going to allow this company to keep me in this situation. this is my final attempt to reason with gmc to work out some way for me to get a dependable vehicle that affords me the years of service any reasonable person would expect for a 30k investment. my gmc sr # is 1-5521-9927. i am quite aware of your assertion that you replaced the engine out of warranty free of charge. i would counter that claim by saying that the problems with the engine started long before the warranty expired. i have the service contract to show this. my point is i am still stuck with a 2002 gmc truck that has suffered a major engine failure and all the problems that come with that failure and this is just 2003. i would also say that the very fact that the engine failed so soon does not speak well of this vehicle or your company. i hope this is not the standard you have established for your vehicle. now only a few weeks after the engine is replaced i am faced with the truck going back to the shop for a major repair. i still have not mentioned the other problems i have had with the envoy. letters to the better business bureau,and consumer protection agency will also ...

We experienced, like a lot of people who posted complaints with nhtsa about engine failure in envoys that are not even year old or over 10,000 miles. we had an experience with our 2002 envoy where on thurs. 12/19 my husband was accelerating off of a take off ramp onto the beltway and all of a sudden he heard a loud clattering noise. he pulled over to the shoulder and could not go any further. we had it towed to the gmc dealer and they determined that there was a drive train failure with pieces found down to the six cyclinder head. they are replacing the engine with an "updated" engine, which means to me that there was a problem with the first run engines. according to complaints posted to your website this has happened to lots of people. when is the recall coming? stopping abruptly in the middle of the highway is very dangerous. does it take someone to get killed before a recall can be done? we are in negotiations with gmc at this time. i would like a response to my e-mail.

Engine died at high speed on highway, fortunately no accident. engine had to be replaced by gm due to defective manufacture, piston ring slipped and damaged drive shaft. extremely frustrating experience dealing with gm.

Engine stalls for no apparent reason. i have contacted dealership and they can find nothing wrong. i advised them of a recall regarding the fuel system that may affected the problem. says they replaced the fuel filter. the first time i took it in, they said that it was the ignition switch. also transmission makes a very loud noise when attempting to take off at times. it sounds like an engine fan that will not go off. there is a major lost of power when this problem is occuring. i bought this car as a program car, with @ 11, 000 miles on it already. i've had problems with it from day one. i have only had it a few months. i am extremely irritated with this engine problem. this is extremely unsafe. dt

When vehicle is at a complete stop or idling engine will die out. the dealership reprogrammed the main computer chip, but the problem recurred. they the replaced the chip. please provide more details.

Upon being inspected at the nearest local dealership, the #6 piston was found to have "splintered" a half moon piece off the top of the piston head. this in turn "popped" the cylinder sleeve retaining ring from the top of the cylinder when the piston came up. with the ring removed, the cylinder sleeve also rose outside of the cylinder wall and was caught by the piston on the downward travel. the complete engine was replaced. vehicle was in the shop for 20 days. the dealer's shop foreman checked the records and found that 150 other engines will be directly affected with a possible 180 probably affected.*ak

2002 gmc envoy engine stalls while stopped at traffic light. sometimes a near-stall condition occurs whereby the engine idle dips really low, engine shudders, then idle recovers. this usually happens just before or after the air compressor for the rear suspension inflates. so far the pcm, throttle body, and ignition switch have been replaced. dealer is currently making 4th attempt to fix problem. problem has been occurring since 8/2002.

Vehicle stalled in stop and go traffic. vehicle at dealership at this time.*ak *slc

Transmission does not seem to downshift; loud fan noise with loss of power; hard shift into gear from start; missing rear seat latch to hold down seat and easily wobbles when shaken; hook for latch is present but no latch present seems to be design flaw. *ak

Engine dies with no notice at highway speeds (twice within 500 miles). *ak

Vehicle has stalled in traffic five times while traveling between 55 and 60 mph. dealership has examined vehicle, and could not reproduce the problem. *ak vehicle also stalled once while at idle and in park. dealership has replaced computer with no significant improvement, vehicle has been seen by dealer six times. nlm

Service engine light illuminates, engine cooling fan engages, engine power greatly reduces and transmission shifts improperly. loud noise from computer controlled engine cooling fan. vehicle will not accelerate or shift properly when driving with fault. fan clutch replaced, computer programming changed with no success of fixing problem. gmc refuses to buy back vehicle. dealership indicates this problem is occurring on all 2002 gmc envoy's at varying levels mine being worse case. vehicle is unsafe for use in any traffic situation as the problem manifest itself rapidly with severe loss of engine power, loud noises from engine and poor shifting and acceleration.*ak

When driving and without any prior warning vehicle suddenly stalled, causing loss of all power. problem has occurred five times since purchase date. consumer has contacted dealer.*ak consumer states after each filure, vehicle does not shift properly, the engine must reach a high rpm to shift transmission, even after shifting engine, the transmission makes an excessive noise, vehicle acts if though it is pulling heavy load, symptons persist for 40 to 50 miles after failure.*jb

Re odi#10026102: vehicle with stalling problem brought to dealer who detected no defect. dealer unable to rectify problem. i hope stalling problem does not occur at highway speeds as it has with other vehicles, same make and model.dealer stated wandering driverside mirror fixed. we'll see.*ak
