SUSPENSION
I have been told by an independent Maine state inspection company that my left front frame rail has perforating corrosion and will not pass inspection. I have not had GMC inspect this yet but I do not think they will repair it. This truck is 10 years old and only has 59,000 miles on it. It looks like new (except for some rear bumper damage) It is unusable now and I'm afraid the left front suspension will collapse. This is completely unacceptable. Please help, Thank you.

STRUCTURE:BODY
I took My 2012 GMC Sierra with 112,410 miles in for annual safety inspection and was told that my frame has a hole in it and is cracked, hence un-inspectable in the state of Vermont. I then took it to a welding shop to get an estimate on repair and the tech told me he sees this all the time on this era GM/Chevy trucks. This is clearly a widespread incident and GM should be held accountable like Toyota was years ago with its bad frames.O

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
An accident has not occurred yet, but it something I'm concerned deeply about. Awhile back there was a recall on the instrument cluster of the gmc Sierra 1500 (possibly othets on the list, im sure). I did wind up having the cluster replaced, there didn't seem to be any issues at the time. Now...the replacement cluster has gone haywire. I notice no issues with operations at this time. But the cluster doesn't register certain things or it fluctuates on and off, or doesn't read correctly at all. Is it possible that the replacement could have been bad as well?

UNKNOWN OR OTHER
I have HD surround vision cameras. I was parallel parking very slowly. The back end of my truck was in so I was watching the camera to see the front right of my truck and the back left of the other vehicle. I could see both vehicles including the road between them. There was space between the vehicles on the camera when I hit the other car. I called Sewell Buick Gmc and explained the camera might need calibrating. They sent a loaner car and picked mine up, When the driver arrived I explained the situation. It surprised his so I said get in my truck and put in reverse to activated the camera and watch me as I walk toward the right front tire. He saw mw as I approached, however, when I got right next to the tire I disappeared from she screen. GM said the vehicle was operating as designed. Operating as designed? They designed a SURROUND camera to show objects until they get next to the vehicle. Imagine if it was a toddler.

ENGINE
When I’m towing my small boat, my temperature gauge starts to rise on my engine and there are no warning lights and it has caused me to have to pull over. I have told the dealership about this. Everyone seem to act like it’s no big deal but when I’m having to pull over, because I’m afraid my motors getting too hot, it’s a problem. And not only that even when I’m not towing anything my temperature gauge keeps going up then back down up and then back down never in my life have I experienced a vehicle doing this

STEERING
NHTSA Campaign Number: 14V246000 Q1- my steering column is faulty and it is on the verge of collapse. Q2- every time I hit a pot hole my truck loses control for a second and it has gotten progressively worse. The car sways from left to right without me moving the steering wheel. Q3- I’ve been having suspension problems that have become worse and worse after being told I’m having suspension problems. I fix what I am suggested too and the problems have worsened. Q4 yes it has been inspected and the issue has been overlooked. Q5 if I try to drive the truck again it will fail, I changed my rotors at the beginning of last month and the two front side rotors have been warped and replaced as of Saturday. I drove my truck just fine until tonight I began losing control of it two times. My brakes are beginning to fail. My brand new rotors have been ruined in less than two days. That’s 4 new rotors in a month. When I arrived at home I opened the hood and applied a very small amount of pressure on the steering columns shaft and it had a lot of play. I added a little more pressure and it moves a lot it felt like I could’ve taken it apart with my hands if I really tried. I’m pretty sure I shouldn’t be able to move the steering column shaft with only my hands if the truck is off.

GM TRANSMISSION CONTROL MODULE # 24256861.... There are over 9,000 GM trucks that are sitting idle because GM quit making this part, There are no after market replacements nationwide. When this part fails it shifts the transmission into 2-3 rd gear and goes into limp mode which if you are doing 70 on the interstate you are in for a sudden awakening. It also causes other issues like stablitrac issues there are at least 4 other issues which make the vehicle undrivable It is sad that GM has known of this failure for well over year. It should be a warranty item but is not. I just need my truck to be drivable again.....

ENGINE
Low coolant warning light came on. I was towing a travel trailer on a very busy roadway with no place to pull off while pulling a trailer. I had to pull over to the shoulder to check the coolant level and make sure I didn’t cause major damage to my engine by letting it overheat. While waiting to let the engine cool down, I researched and found that this is a very common issue with L5P Duramax Engines in GM trucks and it is specifically related to a faulty coolant level sensor. As it turns out, my coolant level was fine and there was no issue. The danger posed by me pulling over and waiting for well over an hour on the side of the busy backroad with my son in the truck was not a necessary one. It appears that this is a well known issue that is not being addressed by GM.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The vehicle is brand new with only 300 miles on the clock. Today while driving to work and listening to XM-radio the volume spiked to max and would not respond to controls to lower volume or turn off. I was able to lower by switching to a different output. It was very detracting and potentially dangerous since the Bose speakers are very loud.
