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.
ABS Warning Light On and/or Erratic ABS Operation
Brakes --

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.
Windshield Wipers May Fail Due to Faulty Wiper Motor Control Board

The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

Body, Interior & Misc., July 21, 2005

The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.

My wife and I just bought our 2001 Suburban 2500 with only 89,000 miles on it. For one we got a great deal, and two this vehicle is by far the nicest and most comfortable vehicle we've ever owned. The second row bucket seats make it so much easier for our kids to get in and the leather is great. I've always been a fan of the 6.0 Liter engine and ours came with a polished K&N Intake kit too! The engine is MORE than capable of making the beast move. I can barely tell my trailer's back there when I hook it up. Bottom line, we love this car, its big and strong, yet extremely comfortable and definitely gets a lot of attention.
Hard to criticize this vehicle. I bought it new in 2000 and put 20K miles on it every year. I replaced a radiator and the transmission was repaired under warranty at about 100K mile. It has never been garaged and the paint hasn't even oxidized.
