2020 INFINITI QX50 Problems

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.

The vehicle's engine light turned on. The engine light remains on, and frequently the Malfunction and System fault See Owners Manual will display. When the malfunction message appears all the traction lights are also turned on. The RPM's in the vehicle are very accelerated, and it's difficult to drive the vehicle. The vehicle will also produce a very heavy smog smell. I took the vehicle into the retailer several times and nothing was done. The manufacturer is also not taking responsibility and stated the issue is unrelated to the engine bearing recall.

Jan 25,2021 Highway 35 San Antonio Texas Display board lights turned off for a few seconds it made a click sound and the car turned off and turned back on for a few seconds, stalling the car. The automatic break was activated and deactivated at the same time. Trying to stop the car. This is the third time since octubre 2021 that this happens. My safety and the safety of the other drives was at risk, I can’t drive this car anymore because it may cause an accident. Approximate a month ago the car stoped in the middle of Stone Oak street in San Antonio Texas. I put the car in reverse and the car started working again. I took the car to the agency I was without a car for Several days because the agency doesn’t have a car available for rent. They could not find the problem of the computer glitch. Please the maintenance records for more details.

Infiniti has acknowledged that certain vehicles equipped with this engine may experience bearing failures caused by a manufacturing defect affecting the main, A-, C-, and L-link bearings. These defects can result in engine damage or complete engine failure, as outlined in Infiniti’s recall notice. In September 2025, I took my vehicle to an authorized Infiniti service center after receiving notice of the recall. At that time, I was informed that no repair remedy was yet available. I continued operating the vehicle as advised, and no warning lights or performance issues were present. However, on October 16, 2025, the Service Engine Light illuminated unexpectedly. I immediately brought the vehicle to the nearest certified repair facility the following day (October 17, 2025). Diagnostic testing determined that the engine had suffered internal bearing failure, consistent with the known recall condition. The vehicle required a complete engine replacement, which I had to proceed with at significant personal expense, covering both parts and labor. At no time prior to this incident did my vehicle display any warning indicators or abnormal performance. The sudden nature of the engine failure created a serious safety concern and considerable financial hardship. I am therefore formally requesting reimbursement or assistance with the full cost of the engine replacement and associated labor. I have attached supporting documentation, including repair invoices, diagnostic reports, and proof of payment, for your review. Given that the failure directly relates to the known defect identified in the recall, I believe reimbursement is both appropriate and warranted.

I was going 70 miles an hour on a highway with no cars around me. When the car suddenly breaks and beeped. It was very dangerous. I was in the center lane of a 3 Lane Highway with no one around.

While driving vehicle, randomly vehicle brakes are applied on their own, causing vehicle to suddenly slow down in traffic. Red warning light appears on the dash. This has occurred 6-7 times over the past 2 years. 3 of the times occurred on the interstate, causing vehicle to drop speed from 60-40 within few seconds. The other 3-4 times have occurred while driving underneath a light rail walk way and an underpass. Most recent incident was 12/25/21 on interstate. I am concerned this will contribute to a car crashing into the rear of my car. I had vehicle checked by my dealer today 1/7/22, and they were unable to duplicate the issue. They have submitted a report to Infiniti. I was unable to upload the documentation from Mike Ward Infiniti
