Yes, some Buick Regals have reported transmission problems, particularly in certain model years and engine configurations, but many Regals operate normally with proper maintenance. The risk varies by generation and how well the car has been cared for.
Overview: Buick Regal transmissions
The Buick Regal has spanned multiple generations with different transmissions over the years. The later, more common Regals (around 2011–2017) used GM’s 6-speed automatic transmissions, often paired with a 2.0-liter turbo engine or a 2.4-liter naturally aspirated engine. Transmission behavior and reliability can vary by year, trim, and maintenance history. As with many mid‑cycle GM vehicles, reports of shifting quirks or failures tend to be concentrated among specific configurations rather than across the entire lineup.
Common transmission issues reported
Below are the symptoms and problems most frequently discussed by owners and reviewers. The items describe what you might encounter rather than a universal failure across every Regal.
- Transmission shudder or hesitation at low speeds or during light acceleration
- Delayed engagement or rough shifts when moving from Park to Drive
- Torque converter-related problems, including slipping or overheating leading to limp mode
Whether you encounter these issues depends on the exact model year, engine choice, maintenance history, and how the vehicle has been driven. If you notice any of these signs, a diagnostic from a qualified shop is recommended, ideally sooner rather than later to avoid further damage.
Model years and configurations to watch
Not all Regals are equally affected. The most commonly reported transmission concerns tend to involve the later mid‑2010s Regals with the 2.0L turbo engine and the associated 6‑speed automatic, but reports do exist across other generations as well. Prospective buyers and used‑car shoppers should pay particular attention to the vehicle’s service history and any recalls or service bulletins related to the transmission system.
- Regals produced roughly between 2011 and 2017, especially those with the 2.0L turbo engine paired to a 6‑speed automatic, are the most frequently cited in owner discussions about transmission behavior.
- Earlier generations (pre-2011) used different transmissions and have their own sets of potential issues; they are less commonly discussed in recent transmission complaint channels but are not immune.
In all cases, an independent pre‑purchase inspection, a test drive that probes shifting at multiple speeds, and a review of any GM service bulletins or recalls can reveal whether a particular Regal is likely to face transmission trouble.
Summary
The Buick Regal’s transmission reliability varies by generation, engine, and maintenance history. While some owners report shifting quirks or failures—especially in mid‑2010s Regals with the 2.0L turbo—others experience trouble‑free operation. If you’re considering a used Regal, check maintenance records, look for any transmission‑related recalls or service bulletins, and have a trusted mechanic perform a thorough inspection and diagnostic test. Note that Buick discontinued the Regal in North America after the 2017 model year, so used examples may be older but remain available on the market.
