Car has been running perfect for 1,500 miles. I check her oil every time I start her. Have had to add a quart since break-in, but other than that she's been amazing. Then out of the blue, check engine light comes on when I get out of my hand wash place. Here's what her symptoms are...what could it be? She won't rev under load over 2,000 rpms. The Supercharger won't engage. And when I was pulling her into my parking spot, I can hear a metallic scrapping noise, almost metal scrapping against metal. And it's my birthday today. So bummed. She's getting towed tomorrow to Manhattan Jeep Chrysler Dodge at 8am. What sucks is the service guy there said since it's a specialized vehicle, they may not get to her until Tuesday/Wednesday. Nothing else I can really do other than let Dodge and their guys diagnose and fix her. No use yelling or screaming about it. Just bummed because engine issues so early on has me really worried. I won't lie guys...I feel like selling her. In the past when I've had early engine issues, they persisted. What do you think is wrong?
