Q60

  • Automatic transmission
  • 64,124 miles

Just found out the engine needs to be replaced.

Only 64,400 miles.

Did normal maintenance.

replaced brake system twice...

They said over $16,000. for new engine. Really disappointed. I suspect there is a defect, for this, many reported problems of sludge. Imagine the number of people who have NOT reported it.

suggestions welcomed.

Q60

  • Automatic transmission
  • 39,500 miles

Engine in a 2017 QX60 overheated causing OIL to sludge. The engine malfunctioned and INFINITI will not honor the warranty with only 39,000 miles. All maintenance records up to date.

What others wrote was what we experienced with our 2017 Infiniti QX60 also. My Infiniti has 23,000 miles and we're 2 1/2 years into our lease. There was white smoke coming out of the exhaust in the morning and then the engine seized without any warning lights prior. When the dealership looked at the vehicle, they said that the engine had sludge and therefore this would not be covered under the warranty due to our neglect. We also had proof that we had done regular oil changes and submitted receipts to corporate. We did not do these oil changes at the dealership so the manufacturer first questioned the validity of my receipts and then came up with all sorts of objections saying that there was no way to confirm what type of oil was used (even though the type of oil is clearly indicated on the receipt), or the viscosity of the oil used, or if we added more oil later that was the wrong type.

The manufacturer denied the warranty claim and said that it would cost $14,000 to replace the long block assembly. I can't believe that a vehicle that is 2 1/2 years old with only 23,000 miles and having regular oil changes would have this kind of problem. And if a problem existed, why didn't the engine lights come on to notify me of a problem? I contacted the Better Business Bureau and had an arbitrator hear my case. This process has now dragged out for over 2 months and I still don't have a decision and have been without a car for 2 months and still paying my lease payments.

The arbitrator requested that a "technical expert" look at the car (which they pay for). This so called expert opened the hood of my car and 10 minutes later wrote a report saying, "Yep, there is sludge." What kind of expert is that? I want to know what caused this sludge when I've had the required maintenance done. There must be some sort of inherent engine problem or a problem somewhere else that would cause this type of sludge.

It's nice to hear that other people have also experienced this same problem, but what I'd love to know if you were able to get any resolution from the manufacturer and if there are other people out there with the same situation.

A KNOWN ISSUE WITH THE CAR AND THEY JUST DENY THE WARRANTY.
