My car wouldn-??t start, later found out it was due to timing chain issue which ended up blowing up my engine. I live 40 minutes from work and am consistently driving on the interstate for at least an hour a day. GM said there-??s nothing they can do even though there-??s been class action lawsuits for the engine. My car has also had oil consumption problems. I bought my car in March of 2022. The engine blew up by November 2022. I barely got my car back in September 2023. After the engine replacement, still wouldn-??t turn on, over heated immediately when I did get it back. After paying $7440 for the engine replacement I had to fork over snother $650 to replace the fuel pump control module, and an engine control unit. My car overheated AGAIN just 2 weeks ago!!!!

I spoke with car lot to whom I'm making payments with and not able to get anything done with the vehicle.

I purchased the vehicle in March 2018. From the date of purchase, the service engine and/or change oil lights would turn on. Every time I took the vehicle to my mechanic, it needed oil. In January 2020, I got a notice from GMC about the settlement of a lawsuit regarding vehicle oil consumption. I took the vehicle to my local GMC and the manager read the "notice of approval of class action settlement and claim form" that was sent to me. The lawsuit requires GMC to pay for repairs or reimburse customers for the repairs. My vehicle had not had the necessary repairs done to it, so the manager instructed me to approve the necessary repairs and pay for them out of pocket because GMC would reimburse me. The repairs were completed on February 7, 2020. I followed all the guidelines provided to me by GMC in order to get the reimbursement. I mailed documents to them a week after the repairs were completed, months before the deadline of May 16, 2020. After waiting over a month and not getting reimbursed, I called GMC customer services (1-866-790-5600) on April 11, 2020. I was informed by GMC customer service to expect a reimbursement check for repairs and rental car fees within two weeks. After not receiving the reimbursement, I called again in June and July 2020 and given the same information-wait. This continued throughout the summer. The delay was blamed on covid-19. I called again in late September 2020, and they instructed me to email all the documents and that the check would arrive in two weeks. On September 30, 2020, I emailed all the documents to GMC. After waiting another two weeks, I called them and they again said it would come in two weeks. On November 10, 2020, I sent another email asking for the reimbursement check. A week later, I got a letter stating I did not qualify for reimbursement because the time had passed/expired.

The vehicle going through oil like made and stalling in the middle of intersections or pulling onto a road. This has caused other people to almost hit me or go off the road to avoid an accident. I will start out into an intersection get in the middle and it dies. Turning onto a different road this happens also in motion going at normal speeds for the road.

When refueling vehicle at a gas station, at a full stop, with the engine turned off, the gasoline pump will not stay on while inserted into the fuel tank of my 2011 GMC Terrain, no matter which fuel vendor I buy a fill up from. I have had this car for several years, and it has never worked properly. I decided to reach out to see if this is a normal issue for this vehicle. If it is not, then could this be a recall event? thanks for your helpfulness.

When inserting the gasoline pump's nozzle to refuel the vehicle, the nozzle does not lock into place during the pumping of gasoline. Vehicle owner has to manually hold the fuel dispenser's handle to refuel their vehicle during the entire 16 gallon operation. There appears to be a part missing that would control the safe automatic refueling of this vehicle, but that part is not on my vehicle.

Significant exhaust fumes accumulating inside passenger cabin during idle/stop. Volume of gases smell less while in motion but still evident. Significant reduction in engine power noticable; as well as erratic noise from the engine and extemely hesitant acceleration response.

My car shut off once while I was in idle at a red light and second time when I was backing up into a parking spot some one who was driving opposite me could have hit me when the car abruptly stopped. Luckily they were going very slow and stopped when my car stopped. The engine shuts off as well as the lights on the dash but when you put it in park and start it up again the engine starts back up and no check engine lights appear. Can you please look into this?

My GMC Terrain 2011 is having trouble accelerating, and I hear a noise from the engine. When I am at a stop light and I try to accelerate, it pulls and doesn't go forward. It's stalking my Terrain. I did some research, and I found that this vehicle has a recall #12313D- special coverage adjustment- engine balance chain and fuel pump. I looked up, and it seems this vehicle has 0 unclaimed recalls. So, I'm concern because this vehicle is stalling and not working as it should be. The recall does say, 'if left untreated, could cause the chain to break, leading to engine damaged.

Fuel pump problems. Misfiring and shutting off.

The car was taken into steven lust automotive and we were told that a transfer seal needed to be replaced and that GMC was aware of the issue but would only warranty the issue if the car was produced in a certain factory. Same year same model all having same issue but produced in a different plant. Now the stabililtrac warning comes on and from research on the web this is a common issue that they are aware of also but refuse to fix. This car only has 66000 miles on it. We also contacted GMC and they told us that they are aware of the problem but will not warranty it unless is was produced at a certain factory. When the stabilitrac warning was noted I was driving down the highway and the engine just shut down. I do believe this issue is due to the excessive oil leak coming from the seal. This is the second time that I have placed this complaint. When I called to confirm that I placed the complaint no one could find it.

Fuel pump failure allowing gasoline into crankcase in large volumes. Rough idle, constant stalling, misfiring, fuel smell recirculating into cabin. Exact issue addressed by GM recall for my exact Terrain and equivalent Chevy equinox with 2.4 ecotec. Was told mine was not covered as it wasn't in correct VIN range though same make, model, year, motor, highly dangerous combustible issue matched. Dealer charged me $700+ for replacement/repair of fuel pump, both O2 sensors, fuel line, oil change to rid gas diluted oil. 2 days, 50 miles later, O2 code engine light comes on, erratic idling begins, power loss then stalls. Removed oil cap to smell and find gasoline mixed back into oil. Between 1/8 - 1/4 quart gasoline in the crankcase after 50 miles of driving! this after "repair" at "certified" Chevy dealership; a dangerous manufacturing flaw GM acknowledged was a problem but I was told, " not on yours though, wrong VIN". thank you for placing my loved ones in danger GM, refusing to fix your own recall, charging me over$700 to worsen the issue and place my family in greater danger.

While driving down a busy two lane road I pulled out into an intersection in an attempt to make a left hand turn when the car stalled in the middle of traffic. I turned the car off and turned it back on again and it worked. However, later that day it stalled again while it was sitting at an intersection. I brought it to the dealership for repair and they said it was not covered under warranty even though I still had one. They said there was a fuel leak at the fuel composition sensor. They replaced the sensor. GM extended special coverage # 17097 in May 1, 2017 for 2011-2013 Chevy equinox and GMC Terrains that are equipped with flex fuel due to a fuel leak at the fuel composition sensor but they did not include my 2011 model Terrain that is not equipped with flex fuel but it should have been. This issue was out of my control as it was a manufacturing defect in the fact that they placed the composition sensor below the frame exposing it to damage from road debris.
