2019 Infiniti QX50 Engine

2019 Infiniti QX50 was purchased new 9/3/2018 Engine safety problems started 9/3/22 and it was fixed in a two days. Total engine failure diagnosed by Infiniti Cerritos on March 31, 2025. The car was at 103,900 miles at this time. At this time the warranty coverage was for 72,000 miles and not extended to 120,000 miles yet. I paid for the replacement of the engine on 9/5/2025. I later got a recall notice and it said that the warranty engine coverage had been extended to 120,000 miles and that I would get reimbursed for repairs. I never got reimbursed after I submitted a reimbursement claim form through Infiniti assist. I keep getting the run around at Infiniti Consumer Affairs. I submitted a Lemon Law claim and the arbitrator is showing a lot of bias and I keep getting the run around as well. No arbitration meeting has been scheduled. I now got a 2nd recall notice on January 29,2026 stating that the engine oil pan needs to be checked for metal debris and it’s possible that engine will need to be replaced if metal found. I scheduled an appointment on February 10th, 2026. At this appointment I also notified them that I still hear a noise in the engine. Infiniti Cerritos refused to do the recall. They also want to charge for inspection diagnosis of the engine noise when it should be covered under the warranty and recall notice. It says free of charge on recall notice. This car is obviously a lemon because if the engine gets replaced it’s bound and will continue to have the same type of safety issues.

I have called sewell infiniti multiple times for service appointment to check on my engine , per the recall notice. They said they were not taking appointments because no parts yet. And just wait for them to contact me. I have call them around October and December. Both times they said the same thing.

NHTSA has closed the case on Nissan WHY? Nissan / Infiniti issued recall notices over 2 months ago to bring my vehicle in to inspect the engine oil for metal shavings. I called a few Infiniti dealerships they all say the same thing. Inspection and replacement of engine is on hold. By NHTSA closing the case there is no government agency over seeing Nissan on solving this recall quickly. They did issue a 10 year or 100,000 mile warranty on the motor. I had my oil analysted by a company to give me a report on what metals on in my oil. The report came back with a unusual amount of silver metal 5 ppm. the report states that it's a concern normally average ppm is 2.with that problem the vehicle should not be driven. So I called Infiniti spoke with a service advisor about the report. He told me everything is at a stop with the recall nothing can be done. Wait for another recall notice in the mail. So now I have a vehicle that was recalled for the engine that is a safety issue and I'm unable to drive knowing about the metal in the oil. And the NHTSA closed the case on Nissan. Here we all sit waiting not knowing days, months or years before this will be resolved. How about a little help. Nissan and Infiniti should be paying for rental vehicles if we're unable to get our vehicle repaired. Nissan just issued a 10 year or 100,000 mile warranty and I can't use it for my engine right now today because the recall is on hold. What good is the warranty I see a problem can't get the vehicle looked at. Help is needed here.

Infiniti has admitted the KR20 VC-Turbo engine is defective and can catastrophically fail while driving, but they are dragging their feet on providing a remedy. By delaying the fix, they are gambling with customer safety — waiting until engines actually break to minimize repair costs. This is reckless and puts my family at risk. I am requesting immediate intervention by regulators to compel Infiniti to release the repair solution without delay, and to hold the manufacturer accountable for stalling tactics.

I went to Bill Dodge Infinity to test drive vehicles and to trade my Infinity QX50 in. KBB listed it as $38,000 as a trade in. I was told because of the “STOP TRADE” due to the engine recall they could only offer $12,500. Because of the recall. They couldn’t give me an idea if and or when it would be fixed. So I loose $25,500 in value on an payed off vehicle that I bought in good faith. What’s my recourse?

I was driving at the intersection of South I-55 and I-355 on the left most lane at 70 mph. All of a sudden, my car started knocking and since there was no shoulder to the left I had to move to the right by managing to get through multiple lanes to get to shoulder safely. Given the issue with engine, it would not accelerate so I had to safely decelerate and come to a stop. I called the towing company and they towed my car to the dealership. This car had a recall when the dealer contacted me and I had them take a look at 98K miles and they stated everything was fine. Following few weeks later, the engine completely gave out. The dealer is working with manufacturer to get the engine replaced. However, he is not sure who will pick up cost for replacing turbo. Turbo is part of the engine and should also be replaced under the recall. Needless to say, this was a dangerous situation and I am glad the situation had a safe outcome.
