POWER TRAIN,ENGINE02/19/2026
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.

VEHICLE : IMNFINITI QX50 YEAR: 2020 LOCATION : PUERTO RICO My Infiniti QX50 has an active engine recall by VIN In 2023 the Infiniti dealer in San Juan PR documented oil sludge in the engine and performed and engine flush and internal treatment . The vehicle was returned to service and was not declare unsafe In 2024 , the same Infiniti dealer performed maintenance and again returned the vehicle to service without restriction The vehicle has now develop internal engine damage . The dealer is denying recall coverage , stating the damage is due to oil sludge and alleged lack of maintenance . The denial is inconsistent with service history , as the sludge was documented and treated while the vehicle was under dealer maintenance , and dealer performed maintenance continued after that finding. Additionally , Infiniti Consumer Affair stated they cannot assist because the vehicle is in Puerto Rico. I am concerned about federal safety recall. not being honored in US territory , and about vehicle being unsafe to operate due to engine failure risk I am requesting NHTSA review and assistance to ensure recall compliance

Crest Infiniti staff, including Service Rep Trevor and Manager Randy Nadors, misrepresented Recall 25V437 as "not a safety recall" and claimed repairs were stopped until year-end. This contradicts NHTSA"s designation of 25V437 as a serious safety recall and Infiniti Corporate's confirmation. Their false statements indicate a failure to disclose material safety information and unsatisfactory service, thereby putting consumers at risk.

My vehicle is affected by Recall 25V437. I am already experiencing recall-related symptoms, including stuttering, unusual engine noises, and uneven acceleration. I leased the vehicle through DFW Auto and Services INC, On August 15, 2025, at 9:35 AM, I spoke with Sam in the finance department of DFW Auto and Services INC during a 3‑minute call from 214‑205‑7327. I specifically asked about the recall affecting this vehicle. Sam stated that the recall had been “taken care of.” This was false, as Recall 25V437 remains open and unresolved. The dealership misrepresented the recall status of my vehicle, failed to disclose that Recall 25V437 remained open, and delivered a defective product – a vehicle with a known safety defect that directly impacts usability, value, and consumer safety. On November 18, 2025, I submitted a formal complaint to the Attorney General regarding this matter. This misrepresentation placed me at risk of driving a vehicle with a known safety defect that could result in sudden engine failure or fire. I am requesting NHTSA to investigate the dealer’s misrepresentation and ensure proper enforcement of Recall 25V437. This recall must be remedied at no cost to me. I have contacted: Crest Infiniti 6100 State Highway 121, Frisco, TX 75034 to have Recall 25V437 remedied. I am currently still waiting response from the service center for an appointment to have the engine replaced.
