Owner reports

Selected complaints filed with NHTSA by 2005 Chevrolet Suburban 1500 owners, lightly cleaned up (personal details are redacted by NHTSA).

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. …

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. …

I have a 2005 Chevy Suburban. At a little over 49,000 miles my speedometer needle began to report inaccurate readings while the truck was in motion. After a couple of days the needle fell all the way to the right of the panel and wouldn't move. After getting quote from the dealership to replace new and checking with some area junk yards I learned there were possible recalls on other Chevy trucks and SUV's. Once I check on the internet and found numerous people experiencing the same problem. On tonight I called and learned that the 2004 Suburban has a recall but not the 2005 so I opened a case with cheverolet consumer assistance to see about getting my truck fixed as I can't afford $500 to fix a mechanical defect which should be covered Chevrolet expense and not the consumer. …

I have a 2005 Chevrolet Suburban z71 with 59,799 miles. The speedometer on it recently stopped working correctly. The day the speedometer stopped working correctly I was on an hour long trip on the highway. During the trip I noticed the speedometer showed I was going 95 MPH. The speedometer continued to increase even when I slowed down, until it passed 120 MPH where it was stuck for several days. It started to slowly go back down. Since that day then the speedometer continues to show the incorrect speed of the vehicle. The speedometer sometimes reads as high as 120 MPH when the vehicle is not moving, and at other times displays the vehicle going 10 MPH when the vehicle is not moving, and other times shows correctly at 0 MPH. The problem seems to get worse when I drive the vehicle on longer trips. …

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.

2005 Chevrolet Suburban approx. 64,000 miles I have a faulty reading speedometer, which I feel is a safety hazard. I never know how fast I am going. Thankfully I have not had a accident or gotten a speeding ticket yet. I took it in to my mechanic, who tried replacing the speed sensor in the transmission, to no avail. I know there is a recall for 2003 & 2004 models. I tried calling the GM hotline and was told there are no recalls for 2005. I called a local dealer who told me the same thing. I don't know where to go from here. I would like to get it fixed before it reaches 70,000 miles. The dealer did ask if I was the original owner. I assume they would say if I wasn't, they would not fix it. I don't know what that should have to do with anything. What or where do I go from here?

Just got into my 2005 Chevy Suburban 1500. The speedometer stop working. Registering 100mph while I was at a stop light, not working at all while I drove back to the house. There is a lawsuit for 2004 models and only up to 70,000miles. This is a cluster failure affecting thousands of Suburban,tahoe, and similar model owners. The dealerships are charging an average of $450.00 to repair this defect that, judging from the lawsuit is a common problem. It affects my monitoring of my speed and endangers the public and also puts drivers in a bad position with law enforcement. GM is obligated to repair a problem that they had knowledge of. There are too many of these vehicles on the road to allow this defect and potential safety issue to go unchecked.

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

Defective speedometer, have contacted Chevy on several occasions and they refuse to pay for cost. GM recalled same defect on other models except mine which is a 2005 Chevy Suburban. Chevy told me my car exceeded all warranty due to mileage which is in the 80K range. This is a defective part and should be replaced no matter what miles I have on the car. Currently this problem is intermittent so I'm never sure if speedometer is right or wrong. My teenager drives my car and is unable to know what actual speed he's driving. This is potentially dangerous and I cannot afford to repair myself.

Tl contact owns a 2005 Chevrolet Suburban 1500. The contact stated that the instrumental panel clusters do not operate properly. While idling at a stop light, the speedometer gauge displayed 10-20 MPH. The manufacturer issued a TSB for the 2001-2003 models, but not the 2005. The manufacturer and dealer would not repair the vehicle under the TSB. The instrumental panel was replaced in January of 2008 and the contact paid for the repair. He would like to be reimbursed by the manufacturer. The current mileage was 53,296 and failure mileage was 53,250.updated 04/16/08.
