2015 Infiniti QX60 transmission problems

Filed Feb 1, 2026 · Engine, Fuel system · IL

Shortly after purchasing this used vehicle from CarMax, the vehicle began experiencing serious mechanical failures involving the engine/emissions system, braking system, and suspension. The vehicle displayed a check engine warning light, and the selling dealer, CarMax Schaumburg, confirmed issues requiring repair, including a faulty oxygen sensor, brake-related repairs, and a suspension link. The vehicle was taken in for service, parts were ordered, and repairs were performed. Despite these repairs, the same issues reoccurred, requiring the vehicle to be returned for additional repair attempts. The problems were therefore reproduced after the initial repair, confirming the existence of unresolved defects. The vehicle was not reliably safe during this period. These failures posed safety risks due to reduced braking reliability, compromised vehicle stability, and engine performance concerns, which could affect drivability and safe operation under normal conditions. The defects were confirmed and serviced by the dealer, as documented through service communications and voicemail messages from CarMax. Warning indicators, including the check engine light, were present prior to repair and prompted service visits. Exact mileage at the time of the incidents is UNKNOWN, as it was not clearly disclosed at purchase. Before the issues were fully and permanently resolved, the vehicle was repossessed, resulting in the loss of the vehicle while unresolved safety and mechanical defects existed. The repossession prevented further inspection or repair by the consumer. The repaired components and service records should be available for inspection through the dealer. No police or insurance inspection occurred in connection with a collision, as the issue involved mechanical and safety defects rather than an accident.

In the beginning when I pull off the car shudders and jerks speed was delayed. Now in the middle of driving with some speed the car beginnings to strain and barely move although the gauge shows I’m going 40 miles the car is straining and going under 5 miles. This started maybe a year ago but now it is much worser.

Transmission has a shudder between 15-20 MPH around 1000-1500 RPM. Mainly happens in STD mode, other modes run at higher RPMs but does still happen on occasion.

Vehicle looses power randomly. No engine or warning lights. RPMs will rev but car will not go into gear or drive. I can shut off the vehicle for a couple hours then restart and will drive fine until randomly happens again.

Hello the CVT transmission in these 2014-2017 vehicles have been known to be defective. Apparently Infiniti settled a lawsuit that was suing them for this exact reason. They settled without admitting fault. Problem with that is all these vehicles are still on the road and customers are unaware. They say they informed us but I can assure you I never was informed. They also sent a service bulletin to their dealerships telling them to expect problems and to fix if brought in. The vehicles are dangerous without a doubt. They shake, shudder and lose acceleration with no warning. No lights come on the dash or anything. Someone will lose their life, if they haven’t already. The law firm had company emails showing they were going to do a recall. Corporate greed is my guess, got in the way. Now unsuspecting customers are driving ticking time bombs. Also owners are trying to sell these vehicles to unsuspecting customers. There is no way this should be acceptable in my opinion and am extremely disappointed with the lack of concern I’ve received from the company. We are paying for a so called “luxury” vehicle only to find out later that the transmission should of been recalled years ago. Here I sit with my 20k used vehicle blue book broken down car now. It’ll cost $9800 to fix. Just isn’t right and I hope I’m finding someone that will at minimum look into it. Please, do us all a favor before it’s to late. Thank you.
