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.

  Despite problems - still love this truck - 1999 GMC Sierra 1500
  By tlechner - September 12 - 10:00 am

  Overall I really enjoy this truck. However I am worried about when the warranty runs out. I have replaced both power windows motors, drivers side twice. First time was when the truck was only 2-3 months old. Steering box - replaced at about 50K. This truck does move. The tow/haul mode is great.

  QUICKLY ILL SAY THAT MY GMC HAS BEEN A COMFORTABLE, DURABLE, RELIABLE TRUCK FOR THE 2 YEARS IVE OWNED IT. VERY POWERFUL TRUCK, THE ONLY COMPLAINT I HAVE ABOUT THE TRUCK IS THE CHEAP, BLAND INTERIOR THEY MAKE. OTHER THAN THAT A GREAT TRUCK TO OWN.

  By badblacksierra - December 25 - 7:03 am

  i have a 99 sierra 4.8 sle with 400,000kms and still runs like new on original motor and transmission these are amazing trucks !!!! give them the regular maintenance they require and it will never die , it is still my daily driver , and by far i would NOT trade my 14 year old truck even for a 2012 , this truck still has beaten a 5.7 ram and a f150 (ram was a 2009) (ford was a 2007) and literally beats them both in every test i put it up to , and its 14 years old!!! bravo GM with this truck you have won me as a customer for life!!!

  This truck has been very reliable and it still looks great. It has pulled whatever we needed it to. We have pulled cars from CA to MO and back with no problems.

  Back to the Blue Oval for me - 1999 GMC Sierra 1500
  By Turtle316 - November 10 - 2:40 am

  My 1999 GMC Sierra 1500 is the first non Ford vehicle that I have ever purchased, and this truck alone has been enough to make me never buy a GM product again. The drivers side window stopped moving, so I took the door panel apart and the motor assembly is barely accessible and a nightmare of a design on top of that. My transmission has started to go out at only 65,000 miles and two wheel bearings went out at the same time. Not to mention that I get between 12 and 13 miles to the gallon driving in this ridiculous California traffic. One more thing, if the turning radius were any larger I would need one of those guys with the flashlights that direct the pilots when pulling into the terminal.

  A nice Truck - 1999 GMC Sierra 1500
  By Sierra152 - September 10 - 2:00 am

  I just got this a few day s ago and here are my first reactions: I have the 5.3 V-8 and it preforms well. Although it doesnt have the power of my Z-28, it can move fast enough. The ride is better then the fords I looked at. The Auto 4WD is good, but you may want to turn it off for parking. It is very comfortable and fun to drive, it is a truck that you can do stuff with like moving and off road driving but it can be driven every day. I will try and write an update after i have drivin it for a while.

  BIg Red - 1999 GMC Sierra 1500
  By the Big Red - June 30 - 2:00 am

  Got this veicle as a left over in 2000, didnt want red, but it has grown on me, the trucks styling is modern, but not over board like a Dodge, and does not look like the sheet metal was hung on the truck like Fords, it is what it is supposed to be a pick-up truck, not a tractor trailer or a car. Reliable with close to 50,000 miles, nothing more required but routine maintenance, and new tires. it looks good sitting in the driveway. I would recommend a GMC to anyone,it rides well, and looks good and works hard.

  No more GM products for me. - 1999 GMC Sierra 1500
  By Wham - January 17 - 10:13 pm

  Problems before 05- transmission went out, ABS quit due to computer glitch, seal in four wheel drive started leaking, the cd player went out, the control nobs for the radio cracked and some fell off, the tailgate cables snapped on three separate occasions, once while I was loading an ATV. The tailgate then received a slight dent when it hit the bumper. GM said that their research has shown only the 00 and later models were affected by this. Im thinking apparently not! Its the same exact cable! A year or two later they finally agreed. Throttle sticks starting off, back windows whistle, clear coat started separating and flaking off two years ago. Not enough room to tell it all!

  3-1/2 yrs of performance... - 1999 GMC Sierra 1500
  By Sky King - May 22 - 2:00 am

  Since buying my Sierra new in Alabama, I have lived and worked in Louisiana, New Jersey, and now West Texas. Ive been in mud, sand and water up to the front grill and in 4WD Low the truck is unstoppable! The tow/haul transmission mode is great for pulling the boat. Ive had no mechanical problems whatsoever. The few drawbacks...should have bought the bench seat vs. the buckets- more passenger room and could have sat closer to my girlfriend! Four doors would be better than three. Cruise control accel mode is touchy..tends to downshift the transmission for accelerations at highway speeds. All in all great performance, styling, and durability.

  Love the Z71 but mileage is taking toll - 1999 GMC Sierra 1500
  By gmc2349 - March 31 - 2:50 pm

  Just hit 90k and the repairs are starting to come in fast. Rear end needed to be replaced, along with front diff to be resealed. Transfer case just had to cleaned up from factory flaw. Front wheel bearings went out too all in under 10 months. Thats about $3k in work done. Nothing else out there gets me excited as my Z71 SLT. Great truck, just reliability is becoming an issue at 100k.
