Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The anti theft system caused the engine to quit going down the hi way several times and was very dangerous some of the times and left us stranded sometimes. GM acts like they do not know what is wrong but there is ample info on the internet and even a fix but it disable the ats, it turns off the fuel to the injectors killing the engine. This happened many times. We had to be towed twice because it would not restart.

Vehicle suddenly started going into reduced power mode and providing an error code indicating a problem with the throttle control sensor. From the hundreds of online posts (some by GM mechanics) this is an ongoing problem with many 2003-2008 trucks and SUVS made by GM. When I began trying to repair this problem myself, I found out from my local Chevy parts department that "they can not keep these throttle control assemblies in stock because we are replacing so many of them..." there seems to be a know problem that GM is not adequately being proactive about. This happens while driving highway, local streets and at startup. This becomes a serious safety issue when the vehicle goes into reduced power mode while the vehicle is in traffic.

All gauges in instrument cluster went low or no reading, including speedometer, fuel, tachometer, temp. The repair was done at willie's auto repair 901 S. cliff ave. In sioux falls, sd. The GM remanufactured instrument cluster part was $453 and labor was $126, with tax the total cost of the repair was $613 which GM should be paying for !! I know several people at work that have had to have this done to their GM trucks and Tahoe, Suburban. This is so widespread there should be a class action suit !! you know the component they replace can't be much on a board in these "remanufactured clusters" GM needs to replace these at their expense !!!

The rear lift tailgate and window will not unlock when using the remote key button, or when using the unlock button on the drivers door arm rest. There is no manual key lock for the rear lift tailgate or window, nor any inside button to manually unlock the tailgate. When sleeping in the rear of the Suburban you have do way to exit the car except by climbing over seats and exiting using the front doors. Driving the car and stopping to try to unlock the rear lift gate will eventually allow you to unlock the tailgate, some times after many tries. Also it some times will unlock when alternating between the driver door unlock button and the remote unlock button. This could be a dangerous problem. This failure of the rear tailgate is a common problem with Suburban. This link provides more information on this problem: " "

Suburban 4WD 8-cyl

  • 93,300 miles


My '03 Chevrolet Suburban has developed what appears to be a very common condition where the entire instrument cluster becomes inoperable. For example, while traveling at low, in town speeds, the speedometer will have readings in the 60S, 70S' and 80S. While in the park position, the speedometer will read 55mph. This is absolutely a safety issue and I am really shocked that the NHTSA hasn't forced a recall. There are literally thousands of reports online of this exact problem. General Motors is aware that this is a wide spread problem, as they even extended. General Motors even provided owners with a special coverage that extends the warranty on the instrument panel cluster for the condition described above, as long as the vehicles age and mileage falls within certain parameters. Those parameters are the main reason for my complaint. Those parameters are 1) 7 years of the in service date, and 2) 70,000 miles, which ever occurs first. My claim to have the instrument cluster in my vehicle repaired under the special coverage was denied on 9/4/09 because the mileage of my vehicle was 93,000 miles at the time of my request. I believe that this is a large scale safety problem that warrants a recall by General Motors rather than an extension of warranty with unreasonable mileage parameters. Extending the warranty alone is a clear admission of a known widespread issue. Is NHTSA in bed with GM too? I guess I shouldn't be surprised.

Suburban 4WD 8-cyl

I am a teacher and got a call in my classroom that my Suburban was on fire parked in the parking lot. The fire department was called and when I got outside, sure enough there was smoke all in the Suburban and smoke coming from the roof of the vehicle (not the hood). When the fire department arrived, they entered the vehicle, disconnected the battery, and proceeded to tear out my rear headliner to extinguish the electrical fire that was occurring. My insurance company had the vehicle towed and it was deemed reparable, which I was not too happy about seeing as we don't really know the cause of the fire beyond electrical. The fire originated near the rear dome light and burned the headliner and melted the paint off the roof the vehicle. The location of the fire was not a in a place where any mechanic could check to have prevented this from occurring and I am concerned about the safety of the vehicle moving forward. I am not in a financial position to afford a new Suburban and do love mine, but am now just concerned. I am thankful no one was in the vehicle and that no one was hurt.. but had a parent dropping a kid off to school not noticed the smoke coming off the roof of my car in the parking lot, things could have been much worse. I had also just filled my tank up the day before so the car was sitting with 30 gallons of gasoline in it. I am also thankful that I was not trying to scramble to get my 4 kids out of the car (and yes we do use the 3rd row seat daily). I think this incident needs to be looked at to prevent any other owner of a 2003 Suburban from having a similar experience. There were no recalls on my vehicle that would have lead to this issue.

