Good morning I have a 2011 Infiniti QX56. It has been in the shop since last Monday. I had a bad alternator and battery. When I went to pick my vehicle up the service light engine was on which that wasn’t on before and it was driving a little rough. So the mechanics took a deeper dive and they’re saying that my cylinder #5 is the issue. I can still drive my SUV but they’re saying that they usually don’t fix one cylinder so they would rather replace the entire engine. My insurance company feels this may not be necessary and so do I. Has anyone else had an issue with cylinder #5 on your vehicle. It is drivable, I just don’t want necessary repairs being done when it could be a simple fix. Any suggestions?
