ENGINE
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.

ENGINE
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?

SEATS
The driver side seat has felt loose and not secured for some time and rocking while driving. I am just learning that multiple Infiniti/Nissan models have had similar problem where seat mounts at rail/frame are coming loose and creating a potential safety issue. Previous attempts to have a retailer resolve were unsuccessful as they tried to charge me several thousand dollars for it. I plan to try again at different retailer when I take it in for NHTSA Recall 25V-437.

ENGINE
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.

STEERING
On August 1, 2025, at 44,391 miles on the Vehicle odometer, Plaintiff experienced a catastrophic failure of the complete power-steering and rack and pinion system, while traveling on Vermont Interstate 89 in Middlesex, Vermont. The steering wheel instantly became largely immoveable, the car shuddered and vibrated. By sheer luck, Plaintiff’s Vehicle did not collide with another vehicle or object. The Plaintiff could have been seriously injured or killed, had a collision resulted from the loss of steering ability. Plaintiff navigated to a nearby park and ride pull-off; the vehicle was completely incapacitated. An inspection of the Vehicle by Infiniti of Nashua Service Department revealed that the complete power steering rack and pinion system had failed. Service records research by Infiniti of Nashua Service Department revealed that at 31,000 miles on the Vehicle odometer, the power steering and rack and pinion system had a previous complete failure and was replaced under Warranty. The Service Department advised that failure of a system at 31,000 miles, let alone again at 44,391 miles, indicated a factory defect or an improper installation/repair of the system on the part of Infiniti. INFINITI OF WARWICK RHODE ISLAND DID NOT DISCLOSE THE COMPLETE SYSTEM FAILURE at the time of the 31,000-mile replacement, and falsely reported to CarFax “steering/suspension checked,” instead. Litigation pending.

UNKNOWN OR OTHER
The plastic clips on the panoramic sunroof holding the sunshade cover snapped while I was driving causing the shade to rapidly roll up. Note that there was no misuse of the sunroof shade and I wasn’t even using it when this Happened. This seems like a dangerous liability in case it were to hit the driver while on the road or distract them. After looking at my extended warranty I found my dealer does not cover the repair and I have to pay upward of 2k just for the plastic clips. There are no TBS for my vehicles vin on the sunroof rails breaking but there are for rattling and it even mentions issues with the clips but no problem to fix it. There are no lights to indicate this feature is broken on the dash as well.
