Pattern Summary
- Repeated reports that the backup camera display intermittently went black or showed guide lines without a normal image.
- Multiple visits document that concerns were intermittent and difficult to duplicate during dealer testing.
- Records also reflect intermittent electrical/drivability complaints (warning lights and reported loss-of-power episodes).
- Additional warranty visits reflect sunroof malfunction/wind-noise concerns and related repairs.
- The overall record reflects a multi-visit warranty history for issues affecting use and day-to-day confidence in the vehicle.
Settlement Outcome
Without admitting liability or wrongdoing, the manufacturer completed a California Lemon Law repurchase (buyback) and paid the owner $84,390.75 as a monetary settlement. In a repurchase, the manufacturer buys back the vehicle and resolves the dispute under California’s Lemon Law framework.
California Lemon Law & Auto Fraud Rights
Based on the service-record pattern, this matter fits within a California Lemon Law framework: repeated warranty repair attempts for issues that the owner contended affected the vehicle’s use, value, or safety. California’s Lemon Law protections apply statewide.
For a document-based review, we typically look for:
- Whether the same defect returned after multiple repair attempts
- Whether the defect impacts drivability, safety, or core functionality
- Whether the paperwork consistently documents the complaint, diagnosis, and work performed
- Whether warranty coverage and repair opportunities were reasonable under the circumstances

California Lemon Law – Common Questions
How many repair visits does it take to qualify in California?
There is no single magic number. Repeated repair attempts for the same problem—or a defect that substantially affects use, value, or safety—can support a Lemon Law claim.
What if the dealer says they “couldn’t duplicate” the issue?
Intermittent problems are common in real-world driving. If your repair orders consistently document the complaint and the issue keeps returning, those records can still be meaningful.
Does my city matter (for example, Chino)?
No. California Lemon Law protections apply statewide. Chino is simply the location tied to this example, not a limitation on where a claim can be brought.
What documents should I gather for a case review?
Bring your repair orders/invoices (all pages), any warranty paperwork, and any settlement or repurchase paperwork if the case has already resolved.
Next Steps
If your Mercedes-Benz keeps returning to the dealer for the same issue—or core features like camera/infotainment are unreliable—get a focused document review. Deadlines can apply under California law, and early review helps preserve options.
