On October 13, 2023, I was driving on the highway when my 2014 GMC Terrain power was reduced. Suddenly, the engine light came on and car began throttling. Second, an error message appeared on my dashboard indicating -?? engine power is reduced.-?? Then it stopped in the middle of the highway. I was able to restart my vehicle and drove it to a nearby mechanic shop. The mechanic said the problem was my timing chain and that my vehicle was not drivable. I left my vehicle at the mechanic shop because it was the weekend and It needed it to be towed to the dealership. On Monday, October 16, 2023, I had my vehicle towed to Buick Classic Service Center. After waiting for two days, I received a call from the service center stating that my 2014 GMC Terrain timing chain and pressure gas pump was the cause of the problem - with my vehicle. After, reading other owners similar complaints ; why is there not a recall to address this problem? Now, I am stuck without a vehicle and the company has no idea how long it will take to get the parts needed to fix my vehicle. I was told that the timing chain and a tension is on back order due to the employees of GMC being are on strike.

. in October 2019 my car needed to have extensive work done on its timing chains, variable valve timing solenoids, intake variable engine variable timing solenoid, variable valve timing sprocket, heated oxygen sensor, timing cover gasket set, valve cover gasket set, iridium spark plugs, water pump, engine oil filters, synthetic dexos motor oil, coolant. Then in July 2020 the timing chains collapsed on me while I was on my way home from work. The entire engine had to be replaced. My car was completely totaled after the engine collapsed and I was stuck owing 12000 dollars on a useless car.
