   After purchasing this 2023 Buick Enclave July 26, 2026 two days later I heard a vibrating rattle coming from under the hood. I raised the hood and pinpointed the noise to be coming from under the motor cover. I could not remove that cover myself. I reported it to the dealership where I bought it and they said when I bring it in to have the Paint And interior, Protection to be applied that they would take a look for that rattle sound. After their inspection on 9/16/26 they called me back and said that it was the EVAP purge solenoid tube. And that the fix would be to put two rubber dampeners onto the purge tube line to isolate the vibrations and stop it from hitting other engine components. Then secure the dampeners with tie straps. They wanted to charge me $331 to do that. I said I’m not paying that so I proceeded to look up this information online and I found there’s an actual Technical service bulletin. It’s not an official safety recall but GM is aware of it and the bulletin number is 21 – NA – 023. So I spoke with my bumper-to-bumper warranty people and they said that if the actual purge valve piece was not broken, then it would be most likely at my expense. The noise is caused by fuel vapor pulsations vibrating through the EVAP purge solenoid tube. The Symptom: drivers typically notice a rapid clicking or rattling sound under the hood, which can sometimes be mistaken for engine knock or failing engine mounts. Note on code: This specific bulletin is strictly a noise concern and does NOT trigger a check engine light or throw trouble codes like P0496 on its own. The notice from GM also states that if a vehicle is still covered under its factory, bumper-to-bumper or emissions warranty, the repair should be completed free of charge. If you are out of warranty, you may be subject to diagnostic fees or out-of-pocket cost for the fix. After speaking with the service department at that dealership, they said that they were not going to replace the purge valve.

   Right-side LED headlight assembly failed at under 3 years and ~55,000 miles. Dealer states the sealed LED unit is non-serviceable and must be replaced as a complete assembly, quoted at ~$1,450. LED headlights are rated for tens of thousands of hours and are marketed to last the life of the vehicle; this failed at a small fraction of rated life. Other 2023 Enclave owners report the same right-side failure at similar low age/mileage, suggesting a recurring defect.

   Headlight on right side failure - no light. AI shows a recall for this problem, but my vin was not listed. Notice also states 2022, 2023, and 2024 vehicles. It should be as car was only 2 years 10 months old with about 42000 miles. GM has the part now. Dealer inspected the car. Light had less then 750 hours on it; references say average light should last 20,000 hours. An obvious defect. Only noticed failure due to a neighbor seeing it. We drive mostly in the day due to age. Car is used only to go to work. Car has auto headlights, and they do not operate during daylight when we drive.

    In Driver info center messages displayed are ESC “this is anti lock cracking system not working”. Steering assist reduced “this is lane departure steering assist not working” Parking brake. “not working” Also cruise control is not working Buick service tells me this has happened often enough in other vehicles that there is a repair bulletin on it. Also the initial cost to repair is $3000 + if this bulletin repair fixes the problem if not there would be more costs. This vehicle is within the 36 month bumper to bumper warranty period but has recently exceeded the 36000 mile warranty threshold. I have already paid for the initial part so it could be ordered.

    The car stalled and is stuck in park. It has electronic shift and if the engine doesn't run it has to be put into neutral manually. The Buick dealerships don't know how to do this and keep referring me to an obsolete video. One service representative suggested the manual lever is under the air filter housing but they cannot provide any information on this design, The car is stuck in a garage and cannot be towed. It is stuck in place.

    The headlights on our 2023 Buick Enclave do not provide nearly enough light at night. If you shine the lights up against a wall at night they seem bright but they do not seem to light up the area directly in front of the car. When driving on a road without streetlights at night I barely feel like my headlights are on. It’s so bad that I am concerned that if a person or an animal stepped out in front of my car I wouldn’t be able to see it in time to avoid it. I brought the car into the dealer today and they actually found that both headlights need to be raised 11-12 inches (they were completely shocked). This is very odd for a new car with only 5k miles. Unfortunately, raising the headlight did not add more light in front of the car at night. I think the issue is caused by the headlights not only being very small but also because they are very low on the car. Also, the headlights are below the grill and the running lights are on the hood. I believe this could be a design flaw that is also a safety hazard. A mechanic at the dealer also agreed with me that in general the lights are very dim. If you drive this model car at night on a road with no street lights I bet you will come to the same conclusion. Attached is the invoice from today that shows the headlights had to be raised. I told the dealer that they should pull another enclave off their lot and see if the issue is only present in my car or if the headlights on other enclaves need to be raised.

    The vehicles low beams fail to properly illuminate the road, and create a significant blind spot in your vision. We bought a brand new 2023 Buick Enclave and noticed on the first night drive that the vehicles lighting has a very large blind spot where it fails to properly illuminate the road. When switching too high beams the blind spot is diminished but not eliminated. We immediately took the vehicle back to the dealer where they adjusted the lights. However, all that they accomplished was to move the blind spot more central to the vehicle. When traveling up or down hills the lighting problem changes. When traveling up a hill the blind spot is moved closer to the vehicle creating a larger hazard. Traveling down hill the lighting blind spot is moved a bit further out. This is truly a very big safety concern especially when around pedestrians at night as it is nearly impossible to seem them until the very last second. The lighting problem and safety is worse when traveling at higher speeds as you have no time react when things suddenly appear from a blind spot in the vehicles head lights. I have attached several pictures. Please get in contact with me if you have further questions. All attached photos have been taken with an iPhone 13 and have no visual enhancements.
