NHTSA Complaint #11509313 — 2017 INFINITI QX60

We bought the car used at about 24,000 miles. No engine lights were on. After about a month of owning it smoke would come from the exhaust when started. Took it in to be look at and was told it was a fuel injector and it was replaced. No more issues for about 6 months when it suddenly lost power on the interstate at dawn barley made it to the side of the road without getting ran over. Had to have it towed to a shop where I was told it was a bad coil and they replaced it. Went to pick the car up and less than a mile down the road it lost power again. Took it down for Infiniti to look at it. They said it had previously had engine sludge and that the warranty was voided because of it. After online searches, this seems to be a regular occurrence for this year and model. They recommend a new Engine for $14,000. Now stuck with a vehicle that won’t run with a monthly payment I’m making on it.
