Used Buick Buying Guide: Models to Buy and Avoid
Buick used car guide covering Enclave, Encore, Envision, LaCrosse. Reliability data, common problems, and recommended model years.
Buick sits in GM’s luxury-adjacent tier — positioned above Chevrolet and below Cadillac — and used Buick reliability reflects that middle ground. RepairPal rates Buick 3.5 out of 5.0 with $608 in average annual repair costs, slightly below the industry average of $652. That makes Buick one of the more affordable GM brands to maintain long-term.
The catch is platform sharing. Every Buick rides on a Chevrolet platform with the same engines and transmissions. The Enclave shares GM’s C1XX platform with the Chevrolet Traverse and Cadillac XT5. The Encore shares the Gamma II platform with the Chevrolet Trax. The mechanical reliability is identical — Buick adds quieter cabins, softer suspensions, and higher trim levels.
This guide covers used Buick reliability data, the best and worst model years, common problems across the lineup, and which models deliver the best value on the used market.

Buick’s reliability story depends entirely on which platform and model year you’re buying. The 2008-2017 Enclave on the Lambda/C1XX platform has well-documented transmission problems. The 2013-2016 Encore on the Gamma II platform shares the Chevy Trax’s turbo and transmission issues. The 2018+ models across the lineup improved significantly.
Which Buick Models Should You Consider?
Enclave is Buick’s three-row SUV and the most popular used Buick on the market. The 2018-2024 second generation resolved the transmission problems that plagued the 2008-2017 first generation. Read the full Buick Enclave years to avoid guide for model-by-model breakdowns.
Encore is Buick’s subcompact SUV competing with the Honda HR-V and Mazda CX-3. The 2017-2022 models are the sweet spot — the 1.4L turbo engine matured, and the Gamma II platform’s early problems were resolved.
Envision bridges the gap between Encore and Enclave. The 2021+ second generation on the E2XX platform is a genuinely competitive compact SUV with strong reliability data. The 2016-2020 first generation was built in China with mixed quality reports.
Best Used Buick Years to Buy
- Enclave: 2020-2024 (mature second generation, all major issues resolved)
- Encore: 2017-2022 (refined Gamma II platform, turbo reliability improved)
- Envision: 2021-2024 (US-designed second generation, new platform)
- LaCrosse: 2017-2019 (final years, mature platform, luxury sedan value)
Buick Years to Avoid
- Enclave 2008-2013: Transmission failure at 80,000-120,000 miles, timing chain stretch, AC compressor failure
- Encore 2013-2015: Turbo oil feed line leaks, transmission shudder, electrical gremlins
- Envision 2016-2018: First-generation quality concerns, parts availability issues
The bottom line on used Buick reliability: buy the 2018+ models and you get GM mechanicals with a quieter, more refined package at significant depreciation discounts. The used car buying guide principle applies — always check NHTSA complaint counts before committing to any specific Buick model year.
