2014 Infiniti QX60 Powertrain & Transmission Problems

My vehicle is having issues with the CVT transmission timing chain, I was just aware, there was a recall in the past but my infiniti dealership said it's expired.And they won't help replace it. I'm getting Judder while driving.

The contact owns a 2014 Infiniti QX60. The contact stated that while driving 25-30 MPH, the vehicle shuddered and failed to accelerate as intended upon depressing the accelerator pedal. Additionally, the contact stated that upon shifting into reverse(R) and depressing the accelerator pedal, the vehicle failed to reverse and drove forward instead. The manufacturer was notified of the failure, and a case was opened. The manufacturer informed the contact that the VIN was included in Infiniti Campaign Number: PC501. The manufacturer scheduled an appointment with the dealer on the contact's behalf. The vehicle was towed to the dealer, and the dealer informed the contact that the TCM software was updated; however, the failure persisted. The Service Advisor at the dealer informed the contact that the transmission needed to be replaced. The regional manager was contacted and informed the contact that the dealer had stated that the service campaign had not been performed, and the vehicle had not been diagnosed. The contact was informed that no assistance would be provided. The vehicle was not repaired. The failure mileage was approximately 122,000.

I am reporting a serious safety failure involving my 2014 Infiniti QX60 Hybrid (VIN: [XXX] ), tied to Recall R21B4 / NHTSA 21V-774. Although the recall was marked complete before I bought the car in 2022, the defect — sudden loss of power — occurred again while I was driving at highway speeds. Infiniti is refusing to assist due to age/mileage, despite clear evidence the recall fix was ineffective or incomplete. Diagnostic codes confirm hybrid system failure (P0A08, C1A1A, C1130). I am requesting a full investigation into Infiniti’s handling of this recall and a resolution for my unsafe vehicle.

This vehicle started shaking and juttering at a lower speed and made it very difficult to drive. Then I could accelerate and it would not go faster. I took it to a repair shop and they were getting CVT codes for the transmission. I looked online a found that many other people had these same issues as well as a Class Action Lawsuit that was settled a few years ago for 278 million for these problems. I was never informed that this CVT was a problem and could have it replaced from Nissan for no charge. I am not sure why Nissan would allow an unsafe transmission to be installed into a vehicle that would make the car unsafe to drive.

The car is not engaging when going from 1st to all gears, the car feels very shaky and unstable

The whole vehicle experiences strong vibrations when accelerating to 30 miles per hour and higher. It also gives strong judder or kicks when turning. Hard to control the vehicle at high speeds. No warning light is on. Took the vehicle to a local dealer (Houston Southwest Infiniti) and found that the problem was caused by a defective rear differential coupler.

When the vehicle slows from cruising speed to below 20 mph, the car shakes violently and the engine nearly stops. To avoid the shaking, I must place the vehicle in neutral until it comes to a complete stop. If I shift into drive before I stop, the vehicle shudders again. When in traffic, it could cause the vehicle to be rear-ended. My wife won't drive the vehicle because of this. Owners' Forum seems to indicate this is a common problem and may be related to [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I bought my 2014 Infiniti QX60 in 2016 that had a little over 68k miles on it. On May 3, 2024, I just hit over $100k & felt the car do a soft lurch then it started to do a small crawl inch by inch. No warning lights came on or messages. Before this happened, I heard what I thought was a flat tire, or a plane taxing sound. I got the car towed to a mechanic shop and was told that I need a new 'transfer case'. I was told that there was a recall for this but do not see it for this model. If Infiniti knew it had problems why was a recall not done. If I want to get it fixed it will cost over $5k again. I already got it changed and the front differential a year ago. So is this something that will have to be done yearly?

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.

Transmission is making a whining noise when accelerating. Also studders/jerks when trying to shift.

