   My husband just did an at home oil change on the car not long before the incident. Unfortunately my car was barely under 3,000 miles since the oil change and we were going to change the oil again when my engine died mid drive on the way home. There was no oil in the car due to high oil consumption and no coolant either. High oil consumption was not reported and not disclosed to me before and a broken guide for my timing chain leading to total engine failure just after I…

They told me the high pressure fuel pump is bad and the piston rings were no good. This was on the 18th of June. I had taken it to…

   It has nothing to do with the headlights. I was told by a couple different technicians that there's an issue with there being a slow oil leak with the GMC Terrains causing the motor/engine to lock up. I get my oil changed religiously! I even have files/reports showing so. It was NOT time for an oil change and my motor locked up. I still have 3 years to pay on my vehicle and it's my primary ride. So after having it towed 4 times...I have to get it towed 1 more time back to…
