In short: there isn’t a single “bad” year for the Buick LaCrosse, but the earliest model year (2005) is most commonly cited as having more reliability issues, while later generations generally improve. If you’re shopping used, pay extra attention to maintenance history and any recall status.
The Buick LaCrosse spanned two generations before the model was discontinued after the 2016 model year. Understanding how reliability varies by generation can help buyers identify years that may warrant closer inspection. This article examines reliability trends, common risk factors, and practical steps for prospective buyers.
Reliability by generation
The LaCrosse arrived as a new full-size sedan in 2005 and ran through 2009 as the first generation. A redesigned second generation followed from 2010 to 2016, with some models offering the eAssist mild-hybrid system. Overall, owners and reviewers tend to regard the second-generation cars as more consistent in reliability, though no year is completely exempt from recalls or repairs.
First generation (2005–2009)
The early years of the LaCrosse are where reliability concerns were most frequently reported. Buyers considering these model years should pay particular attention to maintenance history and any recall work that may have been performed. While some owners report solid performance, the concours of complaints in this range makes it the area where risk is relatively higher for a used purchase.
Before reviewing specific years, here is a general takeaway: the oldest LaCrosse models are more likely to show wear from past use and may require more extensive service in areas such as transmission tuning, electrical systems, and cooling components. A careful pre-purchase inspection and verification of recall completion can mitigate many potential issues.
- Overall reliability tends to be lower in the 2005–2009 range compared with the later generation, due to the car’s early-production status and the typical teething problems that come with a new platform.
- Maintenance history and recall completion are especially important for these years; verify service records and any dealership-recommended repairs.
In short, the first-generation years are the ones most commonly flagged as riskier for used LaCrosse buyers, primarily due to early-generation reliability variances.
Second generation (2010–2016) and notable variants
The 2010 redesign generally brought improved reliability and updated features, with some years offering the gas V6 or the eAssist hybrid variant. While these models tend to be more dependable than the earliest LaCrosse, there are still recalls and specific issues to watch for, depending on the exact year and configuration.
For shoppers, the key takeaway is that the second-generation cars overall improve on the first generation, but they are not immune to recalls and model-specific faults. Checking the recall status and obtaining a clean vehicle history remains essential.
- The 2010–2016 second-generation cars are typically more reliable than the 2005–2009 models, but individual years vary due to recalls and maintenance histories.
- Some models, including eAssist variants, have their own unique service considerations; always verify the specific year’s known issues and any factory campaigns.
Overall, if you’re weighing a LaCrosse, the second-generation cars are generally safer bets for reliability, provided you verify recall work and maintenance records for the exact year.
Practical checks when shopping used
To minimize risk, buyers should conduct targeted checks regardless of year. A structured approach helps uncover hidden problems and confirm the car’s upkeep history.
- Check recall status and ensure all campaigns have been completed before purchase.
- Request full maintenance records, focusing on transmission service, cooling system work, and electrical repairs.
- Inspect for signs of corrosion, leaks, or abnormal wear around the engine, transmission, and suspension components.
- Test drive to evaluate transmission behavior, engine response, steering feel, and electrical accessory operation.
- Have a trusted mechanic perform a pre-purchase inspection with a focus on the cooling system, braking system, and reliability-critical components.
These checks help balance the advantages of the LaCrosse’s spacious interior and comfortable ride against the potential drawbacks of older or less-maintained examples.
Summary
The Buick LaCrosse does not have a single “bad” year; however, the 2005–2009 models are generally viewed as the more problematic early lineup, while the 2010–2016 second generation offers improved reliability on average. For any used LaCrosse, the most important steps are verifying recall completion, obtaining complete maintenance records, and conducting a thorough pre-purchase inspection. A well-maintained second-generation LaCrosse can offer a dependable, comfortable ride, but diligence remains essential when evaluating model years.
