Best Truck on the market

Original owner. 130k miles. RELIABILITY-I've only had 2 problems, and 1 (speedometer) was a recall. The catalytic converter went out at 115k, but other than that, no rattles, no squeaks, not even a brake job. Overall reliability is good, better than my Toyota Matrix. DRIVETRAIN-GM says this V6 has less HP than Ford's, but this pickup (w/3.42 rear end) sure feels stronger than my brother's (w/3.55). No oil leaks at 130k, no slips in the tranny. INTERIOR-I like it, but most auto critics say it looks cheap. Seats are plush and ride is comfy. Overall reliability may belong to Honda/Toyota, but GM's powertrain sold me. None of the tranny problems typical of Hondas, better engines than Toyota.

I love this truck!

I have owned a Ford F150 extended cab and Z71. I was a little leery of this truck because everybody complained about gas mileage. My Z got about 13 and my F150 got about 14. I'm getting a solid 13.7 so big whoop. I love this truck performance and comfort. My wife drives a Yukon and gets 17. For the 3 difference I'd rather have the quadrasteer and the comfort. I've put 30,000 on this truck and about to turn 50,000 (bought it used). With GM droping the quadrasteer, I plan on keeping it for some time. The big chrome grille let them know you're comin' and the 6.0 let's them know you gone!

i bought this truck in june of 2003. i am very disappointed in the performance of this truck, the service from this dealership, and the warranty work performed. to tell you a little about this truck at 2000 miles the ac went out, at 4500 the heater went out, at 16000 miles the distributor cap went out causing me to have it towed. other things that have gone wrong from the shocks going out, the steering vibrates as you drive, the transmission kicks hard when put in gear. i strongly advise no one to buy this truck.

Too many small problems

2003 GMC Sierra 1500 4dr Extended Cab SLE 4WD SB (4.8L 8cyl 4A)
2 of 4 people found this review helpful

Overall, a nice truck, but too many small problems that are now adding up. So far, I've had the steering shaft replaced 3-4 times, the passenger back window replaced, the heated seats on the driver's side replaced, and now the instrument cluster has gone haywire. Oh yeah, I've been complaining about the awful noise the front end makes when the 4WD is engaged, but the dealership (not where I bought it) says that it is normal. Are you kidding me? I still like my truck as it rides and drives great, but I sold a 13 year old Toyota when I bought this one that was a better truck. I probably won't buy GM again if there are other options out there. Too bad.

Excellent truck. Electronic controls replaced under warrenty. Get 19.5 mpg on a 30 mile trip to work one way. Great sound and very comfortable ride. 5.3L engine that would pull a house up a hill.
