My 4 cyl. AWD GMC Terrain has had excessive oil use which caused premature failure of the timing chain, loss of power/compression, blown engine, damage to exhaust manifold, cellinoids, and melted the catalytic converter. Its was a road safety, poor emissions due to failed catalytic converter. Headlights are too bright for oncoming traffic at night. Another road & safety hazard. Auto warranty is refusing to cover parts listed above caused by the timing chain and excessive oil consumption problems.

My lift gate has been failing since i bought it used from a local dealership. It's closed down on my mom's leg when she was situating luggage that she'd put in. It has tried closing on myself as well each time i opened it(4×) & when I tried to stop it by pushing up on it, it only forces itself down not up. This is very dangerous & had an old recall from GM motors due to the struts in the lift gate was faulty & made by stabilize whom had numerous lawsuits from other manufacturers due to injuries & deaths. The dealership refuses to fix it for free even though they knew the issue with it cause it was brought to their attention by their detail guy whom had it close on him as well. This a is major issue that needs addressed asap. And not at the expense of the owners but the manufacturers & dealerships that knowingly sell these autos that can be dangerous.

Drive side frame is rotted out which has allowed rear driver side control arm for the wheel to freely move. The passenger side is completely fine. Contacted gm and was told it has to be taken to a dealer to be diagnosed. It-??s easy to see the issue I have pictures that can be provided. This car should not be rotted out frame was perfect 8 years ago with no rust and has been washed twice a week during winter to remove salt with undercarriage car wash.

The timing chain is failing on my 2012 GMC Terrain. It-??s dangerous to drive and it started without warning (to me). It-??s my understanding that this is a common problem with this year and model GMC vehicle as many owners are complaining about the same issue. Will GMC be notified so they can remedy this situation? Many thanks.

The rear tailgate on a 2012 GMC Terrain has auto lift and close. The tailgate opens, but wont stay open then closes hitting you in the head. The heavy tailgate comes down hitting you in the head, and it takes a lot to hold the gate up. I called the dealer who said it could be the power lift. He said there was a previous recall to fix the same issue, but that part is not holding. I spoke with the dealer and found issued on line. No warning lamps or messages appeared.

The left front tire pressure sensor no longer works. My husband bought a newer Chevy and the same sensor no longer works. Friends have the same exact problem with the same sensor on their GMC/Chevy vehicles. Sensor light warns of the sensor not working for the left front tire pressure. Lighted sign on dashboard says "service tire monitor system". when you enter menu and select tire pressure it says left front tire 0. manufacturer defect?

The back gate comes down on your head when you are trying to put things in back or take things out, almost immediately. It has hit my head several times causing immense pain and a migraine. It started in July of 2019 and was slow at first. Now it happens almost immediately.. it has hit my head several times and my son. I saw there were problems with this model with this issue. GMC tells me it is not covered.

Several times in 3 years, the dealership can not duplicate the problem loss of power starts running slow, wont go over 20 mph, check stability light comes on, check engine light starts blinking, acts like misfire or no fuel in vehicle, starts anywhere at any time, very unsafe and scary. At least taken to a certified dealership 7 or 8 times and every time they do something differant, yet the problem persists! the vehicle can be stationary at red light and big or while driving going 45 or 65 and drop to 20 mph and not want to go, I push the gas paddle to floor and it does nothing. This has been intermediate and a problem since month 3 of buying my vehicle. This is not safe and the dealership has basically givin up on me and my vehicle.

My car oil consumption is excessive. I have repetitive codes: P0089, P0300, P0366, P228D, P0014 and the check engine light being on. Car is jerking back and forth when at a stop light. Tapping noise made also. Every 1000-1500 my car is always needing oil (at least 2 quarts) and I also have to put more than the usual amount of gas in it then when I first purchased.

To whom it may concern: Please note that I have observed my vehicle a profound amount of water entering the vehicle somewhere within, at, or in vicinity of the front passenger side of the vehicle and driver's side (front). This occurs during rain-fall. My vehicle began displaying an odor and showing white-yellowish colored matter in the carpet area. The water is now developed into a puddle on the passenger - side and carpet soaked on the driver's side (the lost of footing on the driver's side, makes it sometimes difficult when driving, and shifting my foot from the accelerator to (and) braking (to steer, and performing turning maneuvers). I have researched and noted several consumer chat pages, in which consumers have discussions experiencing the problem of water leaking into their GMC Terrain, and other GMC vehicles.
