Electrical System Problems of Buick Enclave - part 1

I am a [xxx] and owner of a 2018 Buick Enclave that suffered a catastrophic transmission failure which nearly killed me and my child. On Friday, [xxx], while driving westbound on [xxx] from edison, NJ to my home in easton, PA, my vehicle suddenly and without warning came to a complete halt in the fast lane. A driver tailgating me swerved at the last second to avoid impact. Moments later, when I tried to move again, the car lost all power and drifted helplessly across two lanes of speeding traffic, directly into the path of two tractor-trailers barreling down at highway speeds. This was the hottest day of the summer, and I was left in terror, fully aware that one wrong move would have ended our lives instantly. The fact that my child could have lost their only parent because of a mechanical defect is beyond unacceptable. The stress, fear, and trauma of this incident cannot be overstated—it was a near-fatal event that never should have happened. My mechanic has since confirmed the transmission is destroyed, with black metal fragments throughout—clear evidence of internal failure. Only two months earlier, in June 2024, the car passed inspection with no codes or signs of a problem. This was not wear and tear; it was a hidden, catastrophic defect. In December 2024, gm recalled more than 461,000 vehicles, including certain 2018 Enclave models, for transmission defects leading to rollaway and internal failure. Source: the lemon firm, 12/18/24 [xxx] ). My case mirrors the defect exactly, yet I never received recall notice. I demand gm confirm my VIN’s inclusion and cover the full cost of repair or replacement. I barely escaped a fatal crash. Gm must act immediately before lives are lost. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Problem: the back hatch or trunk door pops open randomly on its own, many times a day. In a parking lot once. It hasn't happened while I've been driving. Safety issue because if it were to open while in public and a person wasn't in the vehicle, then anyone could enter the vehicle and theft could occur. Yes, the vehicle is available for inspection. A service center confirmed that it's the switch in the back hatch. No, the vehicle hasn't been inspected by manufacturer, police, or insurance. No, there haven't been any warning lights with this issue.

Power liftgate was functioning erratically and now it won't open at all. Currently there is no way to manually open the liftgate or access the rear of the vehicle without climbing through the vehicle to get to the trunk area. Electrical switches on inside, exterior of vehicle nor the keyfob will open the liftgate. Previously the liftgate opened on its own at unintended times and now it has simply quit working. Safety issue was when it was opening while driving. It is not currently doing this since it won't work anymore. Complete failure happened around 54k miles.

During a rainstorm water is entering the fuse box under the glove box and the carpet and padding underneath is soaking wet on the right front floor. When the fuse case was opened water started to drip out. The engine continues to run with the key off and the only way to stop it is to pull the ignition fuse under the hood. Unfortunately the battery died by morning and I could not get it charged for a few days. Now I have learned how to take the battery cover off which is located in the back of the car and remove the plastic covers under the mat so I can disconnect the battery so it doesn't run down. The rear wiper will not shut off now since this started. I am a 75 yr old widow and wonder how this problem has not been on a recall. It causes a very dangerous situation. I will try to see if I can get it into a Buick dealer this week and pray god it doesn't cost me an arm and leg to repair it. There are service bulletins on this problem and seems to be quite freqent yet I have not received any notifications from you. If this happens at night in a parking lot what am I to do? can the car catch on fire by not shutting off?.

Check engine light came on first and then the infotainment went blank for three days. Took to dealership for the software update which shut the infotainment system down completely.

My car has shut off multiple times , electrical shorts, intermittent no start, intermittent misfires all the time but randomly , injector codes even when replaced and injectors are good , yes come check out my vehicle no shops can find out what's the problem practically the whole front end has been replaced and problems still happening it is congruent with a recall but shows nothing from VIN.

Start/stop function malfunctioned in the middle of the road, this has happened multiple times before and after replacing starter and battery, looked at by several mechanics. If I stop the car at a light or in traffic my car will dint turn back on or let me shift. Thus a safety issue because I could have been hit as it stopped in a busy road and people had to move around my vehicle. Engine light came on after failure and ceased the engine and I couldn’t move to the intersection. I also just got an oil change. They first appeared a few months ago and I had already gotten work done on it and it keeps happening.

