Problems with 2003 GMC Envoy ELECTRICAL SYSTEM

Malfunctioning of instrument cluster as described by the dealership. speedometer displays inaccurate speed, other readings on panel flip-flop also. advised by the service advisor that this was a noted defect with gmc and they had already started repairing larger gmc's and should get around to mine later in 2008. yesterday, gmc informed me of a special policy issued for the problem, but only for sierras and yukons (7yrs 70,00 miles). gmc told me they were never notified of the problem with the envoy's. i only have 56,000 miles on this car (first owner). now the a/c has gone of by itself twice this month and the preset stations have vanished. *tr

Speedometer does not work anymore. i can be sitting at a stop light and the speedo will be pegged at 120mph. or when im driving it wont move at all. sometimes...i'll start the car, and the speed will be sitting at 40 mph. has been happening for 3-4 months now. and the dealership will not help me. they tell me i have to buy a whole new instrument cluster ($475+) to resolve my problem. this is a very common issue with these vehicles. *tr

Tach gauge for speedometer started be faulty. read inaccurate to my speed. *tr

Speedometer does not work anymore. i can be sitting at a stop light and the speedo will be pegged at 120mph. or when driving it wont move at all. sometimes...i'll start the car, and the speed will be sitting at 40 mph. has been happening off and on since november 2007. the dealership & customer assistance (800-462-8782) will not help me. they tell me i have to buy a whole new instrument cluster ($475+) to resolve my problem. this is a very common issue with the full size vehicles (2003 and up). gm has issued special coverage adjustment #07187 ( 9/28/2007) to replace , free of charge, this bad cluster but won"t fix the same problem in their smaller suv"s. *tr

The vehicle was in service 3 times within 14 days, gm says the problem was the ignition switch, i say the source of the problem has not been fixed. engine stalled 6 times in moving traffic, the "abs" warning light is on, some time the "check engine soon" light comes on. dealer replaces throttle body injection assembly. next day the vehicle stalls again with same symptoms. dealer replaced ignition switch again. !4 hours later engine stalls in moving traffic. dealer installs event recording device, engine stalls and identified low ignition voltage (6.7 vs 13.6 vdc). source of problem could not be identified, dealer says vehicle is safe to drive. we filed a lemon law claim. *nm

Safety problem regarding control of driver's rear view mirror on 2003 gmc envoy. *bf there had been a strange combination of electrical events centered around the accessories in the left front of the vehicle and the left door mirror. other problems: the seat would move erratically when starting and shutting down, the driver's side door did not lock in sync with the others, the locks would click 4 times after driving one mile, and the control button lights on the drivers arm rest was coming off. *sc *jb

Faulty wiring in brake light caused vehicle to catch on fire. gm has offered to repair but i still don't feel it is safe. *jb

Engine stalling with vehicle in motion or when stopped. 5 stalls occurred within past 1000 miles. sometimes vehicle, chugs/skips just before stalling. vehicle has been serviced 3 times for this problem since october 27th and still not corrected as of this writing. usual stall speed is around 20 mph. one time was driving at 65 mph on interstate, all dashboard warning lights came on vehicle hesitated but did not stall. cruise control always stops working immediately following stalling incidents. has stalled upon stopping at stop light/sign. vehicle has had many electrical problems since approximately 800 miles including windshield washer system failure (twice), abs light illuminating, airbag light. *la

october-03 to march-04, between 800 and 3000 mileage: several dual automatic climate control system problems. temperature would run berserk (very hot in cold weather when set at 55f, no ac in hot weather). the radio would loose its preset stations. dealer could not identify problem (no code was set) and told me to return when condition repeats without turning off the engine. he finally found a code indication communication interruption and low battery voltage. no action was taken. the problem resurfaced temporarily again in summer of 2005. *nm

Upon starting the vehicle and taking off the gear shifted, and then dropped down to the correct gear it should have be in. transmission was replaced within the first six months. also, starter made a clicking noise several times before starting. then the vehicle shut down. *ak

The instrument panel speedometer light came on and off without prior warning. *ak

Consumer complained about a horn problem. the horn worked intermittently. dealer was unable to duplicate the problem 3 times, but was able to correct the problem on the fourth time. *ak

Problems with the software. driver 1 and 2 remotes dont always work. mirrors change by just unlocking. sometimes the electric seat release puts the seat into driver 2 position. transfer case on occasion, all lights start to blink and you can hear the transfer case switching.*ak

The consumer took the vehicle in for the instrument panel not working. the odometer did not show a reading. the side mirrors moved on their own. *jb the radio was inoperative, there were problem with on star, the a/c freon was going into the vehicles interior, fuel leaked from the tank and had run down the left side of the vehicle/door, the bell light and message warned low fuel when the tank was at it's capacity, the liftgate would not latch. *sc

Purchased a 2003 envoy xl on 27 dec 02 - since that time it has been to the garage two times - no clamp on one end of the power steering line (luckily it blew off while still in our drive way - god help us if it had let loose at high speed on a crowded highway) second time was for a bad cam sensor. and we haven't made the first payment yet. first cass number from gmc is s1-68773551 - second case number i don't have yet as i just reported it this morning. needless to say that my wife and i have no trust in this car now - what else will go wrong next.

While driving at any speed engine check light came on and stayed on. dealer checked this problem on three occasions. on each occasion the spark plugs were changed, and the battery cable bolt was replaced.*ak *nm

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
