Problems with 2004 Chevrolet Tahoe ELECTRICAL SYSTEM

2004 tahoe (now 81,000 mi) - sticking/misreading speedometer. problem first appeared infrequently approx 3 years ago. it now happens every time i drive after dark and over 65mpr (interstate travel). i have noticed that if anything else is in use at the moment (a/c, dvd player, passenger lighting, windshield wipers, dashlighting) the speedometer always sticks. resetting it requires me to restart the vehicle (depending on where speedometer stuck) up to 20 times. (it resets 5 mpr at a time) i used to be able to pull the fuse and replace it for a quick fix, those days are long gone. *tr

Dt: the contact stated while driving the speedometer became stuck on 0, 30 or 70 mph. she contacted the dealership, who determined the cluster was not working and needed to be replaced. also, she contacted the manufacturer, and they documented the problem. *ak update 1/11/2006 - *nm

When vehicle was left in the rain, the speedometer would become inoperable. dealer replaced entire instrument cluster at $350. dollars. this involved partial pulling of dash to access. three weeks later the headlights stopped working. discovered that the sensor mounted on dash had fallen inside the dash. dealer claims that at the same time sensor un-attached, both headlights burned out simultaneously. they will not take any of the blame, and consider all events to be unrelated. *nm

2004 chevy tahoe speedometer quit working. stays on 55 mph even when engine is off. told it would be about $800 to fix. now oil gauge is not working properly. it does not drop to zero. oil in engine is at proper level. *nm

Memory seat does not operate properly. when you use fob or key to access vehicle seats, climate, mirrors and radio randomly choose their own positions. *jb

2004 tahoe air conditioning unit will stop and start blowing hot air at maximum volume. vehicle must be shut down completely and restarted to correct the issue temporarily. issue has been intermittent since the vehicle was new. gm could never duplicate, no repair ever made to vehicle. on going issue with heating and cooling system. *tr

2004 tahoe trailer tow inoperative. no hitch pack on the vehicle, so i was not overly concerned, but now i have many other indication problems with my cluster and speed control, perhaps they are related. gm will not warranty the known issue with the speed control and cluster. complaint previously filed and gm customer service previously contacted. issue not resolved. *tr

Dt: contact stated the battery failed. the service dealer replaced an air conditioning module. also, while driving and turning the wheel lost braking capability, the pedal went to the floor. dealership verified this wa shappening, but did not know what caused the malfunction. the contact attempted to contact the manufacturer. *ak

So many... where do i start? 1) at 9,000 mi. intermediate shaft was replaced due to a popping feeling in the steering, at 16,000 mi. it is doing the same thing again. 2) at 9000 miles the instrument cluster was replaced due to a faulty tach motor making a buzzing/rattling sound, started making noise again at 13,000 miles took to dealer and said there is nothing wrong. 3) headlights flicker on and off on turns has been to the dealer 5 times since it had 9000 mi. 1st 2 times replaced a plug on alternator and said it was fixed, was not then said the found a bad connector still did not fix the problem. the problem still exists contacted gm and they were no help. 4) exhaust has been popping since new and sometimes after cool down sounds like something exploded 5) engine makes a noise when warmed up took in for service at 12000 miles and they cleaned oil pump pickup tube and said the oil pressure was not correct. this did not fix the problem took back in at 15000 and they stated no problem was found i was told the engine noise was normal. 6) the brakes pulsated when new took back at 59 mi. i was told to drive it and it would get better. started again at 9000 mi. and they turned the rotors. brakes started making a cracking noise in the front took in 3 times found no problem yet when i picked the vehicle up the last time at 15,000 mi the noise went away only to come back a week later. 7) when idling the vehicle vibrates bad!!!! dash will rattle and you can feel it in the steering wheel. i was told this was normal when the a/c was on yet it's worse when the a/c is off. now that a/c is making a terrible noise from inside the engine compartment and inside the climate control box area. 8) engine has a miss at idle. *jb

2004 chevrolet tahoe instrument panel . oil,temperature,speed volts gauges fail. *tr

The driver's seat moves forward unexpectedly when the button for the heat is turned on, making the ability to see the mirror for the blind spot difficult. the doors locked on their own, which prevented entering and exiting from the vehicle. the manufacturer was contacted and was aware of the problem. *ak the memory module that controlled the drivers seat, mirror, locks and foot pedals, did not stay in memory and would go out of control intermittently while the vehicle was in motion. the consumer would become unable to reach the pedal, gas pedal, the mirrors collapsed and had been locked out of the vehicle on several occasions. *sc *jb

Vehicle goes into reduced engine power and engine light goes on. vhicle has been in the shop 4 times for he same problem.
