ENGINE, UNKNOWN OR OTHER
Car recently had an important safety recall that was suspended, my car is a 2019 QX 50 Infiniti Luxe, that recently shut down and had to be towed, infiniti dealership diagnosed the car and says I have all low compressions and that I need an engine, these symptoms were quoted to my service dealership prior that the car hesitate to take off, low pick up when I accelerate, stops out of nowhere at intersections, I was told car performs as it was designed to perform even tho I explained it has like a growling sound, now here I am with an engine failed vehicle that they are trying to charge me 13,000 for repairs, I am still paying on this car and have a balance of 14,000+ owed, the dealership is saying they performed a recall diagnosis and that no debri was found in oil pan, any mechanic should know just because debri wasn’t found in the oil pan does not mean the car is not eligible for recall repairs, especially if the diagnostic test was done too soon, the car is definitely part of the recall but they will not honor that, I only had the car just 3 years as of September 2025, the car itself is only 6 years old, this engine failure is definitely part of the recall and I should not be responsible for this repair, this is a safety hazard for me and Infiniti should be held accountable for this faulty engine.

2019 Infiniti QX50 Recall Campaign ID: R25B2 (Safety Recall 2025) Summary of Issue: I received a safety recall notice stating that my vehicle may have an engine manufacturing defect that could cause severe damage or complete engine failure. This poses a significant safety risk. Details: Contacted Infiniti Consumer Affairs on August 28, 2025 (Case #55702324) and my local dealer. Dealer confirmed recall is active but remedy is not available; they refused inspection even if I offered to pay. Consumer Affairs indicated proactive assessment may incur charges unless defect is confirmed, which I find unreasonable given the severity of the issue. No timeline provided for remedy or inspection. No alternative transportation offered. Safety Concern: Driving the vehicle under these conditions could lead to sudden engine failure, increasing risk of accidents and injury. Requested Action: Confirm recall status and remedy timeline. Require manufacturer to provide inspection or alternative transportation until repairs are available.

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.

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?
