Driving a 2016 Buick Lacrosse offers a blend of comfort, technology, and American refinement that is hard to ignore. This full-size sedan was designed to compete with the best in its class, providing a quiet cabin and smooth ride. However, like any complex machine, specific 2016 Buick Lacrosse problems have surfaced over the years that owners and potential buyers need to be aware of.
Overview of the 2016 Model Year
The 2016 Buick Lacrosse entered the market as a mature model in the brand’s lineup, featuring a refined interior and updated safety features. It was offered with a choice of a fuel-efficient four-cylinder or a more powerful V6 engine. While the vehicle performed well in initial reviews, the long-term reliability has been a topic of discussion among automotive forums and consumer reports.
Common Electrical and Infotainment Issues
One of the most frequently reported 2016 Buick Lacrosse problems involves the infotainment system and electrical glitches. Owners have experienced random resets of the radio, unresponsive touchscreens, and occasional failure of Bluetooth connectivity. These issues can often be traced to software bugs or faulty wiring harnesses that require dealer attention to resolve properly.
Navigation and Audio System Failures
The navigation system, in particular, has been a point of frustration for some drivers, with GPS signal loss or incorrect routing being common. Audio system failures, such as sudden loss of sound or static interference, also appear more often than in similar vehicles from this era. These electronic gremlins, while not safety-critical, significantly impact the daily driving experience.
Engine and Transmission Reliability Concerns
Under the hood, the 2016 Lacrosse’s 2.5L four-cylinder engine has been known to develop oil consumption issues over high mileage. Some owners have reported using excessive amounts of oil between changes, which, if neglected, can lead to premature engine wear. The six-speed automatic transmission generally performs well but can exhibit harsh shifting in certain driving conditions.
V6 Performance and Fuel Economy
For those who opted for the 3.6L V6, the power delivery is strong, but fuel economy tends to be lower than advertised. Additionally, a minor number of complaints involve the timing chain, where unusual rattling noises may appear as the vehicle ages. Regular maintenance and using the correct oil viscosity are key to mitigating these risks.
Interior Wear and Tear
Another set of 2016 Buick Lacrosse problems relates to the interior components. The materials used are generally high quality, but plastics can become brittle over time, leading to cracks around the dashboard and center console. Seat upholstery, particularly in higher trims, may show signs of wear or develop small tears with heavy use.
Climate Control and Switch Malfunctions
Some owners have noted that the climate control buttons can fail, resulting in loss of heating or cooling in specific zones. This is often due to worn switches behind the panel. While not a dealbreaker, it can be an inconvenience that requires dealer service or aftermarket replacement parts to fix.
Safety System Notifications and Recalls
The 2016 model year was subject to several manufacturer recalls, many of which were related to safety systems. These included issues with the backup camera, stability control software, and seat belt pretensioners. It is crucial for current owners to verify with their local Buick dealer whether their vehicle has completed all outstanding recall work.
Checking Vehicle History
When considering a used 2016 Buick Lacrosse, running a detailed vehicle history report is essential. Look for records of accident damage, odometer rollback, and previous repair work. A well-maintained example with service records will likely have fewer surprises than one that has been neglected.
