The cause of this issue is the GSM, manufactured Ficosa International, S.A.of Spain. Wide build tolerances within the Supervisor Microcontroller (SMC) inside the Gear Shift Module can allow temperature to affect the data transfer rates. When the data transfer rate of the SMC becomes desynchronized with the Main Microcontroller (MMC), the GSM resets and signals to the transmission may be delayed. This can result in an inability to get the vehicle out of park and/or the transmission not receiving, or there is a delay to receive, the intended gear selection.
To fix the problem, Fiat will replace the GSM or reflash vehicles with updated GSM software as necessary.
The cars affected are Fiat 500L models built between April 3, 2013, through February 14, 2014 (MDH 040300 through 021400)* equipped with the C635 dual dry clutch automatic transmission (sales code DA1). This amounts to approximately 19,500 cars (18,100 in the U.S. and 1,400 in Canada) and according to Fiat, some 20 percent are still in Fiat Studios inventory.
Fiat says an estimated 200 vehicles out of the total may require shift-module replacement to ensure hardware-software compatibility.
Owners of Fiat 500L models affected are expected to begin receiving notification by mail in April. The campaign is called Fiat 500L Recall P06. Owners concerned about the Fiat 500L recall may call 1-800-853-1403.
Here is timeline of significant events leading up to the recall of Fiat 500L.
• On October 23, 2013, Chrysler Vehicle Integration opened an investigation into reports of PRNDL lights flickering and shift delays. Regulatory Affairs was notified on December 2, 2013.
• On January 15, 2014, data from the Gear Shift Module (GSM) supplier showed inconsistent data transfer rates between two in-system microcontrollers with various GSM software levels.
• On January 27, 2014, Chrysler program team began recording vehicle Controller Area Network (CAN) log data from vehicles exhibiting the conditions after they were cold soaked in the environmental chamber.
• The root cause is determined to be wide tolerances of the internal oscillator within the Supervisor Microcontroller (SMC) internal to the GSM, allowing temperature to affect the internal oscillator rate of the SMC.
• When the oscillator rate of the SMC changes, it may become desynchronized with the Main Microcontroller (MMC), causing the GSM to reset and signals to the transmission may be delayed.
• As a result, shift requests made by the driver during this time may lead to vehicles moving in an unintended or unexpected direction.
• The scope of affected vehicles was determined to be all 2014 MY Fiat 500L vehicles produced with GSM software versions 120, 124, and 125.
• The suspect period was established as April 5, 2013 to January 22, 2014 at Fiat Automobile Serbia (Kragujevac- Z) Assembly Plant.
• As of February 20, 2014, Chrysler identified approximately 16 CAIRs, 2 VOQs and 89 field reports related to this issue.
• As of February 20, 2014, Chrysler is unaware of any accidents or injuries potentially related to this issue.
• On February 25, 2014, Chrysler determined, through the Vehicle Regulations Committee, to conduct a voluntary safety recall.
About the Dual Dry Clutch Transmission
The C635 Dual Dry Clutch Transmission (DDCT) used on the Fiat 500L was developed by Fiat Powertrain Technologies (FPT) and uses a BorgWarner hydraulic actuation module. At the time of its introduction in 2010 on the Alfa Romeo MiTo, the robust transmission held the distinction of having the highest torque capacity of any DDCT transmission available on the market. The Fiat DDCT was designed to be compact and adaptable to allow its use in a multitude of cars, from the Dodge Dart to the high performance Alfa Romeo 4C sports car.
The advantages of using a dual dry clutch over a wet clutch setup is substantially increased efficiency and the elimination of the heavy and complex hydraulic support systems. The tangible results are significant savings in fuel consumption of more than ten percent when compared to the wet clutch and up to six percent in comparison to manual transmissions. The lightweight yet stout C635 DDCT weighs in at 179 lbs including oil and the transmission control unit and the design has been awarded 23 patents. The transmission is manufactured at the FPT facility in Verone, Italy.

Fiat is unveiling at the Geneva Motor Show this week a new extreme performance version of its Fiat 500 Abarth called the Abarth 695 biposto. Biposto means "two seater," but it's anything but a trim package. The Abarth 695 biposto is billed as the ‘fastest street legal Abarth ever.’ Starting with an Abarth 695, the company adds a just about everything an Abarth enthusiast would want: front intercooler, Akrapovic exhaust system, Extreme Shox adjustable shock absorbers, MXL digital data logger, Abarth Corsa by Sabelt seats with 4-point seat belts, Brembo braking system, lightened 18-inch OZ rims and rear titanium roll bar by Poggipolini.
But there is more, upon request Abarth tosses the standard heavy duty C510 transmission and installs an extreme performance transmission modified with dog rings in place of synchronizers enabling a skilled driver to shift without the clutch. A self-locking clutch-plate type differential keeps the 215/35 R18 tires mounted on the unique 18 inch OZ Racing wheels from going up in smoke.
To maximize performance, the car is lightened and forgoes rear seats, xenon headlights, fog lights, climate control, electric windows and radio system. Side windows are made of lightweight yet strong polycarbonate, a material first used on a road car for the rear quarter window of the Fiat 500L. A mean looking body kit from Zender sports new front and rear fascias, sideskirts, wheel arches and spoiler and contributes to a total weight reduction of approximately 176 lbs (2198 compared to 2374).
The engine takes the standard Abarth 695 1.4 liter TJet rated at 180 HP and bumps it another 10 to 190 HP. This gives the Abarth 695 biposto the best power to weight ratio in its class (11.6 lbs/HP or 5.2kg/HP) and the best acceleration, hitting 0 to 62 mph in just 5.9 seconds.
While we won't see the Abarth 695 biposto here in North America, you can bet it will give Abarth enthusiasts on this side of the Atlantic inspiration to create their own interpretation. Check out the Fiat 500 USA Abarth Forum for a look at some of the hottest Abarths in North America.
• Special kits to ensure maximum customization
The Fiat Abarth 695 was the ultimate Nuova Fiat 500 in its era. The new Abarth 695 pays tribute to this car.
