I've had my Nitro R/T 4.0 engine for 11 mos. now and I've had a number of problems with it.Two weeks after I got it I noticed a like chattering noise from the engine. First they said serpentine belt. The noise got louder. My crankshaft bearing and pistons have been replaced. My Sirius radio has had 2 recalls. Needs new one. Heater doesn't work right. Now my roof rack has a recall on it.T hey are tired of working on it. Take it to another dealership. Sad thing it only has 9700 miles on it. What next?What will it be like in another year? Parking it is terrible too. Wider than my other SUV. Hard to see where you are in a parking space. Too much money too many headaches. Stay away! Not unless you want trouble?
