While driving my 2020 Maserati Ghibli on a busy street, the engine suddenly seized without warning. The vehicle abruptly lost power, and I had to maneuver to the side of the road while traffic was flowing around me. Fortunately, I was able to avoid a collision, but the situation posed a serious risk to my safety and that of other drivers nearby. Component/System Involved: The engine is the primary component that failed. It completely seized and rendered the vehicle inoperable. The engine remains available for inspection upon request. This failure occurred on a heavily trafficked street, which made the sudden loss of power particularly hazardous. Had I been on the highway or in faster-moving traffic, the outcome could have been far worse. I was unable to maintain speed or control acceleration, placing myself and others in danger. The problem was confirmed by a certified Maserati dealership. Their service team diagnosed the issue as a complete engine seizure and confirmed that the engine would need replacement. There were no warning lamps, dashboard messages, or unusual engine behavior prior to the failure. The engine failed suddenly and without any observable symptoms. Manufacturer Response: Maserati has declined to offer any assistance or compensation for the failure, citing the vehicle’s warranty status. However, based on my experience and reports from other owners of similar issues, I believe this points to a larger reliability or manufacturing issue that should be formally investigated. They instead offered me to perform certain diagnostics to make a final determination if they are going to offer any assistance. They are asking me to pay $2400 for the diagnostics which I think it’s unreasonable. I respectfully request that NHTSA investigate this matter and evaluate whether similar engine seizures in Maserati vehicles are part of a broader safety defect.
