Beaverton GMC did repair work on my vehicle. During the inspection they said they found the radiator leaking from a number of spots and it needed replaced. It has never leaked and did not need replaced. Why did they do it? I as for the parts but they tossed them and would not give them to me.

The timing chain is run by oil pressure. This engine burns so much oil that I have put in 6quarts in 1 month. If not continually checking and adding oil the vehicle stalls in traffic.

SERVICE BRAKES, POWER TRAIN
I received a "service brake assist" message which came on then off. Took the car to a local mechanic who looked it over and said to see dealer as they saw nothing obvious. internet search revealed that many people with terrain said this warning came on when battery was low. Made a service appt for NJ dealer for 12/6/21. on 12/3/21, began a 1200 mile drive from Florida to NJ, after 2 hours, check engine light came on. Took the exit ramp from I 75 and at end of ramp, there was a total braking failure. I had to press very hard to eventually stop. Shut off car, attempted to restart but it would not. Towed to a mechanic who found fluid leakage and a repair bulletin on GM site involving vacuum seal camshaft. #pip5598A diagnostic tip. Internet search reveals many anecdotal instances of same problem. On Monday, 12/6/21, I received an email from GMAC saying that the on board diagnostics had shown a "low battery" concern. The catastrophic loss of braking seems to be connected to a low battery situation. This needs to be looked into by NHTSA.

ENGINE, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
Once again, timing chain incident, this time while driving, wasn't expecting it, suddenly my Terrain steering when became stiff to turn, and happened to realize the car motor had shut off and rolling to the right, nearly hitting parked car. I tried to start vehicle, but made a whining sound, but did not start, yet check engine light was on. I had my OBD reader handy, and got p0011, p0017 codes, which tell me it was the timing chain again in this car. This very dangerous because we could of collided with a parked vehicle, if not for me struggling so hard to steer vehicle while steering wheel was stiff.

ENGINE, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
While pulling out of my driveway the car stalled and the stabilitrak light came on. Car would not start again. Had it towed to dealership because it seemed something electrical was the issue and now they say it needs a complete new engine because it lost oil compression. No oil light has ever come on, no other lights and no oil leaking on our driveway or anywhere else that we’ve noticed. Dealership says they can’t tell us exactly why the engine failed. The car only has 53000 mikes on it. We bought it in august of 2014 and maintain it appropriately

ELECTRICAL SYSTEM
I dropped my son off at school and he mistakenly took my car keys into school with him, and somehow I was able to drive all the way home, 4.5 miles, with no key in the car and no warning to stating the remote wasn't in the car. The issue with this is if I'd driven further, perhaps to another state, or even driven somewhere at night, I would have been stranded once I turned the car off. There was no indication that the remote wasn't in the car, and the car never cut off. I only knew the remote was gone once I arrived home and turned off the ignition. That's when the message displayed that the remote wasn't in the car. I had to call an Uber to go back to my son's school to get the key. This could have been a disaster had I driven further or not had the funds to get back to my son's school. Not to mention if a car thief had someone occupied my car and driven off in it. They could have gotten as far as they wanted (or gas would allow) before the car shut-off as long as they didn't turn off the car. I stopped at stop lights and stop signs and the car just kept going. The issue should be looked into and addressed immediately. This just occurred yesterday. The vehicle has not been inspected and this was the first time anything like that has happened. I normally receive a warning message if my remote isn't in the car even if it's just in the house. This is clearly a defect that needs to be fixed.

ELECTRICAL SYSTEM, STRUCTURE:BODY
The failure point was the seal on the sunroof and the sunroof itself. A correct failure mode would be for it to leak into the cabin thus being immediately visable. Instead, an internal seal apparently failed allowing the intruding water to flow unobserved into the bulkhead region between the car body and the internal liner of the vehicle. As a consequence it flowed down a side post exiting into the dashboard and control panel. The dashboard shorted out elliminating the turn signal indicator (and possibly the turn signal itself). The radio and amplifier and the general alarm system went to maximum volume. Fortunately, it did not short out the airbag, thus it did not deploy while I was on the freeway, maybe next time. The salient point is that water was allowed to intrude through the sunroof and able to proceed unobserved to the back of the dashboard. The inside of the car was removed and replaced as was the major components behind the dashboard. The airbags were not replaced.

STEERING, WHEELS, UNKNOWN OR OTHER
While driving, the traction control light turns on. Then the gauges all start fluctuation. The dash reads service park assist. Then service stabilitrak. It does not run properly. It shifts hard. I’ve had it to the dealership twice now. The issue is still not resolved and it’s going back next Monday. I feel it will again not be resolved after reading multiple forums of others having the same issue after spending thousands of dollars. This is frightening and stressful to say the least. My car has less then sixty thousand miles on it. I should not be having this issue.

ENGINE, POWER TRAIN
I bought my 2010 GMC Terrain SLE at 160,000. It had a rough start up but the dealer said it was because it was an older car and been sitting for a while. The rough start up never stopped even after replacing the catalytic converter because of code P0420. The mechanic informed of this specific vehicle oil composition so I was consistently checking the oil. A month after the NEW catalytic converter was installed. I stalled out on the interstate with traffic going 65 mph minimum, the wheel locked and I was almost rear ended. I take the vehicle to an automotive shop and I need a new timing chain with numerous new codes. P0325 P0326 P0327 P0016 P0017 P0014.
