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!

2005 chevrolet suburban 1500 4x4 flex fuel, 5.3l. This vehicle's instrument cluster does not work. Tachometer pegs and sticks. The speedometer is stuck at zero. This is a very serious safety concern that general motors/gm should do a free recall for as many owners of this vehicle have the same problems. My ABS sensor light comes on and off numerous times a day, and cluster states service air bag. General motors should also fix this for free under a recall as others have the same issue with this vehicle. My third major complaint, is the vehicle starting problem/hard start. It takes two turns of the engine for the vehicle to turn on and stay running. I have researched this on various search engines, forums, and including recall.gov. General motors should address this issues as well under a recall. Gm installed faulty fuel pumps or fuel pumps with faulty components in them. A vehicle should start with one try. I should not have to get the fuel pressure going in the on position, or crank it twice for my truck to start.

The driver side seat heater randomly turns itself on. When you turn it off it comes back on again and randomly cycles through the various settings. It's almost a constant battle trying to keep it turned off which creates a hazardous situation equal to, or worse, then texting while driving as you have to keep looking down to push the button, especially here in florida where you don't need (or want) seat heat in the summer. I've fought this to the point that I've worn the paint off the switch. If you search the internet this is a very prevalent problem with gm vehicles during these model years. I also have a 2006 gmc sierra that does the exact same thing. I've been to at least 5 different dealerships and either they can't fix it or they claim they've never heard of the problem. That can't be true since gm issued a tsb for this problem but the recommended fix (reprogramming the driver door switch) actually does not fix the problem. In fact, when the dealer reprogrammed my gmc it actually made it worse to where it happens much more frequently. I contacted gm and even though I took it to a dealer 4-5 months ago where they couldn't fix it, gm says I have to take it back to the dealer (pay another $100 diagnostic fee) to meet their policy that they will only address the issue if you've been to a dealer within the last 30 days. Some reports are the seat heater elements are shorting out. Either way this creates a very unsafe situation for drivers. Gm says I can pull the fuse for the seat heaters. However, when you remove the fuse labeled "seat heater" it actually does nothing. The seats are still powered and the problem persists. This clearly indicates an electrical problem and design flaw. The only sure cure is to remove the 30 amp breaker under the dash rendering your driver/passenger inoperative. Gm must fix this problem before someone gets killed from being distracted.

I was driving on a trip to florida when at 65 MPH my speedometer kept increasing and pegged out at the 120 MPH mark. I pulled over to try and resolve the issue but to no avail it stayed stuck at the 120 MPH mark. When I restarted the vehicle all my cluster gauges were pegged out: oil, battery, temp, and even gas gauge. I also started getting info that my airbag system needed attention. Four wheel drive light came on just a different array of malfunctions came flying across my display. To this date my battery gauge is still pegged out my airbag light is on, service four wheel drive light still flashes inadvertently and now my drivers side heater and controls are not working correctly. Brought in to repair shop & they said no recall has been issued so my cost would run well over $1500.00. Ridiculous. Own up chevy fix this.

Speedometer very erratic, shows excessive speeds (120mph) or doesn't register correct speed at all. Called dealer numerous times about problem and never told about the tsb only that it would be over $600 to fix. Did research online and found tsb and called again. This is a huge safety hazard and one that chevrolet should address across the board with the vehicles affected by this. Then was told can't fix it because of mileage unless I pay out of pocket. Now needle is stuck at zero and unfortunately being military we don't get paid enough to just shell out $600+ on a whim. Someone needs to make chevrolet take care of their faulty products, if you pay for a premium product you should get one.

A/c system would randomly blow hot air; then fan would run with ignition off; then fan speeds would quit working; finally blower quit altogether. Gm has 2 service bulletins out with exact problem description, but they claim my vehicle not covered.

I have a chevy suburban 2005 my speedometer has stopped working. I also have a 2005 duramax that this has happened to. I would like to see a full blown recall placed on all gmc/chevy vehicles. Apparently these are hundreds of thousands people with this issue across the u.s./ world according to forums I have been on. While there is a class action lawsuit out there for a very limited group of gmc vehicles, making lawyers rich. Instead of taking care of the people whom make this world actually run. This issue needs to seriously looked into. My next step is to get the media involved showing how again the average consumer can get screwed by the big companies. I am not keeping my mouth shut about this. Thank you

2005 chevy suburban odometer is faulty. It stop working properly on my chevy truck. It overshoot the speed all the way to more than 120miles/hr when I do not go over 30miles/hr. Gm needs to take ownership of it. Needs to have recall. It is safety of general public. Please force them to recall for the odometer.

Speedometer stopped working on our 2005 chevy suburban. Started out going from 20 to 100 and not registering the proper speed. Now is stuck at 120 MPH. Cost ranges from 300 to 1000 dollars to fix. Having to use GPS for speed which is a distraction and safety concern.