The contact owns a 2014 Infiniti QX60. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact drove the vehicle to a nearby parking lot and parked the vehicle. The vehicle was turned off and restarted; however, the gear shifter failed to shift into drive or reverse. The vehicle was towed to the dealer where the contact was informed that the installed alternator was not OEM and not sufficient for retaining power to run the vehicle. The contact was informed that the alternator needed to be replaced. The vehicle was not repaired. The vehicle was towed back to the residence. The contact stated that the latest failure began in January 2024. However, the vehicle had been towed several times to the independent mechanic and the dealer since the failure first started. The contact stated that the alternator was replaced in March 2024 with an aftermarket alternator; however, the failure reoccurred. Additionally, there were several unknown warning lights illuminated since replacing the alternator. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 85,614.

The vehicle lost power while driving , that resulted in stop during active trafic and the car towed.

The car begins to shake and shutter when I reach 2500rpms

The contact owns a 2014 Infiniti QX60. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power and failed to accelerate as intended. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the transfer case. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA hotline for assistance. The failure mileage was 160,000.

TRANSMISSION SHUDDERS, 140,000 MILES, CAR WILL NOT MOVE FORWARD OR BACKWARDS, TRANSMISSION REPLACEMENT QUOTE IS $6K TO $9K

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.

Consistent CVT shudder while accelerating from a "stop" through 25-30 MPH, and also sometimes while accelerating after moving and lasting through 40 plus MPH. This transmission shudder necessitates releasing the accelerator pedal, slowing down, sometimes selecting a different driving mode (i.e., SPORT, ECON, etc,). This has caused difficulty joining the traffic stream, especially at highway "on ramps" and when we have to accelerate quickly to join traffic even during "in town" driving. This initially started last summer and was inconsistent (about 110,000 miles on the vehicle). The last week it has happened repeatedly. According to my research, it is a very common safety problem with this vehicle.

WHILE DRIVING, ENGINE SUDDENLY STARTED SHAKING/JUDDERING. THEN WITHIN JUST FEW SECONDS, ENGINE WENT INTO EXTREME HIGH RPM ALONG WITH STRONG SMELL OF SMOKE COMING OUT OF VENT AND CAR STOPPED MOVING COMPLETELY AND ENGINE TURNED OFF BY ITSELF. WE COULD TURN ON IGNITION POWER AND ENGINE START, BUT TURNED OFF AS SOON AS PUT ON DRIVING OR REVERSE MODE. HAD TO TOWED IN TO LOCAL NISSAN DEALERSHIP WHO RAN DIAGNOSTIC TEST WHICH REVEALED CVT CODE P2857 AND WAS TOLD THAT TRANSMISSION NEED TO REPLACED. NOTICED SEVERAL CONSUMER COMPLAINTS OVER NHTSA WEBSITE REGARDING DAMAGE TO TRANSMISSION REQUIRING REPLACEMENT IN 2014 INFINITI QX60 HYBRID VEHICLES AND NO SAFETY RECALLS/REPAIRS OFFERED BY INFINITI/NISSAN MANUFACTURE REGARDING SUCH MAJOR AND DANGEROUS POWERTRAIN/TRANSMISSION BREAKDOWN.

The contact owns a 2014 Infiniti QX60. The contact stated that while driving at an undisclosed speed, an unknown warning light illuminated, and the vehicle shuddered. The vehicle was taken to an independent mechanic, who cleared the fault code and informed the contact about Technical Service Bulletin: ITB12-072d (Vibration and/or Noise When Making Low Speed Turns). The vehicle was taken to the dealer, who informed the contact that the vehicle was out of warranty. The manufacturer was not made aware of the failure. The failure mileage was approximately 94,000.

I was driving the Infiniti QX60 and it started smoking and shuddering several times. I had to pull it over and have it towed. I've already had to replace the entire transmission and the transfer 4x4 case and both were brand new. This is nerve wracking and unfair. Something needs to be done. It's being diagnosed but this seems to be constant with this 2014 Infiniti QX60 model. This car needs to be completed pulled and replaced for every dryer for everyone who has one.
