Chevrolet Suburban Wiring Problems - part 1 (2024)

I noticed corroded and what I would call charred or burnt wiring on the wiring harness for the rear lift gate of my Suburban. I noticed it when I opened the lift gate to gain access to the rear of the Suburban. It appears that the rubber grommet material protecting the wiring harness, was burnt or melted away. The rubber hose that supplies water to the rear window washer/wiper had a hole in it, and may have been leaking windshield washer fluid onto the wires for a time. The wires were bare in some spots, some of the wire insulation looked melted/burnt away, and they looked corroded/with a green color to them. The connector that connects the harness, to the rest of the electrical system, looked like it has some black/ possibly burnt residue on it. I can take a guess at best, that because of the hole in the rubber hose, water may have been leaking onto the electrical wiring/connections when I used this feature to clear dirt from the lift gate window, but I don't really know for sure if that is how the damage to the wiring harness has occured! thanks!.

The contact owns a 2007 Chevrolet Suburban. While attempting to start the vehicle, it began to shake and the check engine light illuminated on the instrument panel. The vehicle was taken to the dealer, but the failure could not be duplicated. While driving at various speeds, the vehicle began to slow down and the reduced engine power indicator illuminated on the instrument panel. As a result of the failure, the vehicle was almost t-boned by a tractor trailer. The vehicle was able to be maneuvered to the side of the road where it was restarted successfully. The vehicle was taken to the dealer where it was diagnosed that the throttle body and the brake switch would need to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was brought back to the dealer where it was diagnosed that the wiring to the ecm connector 2 and wiring harness needed to be changed. The vehicle was repaired, but the failure recurred shortly after the repair from the dealer. The manufacturer was made aware of the failure. The failure mileage was 67,200.

I just recently began having trouble with my 2000 chevy malibu and it prompted me to being researching common issues with Chevrolet vehicles. In my research I came upon an interesting fact that several makes and models seem to have intermittant turn signal functionality and hazard light issues. In my case my 1995 Chevrolet Suburban (which I love mind you) was being checked for a trailer to be hooked up. When the person performing the inspection attempted to turn on the hazard lights it caused a malfunction with all of my turn signals, breaks, hazards(no equipment was attached to the truck so no it wasn't a faulty connection to the trailer, that had not been attached yet. ) after several minutes of messing with signals and pushing buttons it finally reset to normal. This funny wiring problem occurs every time I try to turn on my hazard lights. Up to this point I have not had a need to use them but I am aware that they will not work if I attempt to. My advise to anyone reading this is if you are having trouble with your turn signals mess with the hazard light button before you go replacing flashers and bulbs. It took several times of pushing the hazard button and turning the signals on and off before they started to work again. I am very disappointed with chevy that this issue has not be address now that I am finding it to seem so common a problem. I was even more disapointed to learn that my malibu has issues that are similar to others with that make and model and those issues are ignored as well. A side note if you read my other complaint. The 1996 chevy s10 my spouse and I were going to trade the malibu for also has fuel issues. What a bummer I used to really like chevy. Channel 9 news anyone. "NHTSA it shouldn't take someone dying before you make them fix it. If it is a known problem that can be proven is not normal ware they should have to fix it. ".

"reduced engine power" light comes on and truck slows to less than 10 mph and the power steering stop working. This has happened six times in the last year. 1st incident I took it to the dealer and they said nothing was wrong with it. Diagnostics performed and nothing came back wrong. I think the wiring to the throttle is possibly to blame. If I hit a bump in the road or cross railroad tracks, the reduced engine power can come on. I have a hunch after researching online & finding that several other people have the same problem, that leads me to believe that chevy knows about it & is doing nothing about it. "typical"!! I am very displeased, especially because I love my Suburban. I suggest an investigation & recall of this problem. I ask that chevy takes responsibility for poor quality & repairs the problem pronto! OH, and the power seating fuse caught fire and exploded the little fuse in the fuse box, now the seats won't work & neither does the passenger side windows. The wiring done on this truck is cheap! the parts are cheap! not a happy customer!.

The contact owns a 2001 Chevrolet Suburban. The contact was driving approximately 55 mph when he noticed that the fuel gauge displayed empty which was inaccurate; however, the vehicle suddenly stalled. The vehicle was towed to his residence. The contact repaired the vehicle by replacing the fuel pump module. The failure mileage was approximately 69,000. Updated 08/24/10the consumer stated the electrical wring in the fuel pump module had melted the insulation and was causing a short in several placed. Updated 08/24/10.

A short in the wiring that powers the heated seats and power drivers seat. Connector is burned and melted. As a result of the short, my battery has been drained twice. Luckily this was found before a fire or serious injury.