The contact owns a 2023 Buick Enclave. The contact stated while the vehicle was parked or while driving, the infotainment system failed to display as needed. The contact stated that the failure persisted, and a dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the technician was unable to determine the cause of the failure. The contact stated that a software update was performed and an undisclosed part in the infotainment system was replaced. The manufacturer was notified of the failure several times but offered no assistance. The approximate failure mileage was 13,500.

The contact owns a 2025 Buick Enclave. The contact stated that while operating the vehicle the display screen had intermittently malfunctioned and only a black image was displayed. During the failure several safety features were unavailable to the driver such as the speedometer, fuel gauge, tire pressure information and the backup camera. The vehicle was taken to the local dealer who reprogrammed the display unit but the failure continued to intermittently occur. The manufacturer was notified of the failure. The failure mileage was 800.

The car shuts off at random when coming out of autostop, the car will disable power steering when coming out of autostop to make turns making it difficult to turn the steering wheel. Coming out of autostop is typically when you are trying to go or make a turn. This has been an ongoing issue that happens often. The issues began around 60k miles.

Vehicle would not go into park fortunately we were in a safe location to avoid a possible accident or injury. The vehicle has electronic transmission shifting. According to the dealership the park solenoid in the transmission valve body failed. This prevented us from putting the vehicle in park so it could safely be shut off. We were able to set electronic parking brake but ignition continued to remain on. Eventually had to disconnect the negative battery terminal. Had vehicle towed to dealership but could not release electric park bake or start vehicle with battery terminal reconnected. This is becoming a common problem with this transmission, so common that parts are on back order. This could be a very unsafe problem with this vehicle in the right circumstance. There should be a recall on this transmit that is used on multiple gm vehicles.

I had taken to alpena mi. Buick GMC address 133 johnson st alpena mi. 49707. When the warning come up on the message center on the dash 28/3/24 that said service side detection system and in the side mirrors each side light up all the time and would cost $875. 00 installed at that time had to pay $80. 19 inspect and advise. At that time was unable to afford that cost to have fixed. So with those light on in your mirrors it was a unsafe to drive in daylight hours and worse in night time driving so we had to limit our driving because of this and both my wife and myself are on disability. . It was a distraction and made for unsafe travel for ourselves and for other drivers on the roads. We were able to afford on 02/04/24 and at time was taken back to. The same dealership for repair at that time they installed the side detection kit cost was $812. 66 which was less then the original cost. Question number 2 with this lights on in your mirrors at all times when we would be driving day and night it was a big distraction that you never would know if someone was in the next lane to you on two lane road or on the interstate. So each person was at risk in our vehicle as well as other vehicles. Question number 3 yes that was confirmed by alpena Buick GMC the dealer I had taken the car to back on 28/3/24 . Question number 4 as far as it being a gm dealer and being a gm part I would say yes. Question 5 yes as I told you in q neeuestion 1 it had on the message center in dash service side detection as well as lights on in both mirrors. In my words this is a reason this should be a recall first for people that are driving and can't afford to have fixed this is a accidents waiting to happen with death please do a recall.

The entire audio system went out, including the radio, blinkers, lane detection, crash detection, back up indicators, onstar, anything related to any kind of sound whatsoever to the vehicle does not work. The issue that we have discovered is the wiring harnesses in the doors are filling with water and shorting the entire system.

The rear switch on our tailgate has failed and it allows the tailgate to open/close randomly on its own while the vehicle is locked even. I contacted Buick about the problem and they said didn’t care, but this can happen while the vehicle is moving down the road as well as when parked. It’s not necessarily a typical safety issue that are normally recalled for, but it does pose significant safety issues if you want your car to be locked and you come back from the store and it’s not and people are free to break it or if it were to happen while moving. We had this happen on our car at around 38,000 miles. From reading other Buick forums to try and figure out what the cause is, it sounds like it’s a somewhat common occurrence. It’s alarming that it can open while the vehicle is locked.

