Buick has long been a staple of American automotive history, delivering a blend of comfort, affordability, and performance. However, not all models have stood the test of time. Some have been plagued by reliability issues that can drain your wallet with costly repairs. If you’re in the market for a used Buick, here are ten models to approach with caution.

Buick Enclave (2008-2017)

The Buick Enclave debuted with high expectations, promising a roomy interior and a powerful V6 engine. But beneath its premium exterior lurked a notorious issue: timing chain problems. Owners reported premature wear, leading to expensive repairs that often exceeded several thousand dollars. What’s worse? If neglected, this failure could mean catastrophic engine damage.

Buick Rendezvous (2002-2007)

Buick’s attempt at an SUV-crossover hybrid resulted in the Rendezvous, a model that never quite found its footing. Common complaints include transmission failures and persistent electrical issues that left many drivers stranded. The automobile stands as a cautionary tale as one of several Buick missteps best left in the rearview mirror.

Buick LaCrosse (2005-2009)

Though competitively priced when new, early LaCrosse models revealed long-term flaws. Power steering systems were prone to leaks, leading to compromised handling, and transmission issues surfaced sooner than expected. Even attentive owners faced major repair costs. For used car buyers, a better-maintained sedan from the same era offers more peace of mind.

Buick Park Avenue (1997-2005)

Once seen as a flagship luxury sedan, the Park Avenue’s final years were plagued by electrical malfunctions and aging suspension systems. As replacement parts grow harder to source, repair costs continue to climb. Anyone considering this model should prioritize a thorough electrical inspection before committing.

Buick Regal (2011-2017)

The Regal aimed for sportier performance, but turbocharger failures and excessive oil consumption plagued this generation. Owners found themselves dealing with unpredictable power loss and steep repair bills, which made the model a risky investment. In fact, as turbo technology improves, automakers are addressing the reliability concerns that tarnished early designs like this Regal.

Buick Century (1997-2005)

While affordable and spacious, this model had one major flaw: the intake manifold gasket. When it failed, coolant leaked into the engine, causing costly and sometimes permanent damage. When considering a Century, be sure to confirm gasket replacements with service records; otherwise, expect potential engine trouble.

Buick Verano (2012-2017)

Buick’s attempt at a compact luxury sedan was undermined by transmission issues and poor fuel economy. Drivers also reported inconsistent shifting, unexpected loss of acceleration, and lackluster efficiency. Given its track record for performance flaws and high fuel costs, this is one compact sedan you’re better off avoiding.

Buick Encore (2013-2015)

Early versions of the Encore struggled with reliability, especially under the hood. Engine problems and premature turbocharger failures were common complaints, often leading to sudden power loss or sluggish acceleration. Repairs didn’t come cheap either. While newer models show improvement, these early-year Encores remain a high-risk pick on the used market.

Buick LeSabre (1998-2005)

The LeSabre was a spacious, comfortable cruiser, yet it suffered from fuel pump failures and transmission problems. Owners faced frequent breakdowns, making this model more frustrating than functional. It is advisable to avoid used LeSabres with unclear maintenance histories, as transmission repairs can be costly.

Buick Envision (2016-2018)

Buick introduced the Envision with hopes of competing in the premium SUV market. However, its infotainment system glitches and transmission hesitation tarnished its reputation. Unless you enjoy wrestling with touchscreen tantrums and second-guessing your gear shifts, steer clear of this “premium” misfire.