Vehicle fire- started truck, turned on front and rear heater and defrosters. ~2-3min later, the truck was completely engulfed in flames and smoke. Caught a second car on fire and house on fire.

Our speedometer quit working and would either sho us going much slower or much faster than we really were. We were hoping that it was just a sensor, but it was the wiring in the dash, they required that we send in the whole front module and they sent us a new one with our old odometer miles already set. They also required that we send in the old one. Our mechanic told us that they had just had to replace a pickups speedometer as well. Same year, and similar model.

My wife drives a Chevrolet tahoe 2003 LS with about 48 000 miles on it. Recently I was driving on the interstate and noticed the speedometer was showing 90 mph. I looked at other cars around me and decided may be I was going a little fast. So I slowed down a bit. The speedometer went up to 100. After I pulling over and stopped it went down slowly after I stopped. During the next week, the speedometer continued to increase and eventually stuck at the highest speed. So I made some calls to various dealers , and was told that several people have had this problem, and that it was going to cost $500 to fix the instrument cluster. I think this is a safety issue and want to notify Chevrolet. I think this is their problem. I don't want to pay for this one. Yesterday evening, the speedometer appeared to be working again. This time I've noticed it will track on the right speed and then have to come to a complete stop to sort of reset it.

A fire started in the electrical system behind the glove compartment while driving 20 mph. Consumer extinguished the fire with a fire extinguisher. Vehicle was towed to the dealer, but dealer did not determine the cause of the fire.

The vehicle caught fire in the engine compartment while the consumer was waiting at a traffic light. The fire was extinguished . The vehicle was towed to the dealer. The cause was determined to be a faulty ground wire.

Wiring to fuel pump inside of gas tank getting hot enough to melt wire insulation and plastic connector resulting in gas leak at fuel pump module. Had replace fuel pump module, but its my concern that a fire could be caused by overheated wires inside of fuel tank.

Fuel pump wiring melted inside gas tank and caused vehicle to stall at highway speed in heavy traffic. Power steering and power brakes were lost making it difficult to control vehicle and safely get to the shoulder. Mechanic who replaced the pump owns an older Suburban and had his fuel pump fail multiple times until he replaced it with an aftermarket pump.

When attempting to adjust the drivers side mirror consumer noticed that drivers side door started smoking, and the mirror caught on fire. Consumer was able to put the flames out. Took the vehicle to the dealer for inspection.

Center console with rear climate and radio controls stopped working. Took it to riverton Chevrolet, and they replaced some faulty wiring.

While making a turn light came on indicating brake system failure in a matter of seconds. Then, everything shut down. Consumer lost the ability to steer or brake. After struggling consumer managed to pull the vehicle to the side of the road. After waiting a few minutes consumer attempted to restart the vehicle, but it would not turn over. It had no power. Consumer had the vehicle towed to a Chevrolet dealer for inspection, and mechanic determined that a short in a fuel pump wire caused a fuse to blow out, which in turn, shut down the entire system. Consumer stated that dealer put vehicle on the diagnostic machine, and the main computer showed no failure. However, prior to this incident there had been some other electrical problems.

Seat belt straps in the driver's and middle seat in the second row become tight to the point that the passenger must unbuckle the seat belt and reattach as the ride progresses. Also, the middle seat belt has released on a number of occassions sending my daughter flying to the front of the vehicle in her car seat on hard braking. Second, the audio controls behind the center console become extremely hot, even more so when they are in use.

Fan switch located on the dashboard that controlled the air ventilation melted the wiring harness. Dealership replaced the switch and the wiring harness twice. Dealership indicated that this was a high demand part.

We have had problems with three systems. At about 30,000 miles, a front and rear brake repair was done which cost over 600. 00, claimed to be normal wear and tear and not warranty. We have had to replace tail light circuit boards twice. We are on our third battery. The initial battery leaked acid on itself and other car parts and my garage floor. The second battery would not stay hooked up to the wiring harness and caused numerous failure to start problems(when the car was only two years old). The most distressing problem was the recent replacement of transmission at only 70,000 miles. The car jerked between second and third gears, made noises and rattles. Red liquid was leaking onto my garage floor. The car was towed to capitol Chevrolet dealership in austin. I reviewed my problem and told them I thought I had a transmission problem. They decided it was an engine coolant seal problem and performed a 600. 00 repair. I picked the car up and drove one block and the same problem occurred. The car was driven back to the dealership, and we were then told our transmission was "burned up". I think it is ridiculous that a car would need a new transmission after 70,000 miles. The car is in top condition, stored in a garage and serviced as required. After reading customer complaints about this year model, in particular battery acid leaking onto brake lines and transmission problems, I felt I should report my problems.
