I had just gotten a safety inspection 15 days prior to this event to renew my registration. The car had been driving perfectly. Me and my wife had drove to my daughter’s school to pick her up. The school is about 10 minutes away from our home. Once we left the school we got about 3 minutes down the road and started smelling a strong electrical/plastic burning smell. Suddenly the car stalled and shut off. Then it cranked back up. Then it shut off. It did that several times. Smoke started pouring out from under the hood. I was barely able to get the car off the road and into a parking lot before it completely died and stopped cranking and stalling. I immediately got my family out of the car and had them run to safety. There was several other family’s with their children who had also just been picked up all around us. So I ran to car and popped the hood. There was so much electrical smoke coming out from driver side area. It appeared to be coming from the hybrid high voltage system under the ECM. I quickly disconnected the negative terminal on the 12v battery to shut down the electrical systems on the car. I have called Infiniti and I am dropping car off tomorrow to have a full inspection done to find out what happened. I am reaching out to you because I know that there is documented reports of this exact thing happening to other cars and that there was a recall R21B4 that they did a software update for. I believe that that update did not work to prevent this catastrophic event from happening. I don’t know if they will try to act like this was not related to the recall so I am trying to cover all my bases here by filing this complaint with y’all as well. I also have an open claim with Infiniti corporate. They are trying to just say that I no longer have a warranty for my car but this is a safety concern not just a warranty issue. I will be taking my car to Infiniti Clear Lake in Houston Texas tomorrow for them to look at it.

What component or system failed or malfunctioned, and is it available for inspection upon request? The rear AWD electronic coupler is failing. It is available for inspection. How was your safety or the safety of others put at risk? If it completely fails, the car can become inoperable while driving at any time. I was also told by the dealer that the differential could damage the transmission over time. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealer had diagnosed this issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning or messages. There is grinding when turning at low speeds and when driving sometimes there is a "bump" at around 40 mph. This was first diagnosed by the dealer in 2020 and again in 2022. There was a recall of the rear electronic coupler for the same year, make and model but, Infiniti says that it did not apply to my VIN. The TSB is 12-072C. My research of this issue shows that this issue common for my make, model and year. Clearly, this issue affects many more VINs than, originally recalled. The recall for this issue should be expanded to include my vehicle and extended so that this very expensive repair can be made without cost to me. I purchased this car because, I wanted a safe and reliable car to transport my small children. These critical issues jeopardize the health and safety of my family every day. My car is no longer safe or reliable. Additional, in 2020, at the time that the electronic coupler failure was diagnosed, something related to the CVT was replaced because of a recall. This year, I had to have the the transmission replaced. I now wonder if that could have been related to the CVT issue. My catalytic converters also had to be replaced this year.

The vehicle constantly shudders and almost stalls when in reverse or in low gear. The vehicle seems to not switch properly between the hybrid battery to the engine or vice-versa. The vehicle has a recall from October 2021 and Infiniti has not fixed the recall yet. I feel the vehicle is unsafe. I have emailed and contacted Infiniti to no avail. Infiniti has not remedied this recall in any fashion in almost a year.

I took it in for recall R21B4 to be reprogrammed and problem fixed. The problem still persist as I’m driving the vehicle loses all driving power which is dangerous while it has happened to me while driving on the express way. Infiniti is telling me i need to bring it back in to have my vehicle checked out and wants to charge me 186$ when the recall clearly states that the problem is the recall

I bought a 2014 INFINITI QX60 and after one week, my vehicle started to jerk after resuming from a stop sign or stop light but was just annoying at first. Later that day, the check engine light came on and I took it to auto zone to get the code which displayed "P1715 - Input Pulley Speed Signal" and secondary DTCs were P0776 (Pressure solenoid B performance/stuck off. When I am driving, I cannot make it a mile without having my RPMs skyrocket and my vehicle become inoperable and makes me turn my flashers on and find a place to pull over, shut off my vehicle, and restart it. This repeats over and over and over if I continue to get to the grocery store for essential needs but it is not safe to drive and will for sure cause a collision if it keeps happening. There are so many issues with this make/model and needs to be addressed for the safety of others on the road and myself/children as it is unexpected and very scary.

When taking off from a dead stop sometimes the vehicle pauses and moves very slowly enough to get you in the front of on coming vehicles, and then will not exceed over 10 to 12 MPH which takes up to 30 to 45 sec. Or more. I narrowly escaped a semi truck hitting me on the drivers side pulling out of our local post office. On several occasions I have needed to yank the vehicle off the road so as not to get rear ended in traffic. I have taken it to dealership several times, which they said they fixed the issue by replacing something called a break switch, "twice" this however did not correct problem. The national infiniti group sent a recording device which the dealer installed, this meant that when this event occurred I was supposed to reach down to the console where the device was located and push a button to record event all the while trying to avoid an accident. I successfully did it without incident and recorded the requested 6 events. This problem has been consistently occurring now for 7 months. I purchased this vehicle for my elderly parents with every available safety option for their safety, and I have not been able to let them drive the car for over 6 months since they took it on a trip. Fearing that they will not be able to react fast enough to avoid being in an accident or worse getting killed in this vehicle. I have been forced to drive it. Infiniti called today and said the results from data recorder showed no fix needed at this time, so they are clearly ignoring the issue as I have read online other people having the exact issue. Someone or some family is going to have a tragic accident with this problem and I want to go on record that infiniti corporate are fully aware of the problem and chose to do nothing.
