Engine And Engine Cooling Problems of GMC Acadia - part 2

The contact owns a 2017 GMC Acadia. The contact stated that while driving approximately 10-15 mph, the vehicle made an abnormally loud blower motor sound while accelerating, before the vehicle lost motive power. The transmission was shifted to neutral(n) and pushed to the side of the roadway. The tpms warning light was illuminated. The vehicle was towed to an independent mechanic who determined that the transmission clutch had failed, and the transmission needed to be rebuilt or replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed there was no recall coverage or warranty coverage on the VIN for the failure and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 132,000.

We have experienced multiple recurring issues with our 2024 GMC Acadia that raise significant safety concerns and affect the vehicle’s reliability and overall operation. First, the brake system exhibits persistent squeaking, even at low speeds or light applications. The dealership has inspected the brakes but the noise continues, raising concerns about premature wear or improper brake function. More concerning is the behavior of the automatic braking system while reversing. The system has repeatedly activated the brakes without any obstacle, vehicle, or person behind us. These unexpected braking events have created both physical and psychological stress for occupants and pose a real risk of causing a rear-end collision from another driver who may not anticipate sudden braking. Due to this hazardous condition, we have been forced to deactivate the automatic braking feature entirely, defeating a critical safety system the vehicle is equipped with. Additionally, the engine frequently runs rough during cold start and the initial warm-up period for the first couple of minutes. This rough operation is inconsistent with expected behavior for a new vehicle and has not been fully resolved despite service visits. The tpms sensors have also been problematic. Several sensors have already been replaced by the dealership, yet we continue to experience intermittent tpms faults involving at least two wheels. This results in repeated warnings, loss of real-time tire data, and uncertainty about actual tire pressure conditions while driving. We also experience rattling noises from the interior trim near the door seals whenever there is a cross breeze or windy driving conditions. This appears to be a structural or insulation-related issue. We have others, but this space only allows for 2000 characters, and after writing this sentence, there are only 113 characters remaining.

Ratle sound in the engine thinking it may be the timing chain. Code p0430 came on stating catalytic converter bank 2 needs replaced. We replaced O2 sensor downstream on bank 2 code was cleared by shop. After driving a few miles same check engine light came on and I took it to the shop they hooked it up to run the code and it was the same p0430 again.

Component: shifter assembly & jumper harness safety concern: can't turn off vehicle - carbon monoxide poisoning, physical safety when parking not at home, as I would have to leave vehicle running. . . Message in dash was present when I brought vehicle to dealer. Dealer also replicated no inspection other than dealer. Part returned to me. Warning message has been coming on for past 60 days or so, progressively getting more frequent I receive a 'shift to park' message in telltale after I have shifted to park. At times, vehicle will not shut off until shifter is manipulated for several minutes. I have concerns that I cannot park vehicle in garage, if I cannot shut it off. Gm is well aware of issue, but has yet to recall them. Dealer actually had replacement shifter in stock for a same day repair. . I was charged $778. 98 for the repair, and gm's customer assistance center response to me simply was to file a complaint with NHTSA. My wife does not feel safe driving, as there is no guarantee vehicle will turn off. Dealer replicated issue when I brought to dealership. Dealer has replaced part and has them. Warning lights only appeared when problem reared itself, initially began about 60 days ago, but is not occurring on approximately 2 of 3 shut downs.

I was driving along [xxx] . I stopped at walmart and shopped for about 2 hours. I was leaving walmart and was stopped at a red light at the exit from walmart [xxx] and traction control light comes on and a message came up and stated traction control off and to service stability control and the vehicle loses power right at the light. I checked everything I could and dis connect the battery for about 30 minutes and connected the battery back up vehicle still would not start. After sitting there for 3 hours the vehicle starts up. A week later the same thing happens again. I had to go through all the steps again so after a couple of hours. The vehicle started up. A few days later it happens shin but this time I'm at a stop sign on a busy road. I called road side service for a tow. No one showed up so I went through ll those same steps of disconnecting the battery and hooking it back up after a couple of hours and it stated up. I drove it home and started doing some research and found something saying to change the brake pedal position sensor so I done that and it worked for a few days and started doing the same thing all over again. S week later I drive it to the store and got almost home and the vehicle shut down again and would not start back up. I had it towed to my uncle shop nd he done a diagnostic on it and got about 4 or 5 codes. All of those things are very expensive to purchase. I just ran the VIN to check for recalls on the vehicle but couldn't find any but it should have been a lot of recalls because there are so many of these vehicles the exact same model and year with trouble with stability control nd brake and traction control issues. All the issues they hd on this car tht I have should not have been sold to anyone except the manufacturer. I wish I could just get my money back that I paid for it. $4700. 00 not included in the work I had done like the cv axles replace on both sides in the front. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I've had the engine stall before coming to a complete stop on several occasions. It also has been shifting hard and has had a delayed shift. The other day all of the lights to to screen and speedometer completely went out while driving then randomly came back on. That's the only speedometer I have is the digital screen.

