05 gmc sierra speedometer erratic at first,15,000 ml.,now at 62,000 ml. Doesn't work. I was going 50 at a stop sign. I have my own business and pull trailers w/ equipment and the right speed is critical for the towing weights. The law enforcement agencies will never take a faulty speedometer as a reason for going over the speed limit. Interstate driving is at a minimum because going with the flow will mean over heating of the small trailer tires on the tilt bed trailer. No action yet it just quit today,1-4-2010 , and I am filing this complaint to add to the numbers of others that have already filed.
2005 GMC Sierra 1500 electrical complaints
Page 3 of 3: complaints 41 to 67 of 67, newest first, as owners wrote them.
Speedometer sticks and doesn't return to 0 and continues to rise every time the vehicle accelerates until the speedometer is pegged out and then it sticks there.
The speedometer of my gmc sierra 1500 is erratic when it is wet outside. When the vehicle is parked and the ignition key is in my pocket the speedometer reads anywhere from 40 to 50 MPH. While driving the speedometer indicates up to 120 MPH. How many people have to complain about this safety concern before something is done. A search of your database indicates many complaints. Help.
The speedometer in my gmc truck keeps on getting stuck. I have been told by many other gmc and chevrolet owners that have had the same issue that it is in the brain of the vehicle. It happens on the freeway the most. If I don't know how fast I am going I am I am creating potential hazard. If the speed limit is the recommended safe speed. I don't know if I am in compliance. Not only is it a safety issue it is also a financial risk in terms of tickets. All chevrolet and gmc truck owners I know have had this problem.
The connector that plugs into the blower motor under the glove box became too hot and melted the plastic resulting in the A/C and heat not to work (this includes the windshield defroster). I've been looking up problems and solutions and found that this is a recurring problem with gmc and chevy trucks yet there has not been any recall, in fact the dealerships have an extremely overpriced kit to fix their faulty wiring. About 66,000 mi.
Gmc sierra 2005 speedemoter bad, cannot tell what speed I'am going. 37.000 miles on truck...
Speedometer not working correctly, only have 48,000 mile on vehicle ,sometimes it works fine other times it may stick on 50 or 60 or may not work at all. If it sticks on 50 for example when I start my next trip it starts at that point,if I'm going 20 MPH it says I'm going 70 MPH,ect.
Speedometer stopped working at 20000 miles. It was working fine then started to work only occasionally and has now completely stopped working. We have not had it repaired as of yet. It is very unsafe to drive not knowing what speed you are traveling at, plus can result in traffic violations causing your insurance to increase.
At approximately 66,000 miles on my 2005 gmc sierra 1500, the speedometer started reading 70 MPH while the truck was stopped, and rose from there as it accelerated. The condition persisted for about one week; each time the truck was restarted, the speedometer reset itself to a lower starting speed, until it read zero again when stopped. It is behaving normally now, but this seems to be a recurring issue with this vehicle, and gm has not provided other owners any relief if the vehicle is past its warranty period. Something as basic and necessary to driving safety as speedometer function should, in my opinion, be designed to last the vehicle's entire intended lifespan without systemic failure.
2005 gmc sierra speedometer acting erratic - vehicle in stopped position says going 105 km/h or 65 MPH ?? Incorrect readings, jumpy -.
Speedometer has quit working properly. It sometimes reads inaccurately low and sometimes inaccurately high. It will usually go several weeks without ever working properly and then will work for a few days. It sometimes never comes back down after peaking at the maximum speed.
I'm currently at 84,000 miles on my 2005 gmc sierra, and when stopped with the truck in park my speedometer is showing 90mph then proceeds up from there while driving. I think there's something that needs to be done. I have several friends with the same year model vehicles manufactured by gm. All have the same problems. Talked to a dealer about getting it fixed they told me it was going to cost 300 for the part, and 200 dollars to have it programmed....
