2017 GMC Acadia Fuel system Problems

Vehicle has experienced multiple electrical and mechanical failures at unusually low mileage. Purchased at 32,000 miles. At approximately 50,000 miles, the factory radio/infotainment system failed completely. Electrical systems were observed remaining active after the vehicle was powered off, suggesting an underlying electrical fault. At approximately 60,000 miles, the power steering rack and fuel pump both required full replacement and were confirmed and replaced by an authorized dealership. No warning lights appeared prior to these failures — components failed without any prior indication. At approximately 100,000 miles, the transmission began failing and exhibits the known torque converter shudder issue widely reported on this vehicle platform. The shudder was present prior to full transmission failure symptoms appearing. The pattern of premature failures across multiple unrelated systems — electrical, steering, fuel delivery, and transmission — suggests a broader manufacturing defect.

The contact owns a 2017 GMC Acadia. The contact stated that while parked at her work, she had attempted to start the vehicle and was unable. The contact had the vehicle towed to an independent mechanic who diagnosed the vehicle and determined that the fuel pump needed to be replaced. The vehicle was repaired, but the failure reoccurred. The contact had smelled the strong odor of gasoline from the front end of the vehicle. The contact stated a co-worker had looked underneath the vehicle and confirmed the leak of gasoline. The contact had taken the vehicle back to the same independent mechanic, who advised that the fuel pump had failed and needed to be replaced. The vehicle was repaired. Additionally, the contact stated that she was in a parking lot at a shopping center as she was looking for a parking spot, the driver's side air bag exploded, there was no crash.

Shift to Park light remains on after you’ve put the car in “park” which could potentially run the battery down. Car does not recognize when it is in “park”. Have to “jiggle” the gear a bit, in hopes that it turns off.

I’m just reporting several known issues. First, with code P2138, which I got today at Oreilly after my car started throwing warnings. I used my parking brake briefly and afterwards got the following warnings on my car: “Steering Assist is Reduced, Drive with care”, “Engine power reduced” , “Propulsion Power is reduced” , “Service Parking Brake”. I’ve never even had one of these warnings. I’ve only gotten “shift to park” which is another known & common issue. With this P2138 code, it can affect acceleration and essentially loss of control over it, but seems I suddenly have several issues. Recently the infotainment system is possessed, touch screen stops working, it calls people by itself, beeps and scrolls by itself and is essentially useless. Might as well be driving at 1997 something or other, at least I could play a tape or CD. This is Denali trim at 87K miles. Primarily though I’m concerned with this code, if it’s legit, it is very dangerous. How unreliable and unsafe to not know.

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.

GM issued Special coverage N192210240 for repair/replacement of the evaporative emissions purge valve because it may not fully close. The special coverage states that the dealer is to replace the part at no cost to the customer as necessary until 150,000 miles or 11/12/2026 whichever occurs first. Since owning the vehicle in question I have had this particular part replaced three (3) times, approximately every 20,000 miles. Each time this particular part fails my check engine light is illuminated, my vehicle stalls immediately after refueling, my garage and home quickly fill with emission fumes upon starting the vehicle, and the vehicle idles rough when stopping. The GM dealership replaced the part the first 2 times it failed at no cost to me stating that it was covered under GM Special Coverage, but the third and most recent time refused to honor the special coverage. They, instead, stated that I had to pay $189.99 for a diagnostic in addition to the cost of the repair despite the fact that my vehicle was still within the special coverage parameters and the special coverage bulletin states "as necessary" . The dealership stated that the special coverage was only a one-time use, and I was to pay for repairs each additional occurrence. There is clearly an issue with this part, and GM has acknowledged that by offering the special coverage. This coverage should be valid for the entire time stated because this is clearly a faulty part.

I was traveling at the posted speed limit of 80 mph on [XXX] in South Dakota at [XXX] and the GMC Acadia was working without any issue when all of a sudden various warnings flashed on the dashboard with one of them being power saver mode engaged. Within about 3 minutes various other warnings flashed and the vehicle motor turned off along with all of the electrical systems. Luckily, I was able to maneuver the GMC Acadia to the shoulder of the highway safely. The vehicle would not start and for about a minute or so we were trapped in the Acadia. We could not unlock the doors or wind down the windows until I pressed the start/stop bottom several times. Onstar did not work either. Once we could get out of the Acadia, my wife called 911 and in roughly 20 minutes or so, a police officer arrived at our location. We also called AAA and had a tow truck take the broken down GMC Acadia to a garage for repairs. It turns out that the alternator went bad and rendered our GMC Acadia useless in roughly 3 minutes from the initial warning. There was absolutely none of the tell tale warnings of a bad alternator. We did not see or observe any dim lights, hesitating starts or any other things associated with a bad alternator prior to the 3 minute warning before the vehicle completely was inoperable. We are very lucky to be alive. If [XXX] was more congested with traffic at the time of this incident, we might have been serious injured if not killed. IMO this GMC Acadia is a death trap. This vehicle warns the driver when the key fob’s battery is low many weeks before it needs to be replaced. It should warn you more than 3 minutes if not several hours prior to the vehicle being completely immobilized. It should be noted that the check engine light came on several hours before this incident and I called Onstar and they ran the diagnostics and returned a P0420 code which is related to emissions. The check engine light turned itself off about 1 hour before incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMAT

At roughly 50,000 there is a transmission line leak in the vehicle. GM has already recalled 2018-2020 model-year GMC Acadia SUVs and other models for this problem due to risk of fire. Whether it is the same cause or not, such a problem leads to the same risk.

WE PURCHASED A 2017 ACADIA AWD SLT ON DECEMBER 28, 2017. THERE WAS A RECALL ON GM BULLETIN #19-NA-206 FOR (SHIFT TO PARK) ISSUE.
