What 2011 GMC Sierra Denali owners say
Most recent owner complaints, unedited.
I have a issue with my dashboard cracking along the airbag module door. I believe if I was or involved in a accident and the air bags are deployed the pieces of dash can become fragments and cause excessive injury and also could deflate the airbags upon expansion. Causing more injury than deem necessary.
Dashboard cracked at corner of passenger airbag. December 22, 2020. The vehicle was in the garage. I noticed it as soon as I got in to drive it.
Hit a deer while driving, airbags did not deploy but made a noise and sounds liked gas was released. Like the airbags tried to deploy but didn't. Now my airbag light is on and says to check airbag system or something to that effect.
The right side dah panel is cracked at the top left corner of the passenger air bag..
Dash has been cracked completely through on passenger side by airbag, now I have a crack just above instrument cluster. Vehicle only has 47,000 miles and the cracks just appear out of no where. The vehicle is not driven off roading or anything like that it is immaculate other then now cracked up dash. It's never been in an accident.
In 2017 before my vehicle completing two years from the date of purchase at (70,000 km) the vehicle start shuddering when accelerating at low speed, when the service was due I took the vehicle to dealer for service & complained about the shuddering issue, after diagnosing the vehicle they said that they have to replace the torque converter, so they did replace the torque converter under warranty after fixing the torque converter issue I found trace of oil in front driver side & again when the service was due I complained about the leak, after diagnosing the found that the shock absorber is leaking, but they didn't replace it because it's not covered by the warranty as they said it's considered as consumable parts, very strange for a shock to leak in less than three years considering that I didn't even drive it in offf road, & this is not the first vehicle I own, all the vehicles I owned didn't leak for twenty years, sorry I know it's consumable part but I am not convinced by these words, there must be a problem with the shocks, anyway I decided to not replace it with the oem shocks I installed four new after market shock, no more problems with the shocks till today. In q4 last year 2019 the transmission shuddering issue started again & when I took the vehicle for service I raised a complain again for shuddering issue, this time they said we don't have to replace the torque converter we only have to flush the transmission fluid with new oil, I think it's mobil 1, & I have to pay for that because again consumables & not covered by the warranty, hey wait a minute yes I brought the vehicle for service plus the shuddering problem but the transmission fluid is not due yet for change if you have to flush the transmission to fix the problem then do it, but don't charge me because of the manufacturer fault.
Dashboard cracking in 2 places.
I opened up the door to my gmc sierra and noticed there was a crack above the air bag and from the defrost vent to the middle of the gauge cluster cover on my dash.
Takata recall my vehicle is affected by this recall I have called numerous dealerships and they all tell me gm don't have a fix yet so because of this issue does this mean my vehicle falls under lemon law since it's 8 years old and the problem can't be fixed thanks takata I love my denali
