Suspension & Steering -- Verified

The steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.

Electrical & Lights -- Verified

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.

Engine -- Verified

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.

2003 Chevrolet Suburban 1500 Reviews

We have owned a 2003 Chevy Suburban with 130,000 miles and have continued to enjoy this vehicle. I do understand that if you maintain it, the engine can last for a long time. I actually sold my Toyota Sequoia because it had nothing but transmission and electrical issues. The Suburban seemed to accommodate my family better and had more room including better ride comfort. I do want others to know that the Transfer Case for these vehicles will tend to make a small hole causing a leak and this will be costly. Also, with these many miles, I am ready for a rear main seal and front driveline output shaft seal, but lucky for us we have someone that can help in repairing this project. Again, there are no perfect vehicles and not everyone will have a non-issue suv but if you do, great! if you don't, find something that would work for you and your family. So far, we are really enjoying this suv and what it has to offer.

I have had my suburan for 5 years and i have nothing bad to say about it the only trouble i have had is out of the tramission at 80,000 miles other than that brakes,oil changes, and we bought a battery, great truck and i bought it at 62,000 miles it has 140,000 on it now we are getting a new one

I have a 2003 Chevy Suburban Z71. It has been nothing but head aches since I purchased it 2 years ago. First the factory amplifier for the rear speakers went out, then the rear air conditioning stopped working, next the air vents up front stopped working (you could not change between defrost, floor, or vent..etc.) then the anti lock brake controller died and I have had constant brake issues ever since. this vehicle has been the worst I have owned.

2003 Suburban...A great vehicle. Only problem in 82,000 miles has been a rear window regulator. Milage has been good, pulls my boat with ease. This is my second Suburban and I'd buy another.

My truck has been very dependable and versatile, whether taking my family of six on a 2000 mile road trip or hauling loads of sheetrock and yard debris. Trim seems to hold together, except the color coating on my dashboard is peeling off -- revealing its true color, black. Paint has stayed true. Suspension handles well on and off road. It's a nice tough truck.
