On a long trip, outside the range of AAA to tow me home, I carry a CPS and Relay Control module and the tools to replace them. Do a search and you will find a lot of info on this site in regards to symptoms and repair of these issues.

In regards to spare /flat tires. many of us carry a small repair kit from Wal-Mart and a pair of needle nose tires. DO NOT use the fix-a-flat stuff from Chrysler or from the store. It will screw up your sensors in the wheels. Buy AAA tow coverage. Use the tire inflator in the trunk after tou use the repair kit.

Make sure you read in advance how to tow this car and check for your multi-use tool to truck.

I keep a spare 18 and 19 inch rim and tire in the garage. In case I really get stuck someplace.

Other may have other suggestions. This has been discussed often in the past. Try a key word search on this using the bold words.
