Mercedes-Benz Cases Under Massachusetts Lemon Law

Mercedes-Benz has substantial Massachusetts market share — particularly in the Greater Boston luxury market. Mercedes cases are pursued under § 7N½ (Massachusetts Lemon Law) and Chapter 93A.

Common Mercedes defect patterns

• 9G-Tronic transmission shift issues.
• M256 inline-6 oil consumption.
• M276 V6 / M278 V8 balance shaft / oil consumption.
• AdBlue (DEF) system failures (diesel models).
• Airmatic suspension failures.
• EQS / EQE / EQB BMS, OTA firmware issues.
• MBUX infotainment crashes.
• Sprinter diesel emissions failures.
• G-Wagen electrical / suspension issues.

EQ-series EV patterns

• BMS firmware bugs.
• OTA update failures.
• Charge port reliability.
• Range degradation in cold weather.

Sprinter coverage limitation

Most Sprinter configurations exceed Massachusetts’s 10,000-lb GVWR threshold — must be pursued under c. 93A and Magnuson-Moss only.

Mercedes TSB / recall overlay

Heavy TSB pattern:

• 9G-Tronic shift reflash TSBs.
• M256 oil-consumption TSBs.
• AdBlue system TSBs.
• MBUX firmware updates.
• EQ-series OTA history.

Chapter 93A willfulness fit

Mercedes cases support c. 93A willfulness particularly with:

• 9G-Tronic class-action history.
• AdBlue system pattern.
• M256 oil-consumption pattern.

Bottom line

Mercedes cases are strong Massachusetts candidates given the affluent Greater Boston luxury market. AdBlue diesel emissions and 9G-Tronic transmission patterns provide strong c. 93A willfulness evidence.
