What Owners Say
"Auto stop when at an intersection should be removed! Unnecessary and useless. Maybe save $5 a year in gas if that. If you accelerate rapidly when at Auto stop, car will clunk badly. Also when accelerate rapidly while driving normally, you can feel the transmission abruptly switching gears."
Anonymous, IN (2018 Buick Enclave Essence 3.6-L V6)"occasionally seems to have trouble sliding into next gear"
Anonymous, FL (2018 Buick Enclave Essence 3.6-L V6)"early 2018 enclaves has a problem with the transmission. This was taken care of by changing out the transmission fluid. No problems since."
Anonymous, FL (2018 Buick Enclave Premium 3.6-L V6)"The problem was rough shifting in the lower gears primarily when the transmission fluid was hot (>185°F). The fluid was changed (not sure if anything else was done) and that resolved the issue. The technician speculated it was premature breakdown of the transmission fluid."

Anonymous, MI (2018 Buick Enclave Premium 3.6-L V6)"transmission had contaminated oil which had to be replaced also a wire harness had to be replaced while out of town.. problem caused the car to shutter after coming to a complete stop then accelerating a head."
Anonymous, IL (2018 Buick Enclave Avenir 3.6-L V6)"The case of the transmission cracked and leaked causing performance problems. After several service visits this was identified and repaired. The vehicle still did not drive correctly and as time went the vehicle that the dealer thought drove fine again began rough shifting and slipping. A solenoid valve was malfunctioning in the transmission. It has taken everal very long service periods to get these issues fixed. If I owned the car I would sell it."
