Should I have any concerns about purchasing the first model Renegade. Are 1st edition vehicles more likely to have problems or is this just a myth. I know the engine and transmission are already used in other Jeeps and the body will be used from current Fiat models. Both fiat and jeep have been in business for 200 years combined which makes me feel a little better about making a purchase. Just wondering if anyone is holding off to make a purchase because of this or just going all in based on the companies histories.
There's no guarantees. There are basically two categories for systemic problems. Engineering problems, and problems with labor adapting to the requirements of manufacture.
Labor problems can be hashed out as production goes on. Engineering problems basically stick until a refresh or redesign.
My first concern is a new engine and/or transmission as they are both complex to design and assemble, and with tight tolerances compared to the rest of the car.
I've jumped into the first model year before. A 2005 Subaru legacy gt. It had the better part of a year production in Japan first, the engine had been out for over a year in a different model, and the transmission was a lightly modified version of one in several other cars with a good track record.
Biggest problem with it is how they engineered the dashboard retention. They didn't fix that until the 2008 model.
I had a couple issues with how stuff was assembled that were apparent in the first couple thousand miles and they were easy dealer fixes. They weren't common because they were labor issues that got sorted really quickly.
Probably the biggest risk are mid year changes for safety. They are relatively uncommon though.
