Overview & Reviews

Finally, the decade-old, full-size GMC pickup based on the C/K gets a complete redesign from the ground-up. Major structural, power, braking and interior enhancements characterize the all-new Sierra. Styling is evolutionary rather than revolutionary, both inside and out.

• Great new features, powerful V8 engine selections, modern architecture.

  Amazing - 1999 GMC Sierra 1500
  By 4eyedfenix - December 2 - 7:16 pm

  I got my truck for work. Was going to get it or a Ford. Glad I got this one. More than enough power to get my oversized tires to start spinning. Ive pulled my fathers 9000 lb boat without any struggle, I would recomend this truck to anyone, it out pulls and performs anything on the road

  Fun to drive, plenty of power to pull all the toys. Truck has a tendency to create rattles in the cabin area, especially at lower speeds

  gmc blues - 1999 GMC Sierra 1500
  By sad owner - November 27 - 10:00 am

  I have a love hate relationship with this truck. I love the looks and performance when it is running correctly but it only rarely runs correctly. Recalls out the gazoo...troubles not recalled to go along with them. Abs kicks in uncalled for, clunk in rear end, shakes, hesitations, misfires, BOTH windows falling into the doors, squealing fuel pump..dealer said "your lucky it aint worse"...many problems in the 99 model that shouldnt be for a SLT Ext Cab Z71 that cost $32000

  Heck of a Truck - 1999 GMC Sierra 1500
  By Kellin - August 26 - 2:00 am

  I have a 99 GMC SLT with the Z71 option. I am extremely satisfied with this truck. I previously owned an F150, the GM beats it in every category hands down. GM also has a far superior service department, this point I cannot stress enough. I highy reccomend purchasing one.

  Z71 GMC - 1999 GMC Sierra 1500
  By Gary Zimmerman - June 28 - 10:00 am

  My Z71 has been nothing short of the best vehicle I have ever owned. I have driven it very much on long trips and it is an awesome truck. It has never let me down in any task I have required it to perform. Im a firm believer in the fact I will be a GMC man forever.

  Great truck. - engine and driveshaft - 1999 GMC Sierra 1500
  By elkhunter - March 2 - 2:00 am

  Great truck if it would not break down so much. Had an INTAKE Value go out at 50,000(yep intake) that was 1000 to diagnose and repair, now the driveshaft shakes and rattles. either the back universal or the carrier bearing.

  Satisfied for the most part - 1999 GMC Sierra 1500
  By Raven1 - October 14 - 10:40 am

  I bought my Sierra used with about 45000 miles on it. It now has 92000. The problems with the power windows are for real. I replaced the driver side motor and I believe that either side could break again at any moment. The transmission went out at about 80000 miles (one of the drums broke). The dash rattles from time to time. Aside from these problems, the truck really has been reliable and enjoyable. The 5.3 has lots of power, but I do notice a difference in the summer with the AC on. I have enjoyed my GMC, but I will look into a ford when buying my next truck (a crew cab), but there is a good chance I will end up back in a GMC or a Chevy.

  Well boys..... - 1999 GMC Sierra 1500
  By twuck - August 20 - 10:53 am

  bought 2wd SLE, 5.3L V8 new in may 1999. still using the orignal brake pads and spark plugs. starter dead at 110K. Started leaking oil at rear seal about 60K. Let leak for the next 60K miles before I had a mechanic replace the seal for $572.00. enough said - its ok to top off with fresh oil. Ive actually drove it around for quite a few days with the check oil message and then had to add 1 full qt. This truck takes my abuse. Trucks gets 15mpg, no matter what. Interior headliner is starting to peel, pass side electronic window cable broke-who designed this??? AC blows as cols as ice. Friends who have newer Chevys have more problems that I. CD player skips now. Very happy with it so far!
