FUEL/PROPULSION SYSTEM
I'm having issues with my GMC Terrain when I start it. It always starts but it's like it keeps trying to start or is having issues getting enough fuel to get it to idle normal. Sometimes it only lasts a second or two and other times I have to push the gas pedal to get it to idle normally.

OnStar - I've had OnStar for several years and paid the bill annually by check. The company never sent a renewal bill this year. I contacted them via phone on 1-23-2021, 2-8-2021, 2-22-2021 and 3-9-2021. I used phone numbers 1-866-891-1233, 1-866-579-0028, and the OnStar button to talk to representatives. I also wrote letters to OnStar dated March 9 and March 27, 2021 without results. I had a confirmation # CN4175174. I never received a bill and now the safety device is cut off in my car.

The engine locked up while driving on the interstate rendering it inoperable and undrivable. There were no warning signs (ie. leaks, noises, overheating, etc.). The vehicle now needs an entirely new or used engine and is unrepairable.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The "Service Brake Assist" issue in other 2018 GMC SUVs is happening in the 2018 GMC Terrain, but it is not part of the recall. Our brakes became EXTREMELY difficult to press right as we were turning onto the on ramp of an expressway. Thankfully we were smart enough to pull over and not get on the highway. Had we done so, I may not have been here to type this complaint. The brakes be come extremely difficult to press and that message shows. Dealership is going to charge me $400 to replace a vacuum pump - they were not interested in the information I have around this issue in other GMC SUVs since it isn't a formal recall on the Terrain. I could have died yesterday due to this braking issue. I've owned this car for 3 months.

After starting my vehicle on May 28, 2021, the infotainment screen was pink and green with lines. The radio was playing loudly, and I had not previously set it to that volume. Additionally, the volume control button did not work. I headed to the nearest GM dealer, and I did not attempt to turn off the screen. A service representative said I needed an appointment, and I could not be seen until one day during the next week. I needed the turn-by-turn navigation, and I did not know if the issue would worsen or cause other issues, so I asked for a rental vehicle. My vehicle had accumulated less than 10,000 miles, and I have an extended warranty. I was told the vehicle has to be diagnosed before a rental is approved, and their loaner vehicles were out for two and a half weeks. Every dealership I called stated I could not get an appointment that day. I asked GM to call dealers, and nothing worked. GM said if I rented a vehicle, they would not reimburse me because my vehicle would need to be diagnosed beforehand, with a minimum of a one-day, overnight stay. Normally, the back-up camera takes too long to transition to the radio screen, and it has temporarily appeared black. At less than 300 miles, the vehicle stopped going into drive. That occurred three times, placing me into a dangerous situation the third time, before the selling dealer decided to replace the transmission. At less than 8,000 miles, the driver door switch had to be replaced. I purchased the vehicle with seven accumulated miles. I am still getting familiar with this state, so I need navigation, but it would have caused major safety issues had I attempted to visit family members out-of-state, like I had planned, without turn-by-turn navigation. I had to forgo visiting my family. If more pressing issues had arisen, I would have been completely stranded, over a long weekend, and possibly on a roadside, like before. If I had a family emergency to attend to, the situation would have been horrible.

Car is burning oil excessively and the timing chain is loose putting the vehicle is reduced power mode. The timing chain was replaced at 40,000 miles and now it needs to be replaced again and the car only has 87,000 miles. I bought it with 70,000 miles on it. Someone needs to do a recall on these engines

My Terrain recently started having “excessive” engine oil use. During the last two oil changes the dipstick has not registered any oil. I took it to a GMC dealership, but they only checked oil consumption after 1000 miles and the vehicle is at 121,000 miles currently. I don’t believe it is fair for them to allow an issue of this magnitude to continue, because it wasn’t using 1 qt of oil in 1000 miles, prior to the vehicle reaching 150,000 miles. I have to keep watching the oil levels in order to not damage my engine due to a known issues with the 2012 GMC Terrain. I also have to miss work & drive 30 miles to a dealership in order to have issues documented. I feel like they are just hoping I run out of time & mileage, since the recall is for a certain amount of time.

VISIBILITY/WIPER
On Wednesday, May 19th at approximately 8:30pm I was driving east on I-10 leaving Baton Rouge during a torrential rain storm with family members in my car. As we were driving with the wiper blades on, without warning the driver side wiper blade completely! stopped! It went off to the left and rested on the driver’s rearview mirror. It was such a horrifying shock, I had to lean over to the front passenger side to see out of the window with the help of my sister. I tried to slow down to see if we could get off the interstate or whether or not there was an overpass we could stop under and try to fix the wiper. When we stopped under the first available overpass, I tried to adjust the wiper and played with the on off switch to see if I could get the driver side wiper to work again. It never has worked since yesterday. I decided to stay at a safe distance behind an 18 wheeler using its red lights and trailer width to exit at the nearest offramp where we waited out the rain. When we started out again, we encountered rain again on the Bonnie Carr spillway which was extraordinarily dangerous. I’ve NEVER been so frightened driving in my life as the life. No mechanic, police or insurance have looked at the car. I found that GMC has/had a recall for the 2013 GMC Terrains(in Canada?) but no other year. In a forum I found many other GMC owners who have experienced the same thing but haven’t received any recall information to get the problem fixed. I cannot imagine a more dangerous situation than having your windshield wipers go out doing a major storm in Louisiana. As we are heading into hurricane season this is a crucial issue for me. It is my sincere hope that GMC will contact me and allow me to go somewhere to get these wiper blades fixed or replaced. If I get the wiper blades fixed myself, I would like GMC to confirm in writing that they will reimburse me for the cost. Also, I’m concerned that I could be putting more defect GMC wiper products on my car. Please help.
