2011 GMC Acadia: won't start

Filed Oct 16, 2020 · Engine · 138,706 miles · PA

Was driving my car. Got off I-79 to get gas. Got back in my car and it wouldn't start. Had to get a jump. It started. Started driving (about 4 miles) all of a sudden it started making a noise from the motor. It never gave me a warning, no noise or anything before this. It ran perfectly. I'm so disgusted. They're saying almost $5000.00 with parts and labor with a used motor. The bearing spun, the roller rocker broke off timing chain, and something else. Hmm a used motor. You do know a used motor will fall into that category again!! I took it to the mechanic where it still sits. I upkept the oil before it was due. It has 138,706 miles I never had any problems with this car at all . Gm I hope you do us right because we stood by you and trusted you!

This all began at about 75000 miles. It first started with the stabilization/traction light coming on while driving once this happened you could not accelerate the car. I once was on a highway in the middle lane when it happened I could not accelerate and had to try to get over to the break down lane. This happened several times but then turned into a completely different problem. While driving the battery would start to die with no warning. When this happens you can not jump the car you have to bring the battery to be charged on a charger. Although the car won't start the other things like lights, radio, etc will still work. This happened several times but once the weather was warm it ran perfect for 4 months. The first day it was extremely cold the battery died while driving. I also had a headlight go out on the drivers side and about 3 weeks later it came back on and stayed on. I have brought it to several places but nobody has been able to figure out the problem. I can't keep spending money to get it diagnosed with no results. After researching online it seems to be a very common problem in the acadia.

Stabilitrak always reports off and brake warning always displays on dashboard, while on or running. Had it looked at by 4 mechanics. Breaks are fine. Engine wont start after everytime I pump gas. I have to pump accelerator sevral times for engine to start. Had it looked at again. Problem is ongoing. Also, slowed down on one occasion while driving on the hwy. Had to pull over since accelerator would not function. After 30mins or so. Was able to restart.

2011 acadia denali, has hid headlights for night time driving, and traditional incandescent lights for daytime running lights (drl). I noticed the driver's side drl bulb was burned out approximately a week ago (so ~5/12/2019), when I when to remove it to see what size bulb was needed part of the projector housing broke off with the bulb. I then noticed that the bulb socket was partially melted, and the dust seal around the bulb is also partially melted (brown and starting to melt). I also looked at the passengers side and, without removing the bulb, you can see that the projector housing on that side is also starting to bubble/melt. The drivers side bulb is melted enough that I cannot remove the entire bulb from the socket, only the glass wants to pull free. I feel lucky it didn't start a fire.

I was driving my 2011 gmc acadia and all of a sudden the car started to decelerate. I pulled over and turn the car off and then the car would not start again. I had it towed to the dealership. The dealership is saying there is an issue with the timing chain. The dealership said that the timing chain failed. Upon doing research, I see that this is a common issue with gmc models, especially the acadia model. The dealership is saying that the repair is going to cost me $7500. Given that this is well-known issue with the acadia model, I feel that this issue should be recalled for the safety of consumers.

My 2011 gmc acadia would not start one morning. We put a battery charger on it. It started but has a pinging sound. We checked the oil. The oil was reading low. We added 3 qts of oil. We had auto repair shop change oil and install new battery. I still noticed the pinging sound. That evening, as I was driving the engine started making terrible sounds and loosing power. I stopped driving and had it towed to dealer. They said the engine was blown. I had no warning lights come on at all. The dealer is telling me it is most likely the timing chain. The acadia is only 5 yrs old with 116k miles. This should not be happening to this new of car. I have spoken to several mechanics and they all say this is a known issue with the acadia and this should be a recall or warranty issue. Equally frustrating, I bought a warranty that I was told was an "extended warranty" that I thought would lover it now I'm being told the warranty was from the date of purchase which is not what the salesmen told me when I bought it. I feel totally taken advantage of as a women.

For two weeks leading up to the 3/27/14 incident, every time we started the car the air would not come on and we would have to manually turn the air on. When we turned the car off, the air would stay on. Two weeks later, when I was operating the vehicle, the gauges on the instrument panel started going haywire displaying dozens of messages, and the all of the gauges would shoot up, then bottom out at 0, then shoot up again, etc.. I turned the car off, and when I came back later to start it, the car wouldn't start but the electrical stuff came on. After several attempts to get the car to start, I roll down my windows and then try it again, and the car started. I drove it straight to the dealership. The dealership replaced the body control module and some wires and said they fixed the problem. Less than 48 hours later, the same thing with the gauges and warning lights happened. We immediately sent an email to the service department since it was the weekend and they were closed. On monday, the car died again, but the radio kept coming on/off....I fiddled with the radio and the car started. I drove it straight to the dealership. They can't get the car to "mess up" again, and are waiting for it to do the same thing it did for me, so they can figure out how to fix it. I am concerned that the car is showing significant electrical problems that include safety equipment, yet gmc is ready to turn the car back on the road. Note: all recalls are up to date and the dealer has been in communication with gmc.
