Overview

2011 Buick Regal

The 2011 Buick Regal presents a compelling, if flawed, option for used car shoppers. It offers a comfortable ride and a touch of premium feel, but this comes with a notable asterisk regarding its long-term dependability. With 6 recalls and over 400 complaints logged with NHTSA, potential buyers must be aware of its documented weaknesses, particularly in the powertrain and electrical departments. The 2.0L four-cylinder engine, while capable, is a frequent source of owner complaints, often manifesting as stalling or power loss. Electrical system gremlins are also common. Fuel economy is respectable for its class, achieving a combined 21 MPG. However, the significant reliability concerns mean a careful inspection is paramount.

Critical Failure Risk

A significant number of complaints point to the engine stalling unexpectedly or losing power during operation. This can be related to fuel delivery, ignition system faults, or internal engine issues.

Early detection can help you avoid a $1,500-$3,500 repair.
