Description of the problem | On a recent trip to san antonio, tx hill country on a very hot day, the hybrid system over-heated on a slow speed climb to a steep hill. Engine and transmission shutter and stopped powering the wheels. The vehicle start to roll back on to cars coming behind. I had to press emergency brake and shut off the engine for 10 minutes. On start the hybrid warning sign was still on. However the powerr to wheel were back with car still shuttering. From then onwards had to start and stop the engine until reaching the top of the hill. On reaching top, had to stop and park the car for 2 hrs. Start the car again, still the hybrid warning sign on. Then drove down the hill avoiding any more up hills a into costco parking and left the car parked for 3 hrs. After that, start the car and the hybrid warning sign went off. Drove back to houston and showed to the dealer and the computer diagnostic code shows hybrid motor inverter controller failed. Also notice the part of third row seat burnt where the hybrid battery is stored. However the dealer mentions they battery is fine. Now we are scared to drive this car on very hot days to any steep hill. Failure of power to wheels was pretty scary. With brunt mark on the third row seat makes this car even more scarier since this car is only used by my wife and kids. Thinking of anything happening to them because of fire or power failure makes this car really unreliable. Another issue that happens very winter is loud knocking during extreme cold (32 below) days. We live in sugar land (houston) tx. Very seldom we get very cold days. However whenever we do, there is extremely loud knocking sound coming from the front passenger side of the engine compartment. As per dealer this is normal with infiniti qx60 hybrid. I spent close to $67k for this car. I have been extremely disappointed with performance of this car. |
