Buick Lemon Law Lawyers

Buick’s turbocharger failures in models like the Encore, Envision, and Regal create compelling lemon law cases because they affect fundamental vehicle performance and often occur despite proper maintenance, contradicting Buick’s typical defense. Common symptoms include power loss, excessive exhaust smoke, oil consumption, check engine lights, and limp mode activation. What makes these cases notable is that turbocharger replacements frequently fail to resolve underlying design issues with oil delivery systems and heat management. For successful turbocharger-related lemon law claims, document all performance impacts, diagnostic trouble codes, and especially any dangerous highway merging situations caused by sudden power loss. Buick (as part of GM) often employs a defense strategy of performing partial repairs rather than addressing systemic design deficiencies, which actually strengthens the repeat repair evidence required for lemon law qualification.

Buick’s eAssist mild hybrid system creates distinctive lemon law considerations because its integration with standard powertrain components means failures affect conventional engine and transmission operation in LaCrosse, Regal, and other models. When hybrid system problems emerge, Buick typically defends by classifying these as auxiliary features rather than essential powertrain components, despite their impact on basic vehicle operation. To strengthen your claim, document specifically how hybrid system malfunctions affect overall vehicle performance, particularly noting instances of reduced power, stalling, or battery system warnings. Buick’s own technical service bulletins regarding eAssist battery monitoring and control module calibration provide evidence of known system vulnerabilities. Expert testimony establishing the interconnected nature of hybrid and conventional powertrain components is particularly effective in establishing that these issues substantially impair vehicle use despite Buick’s attempts to minimize their significance by compartmentalizing systems. Several courts have found that hybrid component failures qualify for lemon law protection when they impact basic vehicle operation.

Buick vehicles equipped with automatic start-stop systems, particularly Encore, Envision, and Regal models, have experienced specific defect patterns that strengthen lemon law claims. These vehicles may exhibit symptoms including failure to restart after stopping, extended cranking periods, battery depletion requiring jump starts, and erratic operation in normal traffic conditions. Buick typically defends by performing software updates rather than component replacements, often attributing problems to driver behavior or environmental factors despite repeated failures in normal operating conditions. To build a strong case, document all system failures chronologically, noting safety implications when the vehicle fails to restart in traffic situations, and maintain records of any battery replacements required due to excessive cycling. Buick’s technical service bulletins regarding start-stop disable criteria and battery management strategies provide evidence of known issues. Courts in several states have found that unreliable restart functionality meets the ‘substantial impairment of safety’ standard, as unexpected immobility in traffic creates clear hazards regardless of the manufacturer’s position that the feature is supplemental rather than essential.

Buick vehicles equipped with active noise cancellation (ANC) systems, particularly Enclave, Envision, and LaCrosse models, have experienced specific defect patterns that strengthen lemon law claims. These vehicles may exhibit symptoms including unusual cabin resonance or drone at specific speeds, system-generated noise exceeding the sounds it attempts to cancel, microphone or speaker failures affecting system operation, and complete system malfunction requiring module replacement. Buick typically defends by performing software updates rather than component replacements, often claiming the noise characteristics represent normal operation despite clearly abnormal acoustic patterns. To build a strong case, document noise issues with audio recordings comparing your vehicle to identical models without the defect, note specific speeds or operating conditions that trigger the problems, and maintain records of all attempted repairs. Buick’s technical service bulletins regarding ANC calibration procedures provide evidence of known issues. While Buick often argues comfort features are subjective rather than defective, courts in several states have found that technology packages commanding significant price premiums meet the ‘substantial impairment of value’ standard when they consistently fail to deliver advertised capabilities or create worse conditions than if the system were absent entirely.