There is a known issue with gmc vehicles where the odometer quits working after 70,000 miles. There is, I believe, a recall on the 2003/2004 model year. I have a 2005 gmc pickup that has the exact same part in it as is also defective. It gives inaccurate readings or pegs at 120 or 0. This is very dangerous. If it wasn't so expensive, I'd fix it myself. But this is a defective part put in the vehicle by gm and should be fixed by gm.
After 70,000 miles the speedometer stopped functioning correctly. It will read 120 going 70 or read 20 going 50. So its reading too high and too low. Also it seems it is starting to have other electrical issues as well.
I have a 2005 gmc sierra z71, about two weeks ago I was driving in the country only to glance down and see 95 miles per hour, I braked hard only to realize I wasn't going that fast. After pulling over to the side of the road I noticed my speedometer read 35 at a complete stop. Since then it has worked some days other days it will not read beyond 50 miles per hour or it will be some bizarre reading. I have owned the truck for 3yrs 6 months it has around 31,500 miles under mileage warranty of 36,000 miles but 6 months past the time warranty.
2005 gmc sierra speedometer malfunction. Dealership states a new instrument cluster is required to fix the problem.
I own a 2005 gmc sierra and the speedometer has failed. I own a GPS so I use this to help determine the speed I am traveling. I brought my vehicle into the dealer on several occasions and contacted gm and they stated they could not help me that I would have to pay $380.00 to get it repaired. Two days after bringing into my local dealer I received a letter in the mail stating there was a class action lawsuit against gm for defective speedometers on certain makes and models.
Tl*the contact owns a 2005 gmc sierra 1500. While driving approximately 5 MPH, the contact released the accelerator pedal in order for the vehicle to coast. The vehicle then stalled. She shifted the gear from drive into neutral and restarted the vehicle. Later that week, the speedometer displayed 55 MPH while the vehicle was in park. While driving to her place of business, the speedometer displayed 100-120 MPH. Later that day, the contact drove the vehicle to the dealer and was informed to bring it back for a diagnostic and repair. The manufacturer has not been notified. The current mileage was 72,500 and failure mileage was 72,300. Updated 2/2/09 *cn the consumer stated the speedometer became stuck at 47 MPH at startup. The consumer stated he did not know how fast he was driving, since the speedometer was inoperative. Updated 02/04/09.
The instrument cluster panel on my 2005 gmc sierra pick up constantly reads the wrong speed. At times it registers 0 MPH when im actually driving.
The speedometer has been erratic for the last 2k miles but now at 43k miles has completely died.
I was driving my 2005 gmc sierra 1500 truck and the cab filled with smoke the a small fire developed on the wire bundle that connects to the fan blower under the dash passenger side. I had to pull over and pry the burnt connector off of the resistor / blower hook up. The fuse did not work and the connector continued to burn until I shut off the truck and remove the connector. I plan to take the truck into skillman gmc since a fuse did not blow prior to the burning of the wiring. Also I did a brief search and found others had similar issues with either the gmc sierra and the chevy silverado truck.
Speedometer stopped working. Would manifest itself in a couple of ways. 1) it would show a steady speed of 25 MPH regardless of my actual speed. 2) would show I am going as much as 50mph over my actual speed.
Tl*the contact owns a 2005 gmc sierra 1500. While driving at any rate of speed, the speedometer displays inaccurate readings. The vehicle has not been taken to the dealer. The current and failure mileages were 105,000.
The speedometer failed after 60,000 miles.
Fan speed 5 will not work and speed 4 smell like burning wires, drivers temp control will not work only cold air. Connector under passenger side fan black wire burned into and melted connector. Gmc parts man said there was a national backorder on parts because so many wes go bad.
2005 gmc sierra - if the vehicle sits for 3-4 days without being driven, the battery goes dead. Nothing has been left on.
Electrical system, all my truck lights dim very low when I roll the windows up or down when driving, when I hit the brakes all lights dim and vot. Drops we have taken it in to the shop a lot for this and still no fix. Service engine light stays on and my temperature gauge doesn't work I took it in and they said this problem is only in alaska and there is no fix. Front diff has been a problem since the day we picked it up the have fixed different things on it.
