2018 Buick Enclave owner complaints

There are two issues: while backing up the car, especially down a hill, the brakes do not work/engage temporarily. Eventually the brakes engage, but you travel further than you intend. The "service brake system" light appears also. This is an intermittent problem. The second braking issue is that the emergency brake will engage without the button being pressed. It just happens and it the emergency brake is difficult to turn off, the car may nee to be turned off on back on to fix. The "service emergency brakes" light appears. This has happened while backing up and in forward in normal driving conditions.

While driving on very slick roads on a highway, I attempted to brake the vehicle in preparation to making a left hand turn. I could not stop the vehicle. The wheels kept pushing me forward. I could feel the ABS pulsing but the vehicle would not stop. Luckily, no one was ahead of me or I would have hit the vehicle. It felt like the car was overriding my attempts to stop it. I wasn't just sliding on slick roads; the vehicle was actively pushing me forward.

The brake system ABS module/sensor malfunctions- yes it is available for further inspection. Safety is an issue due to the ABS indicator light on. Yes, the problem/issue has been confirmed by a dealership. No inspections have occurred other than the dealership. The only warning is the light indicator for the brakes, parking ABS.

Random activation of parking brake while the car is in drive. Most often occurs when on a slope and a low speed. Multiple incidents have occurred since purchase it has continued to get worse. The vehicle has been in for service many times with no resolution. I opened a case with gm on 9/12/2019 but they have not returned my calls or emails since 10/3/19. There has been several instances of this issue and was documented in a forum post that parallels our issue https://www.enclaveforum.net/threads/2018-avenir-electronic-emergency-brake-fault.22631/ 1) parking brake coming on at highway speeds as wife transported my daughter and some of her friends to the mall. At a red light, close to the mall my daughter commented on a smell. They pulled in the parking spot at the mall, my wife n

The e-break warning came on twice after releasing the e-break when parked, the warning came on shortly after pulling from a shopping center parking lot. The e-break light was flashing with the 'service light' active and a display notification of emergency break issues. Both of these two incidents happen after the last service update n19221631 was implemented back on 5/2020. The first one was present around september 2020 and the last one on 11/23/2020. I'm not sure if these two incidents happen due to the implementation of the service update but it seems coincidental that they happen shortly after the service update as this condition did not occurred before the service update. I do not drive my Buick much with only about 11k miles currently so it is not obvious the problem is due t

Several times I have been stopped at a red light, and my parking break will come on without me engaging it. I was almost hit by other vehicles the last time my vehicle did this. People were blasting their horns and speeding around me because I was unable to move my vehicle. Because I had not manually engaged my parking break, my vehicle would not allow me to disengage the parking break until after it finally read that I engaged it. It took me 10 minutes of having to turn my car off and back on and trying to engage the parking break manually before the vehicle finally noticed it was engaged and would allow me to disengage my vehicle so that I could move it out of the way. This has now happened 3 separate times in the last month. It is an extremely dangerous situation and is making me become

The contact owns a 2018 Buick Enclave. The contact stated while stopped at a gas station; after refueling the vehicle, the vehicle was restarted but was unable to shift to drive(D). The contact attempted to shift to reverse(R) and the shift lever failed to respond. The contact stated an unknown warning light was illuminated. The vehicle was towed to a local dealer where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 71,000.

I purchased a new 2018 enclave in september of 2018. I received a recall letter for the vehicle sometime during the spring 2019 so I went to my dealer service department to get it check and I was told everything was fine. Then in september I noticed the check engine light came on and the vehicle would not accelerate properly so I took it to the dealer service dept. Asap. They told me there was an issue with the transmission. They said that because I had less than 5,000 miles this issue should not be occurring. It's been 4 months and I have not received a reasonable time frame for when my vehicle will be ready. My rights as a consumer have been violated because I received a defective vehicle, which put my family and I at risk. The same dealership offered to give me a loaner vehicle that end

-A few weeks prior to accident, while driving down a 65mph highway in TX, vehicle side mirrors were folding inward. Continued to fold inward after hit button to open them multiple times. Even did this after pulled off highway and stopped/started vehicle and exiting vehicle and locking to try to create a "reset" of system. (Auto folding windows feature in infotainment was NOT selected to be ON before or after this incident! Auto-folding sidemirrors are tied to the electron shifter status and should only engage when turned ON in infotainment option AND vehicle in PARK. This was occurring over 2-3 days while driving on highway at 65mph) Accident: -Pulled into parking spot and placed vehicle in PARK. -Front Dash Camera audio indicates the "Ding" confirmation of park and hear vehicle doors u

Second time in less than a month on a 2018 Buick enclave that air conditioning unit/evaporator in vehicle is not working and vehicle is blowing hot air only. This occurs whether vehicle is in motion or stationary. This happens when vehicle is first powered on or over an extended drive (45 mins). Does not oscillate with change in speed. Does not oscillate with length of drive. Hot air blows the entire time and noise comes from dash that sounds like hydraulic door hinge.

