If you are having issues, check your batteries if have not done so. A low battery will cause all sorts of issues to appear and then go away and appear again. Also, make sure your car is always on a tender when not driven.

When I first bought my 458, I had intermittent issues pop up. The car started fine, ran well and was on a tender when not driven (meaning when I was done with a drive, the car was on the tender until the next time I took it out). I changed the battery and all the issues went away. Keep in mind it was the factory battery and was going on 4-5 years old. Actually surprised it lasted that long.

If the battery is good, you can disconnect it for 5 mins or longer and then reconnect and go through the restart procedure. The ambient air temperature needs to be above 41 degrees F.

The following is from the owners manual (it is actually in a few different areas of the owners manual)

Disconnect Procedure

- Put windows down at least 2-3cm or more
- Make sure that consumers are turned off (i.e. lights, windshield wipers, radio, etc.)
- Turn AC off
- Remove the negative terminal clamp and place so that it does not come in contact with the negative terminal or with any metal on the car

Connect and Re-learn Procedure

- Temperature must be above 41 degrees F
- Connect negative cable to negative post of battery
- Close doors and leave vehicle alone for at least one minute
- Before starting engine, ensure all doors, engine and luggage compartment lids are closed
- DO NOT switch on any consumers during this period
- After one minute or so, lock/unlock doors with remote (you should be standing outside of the car)
- Open the luggage compartment lid by pressing the button twice on the remote
- Insert key in ignition and turn to position II and WAIT AT LEAST ONE (1) MINUTE before starting engine
- Start engine
- Leave the engine stationary for approximately 10 mins in the following conditions:
- Engine at idle speed
- Water temperature stabilized
- Consumers switched off (do not turn them on)
- A/C off
- Close doors and raise the windows to the upper limit and then lower windows. Raise them again and check that they move down to the target position when the doors are opened
- Lower and raise rear window (spider only)
- Set date and time on instrument panel

If you fail to follow the procedure above as described in the owners manual, the car will implode and turn into a pile of mush....

The owners manual is a wonderful tool.....