I can unlock truck with key or remote put key in start and dash lights come on but no start. After being told it was the fuel pump, the started, and key I know it has something to do with the anti-lock. I have reprogrammed it several time but each time a different way. I have research it on line and it is a on going problem with GM cars and trucks. However I am not sure if it is a recall. I am recently the second car owner of this truck and experiencing this major problem. I am a single mother with children and grandchildren and this is not good for me at night or during the day if at a shopping center. I have had to have it towed to my home then the next day it started. If any one can help me please email [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

  • 125,000 miles
Ever since we purchased this huge pile of junk, it has been every problem to changing fuel pump several times, catalytic converters, batteries, major electrical problems, every gauge in the vehicle is off from gas gauge to speedometer to coolant! there is not anything that is not wrong with it. After thousands of dollars and so many times of being stranded on the side of the road with 4 little kids in the dead of winter with no heat. I would like a lifetime warranty from Chevrolet to cover any expense incurred while owning such a piece of crap and for the humiliation I have incurred by being seen in a Chevy because they are junk!!!!!or would like book value of vehicle so I can go buy a Ford because they run for 250,000 miles plus!!! not 125,000.

I was driving my Suburban back from work one day and my front A/C blower stopped working. I turned A/C off and reached home. When I took the plastic cover over the blower motor apart to see what is going on I figured that the electrical connector to the blower motor resister has heated up and melted. I replaced the blower motor resister thinking something was wrong with that only to find out it happened again 15 days later. I searched the problem online and found that yet another engineering disaster by GM. It appears to be a known problem in GM trucks. For some reason the blower motor resister is overheating and melting the plastic connector and wires connecting to it. This is a fire hazard. I called up a Chevy dealership near me to find out if there was any recall on this they said no. Hence reporting this to you.

I was driving my 2003 Chevrolet Suburban down the road and my speedometer stopped working. I looked online and I found over 40 incidents on alone. Whats the problem with getting this safety problem fixed. I can go to the dealer and get it fixed for $500 or more. Do people need to get hurt or die before this problem is noticed by Chevrolet or GMC?

Just finished driving vehicle for 1 hour at highway speeds without incident. Parked car for 5 minutes, upon trying to restart, the car displayed "reduced engine power" on the driver information console. Approximately 8 restarts and the message did not display. Drove car 5 minutes and parked it for 1 hour, upon restart displayed same message, car was virtually undriveable. 3 restarts later message no longer displayed. This message has now intermittently occurred ever since seemingly without any pattern. The message is related to a failure in the "drive by wire" system that allows for the elimination of a physical cable from the gas pedal. It causes the car to be completely undriveable until seemingly randomly fixing itself.

2003 Chevrolet Suburban HVAC blower not fully functional on all blower speeds..service bulletin 11046, April 2010..Chevrolet has known defect wiring connector and electrical terminals of relay resistor module as described in service bulletin which results in blower motor not functioning on certain or all blower speeds setting. GM has issued special coverage adjustment for up to 10 yrs per bulletin but refuses coverage purportedly based on my vehicle not being in the special coverage VIN: Two phone calls to customer service resulted in a hang up, put on hold and not returning to the call, and upon escalating the call to joy, the supervisor refusing to further assist...and refusing to escalate the call further explaining no manager is "likely" available, we've told you your answer....GM case #71-107-8244378 2nd issue with electrical; instrumentation cluster fails to work properly and digital display which indicates whether you are in park, reverse neutral drive (gear) dims or goes out completely. Same problem I had on 2005 Chevrolet Suburban 1500. Both vehicles they have refused to fix. 2003 had special coverage 07187 to repair this condition but the previous owner was not properly notified to fix this condition during the manufacture special coverage period.L they know it exist but once again are using any excuse to do the proper thing and fix the problem. Also reported under 71-107-8244378 request NHTSA and appropriate agencies further investigate these matters and hold GM accountable do not let GM continue to skirt recall repairs for known problems by narrow defining which vehicles they have to fix. Recalls should cover all vehicles that have identified safety issue and GM should facestiff punishment to encourage them to voluntarily fix problems rather than stonewall, stall, avoid, and make it more difficult than fixing the problem.
