Timing chain/belt. SUV is making a loud rattle when turning vehicle on. I got this issue "fixed" last yea right at 79,000 miles. Warranty paid for it. 20,000 miles late I am having the same issue again, rattle noise, engine light on, air bag light is on. It worries that this will be a major if it gives out while I am driving with my kids.
Since the day I drove my Acadia off the lot there has been a "click" that occurs which sounds like it is coming from the engine that can be felt under the gas pedal when the vehicle is about to shift into 2nd gear, but only immediately after starting the vehicle and never again when switching between 1st and 2nd gear until it has been turned off and restarted. The noise it makes sounds like a marble rolling on a wooden floor for about 1-2 seconds and then click and then the gear shifts. The dealer said they didn't hear anything but I do as well as other passengers do every day. Additionally, when turning the vehicle at a slow rate of speed and then accelerating, the engine slams into gear when between 10-15 mph but only after a turn and an attempt at acceleration. Also, my Acadia is not a vehicle under the "faulty gas gauge" recall however once my vehicle is below 1/4 tank the needle on the gas gauge will jump from 1/8 tank to 1/16, back up to 1/8 of a tank all while driving on flat roadways. Concurrently, the range for the fuel on the digital screen goes from 95 to 58 to 72 all while driving with cruise control on at a consistent speed. Lastly, the vehicle has the denali grill which leaves minimal airflow from the engine compartment. Up to three hours after turning the vehicle off (in a cool garage) you can still feel the heat coming from the engine compartment if you place your hand in front of the grill. Could this be a possible fire hazard? all of these issues began when I purchased the vehicle with 60 miles on it and continue now at 15,500 miles. I drive frequently and can tell you that I do not feel safe in my vehicle but am unsure what to do as the dealer has told me there is nothing wrong with it. The only recall for my vehicle is the seatbelt issue but I think there are serious engine problems with this vehicle that need to be addressed by gm.
