Buick’s current lineup is all crossovers, and its defect patterns track the General Motors platforms underneath them. The complaints that reach us most often involve transmissions, small-displacement turbo engines, and electronics shared across the GM family. Model-by-model detail is on our Buick problems and recalls hub.
The Enclave has a documented history of transmission shudder and harsh shifting complaints, along with the timing-chain wear issues that dogged earlier 3.6-liter V6 GM applications. The smaller Encore and Encore GX draw complaints about their turbocharged three- and four-cylinder engines — coolant loss, stalling, and start-stop behavior — and Buick models have appeared repeatedly in GM’s brake-assist, backup-camera, and daytime-running-light recall campaigns.
Buick’s warranty is four years or 50,000 miles bumper-to-bumper with six years or 70,000 miles of powertrain coverage — better than the GM norm, and a longer window for repeat-repair documentation. If your Buick keeps returning to the dealer for the same complaint, keep every repair order; the pattern is the case.
If your Buick has been in the shop repeatedly for the same warranty problem, or has spent weeks out of service, you may have a lemon law claim. Get a free case review — it costs nothing unless we recover for you.
