After having for just under a year the transmission seems to be acting up when going from 2nd to 3rd gear around 30mph to 40mph. After reading several forms it seems this is a common occurrence in these vehicles.. not sure if it-€™s been reported but all the forms are showing people had to spend a good amount to determine what the issue is and seems that everyone had to replace the transmissions for the problem to go away. I-€™m not sure how everything works but feel it should be looked at maybe.

When driving in traffic and slowing down or coming to a stop. The vehicle goes completely dead. I will have to restart at each stop. When it does start, it is not a smooth take off, it is extremely rough, almost like a manual transmission in the wrong gear. This should not be happening. And it is getting worst every day. I have to Transport my family in this vehicle and it is very unsafe for us. I still have a year to pay for it and I am hearing more and more customers with the same complaint. The dealer doesn't want to touch it, because they are unsure what is wrong, or if they can repair it. Frankly, this should not be an issue with this many cars. There have been several near-misses with accidents because of the car stalling in traffic.

I have never had to replace bulbs in the headlights in a vehicle I have owned. The headlights in this vehicle were good about 2 years. But, since then I have had to replace both bulbs in the headlights every year. And, I have to have the A/C system worked on every year as well beginning 3 months after I purchased it. Purchasing this vehicle is the worst decision I have ever made in my life. I am constantly having something break. Headlights, wheel bearings, motor mount, multiple issues with A/C, transmission.

Piston connector rod put a whole in the engine at only 62700 (2700 miles after oil change that was always changed after oil change light came on around every 4500 to 5000 miles)miles on the vehicle. We were driving at 70 mph on major highway and suddenly stop responding and would not start in an area that only had half of emergency lane(so the car was taking part of travel lanes).this was December 27,2018 at 11:30 pm with me, my wife, our 2 kids, our nephew and their friend (8, 12,13 and 14 years old) we were coming back from a ski trip 1 and half hour from home, it happened about 40 minutes away from home.we could not come out the car, it was not safe place out of the car. State police drove by and did not stop, I called then to send someone until tow truck come.tow truck came first after around 45 minutes.car computer cluster start to show battery was dying, it was pit black with 18 wheeler and cars flying by. This is a safety issue - drivers with families should be made aware.I went to the local GMC dealer to ask why it happened since car has 62700 miles and they ask me if my wife does off road I said no.but I asked my wife to make sure she said no.but to make double and triple sure I asked my 8 years old daughter and my 12 years old if their mother drives on mud, water, bump hills, wet land, shaking places and pot holes. They said no but that would be fun (lol). Thank you GMC for a nice holiday gift.

These symptoms started over 2 years ago and is very intermittent. Driving on the highway, the vehicle suddenly loses power, unable to accelerate and the transmission will not shift out of high gear. The decrease in speed is significant enough that on now 3 occasions the vehicle has almost nearly been rear-ended. Additionally, on the instrument panel the following indicators and messages occur: - "check engine light" - "traction control off" - "engine power is reduced" - "service traction control" - "service stabilitrak" additional symptoms: - loss of power steering - loss of power brakes once vehicle is turned off and sits for a few minutes. The vehicle will start and all of the symptoms above will go away with the exception sometimes of the check engine light. This indicator goes off after vehicle has sat overnight. Note this occurs very infrequently...sometimes months in between. August 2018, dealership (chev automation North, denver, co) diagnosed as transmission problem. Paid $5800 for replacement. October 22, 2018, all of the symptoms described above occurred again while on highway nearly crashing the vehicle. Wife now refuses to drive the car again. This vehicle is totally unsafe. It is unfortunate that a fatal accident must occur before any real attention is made to fixing a problem of this magnitude with GM vehicles.

The service department failed to properly repair my vehicle and possibly sold my vehicle to me with prior knowledge of faulty "battery charging system". I was told I just needed a new battery (which was replaced twice within the same week). This process began on 11/12/2016. I received the same error on my dash (battery charging system needs servicing) and my battery had to be jumped just like before on 4/12/2017. I contacted onstar and made an appt.with the service department at mccarthy morse Chevrolet for the next morning (4/13/2017). However I didn't make it because my car went up in flames in my garage about 15mins. After me and my children got out of it!!!! other issues that were addressed during this 6mo. Time frame included: A/C replacement, head gaskets and head bolts replacement, timing chain and cam shaft actuators replacement, and flywheel replacement. I feel like the services department had prior knowledge of these issues and didn't correct them before either.

The contact owns a 2013 GMC Acadia. While driving 70 mph, the vehicle decelerated to 40 mph and the traction control, stability control, and engine reduced power warning indicators illuminated after the failure occurred. The engine failed and the vehicle was towed to the dealer (jack maxton Chevrolet East dublin road columbus, Ohio, 43229, 614-681-0129) where it was diagnosed that the computer system failed due to the throttle body. The composition sensor was reprogrammed and the throttle body was replaced. The failure was not corrected and recurred after three months. The vehicle was taken back to the same dealer for diagnostic testing and a failure code was produced at the fuse box. The vehicle was not repaired. The manufacturer was notified of the failures. The approximate failure mileage was 70,000.

While driving the car it lost power, all the dash light went off, then the power steering shut down, while driving 45 miles an hr. Once able to pull over, the car shut down and could not start back up. The key would not come out of ignition. Had it towed to the local dealer the car was bought from. They reported it was the engine control module which they replaced but the car still will not turn on. Now the say it is an electrical short and can't find it.. this car is dangerous to drive as this is the second time this has happened and we feel that they are just giving us the run around. This car has been in the shop multiple times and never fixed properly

- Huntington, WV, USA

My vehicle has completely shut off 4 times in the past 2 years while driving, thank god there was no accident. Also my power door locks have locked and unlocked repeatedly by themselves without pressing any button in vehicle or key fob. The locks will go up and down until I shut the car off and then restart. The locks has happened 6 times. Also, my electric power steering gear(rack) needed to be replaced at 30000 miles. There were 2 recalls one for airbags and one for seatbelts. This vehicle is unsafe and frankly dangerous, thank god it never shut off on a highway. I have brought it to two different GMC dealer service centers and they can not diagnose or recreate the problem which means they cannot fix these problems. I don't know if this is isolated to just my vehicle or this is a problem related to this particular model and year car. I do not feel safe driving this car, please help us. Thank you.