My vehicle has begun all us sudden flickering headlights from low beams to high beam when driving and also it ay the airbag safety light turn on with the locks also doing a closing and opening while driving.

The car has an auto-stop feature however at times, when the car is stopped, the entire electrical and engine shuts down even while the car is in drive. The driver must restart the car and put the car into park and then back into drive. When the car restarts, several lights/messages turn on including "Service Transmission" and the "Service Parking Brake" message and parking break light. This is a safety and hazard issue as it has happened while in traffic on the freeway when at a standstill.

The Electronic Parking Brake has had multiple apparent malfunctions and one complete failure. On several occasions the parking brake failed to disengage completely with multiple warning dash lights illuminating. One such incident apparently self-corrected after being left parked overnight our semi-heated garage, with another incident only partially disengaged the parking brake with warning lights indicating a parking brake malfunction, and after driving two to three miles returning home the right rear brake was baking hot. The latest malfunction was a complete failure of the parking brake to engage at all, with the warning lights again illuminating and would be an obvious danger while parking. The vehicle is just over four years old and was two-and-a-half months out of warranty at the

The contact owns a 2018 Buick Enclave. The contact stated that after picking up the vehicle from the dealer for a different failure, the exhaust pipe made an abnormally loud sound while driving. The check engine and other unknown warning lights were illuminated. The vehicle was taken back to the dealer, who determined that the catalytic converter had failed and informed the contact that the catalytic converter and the front exhaust pipe needed to be replaced. The vehicle was not repaired. The contact related the failure to Special Coverage Adjustment: N212356540 (Front Exhaust Pipe); however, the VIN was not covered. The manufacturer was made aware of the failure and advised the contact to report the failure to the NHTSA Hotline. The failure mileage was approximately 100,000.

The "start stop" feature caused a life threatening hesitation upon acceleration from a full stop at an intersection. Enclave does not offer any override for this option. There must be a firmware update provided by gm to allow it to be disabled!!! This is going to kill somebody!!!

2018 Buick enclave. Consumer writes in regard to engine shuting down when vehicle stops. *as the consumer stated the start stop feature intermittently shuts down the engine when the vehicle is idle and does not recover quick enough for safe starts in traffic. *js

Buick not a year old, in our garage very strong odor of gasoline cannot let it inside the garage it smells strong going into house attached to garage!

At least 3 or 4 times, the car has remotely started itself while the key fob is in my pocket. Two times, the car was in my closed attached garage. To remote start the car, I would have to press and release the lock button on the fob, then hold down another button for four seconds. At times while I am working around the house or garage, I hear the car beep, indicating that my movements pressed the lock button. On the times mentioned above, evidently my movements pressed the two buttons, causing the car to start. I mentioned this to the service department of our Buick dealer, Dave Cross Motors in Lee's Summit, MO. They were not too concerned, and said that the engine would shut off after 10 minutes. I feel this could be a health concern. If the car did not turn off after 10 minutes, carbon m

I am told by graff Chevrolet, okemos, mi, that at only 63,000 miles, my rear toe link adjustments are separating and needs to be replaced at a cost of $407 plus a $90 wheel alignment plus tax. In my research, I see that the gm cadillax srx has had the same issue. I am concerned for my safety first off, but also believe gm should recall and warranty these parts.

The headlights continously and irregularly flicker between high and low beam while driving at night. I have no control over it and cannot turn off the high beams when they activate. This is highly annoying to drivers ahead me, as they believe I am trying to get their attention (or be obnoxious). In these times and the legalization of open carry weapons in the state of Florida, this can be highly dangerous if the wrong person is aggravated by unintentional signaling. I have already had issues on the road with drivers not happy with the high beam flicking on and off at them while driving on the road. They have become very aggressive, following, slowing down, honking at me because they think I am being impatient or trying to tell them someting is wrong. I spent $2000 in January 2025 trying t
