There are 1 owner-reported powertrain & transmission complaints for the 2023 Infiniti QX55in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
