When I drive my vehicle on flat surfaces and even going up hill, I will get a large cluncking sound from my vehicle. It seems to happen when on a delay shift or when the vehicles weight shifts. I have brought my issue up to GMC while under warranty with no resolution. Please assist. Thanks

I noticed headlights not working low or high beam. LED lights around head lights worked and fog lights but no headlights. I normally keep it on auto, but I tried all positions and none of them worked.

Head lights quit working. I had two children in the car with me and it was night time, and I could’ve collided with another car. This just happened tonight, so I have not taken it to the dealer yet or a certified mechanic. There were no warnings of any kind before this happened.

Steering completely stopped, couldnt steer vehicle while I was driving on HWY with 6 High School Football players inside coming back from a scrimmage. All of Our safety was put at the utmost risk, as we were traveling at HWY speed of 65 and had to maneuver in between traffic to get the vehicle off the road without being hit by oncoming traffic at high speeds. We dodged several accidents during this incident. Let alone putting the lives of the 7 of us and several others on the road. Problem has been declared by a professional Auto Diagnostics Dealer in town, as my vehicle is at, diagnosis is failure of steering rack and pinion, which caused the replacement of powersteering pump, hoses, serpantine belt and reservoir replacement. So far.... The vehicle did not give any signs, signals, or any noises were heard to let us know that there was any failure issues regarding this dangerous incident.

My left rear turn signal is not working. It is GM part number 13582912. I have checked with several GM dealers who have. Confirmed there are none available. Just for the sake of it, 3 dealers have it on order but have no confirmed delivery date. Some parts stores say it’s is discontinued. There are no other aftermarket parts to substitute. This is a significant safety issue the GM needs to correct.

First problem is the trunk door. About a week ago I was getting something out of my trunk and accidently hit the button and the door started to close so i tried to get away from it and somehow my arm got caught and there is absolutly NO sensor to stop the trunk from crushing my arm. Unforunately, i did have some injury to my arm from the trunk coming down and have pictures of the brusing on my arm. A sensor to stop the trunk from closing on a body part or anything for that matter needs to be better made or put in the vehicle. I took pictures of my arm days later because i was in to much pain to take them when it happened. It was not a fun injurying. Saturday night iced it, sunday had to have it elevated because it was so swollen, didnt take the picture until Wednesday when it finally had calmed down. There is bruising and swelling still on Wednesday. this happened July 9th Second problem i recently had an issue with my wiring i guess it was. Specifically it was reduced engine power message displayed and my engine stalled out on me. I was told that this is a common problem with Buick Enclaves, Chevrolet Traverses, and GMC Acadia's which is the car i have. Being that this is a common issue wouldnt this be something that would be concerned a RECALL? i dont know how recalls so im more curious about it. my car stalled out on me in the middle of traffic on July 16th

My air bag service light is on when a passenger sits in it. Looking at others complaints this is a normal thing for GMC 2014 Acadia. I am wondering why a recall has not been done. I just bought this car 3 months ago and they are quoting me $600, stating it is not under recall list as it is not my curtain side air bag. Looking at others complaints- they have to have it repaired many times. This should be a recall!

NHTSA ODI 11465487

Thinking it’s possibly the front passenger air bag isn’t working properly. The Air Bag light will go on and off for no apparent reason while someone is or isn’t in the seat. Makes me scared for anyone who is to sit in the front passenger seat; knowing that there’s possibly a danger issue.

NHTSA ODI 11463382

Service Airbag light is on. Diagnostic code states it’s the wiring harness under the passenger seat causing an AMP draw. Mechanic told me there is a safety recall but I’m not seeing one for this issue, however I do see a lot of other complaints for this same issue. This is a safety issue and should be addressed.

I was involved in an accident on 03/31/2022 I was only passenger. Going about 35 mph hit a parked vehicle on passenger side of vehicle. Side air bags employed. But front air bags did not. I did get a concussion and left with scar from embrasion above right eyebrow from hitting steering wheel. Why did not the front air bag go out?

NHTSA ODI 11460307

I was driving down the road 55 mph and my acadia stalled. Then stabiltrac and traction control turn off then it goes to half power. So then i have to pull over wait a few minutes and restart it. This happens everyday and im nervous to see even drive my truck and it is a safety risk as it could cause a accident. I also read on the internet that it has affected multiple years and models so im not sure why there is no recall

Gas gauge does not read accurately. We have ran out of gas one time due to this issue, resulting with us stalling in the middle of a busy street. Now that that has occurred gas is put into the tank every few days but gas gauge still only registers 1/4 of tank to “Low Range”. MULTIPLE OCCASIONS!

Twice in the past six months, the “Service Air Bag” warning light has come on. The first time, the wiring under the front passenger had to be resodered. Last week, the same warning came back on, and the wiring under both front seats had to be resodered. I feel this is a safety issue, and a design failure in this year and model car.

NHTSA ODI 11453201

When I turn a corner and accelerate, the vehicle jerks as if the transmission is slipping. I called Gmc and made an complaint. My vehicle has just over 50,000 miles on it. Very concerning

2017 blind spot detection lights on in both mirrors. Both modules in rear bumber replaced. 2021 blind spot sensors on again and “park assist off” in DIC with system not letting me turn back on.

NHTSA ODI 11448134

Service airbag light has been on since I’ve had the car. It was not covered by warranty (even though it is important?) in order to fix it I was quoted over $1000 which is ridiculous as I only had it a month before that and traction control became a issue. Warranty covered the traction but not the airbags.
