2014 Infiniti QX60 Hybrid power train problems

“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.”

“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.”

“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.”

“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…”

“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]”

“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?”
