Engine Belts And Pulleys problems of the 2012 GMC Terrain

2012 GMC Terrain makes a clicking noise when pressing acceleration pedal. I habe changed oil, plugs and belts but still can't find source of tapping. Also my tires are new, less then a year and constantly show low pressure. I have checked for nails but none found.

I also have a 2012 GMC Terrain that has an oil consumption issue that has caused complete engine failure. Approximately 2. 5 weeks ago the car wouldnt start. Engine would turn over but not start. I thought that it might be the fuel pump. Had it towed to my mechanic since it has 87k miles and out of warranty. So I went to check the status of the car and the first thing I was told was there was no oil when they checked it. They added 4 quarts before trying to diagnose the problem. Mind you the oil was changed 3k miles ago and oil life monitor said it had 54% life left. They ran the car for codes and the only code that came up was for the tire pressure system, also an issue with the Terrain. No issue was found with fuel pump or sensors. Spark plugs were replaced due to them being all fouled up. That didnt fix the issue so it was determined that it must be the timing chain jumped. At that point I had it towed again to the dealership I purchase it from. I was told it would be 125. 00 to run a diagnostic. Fine. So I get a call the next day that it was indeed the timing chain. I asked the service guy what would cause this and I was told poor lubrication or low oil pressure. Thats when I started to explain that the first shop had to put 4qts of oil in bc it was bone dry. I asked about the VIN specific letter I received last year,2017, about the oil consumption issue and isnt that why there was no oil and hence causing the timing belt to jump. He answered "no". Then told that upon further inspection, the valves were bent so we were now looking at 3500 to fix or 6k to replace the engine with another problemed engine. So that is when I contacted the toll free customer service line about the situation. They told me to go back to dealership and speak to the customer experience manager.

Timing belt stretched and jumped. Cylinder head broken. Timing belt jumped while driving, began making a very loud rattling noise.

Car started making rattling noise on startup. Got worse. Took to a few car places and thought it was the oil. But the oil was fine. Then the engine light came on and a second later the car shut off while I was diving down the road with my two babies!! very dangerous! ran into a friend who has the same make and model car as mine and said she had the exact same problems. Has 80k miles and has already changed the timing belt five times. Car just shuts off. Extremely dangerous! I will report this to everyone I know and warn them.

I purchased my 2012 GMC Terrain from clay cooley in irving, TX on 01/05/2015 with an extended service contract. I have had issues with this vehicle ever since. I took the vehicle in for service and was told the service contract would not cover my issue and that the issue was caused by lack of maintenance, which is not the case as I maintain the oil in this vehicle and even had to purchase a new battery for the vehicle recently. I am attaching a picture of the condition of the battery shortly after the vehicle was sold to me to where I contacted my sales agent and he advised me to check my service contract. This car¿s engine repeatedly stops, especially when approaching a red light or stop sign or at the moment of acceleration. I have had to avoid many accidents due to people driving up on me because I should have been accelerating at the time but my car turned off. The battery would die on this car on a weekly basis which caused me to purchase a battery and there is still no progress in the vehicle. There are electrical issues as well as the lighting in the car gets dim when we are in the dark but bright when the sun is out. Also, the seatbelt for the passenger¿s side constantly rings sending a notification that the seatbelt needs to be latched, even when no one else or nothing else is in that seat. I fear that one day I may need that air bag and it might not work because the seatbelt appears to be faulty. Also, another issue, which is not necessarily a safety issue, but an extreme nuisance and also maybe an electrical issue is the car radio and volume will freeze at any given moment and the car has to be stopped and idle for a period of time before the radio is active and able to turn channels again. The safety issues for this car is real and I am in fear that I will get hit from behind due to the faulty engine.

The motor knocks badly upon startup, especially in the mornings. The engine is very weak after an independent diagnostic check. And just last week, as I was driving on the highway at normal speeds, the muffler shield broke, fell, and began scraping against the highway.
