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.

ENGINE
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.
