general problems of the 2018 Infiniti QX60

The contact owns a 2018 inifiniti Qx60. The stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed with a failed timing chain. The contact was informed that the timing chain needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The contact referenced an unknown recall which had a similar failure description, however the contact's VIN was not associated with the unknown recall. The failure mileage was approximately 65,000.

The rear differential is messed up on this truck, and there is grinding noise - when I turn left or right, and there,s a whinning noise while driving, and also black fluid drips from in between the oil pan, and transmission and hissing sound when turned on. .

Check engine light came on, poor idling and start up. Infiniti replaced pvc hose that was cracked, electical seat warmer issue was fixed, dvd electrical issue was denied under the claim warranty, and some sensors were replaced due to codes of lean fuel, and the technician noticed a ticking noise. The dealership told us to pick the car up, drive it and put more miles on it and bring it back in to file another claim for the ticking sound. Returned to file new claim and was told the engine needed to be replaced or timing chain should be replaced due to sludge in the engine even with proper maintenance [records submitted to dealership for warranty claim which was denied]. Passanger seat warmer had also gone out since our last visit, so they're fixing that electrical issue as well. [we were denied for driver side electical window repairs, as they said components were "only loose"]. We purchased the elite protection plan that should have covered all issues but they are denying the claim. Main concern is the engine as there are multiple forums and social media groups that are complaining of the engine sludge issue on new or certified Infiniti or Nissan vehicles with the same engines. Most owners are providing service/maintenance records and still being denied engine repair or replacement under warranty. These engines need to be recalled and consumers need to be compensated for their time and repairs.

The contact owns a 2018 Infiniti Qx60. The contact stated that upon attempting to start the vehicle, he heard an abnormal sound coming from the engine compartment. The vehicle failed to start. After calling roadside assistance, all attempts to jumpstart the vehicle failed. The check engine warning light was illuminated on the instrument panel. The vehicle was not taken to a dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 154,000.

Since my car had about 45000 miles on the odometer, it has been producing a thick white smoke, not only upon starting the car from a cold start, but also after longer distance trips over 30 miles. After having taken it to the dealership multiple times, their response has been that they cannot recreate the problem and most likely it is from engine sludge due to not maintaining the regular oil change schedule. After having shown the dealership the timely maintanence schedule I had performed on the car over the years, they continued to claim that there is no problem with the car. After the standard warranty had run out one year later and upon taking it to the dealership they claim that I need to replace the head gasket and it would cost me $3500. In addition to the avoidance game they played over that year, in my opinion they were simply pushing back the maintenance until the warranty ran out. This is a common problem with this specific car and the low mileage and I know of at least one more family experiencing this problem. There needs to be a thorough investigation on not only the problem with the engine of this car, but the potential of unscrupulous business practices of the dealerships.

I purchased my 2018 Qx60 in 2021 at competition Infiniti as a certified pre-own vehicle. I soon began to hear a rattling noise and the steering wheel would vibrate a little. I brought the vehicle back to the dealer several times with this complain and they keep telling me that their is nothing that the can do for me because that’s the way the vehicle is built. The noise as I was told is common in Qx60 models and that I’m not the only person that has complained about it. I told him that I don’t expect for a $30,000+ luxury vehicle to sound that. They also explained to me that it was something that was built in the vehicle to help with fuel efficiency. I think he called it a droner or something like that. I love the look my vehicle but I hate driving my vehicle because of this noise. I filed a complaint with Infiniti consumer service as well, who instruct me to have the fail inspected by another Infiniti dealer to make sure the dealer is not refusing to fix the problem. I am disgusted that a vehicle that I purchased at an Infiniti dealer is sounding like this. If you can provide any help in this matter, it would be greatly appreciated.
