2021 GMC ACADIA

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

General Motors, LLC (GM) is recalling certain 2020-2021 Cadillac XT5, XT6, and GMC Acadia vehicles equipped with the optional Surround Vision feature. The rearview camera coaxial cable connectors may have been crimped improperly, causing the rearview camera to fail or function intermittently.

Risk: An inoperative rearview camera can reduce the driver's rear visibility, increasing the risk of a crash.

FUEL/PROPULSION SYSTEM

My Acadia, 2021 has just 36011 miles. Car sputtered a few times like it was running out of gas and stalled as I was driving home in rush hour traffic. I couldn't even get it off the road. No warning lights or advance warning. Waited 3 hours for AAA (told 20 minutes) and then towed to dealer. Tow person could not get it into neutral so they used the sleds to ramp it up onto the flatbed. The dealer replaced the fuel module board which seems to be a common problem with these cars. Dangerous in that I thought someone might rear end the car while sitting in the single lane. Look on the Acadia forum and you'll see this is common and no recall has been issued and it sounds like it could very well happen again.

FUEL/PROPULSION SYSTEM

I was driving down a heavy traffic expressway with a lot of semi traffic and the SUV started puttering. All of a sudden it died, the check engine light came on and I started to slow down quickly. I was in the middle lane of 3 lanes going 70 mph. VERY LUCKILY, I was able to pull to the right and barely made it onto the shoulder. The SUV had $28,972 miles on it. It was more that 100 degrees outside at the time. I called for a tow and had to wait over 2 hours. My car was nearly hit many times during the wait. The whole situation was very dangerous. What if my children were in the car at the time???? The tow truck driver was nearly killed while trying to get it on the truck. He had to call the police to block the lane. He stated that he could not put it in neutral and had to do something else with it to get it up. It was towed to the dealership where I purchased it. They did the diagnostics and said it was a fuel pump module issue. Less than 30,000 miles and this happened. I was planning to take a trip through the mountains, but at this point I do not feel safe at all in this vehicle. THIS SHOULD BE A RECALL IF GMC IS AWARE OF THIS ISSUE!!!!!

FUEL/PROPULSION SYSTEM

Car was parked overnight in my garage and in the morning it would turn over, but not start. Had to have it towed to my GMC dealer, but had great difficulty moving the car out of the garage because the transmission remains in PARK if the engine is not running. Had this happened on a highway while driving and without a place to safely get off the road ( which HAS happened to others who have made this same complaint to NHTSA), this could have been an extremely hazardous situation for the occupants of the vehicle. The engine will suddenly shut down, power steering is lost, and power braking will also be lost. This problem was diagnosed as a failed fuel pump module. The failed part was replaced by the dealer (GM part#13554820). The service manager acknowledged that this is a known and common issue and that GM is aware of it but has not issued a voluntary recall. The manager also advised that this part has not been updated and that it may fail again without warning. Please....this is a serious safety issue that needs to be addressed before someone is injured or killed while abandoning a car stalled in traffic that cannot be moved.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Instrument cluster malfunction. Entire instrument cluster blacking out every 60 seconds, then rebooting nonstop while driving. While this was occurring, none of the advanced driver assistance systems functioned, nor did the speedometer or other gauges. This occurred while on a trip, and meant having to travel a long distance without having emergency braking, collision warnings or the ability to monitor speed. The car was taken to local dealer and they replaced the entire instrument cluster.

The fuel pump control module failed, 2021Acadia Denali First time, 9/22/21 8073 miles, the car was parked at the residence under the car port, when needed, the car would not start. No check engine or other indicators. Car was towed to dealer for repairs under warranty. Second time, 10/6/23 31879 miles, we were driving the car on a rural road, 55 mph speed limit with no shoulders when the car stopped in a curve. Had to flag down cars to keep them from hitting us for an hour till the wrecker loader it on the truck to take back to same dealership for warranty repairs. Third time, 7/29/25 48199 miles, we were again on a rural road 55 mph speed limit when the car stopped with my 71 year old wife alone in the car, again in a curve. This time there was a check engine light. I drove my truck to pick her up and assist her until the wrecker came. This time with luck I was able to restart the car and I followed her to our home where the tow truck picked it up and brought it to the same dealership for the third time for repairs under warranty. All three times the culprit was the fuel pump control module. Each time it was the same code in the ECM. Each time the dealership said they did a full check on the fuel system, pump, etc. and only replaced the fuel pump control module.

