What Owners Say

Rough shifting

"Started within the first 5000 miles. Shifting was balky and shifted hard."

Anonymous, TX (2018 Buick Enclave Avenir 3.6-L V6)

"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."

"occasionally seems to have trouble sliding into next gear"

"The problem was rough shifting in the lower gears primarily when the transmission fluid was hot (>185Â°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."

Slipping transmission

"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."