Transmission issues.

While driving the thermostat will go to zero and the steering assist is disabled. I have read a lot of forums that this is a known issue. The only way to reset it, so we have a/c is to disconnect the battery and it will last a day or two and do the same thing.

I'm going to have to replace my thermostat and most likely my sensor. It will pop up saying (steering assist is reduced drive with care) my temperature gage on my dash will sometimes will not go up, my heat is acting funny. I've had also when I put it in park saying it's not actually shifted into park.

While I was driving a code came on my dashboard that read "steering assist is reduced drive with care". Soon after my check engine light came on. I pulled over not knowing what was happening. I took it to the garage to have it looked at and the mechanic stated that there are over 1000 GMC customers with this same issue and that the thermostat is stuck open. Which may cause major malfunction or even blow the engine. I looked up recalls for my vehicle and there are none but GMC issued a recall on other vehicles for this same issue. How do I get help here?.

The thermostat failed which cause the steering system to fail and car to not read temperature.

The vehicles engine siezed at 6,400 miles leaving us stranded on the side of the freeway for 3 hours and GMC is trying to pin the blame elsewhere. Car has been in the shop for 3 weeks and they are unsure if it will be covered by warranty. The only thing done to the car was an oil change performed at a GMC dealer.

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.

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.

The contact owns a 2018 GMC Acadia. The contact stated that while driving at 60 mph, the reduce engine power message was displayed. The rpm increased to high, and the engine revved. The accelerator pedal was depressed, but the vehicle failed to respond as needed. The contact stated that the failure was related to NHTSA campaign number: 18v358000 (fuel system, gasoline). The vehicle was taken to the local dealer, where it was determined that the high-pressure fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 98,000.

While car is in park, I get the "shift to park" warning after driving the vehicle.

Shift to park. Vehicle does not turn off when in park. This recall is in effect on other 2017 Acadias but for some reason ours is not under the recall. Had this issue in 2020 and it was repaired at our cost. It is now doing the same thing.

Sold 2018 GMC Acadia by lee GMC in auburn. Acadias shift to park was defective, dealership replaced before sale did not disclose, shift to park and transmission malfunctions occurred. I returned Acadia to the dealership several times and they would never properly fix or address my concerns now my vehicle is unsafe to drive. I have documentation to support the claims in my letter, I can send as well if you’d like. Thank you will send attachment.

My vehicle is 3 months old with 4650 miles. I was driving on the turnpike and without notice a warning on the dash advised that there was no oil pressure and to pull over. I had the vehicle towed to a dealer out of state since we were 3 hours from home. The dealer called today to advised the car needed a new engine. I asked what was the route cause and they advise the gm did not require the engine to be stripped to find one.

I have a 2018 GMC Acadia that is now displaying " shift to park " while the vehicle is in park. Upon extensive research I see GMC did issue a recall however, my particular VIN was not included. Its now displaying the error message which would lead me to believe it is part of the recall. I called my local GMC dealership (langhorne, PA. ) and they said this was not covered since my VIN was not issues a recall.

Steering assist reduced drive with care message. This is an extremely common issue and should be a recall. Alot of people including my dealer service advisor has this issue with their vehicle this message comes up fans kick on high a/c stops working and temp gauge stops working. It can be reset by unplugging battery or clearing the code.

Truck lost power randomly while driving on freeway spend so much money on fixing it this has to do something with the way the built it.

