2024 Chevrolet Corvette Lemon Law Case Study — New Hampshire
A 2024 Chevrolet Corvette Plagued by Convertible Top and Electronic Defects
Our client purchased a new 2024 Chevrolet Corvette in New Hampshire — a flagship American sports car that should deliver premium performance and reliability. Instead, by just 4,379 miles the car began exhibiting a recurring transmission control module fault and a convertible top latch failure that repeatedly locked the owner out of the trunk and prevented the top from operating correctly.
Over the course of five separate repair attempts, the authorized Chevrolet dealership replaced the serial data gateway module, the left folding top control module, the left hatch assembly, and the center console latch push-button — and still could not permanently resolve the convertible top latch defect. The owner contacted Easy Lemon after the fourth failed repair.
What Went Wrong
- Check engine light with TCM fault (DTC U1608): Diagnosed as an internal failure of the serial data gateway module — replaced and programmed, yet electronic warnings continued to surface
- Convertible top latch failure: The top would not latch, the window would not automatically roll back up, and the trunk could not be opened — a critical use-and-value defect in a convertible
- Recurring failures after multiple module replacements: Left folding top control module, left hatch assembly, and header latch adjustments all failed to eliminate the issue
- Interior defects: Center console button failure and a deformed driver’s side sun visor (buckled suede leather) added to the vehicle’s substantial impairment
Five Visits Could Not Resolve the Defects
Visit 1 — February 7–11, 2025 (5 Days)
- Check engine light and instrument panel concerns reported
- Technicians found DTC U1608 stored in the transmission control module and diagnosed an internal fault in the serial data gateway module
- The module was replaced and programmed
Visit 2 — August 7–18, 2025 (12 Days)
- Convertible top would not latch, window would not roll back up, and the trunk could not be opened
- Code B19E4-64 stored; GM bulletin #21-NA-192 procedure performed but the issue persisted
- Left folding top control module diagnosed as an internal failure — replaced and programmed
- Center console latch push-button assembly also replaced for a faulty button
Visit 3 — August 19–23, 2025 (5 Days)
- Convertible top once again failed to latch — returned to dealer the day after pickup
- Code B19E7-64 stored; traced to the left convertible top header latch switch
- Left hatch assembly replaced; GM technical assistance case opened when issue persisted; header latch adjusted per guidance
Visit 4 — September 3–8, 2025 (6 Days)
- Convertible top failure reported again
- Technicians found the right roof header latch sensor was over-traveling and realigned the upper right header latch
- Driver’s side sun visor confirmed to have buckled suede leather — new visor on backorder from GM
Visit 5 — September 16, 2025 onward
- Vehicle returned again for the same recurring convertible top issue
- Despite four prior repairs, the latch/header assembly defect remained unresolved
- At this point a lemon law claim was the only path to a permanent remedy
Why This Chevrolet Corvette Qualified for a Full Buyback
The 2024 Corvette is Chevrolet’s halo performance car — a vehicle consumers purchase for exceptional build quality, precision engineering, and dependability. A recurring convertible top latch failure that blocks trunk access and a TCM-related communication fault strike at the core of the vehicle’s use, value, and safety.
This case presented several compelling legal factors:
- New Hampshire Lemon Law eligibility: RSA 357-D protects owners of new motor vehicles with a nonconformity that substantially impairs the vehicle’s use, market value, or safety — typically after three or more unsuccessful repair attempts for the same defect, or 30+ cumulative business days out of service during the warranty term. This Corvette was out of service for 28+ documented days across four visits before the fifth attempt.
- Pattern of failed repairs: Four module replacements, header latch adjustments, and GM TAC escalation all failed to eliminate the convertible top defect — a textbook pattern of substantial impairment
- Critical use defect: A convertible whose top will not latch and whose trunk will not open cannot serve its fundamental purpose; this defect weighs heavily in any buyback demand
- Documented diagnostic evidence: Stored DTCs U1608, B19E4-64, and B19E7-64, plus a formal GM Technical Assistance case, created a strong contemporaneous record of the defects
- Federal Magnuson-Moss Warranty Act: Repeated warranty repairs on a nonconformity Chevrolet could not permanently fix also triggered a federal breach-of-warranty claim, providing additional leverage against General Motors LLC

Free Case Evaluation
We reviewed the complete repair history, confirming five separate documented service events for the same core convertible top latch defect plus an earlier TCM/gateway fault — all within the first year of ownership.
Documentation & Case Building
Our team compiled every repair order, stored DTC, replaced part number, GM Technical Assistance case note, and the sun visor backorder record to build an airtight timeline showing GM’s inability to permanently repair the vehicle.
Demand to General Motors
We filed a formal demand against General Motors LLC citing the New Hampshire Lemon Law (RSA 357-D) and the federal Magnuson-Moss Warranty Act, documenting five failed repair attempts and the ongoing convertible top defect.
Full Vehicle Buyback
Easy Lemon successfully secured a full Vehicle Buyback from General Motors — the strongest possible outcome in a lemon law case. The manufacturer repurchased the defective Corvette and our client paid nothing out of pocket for legal representation.
