While driving, the vehicle displayed an engine malfunction warning followed by a low oil pressure warning. I pulled over and waited. The oil level was checked and was not empty. The warning lights briefly went out, but shortly afterward the engine lost power. When attempting to restart the vehicle, the engine began knocking. The vehicle became inoperable and required towing. This was a sudden engine failure with no prior indication of oil loss, leak, or neglect. This created a safety concern due to sudden loss of power while driving.

A mechanic says it is PCM failure. I have owned the car for 18 months. Shortly after buying it, it started doing this thing where it loses power for just a second or two. Cruise control and proximity sensors kick off, steering wheel locks and/or power steering turns off, all interior components turn off. Usually everything comes right back on, and I can reset the cruise control. Lately it has been more frequent, and things don't go back to normal. It sometimes causes the vehicle to stall and not start as well. Today even once things are back "on", I can't control the AC fan, radio volume, etc. Bluetooth shows connected to the car on my phone but isn't playing through the vehicle speakers. I don't undersrand how this could not be a recall when it poses a major safety risk to suddenly lose power and be unable to steer the vehicle! This has been happening since Feb 2024, so I'll just put the original date. Sometimes it happens 15 times in a day and the vehicle is more or less not drivable. Other times I'll go a month or so with no glitches.

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.

The car has shut off twice while (once on the highway) and once on a side street. Lost power and locked up. Prior to the shut offs power flickered. No problem identified with Infiniti but appears so be a known issue amongst the infiniti community. Are these cars safe??????
