2014 Infiniti QX60: engine overheating

Filed Mar 30, 2024 · Transmission · TX

While driving on my regular commute, the car sputtered when shifting gears automatically and stopped being able to accelerate beyond 30mph in the middle of a busy road. When the accelerator was pressed, the motor sounded like it was revving but not accelerating. An electric fire burn smell started to emit and a warning turned on for the first time reading “Hybrid System Overheated” as well as the check engine light. No issues before this incident. An independent third party service center confirmed that it’s an issue with the transmission. We confirmed that this is a common problem with other QX60s from 2014 that the transmission fails and replacing it does not guarantee that the problem will be fixed long term since the issue is that the original design of the transmission is flawed.

We get the message "Hybrid engine overheated" and after that loses power/acceleration causing vehicle to stall. This happened twice in last year. First time, we were at the Canadian border idling the vehicle when it happened. We took the car to our dealer for inspection and they said it related to a recall and updated the software. Few months later, it happened again in stop and go traffic and this time the dealer is saying hybrid CVT assembly has to be replaced at the cost of ~$15,000 including tax.

A few years ago, while in stop and start traffic on a hill, i experienced the hybrid engine and regular engine failure multiple times. Infiniti replaced my transmission. I have yet to recreate the same stop/start situation on a hill but have smelled the same smell of burning while in stop start traffic on a highway. Now infiniti has issues a recall for this very issue. I'm wondering what constitutes a "reasonable time" for infiniti to provide a solution as this is going on 6 months. I'm very concerned that my car is particularly vulnerable to this failure as it has occurred before. Yes, there was a warning that the hybrid system was overheating and then it died not much longer after the warning.

My wife purchased 2014 infiniti qx-60 SUV on january 23, 2014. She noticed when setting the intelligent cruise control at 40 MPH the vehicle will pick-up speed going downhill. Depending on the length and grade of the hill the vehicle will increase as much as 30+ MPH. When I drove the vehicle I noticed the engine RPM's remained at, 1500 RPM's, but the speed would continue to increase. On march 18,2014 I made a visit to dealership and met with the service consultant and the service manager. I explained what I experienced and asked if they could look into it for me. When I picked up the vehicle I was told they were unable to duplicate my concern. I then contacted infiniti consumer affairs via email and explained my concern. I received a phone call from the consumer affairs person, and was told to call the dealerships service manager to schedule a test drive of the same model. I found it to have the same problem as my wife's car. I call the consumer affairs person at infiniti and told him what I found. He explained that was how the cruise control was designed and is normal. On november 19,2014, I request to be notified when the infiniti representative would be at the dealership. The infiniti representative happen to be in the services managers office so I explained my problem to them. The service manager suggested we go for a test drive, and he drove. He set the intelligent cruise control at 40 MPH, when we started downhill the vehicle picking up speed. When we reached the bottom we continued to pick up speed, almost 30 MPH. The service manager contacted the infiniti technical support group and explain what he experienced, and was told that this is normal. Sections 5-53 - 5-56 in the owner's manual states under the warnings "on steep downhill roads the vehicle may go beyond the set vehicle speed and frequent braking may result in overheating the brakes".