On about 01/20/2025 my transmission? auto started to shudder before going into 3rd gear threw 5th. Once in 6th gear at about 55 the auto starts to shudder and turns into a rumble feeling. My auto only has 100650 for miles on it. It has been serviced and have brought it to gm 01/24/25 to ask about it? after talking to service adviser. It would cost me 75. 00 for someone to go with me to confirm it is doing it. Then make an appointment for further evaluation. No price given at this time. But did not on paper! say that it is most likely torque converter causing the problem? confirmed it is not under warranty and there was nothing gm could do. I have been to at least 3 other shops in my area and they all say the same thing and price. Which is between 6 to 7 thousand dollars to replace the transmission. They all dosay that when it goes it could make me loose control due to lockup.

Oil is burning through. I have to get an oil change once a month or it goes completely empty. Spoke to multiple macanics now and all tell me that's a defect with the 2017 arcadia. I just bought this in August. I love it and don't want to get rid of it. Please fix this. I can't keep burning through oil like this. It's not safe for my kids and I.

Transmission control value issues. I was driving my car and rpm spiked up high and I coasted and there was no acceleration the rear wheel tires locked up and I felt a jerk. Placed the vehicle in park and pulled hand gear shifter into drive and the vehicle shifted back into park by itself. Same thing happened on placing the vehicle in reverse. Like the car had a mindset of its own. Luckily I was only going 20 miles per hour this could have been a fatality. This vehicle is not on the recall list. It should be because they use all the same parts.

While highway driving, engine suddenly lost power and car could not exceed 5 mph. Was able to get off at next exit and get to a local garage. Mechanic inspected. Bolt connecting high pressure fuel pump to cylinder sheared off leaving bolt body in cylinder, bending fuel pump and caused oil to spray over entire engine compartment. Repair unlikely. Engine will likely need to be replaced. Car has always been maintained. No indication of failure prior to incident.

I own a 2020 GMC Acadia that has experienced multiple major mechanical failures within one year. In January 2025, at around 74,000 miles, the transmission failed completely with no warning or clear indication of what was wrong. The vehicle suddenly lost power while driving, creating a safety risk for me and my child. I was quoted around $12,000 for the transmission replacement initially before getting gm involved. Gm covered all but approximately $3,600 out of pocket for me and also covered 100% of the timing cover replacement, which was found to be defective during the same repair. Now, at about 84,000 miles, the thermostat has failed, triggering the check engine light. This repair has not yet been completed and is estimated at around $1,500. My dealership informed me they keep thermostat parts in stock because this failure is so common on Acadias. There were no warning lamps or symptoms before any of these failures occurred. All repairs and diagnostics—including the current issue—were done at the same GMC dealership where I’ve always had my vehicle serviced on time. I’ve been a loyal customer and maintain my vehicle according to the recommended schedule. Despite that, I have faced repeated high-cost repairs on a 5-year-old vehicle with relatively low mileage, which has been financially and emotionally overwhelming—especially as a parent who recently lost employment. Having the transmission, timing cover, and now thermostat all fail in such a short time clearly raises concerns about the reliability, safety, and manufacturing quality of the 2020 GMC Acadia’s powertrain and engine systems. Given that gm has already covered most of the transmission and timing cover repairs and dealerships acknowledge frequent thermostat failures, this appears to be a systemic defect that warrants formal investigation.

Code 0128 coolant temperature sensor failure triggered reduced lane departure assist.

While driving vehicle stalled multiple times in the middle of the road, with service transmission and engine light coming on, causing unsafe conditions, causing accident and leaving passengers stranded. Battery being drained and needing to be replaced multiple times within 2 years. Vehicle stopping and shutting off on the highway causing dangerous driving conditions!! radio and lights flickering, with radio freezing and shutting off. Electrical system not working properly and overheating!.

On 11/26/24 my wife was running errands in her vehicle when the power shut off and killed the car. She was in the left lane of a busy state highway. She was able to coast off the road slightly before the vehicle came to a complete stop. The dashboard said to press brake and start button, but the car would not start. The vehicle was also stuck in drive and would not switch to park, neutral, or any other gears. Police came and had to push her vehicle with theirs into a nearby park lot so a tow truck could pick it up. It is currently at a gm dealership waiting to be looked at.

Steering assist reduced. No parts available and vehicle is not safe to operate.
