NHTSA Complaint #11719065 — 2020 INFINITI QX50

I am a [XXX] woman who purchased my first vehicle on December 6, 2024, with 43,000 miles. I have driven fewer than 20,000 miles since purchase, and the vehicle currently has approximately 62,000 miles. Until January 19, 2026, I experienced no issues. I have properly maintained the vehicle and followed all recommended service guidelines. I completed three oil changes during my ownership, averaging approximately every 8,500 miles. Two oil changes were performed by a licensed mechanic, and the most recent oil change and inspection were completed on November 29, 2025 at Legend Infiniti. I have receipts for all services. On January 19, 2026, while driving approximately 65 mph on a four-lane highway in Long Island, the vehicle suddenly went into limp mode and dropped to about 10 mph without warning. This created an extremely dangerous situation with a serious risk of collision. I first brought the vehicle to my mechanic, who advised me to take it to an authorized Infiniti dealership due to an engine bearing recall associated with my VIN. I brought it to the same Infiniti dealership that had serviced it two months earlier. After diagnosis, the dealership stated there was engine sludge and that I needed a new engine. They denied any connection to the recall and attributed the issue to poor maintenance. However, two months prior they completed an oil change and inspection with no documentation of sludge, engine concerns, or maintenance deficiencies. I was not informed of any recall at that time. My warranty claim was denied on the basis that sludge is not covered and that maintenance performed outside Infiniti could not be validated, despite providing receipts from licensed facilities. I am also being told there are record-access issues because the vehicle was originally sold in Canada. Given the sudden loss of power at highway speed and the known recall related to engine components, I believe this presents a significant safety concern and warrants investigation.