The cooling fan motor assembly is shorting out internally & blowing the 70 amp fuse dedicated to that circuit. Mustreplace fan assembly and fuse to correct this concern.

If any warning light comes on such as my add air to a tire (it always tells me the wrong tire), all of the warning lights start flashing. Things shut off (radio, dash lights, backup camera) and sometimes the car will shut completely down and come back on. I am afraid to drive very far.

When the driver seat is moved the service air bag light comes on. When you move the seat again the light goes off.

While driving down the road, the locks on the doors will suddenly lock, unlock, lock and unlock. After that the engine slows way down losing power, then it will be okay to give it more gas and it speeds up. The last couple of times this happened, the car lost all power and stahled.

My vehicle stalls for no reason. The engine power is redused, stabilitrack, and traction control lights come on. The vehicle stalls in the middle of traffic. The brake and steertng wheel don't work when the engine stalls. The seatbelt and airbag light comes on. I went to get that repaired and the dealer told me that the repair time period had expired.

Engine reduced, traction control, and stabilitytrak lights came on 11/3/2023. Car died on me while I was sitting in traffic. Took car to firestone on 11/9. They stated car needed oil change and tune up. On 11/17/2023 while in the line at a drive through lights came on again and car died in drive thru. Car was towed back to firestone. Firestone said it was pulling codes they didn't know and the car needed to go a Buick dealer. Towed car to bob brown Buick on 11/24/2023 bob brown said car just needed a battery. After one hour the car lights popped on again and car died in the middle of the street. Towed car back to bob brown another diagnosis was completed and was told I needed a catalyst converter. Towed car to midas and paid another diagnosis. Midas fixed 3 gaskets and sensors. Car died again driving down the street going 35mph almost causing an accident. This electrical problem is very dangerous and unsafe.

When starting our 2020 Buick Enclave I noticed the low voltage battery light stayed illuminated after startup. A message followed on the message center located in the center of the gauge cluster. The message read service electrical charging system. Followed by a message stating low voltage vehicle MA stall. This particular vehicle only has 38,000 miles on it and I have not experienced any issues with the electrical charging system prior to this incident. There have been no indication as to the battery or alternator failing (ex. Dim lights, flickering lights, malfunctioning electronics/electrical equipment, unusual noises coming from engine bay). I acknowledged the messages with the button on the steering wheel. I proceeded to drive and the low voltage light went off shortly after. I proceeded to drive approximately 75 miles without incident. Shortly before arriving at my destination the low voltage warning light illuminated and the messages appeared on the center screen on the instrument screen. I again acknowledged the messages ,but this time the low voltage light stayed illuminated until I shut the vehicle off at my destination. I visually inspected the battery post, connections, serpentine belt, and alternator. Nothing looked out of the ordinary and all connections were tight and free from corrosion. Nothing smelled burnt as it would if wiring overheated or alternator. I proceeded to start the vehicle. The vehicle started without hesitation and the low voltage light was not illuminated. I proceeded to drive to a local parts store which was a couple of miles away. On the way to the parts store the low voltage light came on and the messages appeared. I left the vehicle running at the parts store. The employee tested both alternator and battery. The alternator was showing that it was failing only producing 8. 6 volts to the battery while the vehicle was running. I proceeded to leave the store. At this point all electrical shutdown simultaneously. Vehicle to be towed.

The infotainment system locks up. Its like all features are on mute. I can't use phone, radio, contact onstarr or use navigation system I have a heart condition, when this freezes I have no way to reach help. The dealership has tried multiple fixes, they say they are just seller, gm is the manufacturer. Gm no longer takes my calls. They have blocked all my numbers. There is no warning, it just stops working gm suggests I turn off vehicle, get out wait 20 minutes and the system should reset, I have tried to disconnect my phone from bluetooth and they seek each other out and reconnect. I live very rural, 20+ miles to anywhere. I have no way to get help.
