Overview & Reviews

Reliability improvements for all Vortec V6 and V8 engines top the list of changes this year. Consequently, oil-change intervals have been extended to 7,500 miles. A traction assist feature is now available on two-wheel-drive V8 automatics, thanks to a new electronic throttle control system. Factory-installed OnStar, GM's mobile communications and security system, has been made standard with the SLT trim level. New this year is a 325-horse, all-wheel-drive performance version called the C3.

• Powerful V8-engine selections, handsome styling, comfy cabins.

• Spotty interior fit-and-finish concerns, premium brand carries a premium price.

  flimsy body panels - 2001 GMC Sierra 1500
  By letdown - October 14 - 10:00 am

  Be aware of service bulletin # 01-08-66- 014 which addresses sheet metal fracture with accessories such as tool boxes,and ladder racks. My truck has a rack on it which was also on my 99 GMC(which had no problem in 94000 miles).At about 70000 miles the body panels just in front of the tail lights on both side ripped apart and the bed rails collapsed onto the tail lights. Since I am out of warranty(too many miles, not time) that this repair is on my dime - actually $1800. This was my third truck from this dealer and all of them have used the same rack. They told me that when GMC went to the new body style in 2000 they just arent as strong. BE AWARE!!!

  Professional Grade??? - 2001 GMC Sierra 1500
  By Going Back to Ford - February 6 - 10:00 am

  After 2 Fords with over 100000 on each and relatively no trouble, I suddenly have a hole in my 2001 GMC engine block. The GMC hotline has been very vague about service since I am now at 42000 miles and the dealer tries to ignore my calls every time I try to get an answer if this is a factory issue. If this thing ever gets out of the shop I will NEVER own another GMC product!

  I have become a GMC service expert - 2001 GMC Sierra 1500
  By brad - May 18 - 11:10 pm

  My name is Brad and I have owned a 2001 GMC Sierra for a little over a year. The factory warranty has not expired and I have had to take it back to the dealership at least six times. From the seams on the interior ripping to the oxygen sensor going bad twice, this truck has been a real headache. I have the Z71 model and it is the truck I always wanted but after this one I am done with GMC.
