ENGINE
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)

ENGINE, FUEL/PROPULSION SYSTEM
We’ve taken the vehicle to two different Infiniti dealerships (Sewell and Crest) multiple times due to engine rattling, vibration noises, and propulsion issues. Unfortunately, we haven’t received any resolution or fix for these problems. We tried to upload a video with sound as reference but the platform doesn’t allow us to. We experienced similar issue that resulted in total engine failure on the highway with our children in the car in our Yukon Denali. We are fearful that something similar will occur. Please Help!!!

ENGINE
I have received email from my car dealer Grubbs Infiniti in Grapevine, TX. The email was regarding a recall for potential engine issues. I called my dealer and scheduled an inspection. When I sent my vehicle for inspection the dealer replaced my engine with a new engine without my consent. After the engine replacement I’ve received my vehicle back and I’ve been having issues where my vehicle suddenly got jammed while I was driving in my community. I called my dealer again and they took the car, fixed it and sent it back. Now after receiving the car my car is not starting and I did a jump start, eventually my car got started but I got an emission control system malfunction error and my car is not starting anymore. With all this I lost the confidence on my car and I need some kind of justice here. Thank you!!

POWER TRAIN, ENGINE
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.

Bluetooth and CarPlay connection suddenly disconnects from my iPhone while driving, usually after 5-10 minutes after establishing a normal connection. This only affects the use of the phone component and not the other elements of the connect (map/navigation, music are not affected). This is dangerous because I am often on a freeway and engaged in a business call, and I must rapidly either switch to using my handset or change to “speaker” mode on the phone in mid-call while driving. This has happened every time I have used this vehicle over the past two years, and I have taken it to the dealer (which is an excellent dealer (Sewell) that has an otherwise perfect service record. I am convinced Sewell has done nothing wrong. This has also happened on several other Infiniti models with my prior iPhones (different models with earlier versions of OS). I have been told in years past by Infiniti service corporate representatives in the past that there is an incompatibility between Infiniti and Apple phones. I was always told that the problem was solved on the next model vehicle.

SEATS
I purchase my vehicle [XXX], While driving it I noticed that my driver seat was moving when I drive and turn corner, go on a hwy on ramp, or turn in a driveway. The car is under the manufacturer warranty and I have been taking my car back and forth to the only Infiniti dealership here in Las Vegas. Every time I take it there they tell me they cannot duplicate it, but they have replaced my seat track 3 times, which 2 of what I was told was broken. I keep telling Infiniti that this is a safety issue for me and I don’t feel safe driving my car. They cannot tell me why the seat track keeps breaking and I don’t know what else to do. I took it the the dealership I bought the vehicle from and 2 people there were able to duplicate the problem with my seat.

UNKNOWN OR OTHER
There is rattling noise in the dashboard area that is evident when driving 55+ mph. The noise started in the middle of the dashboard. I took it in for service and was told it was a known air bag issue. After servicing the issue has recurred but has moved to the driver side dashboard area. If this is a known issue, I'd like to know to ensure the vehicle is safe to drive and that the airbag won't deploy while I'm driving. My car has been at the dealership in the service department for 9 days now. No update has been provided; which in itself is alarming.