POWER TRAIN

Driving out of state. My 2021 Acadia with 41,172 miles. When pushing the gas to go there is slippage when trying to accelerate. MY car went automatically into neutral saying transmission and then not start. After a rest period it would start then repeat the same issue. In bumper to bumper traffic on I75. The most Terrifying & UNSAFE place to be at 75 to 80 mph. We happened to be driving up on construction and slow down traffic. When the car stalled. Towed it to a transmission place because of code. They replaced the DTR1 PCM.

FUEL/PROPULSION SYSTEM

Driving on rt 95n in Ga. Going 70 mph and vehicle just bucked and shut off. At the time I was in the middle lane and almost got hit by a tractor trailer while I was trying to get to the right side of the road. Called general motors roadside assistance and they supplied a tow company to tow me to a dealer in Ga. About 35 miles away unfortunately it was Sunday dealer was closed and I had to get a taxi to take me to a hotel with all my luggage. On Monday morning when the service dept. Opened they advised me the fuel pump module had failed and would be replaced. Luckily most times when vehicles shut off with push button electronically shifted transmissions you can't put the vehicle in neutral to move or tow but after many tries it went to neutral(according to the tow driver) also after researching my vehicles failure I found this is a wide spread problem among many gm suvs and trucks! Hopefully a recall is in the future before someone gets killed!!

SERVICE BRAKES

I was driving down the road and all the sudden my breaks locked up. Like I had to stand on the break with both feet for it to barely stop. After getting it to the repair shop they said my vacuum pump exploded. My problem is it’s very well taken care of car and absolutely no warning light was on. I had no warning at all just all the sudden wouldn’t stop. Now I’m 7,600 in the hole because of this and very upset my not even 5 year old car is having these problems.

ENGINE

While driving the engine cut out. I wasn't able to get the vehicle off the road and had to put in an acceleration lane until I could get a tow. Other drivers entering the roadway were accelerating and some didn't realize that my road hazard lights were on and almost hit me. The vehicle was given a diagnostic check by a service station and say that the Fuel Pump Power Control Module is not working. After checking the Internet I found a recall for this item on other GMC models but not the Acadia. There was no advance warning for the malfunction.

ENGINE

I have had nothing but issues with this vehicle from the day I purchased it. I should have been more leery of purchasing a vehicle with so few miles on it as a certified vehicle. First issue lift gate wouldn’t work. Had to have sensors replaced twice. Next was the purge valve sensor that has went bad 3 separate times. Then the crankcase vent sensor. Paid a fee for diagnostics, it was not repaired took it back when the engine light came back on, they replaced it without charging but I was advised it’s not covered under warranty. And most recently my check engine light came on yet again today now reading an issue with the engine cooling system. Unfortunately the dealer is so booked out, my only option is to drop it off and hope they can get it in by a cancellation or no show. Seems there are new issues ever 3-6 months with the car.

FUEL/PROPULSION SYSTEM

May 2023 we took the car to the GM dealership for a electronic recall. We reported a rattling noise at that point in time. Whatever repair was done that the car ran w/o any noise for nearly a year. April 2024 the catalytic converter failed at just 61K miles on this vehicle. The mechanic at the same dealership noted a broken mounting bracket and replaced the catalytic converter. October 24 2024 at 76K miles the car started making the same noise. The mechanic at the same dealership noted a loose mounting bracket due to an excessively vibrating catalytic converter, a crack on the cat converter, a leak and sequentially damaged front pipe. They noted they made all of those repairs. They noted they test drove the vehicle and verified the car was repaired. October 26, 2024 after those final repairs the car made a loud revving noise and emitted a smell of sulfur. The next day the car died on the road while driving. Every system of he vehicle shut down and I narrowly avoided getting hit from behind. On 11/2/24 We had the car towed to the dealership again. The mechanic noted the recent replacement on the cat converter & oil had leaked intermixing. That caused the motor to seize and the car to stop working while I was on the road driving. I can't imagine what could've happened to me had it stop on the highway at 65mph.
