Toyota Cases Under Massachusetts Lemon Law

Toyota (including Lexus) has substantial Massachusetts market share — particularly RAV4, Tacoma, Tundra, Highlander, Sienna, Camry, Corolla, and the Prius/Crown hybrid families. Toyota cases are pursued under § 7N½ (Massachusetts Lemon Law) and Chapter 93A.

Common Toyota defect patterns

• V35A / V6 engine fuel pump failures (broader recall scope).
• Hybrid system failures — battery, inverter, transaxle issues.
• 8AT transmission shifting issues.
• Toyota Safety Sense (TSS) defects — Pre-Collision System false alarms.
• DRCC (Dynamic Radar Cruise Control) glitches.
• Tacoma rear differential failures.
• Tundra V6 turbo issues (3.5L TT).
• TRD Pro lift-related suspension defects.
• Infotainment crashes (Toyota Audio Multimedia).
• Cold-weather hybrid battery issues (relevant in MA).

Lexus-specific patterns

• NX / RX hybrid system defects.
• LS500 / GS300 / GS350 transmission issues.
• IS500 / RC F engine issues.

Toyota TSB / recall overlay

Toyota has extensive TSB documentation. Heavy recall patterns recently:

• V35A fuel pump (multiple recalls).
• TSS calibration updates.
• Hybrid battery TSBs.
• Infotainment software updates.

Chapter 93A willfulness fit

Toyota cases support c. 93A willfulness when:

• Pattern affects multiple model years.
• Recall / TSB demonstrates manufacturer awareness.
• Customer-relations denials show systemic conduct.

Bottom line

Toyota cases are strong Massachusetts Lemon Law candidates. Document the TSB / recall pattern carefully and pursue c. 93A in court when willfulness is in play. The § 9(3) demand letter framework produces strong pre-suit pressure given Toyota’s recall history.
