Below is posted in the interest of providing information to the members and owners here. It seems very early build date Fiat 500s may have a starting issue due to poor grounding of the starter. This effects cars built over a three month period (approx 3,000 cars). Please consult your local Fiat Studio for specific information.
Customer Satisfaction Notification N15 Starter Motor Mounting Bolts
2012 (FF) Fiat 500
NOTE: This notification applies only to the above vehicles equipped with a manual transaxle (sales code DDF) built from March 15, 2011 through June 30, 2011 (MDH 031500 through 063023).
The starter motor mounting bolts on about 3,000 of the above vehicles may not ground the starter motor to the transaxle case properly. This could cause the electrical energy from the starter motor during cranking to take an alternate path to ground across the engine crankshaft bearings.
One starter motor mounting bolt must be replaced with a new starter motor bolt and a second starter motor mounting bolt must be added for grounding reasons only.
