Just turned 100k. Even though this truck has been meticulously maintained and never abused, it has had the transmission replaced (at 67K), sound system (at 25K), intermediate steering shaft (3 times), HVAC controls (at 75K), front rotors (2 times), instrument panel (at 70K), steering wheel control modules replaced (80K), etc. There is so much slop in the drive train that I would never consider using as a tow vehicle. Good for going to the dump and grocery shopping. Limited slip (rear) is demonstrating signs of impending failure, just a matter of time.
Aftermarket navigation system and Magnaflow exhaust. Auto headlights. The 5.3 is a fantastic engine. 4-wheel anti-lock disc brakes work very well when the front rotors are still true.
GM needs to admit the 4L60E transmission is fatally flawed and fund repairs.
At about 53,900 miles, my 2004 5.3L developed a ticking noise.
Turned out to be cracked cylinder heads.
$3800 repair bill.
I had it repaired and traded it for a brand new Tundra with 5.7L engine.
Color - black.
If GM would have stood behind their product, I might have bought another one.
I bought this truck 3 years ago with 120000 miles on it and it just purrs.
Smooth, quiet, comfortable and even with all those miles it still doesn't burn or leak any oil.
I haul a 260 gallon water tank in
the back and it doesn't even phase the old girl.
Just a great truck!
Comfortable and quiet with more than decent mileage for a truck.. (22 mpg hi-way in Canadian gallons) Controls on the steering wheel, power/heated seats and auto headlights.
I wished the center console would lift up out of the way to make room for an additional front seat.
This truck is a life saver for me, got into a car accident was going 85 and hit a telephone. I truly believed it saved my life, i just bought another one same year. Truck has a amazing build! i would tell anyone about this truck and how amazing it is.! i absolutely LOVE it.
