| 2 complaints noticed enginee running hot, added fluid to radiator, near empty. a couple of months later, same thing. 3 months later, during oil change, mechanic indicated while doing checks that the radiator fluid was low. told him this was the third time, he added fluid, pressure checked radiator - no holes or leaks. seems to be evaporating. air conditioner blowing hot air (excluding the fact the panel with ac controls quick working a loooonng time ago). took in to dealer for repair. after $600 and all day visit with dealer, the piece broken was the size of a 2-4 block of plastic. this little piece just quick working, it was referred as a control switch of some sort under the dash board. sounded kinda hokey to me - i can imagine a compressor going out and you do not have cold air - the name of it escapes me - but the mechanic did indicate there was some sort of technical report out there on it as well. just found out from husband the name of the piece - the actuator door quit. *jb | |||

| Dt: the contact stated while driving, the reduce power engine and oil pressure low, check engine ights illuminated. the vehicle stopped, although, the enginewas still running. the dealership was unable to diagnose a problem, but replaced the tank gasket, gas pedal, and computer chip. this caused the contact to rear end another vehicle. *ak | |||

| Car: gmc envoy 2003 when driving on a highway check engine light came on. reduced power light came on too. engine rpms dropped down to 1100. barely avoided crash. *jb made it to the parking lot. restarted engine few times same problem. executed clear change oil light procedure few times. it cleared check engine light and everything is normal now. the vehicle is equipped with change oil timer and light. it appears that when timer expired the computer rather than turning change oil light on enables check engine light and drastically reduces engine power. when it happens on a highway it can easily lead to a crash. i plan to take the vehicle to a dealership in two days. thank you. | |||

| I own a 2003 envoy sle. we have had repeated problems with this vehicle vibrating and making engine noise. i have taken the vehicle to two different service departments (repeated times). one finally recognized that the noise existed. after they drove two other envoys they determined that the noise was inherent to the vehicle. the sound is like a bubbling metallic sound that cannot be good for the vehicle. nothing has been done to correct the failure, i have been told to live with it. | |||

| After starting the vehicle, letting it warm, the consumer entered the highway at 65 mph , the vehicle suddenly lost power, the check engine light and the engine power reduced light came on. the vehicle would only do 10 mph. the consumer will have the vehicle serviced since this is the second occurrence. *nm whenever the vehicle was cold, the engine light would come on and then the vehicle would lose total speed. *sc *jb | |||

| 2003 gmc envoy with a list of problems **nar**cc the consumer began to hear a knocking and pinging in the engine on cold starts and felt a hesitation when the automatic transmission shifted into gear. after many complaints, it was finally discovered the engine knock was due to shorter pistons in the re-designed engine and the hesitation in the transmission shifting required reprogramming. the consumer was told he would have to live with the engine knock, because it could be more trouble taking the engine apart. on a separate occasion, the engine stalled due to the battery dying. from april 2004 to october 2004 the battery failed several times and had to be re-charged. during that same time the engine light illuminated and each time it happened, the dealer would have to reprogram the engine computer. the radio was not functioning properly which primarily consisted of static. the driver information center control knobs as well as the radio knobs wore out. the front center console was loose. it was discovered that the engine light was coming on because the third stop light that's on the top of the liftgate malfunctioned. there was a short circuit in the stop light. the cooling fan broke, the brakes and the left front head lamp had to be replaced. the rear tail lights, directional and signal lights have been replaced several times. the lug nut broke while a replacement tire was being mounted on the vehicle. the front stabilizer linkage was replaced. the gas tank had to be replaced along with the fuel lines and a seal on the tank due to a leak. the seat belt was designed poorly and the belt cuts into the consumers neck. the drivers side door didn't close properly, the windshield wipers were replaced within the first 2 years. *jb | |||

| One week ago i purchased a 2003 envoy sle 4wd, it has 200 miles on it currently and noticed upon delivery that a molding around the drivers side door is crooked. and 2 days ago i noticed a large puddle of fresh oil under my vehicle, and my oil light went on this morning. i haven't even had this vehicle for one week and i have to take it in for repairs. this does not make me feel overly comfortable about my purchase. *ak | |||

| I am the owner of a 2003 gmc envoy slt, 2wd, and i have had my vehicle into the dealership three times for a problem which i consider an extreme safety hazard. my vehicle has now failed for a 4th time and the dealer refuses to admit that they cannot fix the problem. my vehicle loses power as i am accelerating on to highways and i have almost been hit by trucks on two separate occasions pulling out on to a highway as i am unable to go over about 10 mph and have to pull off the roadway. the vehicle was in for a third time for that same problem back in january. the dealer had it for a week and put over 400 miles on my vehicle to find out what was causing the problem. the same problem is happening again, 6 times in 3 days, and the service manager will not admit its the same problem since so much time has elapsed. after i lose power, my reduced engine power and my service engine soon lights come on. i must pull over and turn my engine completely off and then back on again. the reduced engine power light goes out but the service engine soon light remains on. the first two times the dealer had the vehicle i do not believe they replaced any parts as they felt it was a computer problem. the third time they had the vehicle they did replace some part, but it was never fully explained to me what they replaced. since this is a safety hazard to me and my family, i feel that this problem should be reported to you in case i am involved in an accident and injuries do occur, i want it on record that this problem is occurring with this vehicle. **please note that the incident date i have entered was the last date it has occurred, i just started keeping a log since it started happening again** *nm | |||

| Throat of gas tank leaking on a 2003 envoy. reviewing internet, found many similar problems on the envoy's and stated in 2007 that nhtsa was investigating. mechanic stated very unusual to leak in that spot. also, have replaced both head light sockets due to burning up. have talked to many envoy owners with the same problem. when bulb burns out and the recommended bulb is put in place the socket and wiring gets so hot that the socket is charred and is no longer functional. wires have to be cut and a new socket wired in. *tr | |||
