Overall I am well satisfied with my truck. I have the American touring package. It has a large motor in it which means I cannot afford gasoline to drive it every day.

The truck that I drive is a good truck to get you from one place to another but the gas mileage is awful and it makes weird noises sometimes. I have had to replace many things on the vehicle such as the alternator and catalytic converters and serpentine belt.

Reliable but a gas hog and not much get up and go. It does make me feel safe and 4 wheel drive is a must in Minnesota. It is a decent looking truck and it is nice and spacious for hauling dogs and kids around in. The bucket seats do really hurt my bad back so I sit on a pillow.

What Do Critics Say About the Sierra?

  • Consumer Reports says the Sierra is comfortable, but owner satisfaction is lower than its rivals.
  • Edmunds gives the Sierra a 4.2/5 liking the spacious cabin, but disliking the cheap interior materials.
  • Kelley Blue Book users rate the Sierra 4.6/5 and enjoy the high towing capacity, but don’t like the rust issues.

What Common Problems Does the 2006 GMC Sierra 1500 Have?

Problems with the 2006 Sierra 1500 include rusted brake lines, slipping transmissions, and fuel gauge issues.

Rusted brake lines are the most common complaint from owners, showing up at around 100,000 miles. The steel lines get corroded in areas with a lot of salt, costing around $1,000 to replace.

Transmissions slipping out of gear are brought up by owners at roughly 75,000 miles. Usually it’s a sign of a problem with the third and fourth gears in the transmission, which cost around $500 to replace.

Fuel gauge failures are a problem that shows up on many GM vehicles in the first 90,000 miles. The fuel sending unit in the tank doesn’t send the information properly to the gauge, and costs about $850 to replace.

There are 11 mostly minor recalls, with the most serious being for the power steering hose, which can break and cause a loss of power steering.

How Long Will the 2006 GMC Sierra 1500 Last?

A properly maintained 2006 Sierra 1500 series should last over 250,000 miles, about 50,000 miles shorter than the Ford F-150. Regular annual maintenance costs are similar to other trucks around $480 per year, according to Repair Pal.

Most Sierra models from 2006 will have over 100,000 miles so buyers should be prepared to replace the air conditioning evaporator for $1,400, axle shaft seals costing $400, and control arms which cost $500.

accountCircle Traci Z

It is very reliable. I haven't had any major problems since owning it besides the normal wear and tear. I would buy this truck again if I were looking for a truck.

accountCircle Josh W

I have put a rack and pinion on it. That is been the major repair on the vehicle so far. Everything else has resulted from age. I replaced the abs system on it, only because the previous line system had rust damage.

How Much Is the 2006 GMC Sierra 1500 Worth?

Blue book values range from $5,225 – $12,775, making the Sierra about $2,000 cheaper than the Chevy Silverado 1500 and Toyota Tundra. When new, the price range was $15,840 to $38,775. Depreciation is average for a large tuck losing about 7% of its current value per year.

What Colors Does the Sierra Come In?

How Big Is the Sierra?

The 2006 Sierra 1500 series is a half-ton truck similar in size to the Dodge Ram 1500 or the Nissan Titan. There are three cab sizes, a 2-door regular cab, 4-door extended cab, and larger 4-door crew cab. Passenger space is good in the crew cab model, but cramped in the others.

Three bed lengths are available as well, including a 5-foot-8-inch short bed, 6-foot-6-inch standard bed, and 8-foot long bed.

How Does the Sierra Compare to the Competition?

The Chevy Silverado 1500 series is a close competitor, costing about $2,000 more. Both trucks are built on the same platform and share the same engines and transmissions. We recommend the Sierra since it has a nicer interior and is more affordable.

The Toyota Tundra is another rival, which costs roughly $2,000 more. Where the Tundra stands out is with better long-term reliability ratings, but the Sierra has a higher towing capacity. We recommend the Tundra since it will last longer as a used truck.

6 l. Motor large cab pick up truck.
I have a 2006 GMC Denali sierra 1500, it is a 4 door pick up truck with a full cab with a center console. The seats are heated in the front seats, there are 3 levels of heating and a separate heat button for the top seat heater. The pickup has a wonderful trim package that is black and gray wood grain details. There are plenty of cargo/ space in the center console along with a 12 volt charge along with the cigarette lighter in dash and a 12 volt in the dash. The side view mirrors have the turn signals inside they also have power close option with the backup tilt which is nice to have. The ride is great on the car it is a 6 liter motor and has over 120, 000 miles and it is still full of get up and go. The gas mileage is about 15 miles a gallon. The rear window defrosters work great. The windshield washer hose broke but other then that the headliner dropping are the only issues we have had with the pick up, I highly recommend a the 6l 1500 GMC Denali.

An interesting detail about my truck is she never broke down.
My truck is a GMC sierra. I named her betty. My truck performs well in all kinds of weather. The only problem I have is with my tires and for an old truck she moves pretty fast. Before I had a problem with the ac in my truck but I got that fixed. With cleaning and respecting my truck rules she performs amazingly. She moves fast and everything is in working condition. My rule for all those who own vehicles is that if you respect your vehicle and the road, the vehicle will perform phenomenally.
