Driving down the highway one day around 65mph the vehicle began to shudder violently, reducing my speed to less than 45mph all the way home (all the while still shuddering) I took it to a well known transmission shop "whitty transmissions" in oak ridge NJ only to have them drop the pan and find the transmission flooded with metal chips costing me a $3900+ rebuild. My transmission failed at 87,000 miles

I own a 2014 GMC Sierra and the air conditioning condenser has gone out. This should be a recall since so many GMC & Chevrolet are having the same problem and no help is being offered to us. What a disappointment from GMC. If I would of been notified of this defect I would have never purchased these truck. Now I'm driving around in 110 degrees with my little son. Recall and fix this.

Service 4WD would pop up on my screen everytime I started my truck for the last two days going to work. When I go slow around turns then the truck would almost stop. Found out that it is the actuator and my 4WD is trying to go into 4-low automatically. Dealership could not fit me in for a week, so I took it a transmission place because this is my work truck and now have all my tools in my wife's acadia. I have a 32 ft ladder on my truck that I'm going to need asap and can't put on wife's acadia so I could not wait on the dealership to fit me in. All trans transmission place has had it since 3 pm on July 7th and I just paid $438 for a part and I'm up to three shop hours so far that I have to pay for when I pick it up hopefully tomorrow, which will include the additional shop hours in installing the new actuator. This is getting expensive and there is no recall for this part that I've seen, but should be included in the manufacturer warranty. I can provide all receipts once I get them.

I was driving on the interstate and a message stating "service stabilitrack" message appears simultaneously with the check engine light and service traction control, the car loses the ability to accelerate and maintain speed. I kept driving because there was no safe place to stop, and after a few miles the door locks unlocked then locked, the info screen flashed and then the engine revved and appeared to drive normally. Several miles later it happened again, over and over. When I reached my nieghborhood the car completely powered off.

For over 45K miles I have complained off a vibration coming from the rear of my GMC Sierra at 65 to 75 miles per hour. My supporting dealer that I purchased it from can't find the problem and is most likely out of business.this is an ongoing issue. Recently I went under the truck to find the entire frame is rusted from the gas tank back to the rear off the vehicle around the spare tire and elsewhere. Whats wrong with GM manufacturing, are they that cheap, that no paint is place on the frame. Additionally the chrome wheels that came with the vehicle are corroding yet another cheap process that GM refuses to address. Mind you I have always fixed and repaired my own vehicles. I have washed this vehicle so much by using a cold water hose under the vehicle and the top as well to get the salt and brine used by the northern states off the car and yet I still get the corrosion. How do I get GM. To fix the wrongs they have produced.

I purchased my vehicle brand new in order to avoid unexpected expenses that one sometimes inquire when we purchase a used vehicle. However, the truck has given me nothing but mechanical issues I've head engine power loss problems, have gone through two air conditioner major issues, radiator gone bad, transmission go out and the most recent my roof started to leak. As I did more research I came to discover that I am not the only customer in this predicament there are several others. I'm reaching out to for assistance in regards to these matters, something has to be done GMC has to take responsibility for faulty vehicles if that's is the case. They only give the go around to customers like myself that on top of having a car payment we have to somehow pay high mechanical bills for issues that should not be accruing to new vehicles.
