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.

2003 Chevrolet Suburban Owner Comments

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.

I will be driving down the road both hwy and city. The Suburban will go into reduced engin and lose all its power and speed. I have to pull over and cut the car off and restart it and it's fine to go for maybe a mile and it does it again. They can not pin point what the problem is. It's very dangerous.

The contact owns a 2003 Chevrolet Suburban 2500. While driving 35 mph, the contact depressed the brake pedal and it traveled all the way to the floorboard. The contact was able to stop the vehicle. The vehicle was towed to an independent mechanic where they performed an interim repair. The vehicle was taken to an independent mechanic where it was diagnosed that all the brake lines were rusted and needed to be replaced. The contact was also informed by the independent mechanic that the vehicle may need the fuel pump line replaced as well. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 72,000.

Suburban 8-cyl

  • 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.

Suburban 8-cyl

  • 53,817 miles
I purchased this Suburban new in 2003. In may of 20011, I suddenly had no brakes when backing up and going forward in parking lot after driving from home to store. Took the Suburban to olympia, Washington Chevrolet dealer who said cause of the brake failure was due to rusting of brake lines that were leaking and recommended replacing all brake lines. In the previous weeks, I had driven the Suburban on mountain roads in national forests in the area that were unpaved and had steep inclines, was lucky not to have had a failure on those roads or on paved highway at high speeds on the trip home. All break lines were replaced. This required removal of the fuel tank. A few weeks later the service engine check light came on I took the Suburban back to the dealer who determined that the problem was the front fuel tank vent that was also rusted and was not functioning properly. This required replacing the fuel tank since the vent was not sold separately!! the new tank with vent cost $829 dollars bringing the total cost over $3,000 dollars. Note, I also purchased a 2003 Honda Accord new, which I still have, and have driven it for over 70,000 miles and in the same environment as the 2003 Suburban, and it has no signs of rust on the brake lines or fuel lines. This seems to be a common problem with Suburban of other model years and it is a life endangering failure. I feel I should be compensated by Chevrolet for these repairs and a recall issued all Suburban to check for this rusting of the brake and fuel lines to avoid loss of brakes that could cause an accident and loss of life.
