Infiniti QX60 fire or smoke problems

Filed Feb 22, 2026 · Electrical, Fuel system · TX

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.

The vehicle needs a completely new engine and I had made it known that I want to trade in the vehicle the very next day but was told that I need to wait until 30 days has past. I have reached out to the Loan institution and have documentation provided below of that INFINITI database in November of 2023 that this same vehicle needed a new engine. Both my children were hospitalized for breathing in these toxic vapors that were released from the tailpipe of the vehicle to which HGREG said they resolved and did not, as soon as vehicle started up the whole dealership came outside thinking someone's vehicle was on fire. Both my children are age 2 1/2 and 11 months old. Both were on breathing treatments due to the level of carbon monoxide released in vehicle while driving.

I was driving to work and then the vehicle stopped working once I reached a red light. It would not start and had a burning smell with smoke coming out. I had to call the police which they deemed undrivable and not safe. The car said battery but upon inspection it was a starter and possible belt problem. I've only had this car for less than three months and did an initial inspection where everything was deemed good. Now the car has not shown any problems and had an oil change for basic militance. I had no indications what so ever. It is currently being inspected by the dealer but I have heard back. I do know however, The towing company had tried to turn it back on and it was unsuccessful in both attempts. They had to forcefully tow the car which left tire marks.

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 the federal safety agency 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.

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.
