Buick Avenir: A Comprehensive Guide

The Buick Avenir isn't a model, but a sub-brand representing the pinnacle of luxury within the Buick lineup. Introduced as a concept car in 2015 and first launched with the 2018 LaCrosse, Avenir signifies the highest trim level available, featuring enhanced styling, premium materials, and additional comfort and convenience features compared to standard Buick models. Avenir aims to provide a near-luxury experience at a more accessible price point than traditional luxury brands. Positioned to compete with upper-tier trims from mainstream brands and entry-level luxury vehicles, the Avenir sub-brand has been applied to several Buick models, including the LaCrosse, Enclave, Encore GX, and Envision.

Reliability & Common Issues

The reliability of Buick Avenir models is generally considered good, aligning with the overall reputation of Buick. However, like any vehicle, certain issues can arise, particularly as models age.

General Issues (Applicable to most Avenir Models):

Infotainment System Glitches: Some owners have reported occasional glitches with the infotainment systems, including screen freezes, connectivity issues, and delayed responses. Software updates often address these problems.

Sensor-Related Issues: Advanced driver-assistance systems rely on sensors, and malfunctions with these sensors (e.g., parking sensors, blind-spot monitoring) can occur. Recalibration or replacement may be necessary.

Electrical System Problems: Intermittent electrical issues, such as battery drain or malfunctioning accessories, have been reported in some cases.

Specific Model Issues:

LaCrosse Avenir (2018-2019): The 9-speed automatic transmission could experience rough shifting in early production years. Check for transmission recalls and ensure proper fluid levels and maintenance.

Enclave Avenir (2018-Present): Water leaks, particularly around the sunroof, have been a recurring issue. Inspect the headliner and carpets for signs of water damage. Some owners have also reported issues with the automatic emergency braking system.

Encore GX Avenir (2020-Present): The turbocharged three-cylinder engines are generally reliable, but some owners have reported issues with the CVT transmission, including hesitation and jerky acceleration. Regular CVT fluid changes are crucial.

Envision Avenir (2021-Present): The Envision Avenir, being a newer model, has fewer reported issues. However, as with other modern vehicles, software glitches and electronic component failures can occur.

Important Note: Always check for recalls and Technical Service Bulletins (TSBs) related to specific models and years before purchasing. A pre-purchase inspection by a qualified mechanic is highly recommended to identify any potential problems.

Driving Experience

Pros:

Comfortable Ride: Avenir models are known for their smooth and comfortable ride, thanks to well-tuned suspensions and quiet cabins.

Refined Interior: Premium materials and upscale design create a luxurious and inviting interior environment.

Abundant Features: Avenir trims come loaded with features, including advanced safety technologies, connectivity options, and convenience amenities.

Quiet Cabin: Buick's QuietTuning technology effectively minimizes road and wind noise, enhancing the driving experience.

Value Proposition: Avenir offers a near-luxury experience at a more accessible price point than traditional luxury brands.

Cons:

Not a Performance Vehicle: While Avenir models offer adequate power, they are not designed for performance driving. Acceleration and handling are geared towards comfort and refinement rather than sportiness.

Infotainment System Complexity: The infotainment system, while feature-rich, can be complex and require a learning curve.

Potential for Higher Maintenance Costs: The advanced features and premium components of Avenir models can translate to higher maintenance and repair costs compared to base models.

Some Interior Plastics: While generally upscale, some Avenir models may still have some areas with less premium plastic trim, which can detract from the overall luxury feel.

Buying Advice

Years to Look For:

For the LaCrosse Avenir: The 2019 model may be slightly preferable due to minor refinements over the 2018 model. Ensure any potential transmission issues have been addressed.

For the Enclave Avenir: The 2022 and newer models offer significant improvements in styling, technology, and ride quality. Earlier models (2018-2021) can be a good value if well-maintained, but be mindful of potential water leak issues.

For the Encore GX Avenir: The 2024 and newer models are highly recommended due to the extensive redesign and improved technology.

For the Envision Avenir: The 2021 and newer models are a solid choice, but consider waiting for future model years for potential technology updates and feature enhancements.

Years to Potentially Avoid (or Proceed with Caution):

Early Production Years: With any new model or major redesign, early production years (e.g., 2018 LaCrosse Avenir, 2018 Enclave Avenir) may have a higher likelihood of minor issues that were addressed in later model years.

Models with Known Issues: Be particularly cautious when considering models with known issues, such as the Enclave Avenir with potential water leaks. Thoroughly inspect the vehicle and address any concerns before purchasing.

Vehicles with Neglected Maintenance: Regardless of the model year, avoid vehicles with a history of neglected maintenance. Proper maintenance is crucial for the longevity and reliability of any vehicle, especially those with advanced features and complex systems.

General Buying Tips:

Thorough Inspection: Conduct a thorough inspection of any Avenir model you are considering, paying close attention to the interior, exterior, and mechanical components.

Pre-Purchase Inspection: Have a qualified mechanic perform a pre-purchase inspection to identify any potential problems.

Check Vehicle History: Obtain a vehicle history report (e.g., Carfax, AutoCheck) to check for accidents, title issues, and maintenance records.

Test Drive: Take the vehicle for an extended test drive to assess its performance, handling, and comfort. Pay attention to any unusual noises, vibrations, or shifting issues.

Negotiate Price: Research the market value of similar Avenir models and negotiate the price accordingly. Be prepared to walk away if the price is not right.

Review Warranty Coverage: Understand the remaining warranty coverage (if any) and consider purchasing an extended warranty for added peace of mind.
