Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Model Summary
The Sierra and its Chevrolet Silverado twin are well-rounded pickups with an available full-time 4WD system and generous payload capacity. Ride quality is decent with the Z85 suspension and handling is secure with standard ESC. High-end models have very good interior fit and finish, but all have simple controls. A luxurious Sierra Denali model has permanent AWD and a powerful 6.2-liter V8. The crew cab is roomy with easy access. A six-speed automatic slightly improved fuel economy and acceleration with the tested 5.3-liter V8. We found the hybrid considerably improved fuel economy in our tested Tahoe hybrid. IIHS side-crash-test results are acceptable.

Anonymous, BC (2011 GMC Sierra 1500 SLT 5.3-L V8)

"Rear left leaf spring broke, spread apart and rubbed inner sidewall, vehicle never overloaded and as for as I am concern it should not have broken and of course not covered by power train warranty"

Anonymous, MB (2011 GMC Sierra 1500 SL 4.8-L V8)

"Rear spring hangers and shock absorders had bolts not torqued properly. This caused the lot of noise when driving over rough ground. Dealer could not or would not fix this. Took to independent shop and was fixed in hour. No more problem"

All service has been preformed and dealer twice check the front end during warranty. Went out 9 months out of warranty. I have had far more issues with this GMC than my '98 I drove to 200K. Will shop another brand next time"

What Owners Say

Loose exterior trim or moldings

"Door trim mounding coming loose. Poorly glued"

William M., ME (2011 GMC Sierra 1500 SLE 5.3-L V8)

"This is the third time that the door moldings have become loss or fallen off. Very poor adhesion process. Third is a repeat after prior repair. Started when just out of warranty period. Would just as soon the moldings were not there"

Charles E., TX (2011 GMC Sierra 1500 SLT 6.2-L V8)

"Exterior door trim mid door on all doors separated from door panel. Driver door and passsenger door on drivers side were the worst, double faced tape failed, did not stick well to molding, panels started to fall off"

Chris H., MO (2011 GMC Sierra 1500 SL 5.3-L V8)

"This is my forth GMC truck and the first time that they had stick on Trim. Never in car wash, but 4 times the door trim panels have come loose. First time less just a month after warranty expired. So far all I get is yes it is a design problem and a $500 bill to fix each time. I added aftermarket to my '98, and it was in place and looking great at 225,000 miles and 19 years, when I retired it to a farm last year. Trim is junk and GM will has no fix."

Charles E., TX (2011 GMC Sierra 1500 SLT 6.2-L V8)

"The side molding on this model year is a know problem that GM declined to fix or provide low cost repair for. This truck has had 3 occurances of simply coming off. Each repair is about $500 per door. Finally just left the trim off and stored two panels."

"brake rotors and pads lasted till 89000 miles"

Anonymous, AR (2011 GMC Sierra 1500 WT 4.8-L V8)

"The vehicle needed the front brake system completely replaced by a GM Dealership. I believe this resulted from normal wear and tear, high milage (with no previous problems of any significance), exposure to salted roadways during the eight previous winters since it was new & the fact I park it on a lawn 12/7 (constant moisture)."

Robert C., MA (2011 GMC Sierra 1500 SLT 5.3-L V8)

The same dealer who replaced the oil pressure sensor replaced my steering wheel position sensor. This is my third or 4th Steering wheel position sensor issue. No warranty after 12 months on parts.

"The oil pressue, fell from 'normal' of 40+/- 5 , starting 9 months ago to level in 18-25 range, once warmed up a little. Never had that low. I had a professional service, check and confirm, pressure level. Replaced everying in electrical chain except the gage, which is reading spot on. Nothing changed. Talked to dealer and was told in this model year lower pressure is 'normal' and drop from around 40 to 20 is normal, once engine is warm. Well I have had three GMC trucks, all with same base 350 engine, none even when over 200,000 miles read this low. I don't expect to see the 180-220,000 miles I had from the last two. Very disappointed to point I will go to Ford next time. PS, still waiting for GM to have a seat belt repair kit for the outstanding recall. 'Still not available per dealers.' I Check every 3 months.

Nothing shows as a problem on engine diagnostics, but it cost us about $6800 to get this issue resolved.

Spark plugs or wires failure

"Number 1 spark plug failed. Engine has also been using excessive amounts of oil for some time and may be part of the cause of plug failure. I suspect based on research I’ve done that these problems may be caused by the Active Fuel Management system that GM uses on these vehicles."

What Owners Say

Transmission rebuild or replacement

"At 62,000 miles lost reverse. Pulled and repaired transmission Dealer repaired at reduced rate"

"My major problems began with the engine system that drops from 8 cyl to 4 cyl when cruising. That repair cost us over $6800. We still were having problems and the truck felt at times like we were on a rumble strip. We now needed a new transmission for $5000. These are known problems. In the past my dad and I had a Toyota with a known issue with the frame and they bought it back at 1 1/2 X’s maximum book value. When our truck problems began with the GMC it was within the appropriate mileage to be covered under warranty but not the # of years. Since the internet is filled with cases similar to ours and GMC has since done a redesign to not have a reoccurrence of this issue, we felt they should cover the repairs and they have refused. We have had GMC’s for about 30 years, but without resolution this is our last, but sadly also our most expensive GMC"

Voice control commands

"Learning system is poor at best, as only user for 7 years, it still mixes up commands. Using stored numbers works only when parked or driving slow. Outside noise appears to distort it reception."
