Consumer Description

I purchased this 2021 QX50 Infiniti on [XXX] and have experienced consistent engine knocking. In checking out this problem, I have found that it is apparently a widespread problem with the engine in 2021 QX50 vehicles and can possibly lead to engine lock up and engine failure. The engine thus far has not locked up or failed. I have reported the issue to the dealership, Infiniti of Gwinnett located at 3090 Satellite Blvd, Duluth, GA 30096 and am scheduling to have the dealership investigate the problem. Needless to say this is a major concern and if there are ongoing NHTSA investigations and findings I definitely want to be made aware of same. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
