I went to Jem Auto for a simple tune-up. Change the spark plugs and ignition coils. They cross threaded my spark, and force them causing metal chippings from being forced got into my engine block and ruined my entire engine! He refused to take ownership and fix my vehicle. I have a BMW and the exit made it cost for my repair is $9,000. I have been without a car for 3 months now due to Jen Auto negligence and poor mechanical skills.
