NHTSA lists 1 safety recall and 4 owner complaints for the 2023 Infiniti QX55. Most complaints involve engine (2) and power train (1). The EPA rates it 25 mpg combined.
Nissan North America, Inc. (Nissan) is recalling certain 2023 INFINITI QX55 and 2022 INFINITI QX50 vehicles. The incorrect door latch may have been installed in the front right-side passenger door lock assembly, preventing the front right-side door lock from automatically locking.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Complete sudden engine failure , motor lost acceleration. It started with engine knocking then full and complete engine failure. Oil light illuminated when engine failed. I did check the engine and oil was full on a cold engine and the vehicle is properly maintained as it is a leased infiniti vehicle. Please note there have been two previous engine light incidents. First I was told it was a speaker in the rear door, second I was informed it was an evaporation seal. Lastly was this very intense engine shut down. I have research and found that there are issues with the turbo bearing with my particular engine and turbo. Engine 2.OL 4 cylinder ( KR20DDET)”
“Every single one of these 2.0 litre engines should be recalled. My partner has a 2022 QX50 and the long engine should be replaced. On May 18, 2025, my QX55 with 16,500 miles that I was absolutely perfect in servicing suddenly started losing power, grinding, then the oil light came on, followed by the check engine light. Suddenly, it was undrivable in traffic. I was stuck in front of entrance to a hospital in the most inconvenient and dangerous place. It wouldn't start, and when it did, the grinding noise was incredibly loud. I was stranded and it was flatbed towed to Fort Wayne (Indiana) Infiniti, and the following diagnosis was yielded: CONNECTING ROD BEARING FAILURE FROM CYLINDER 4 - CONTAMINATED OIL CONTROL SYSTEM. INTERNAL FAILURE OF CONNECTING ROD BEARING. TURBOCHARGER OIL FEED LINE HAS METAL PIECES IN TURBOCHARGER. REPLACEMENT OF LONG ENGINE AND TURBOCHARGER ASSEMBLY REQUIRED. Nissan is trying to get away with recalling just a few of these. It is a design flaw; not an issue with a specific production period.”
“Rear seat heater malfunction causing the rear seat to overheat and stain seat cushions burned the seats as a total loss threat and concern on fire hazard manufacturer refuses to repair damaged seat under warranty coverage Infiniti consumer affairs case number 48556761 I have filed complaint”
