Completion-Rate Incentives

August 31, 2015 , Auburn Hills, Mich. – FCA US LLC has begun contacting customers who are eligible for certain recall-completion incentives.

Ranging from $100 prepaid cards to vehicle-repurchase plans, the incentives are designed to boost completion rates for certain ongoing recalls involving older SUVs and model-year 2009-2012 trucks, for which remedies were not immediately available.

“Remedies are available, we are servicing vehicles and we encourage affected customers to contact their dealers,” says Scott Kunselman, Senior Vice President – Vehicle Safety and Regulatory Compliance. “It is imperative that all vehicles implicated by recalls are inspected and serviced, as required.”

Mailings to incentive-eligible customers affected by NHTSA recall 13V-252 (FCA US N45 and N46) are complete. The offers therein pertain to 1993-1998 Jeep Grand Cherokee and 2002-2007 Jeep Liberty SUVs that were unremedied as of July 24, 2015.

Information about a vehicle’s eligibility may be determined by inputting its Vehicle Identification Number (VIN) into the search engines at any of the following sites:

– www.MyJeepAuto.com – www.recalls.mopar.com – www.safercar.gov

If its status is “open,” it is unremedied and therefore eligible.

A vehicle’s VIN can be found at the base of its windshield – on the driver’s side – or on the placard affixed to the driver’s-side doorjamb. The placard also indicates when the vehicle was assembled.

Owners of the affected Grand Cherokee vehicles may choose one of two options: – Receive a $100 Visa Prepaid Card for unrestricted use upon completion of recall-related service. (Customers who had their recalls completed on or after July 24, 2015, also are entitled to receive the prepaid card.) – Trade in the vehicle and receive a $1,000 incentive toward the purchase of a new vehicle, or a $1,000 Visa Prepaid Card usable for parts or service at the FCA US dealership accepting the trade-in.

Owners of the affected Liberty SUVs will, on completion of the recall-related service, receive a $100 Visa Prepaid Card for unrestricted use.

Mailings to eligible customers affected by NHTSA recalls 13V-038, 13V-527 and 13V-529 (FCA US N08, R16 and N49, respectively) began today. The offers therein pertain to the following vehicles, provided they were unremedied as of July 24, 2015:

– 2009 Chrysler Aspen and Dodge Durango SUVs produced from Jan. 3, 2008, through Dec. 18, 2008 – 2009-2012 Dodge Ram/Ram 1500 pickups produced from Feb. 27, 2008, through June 30, 2009; and from Dec. 1, 2009, through Oct. 20, 2011 – 2009-2011 Dodge Dakota pickups produced from Feb. 27, 2007, through June 30, 2009; and from Dec. 1, 2009, through Sept. 30, 2011 – 2008-2012 Dodge Ram/Ram 2500 and 3500 4×4 pickups – 2008-2012 Dodge Ram/Ram 2500 4×2 Cab Chassis vehicles – 2008 Dodge Ram/Ram Mega Cab 4×4 pickups – 2008-2012 Dodge Ram/Ram 4500 and 5500 trucks produced from Feb. 20, 2007, through December 2012

Owners of eligible vehicles from the above list may schedule service and, upon completion, receive a $100 Visa PrePaid Card for unrestricted use. Customers who had their recalls completed on or after July 24, 2015, also are entitled to receive the prepaid card.

Alternately, customers may negotiate trade-ins on new vehicles – a program that expires at midnight, Jan. 4, 2016 – or opt for a repurchase plan that, like the prepaid card incentives, has no expiry date.

Information about a vehicle’s eligibility may be determined by inputting its VIN into the search engines at www.recalls.mopar.com or www.safercar.gov. If its status is “open,” it is unremedied and therefore eligible.

To take advantage of the trade-in offer, a customer and dealer establish a value for the trade-in vehicle, complete the purchase of a new vehicle and receive – in addition to all current applicable incentives – a $2,000 incentive on a Ram-brand vehicle or $1,000 on a Chrysler, Jeep, Dodge or Fiat vehicle.

To participate in the repurchase program, customers are instructed – beginning Sept. 1, 2015 – to visit www.fcarecall.com. There they will see a preliminary estimated value of their vehicles, according to “good” market value, plus 10%.

Modification costs are excluded unless verification is provided to show the modification was part of the original purchase.

Beginning Oct. 1, 2015, customers may contact dealers to arrange for vehicle inspections. Dealers will then call a third-party administrator to complete the inspection and present a final offer to customers, who then have three options:

– Opt for the recall repair and receive a $100 Visa Prepaid Card for unrestricted use – Accept the repurchase offer – Opt for the trade-in incentive, which is available through Jan. 4, 2016

“We are committed to further improving our recall completion rates,” Kunselman says. “The added benefit of our efforts, we hope, will be to elevate public awareness of the need to respond to recall notices, and a greater understanding of the recall process, in general.”

FCA US has completed its 30-day deliverables under its Consent Order with the U.S. National Highway Traffic Safety Administration. In addition to the launch of the incentive programs, these deliverables included the selection of a third-party consultant – Deloitte – to conduct a comprehensive review and evaluation of the Company’s existing processes and procedures for compliance with NHTSA regulations and assist in the development of best practices.

September 1, 2015 , Auburn Hills, Mich. – Already unique among V-6 engines for its refinement, power, efficiency and adaptability, the formidable 3.6-liter Pentastar is remade for model-year 2016.

Depending on the application, the redesigned V-6 delivers fuel-economy improvements of more than six percent while increasing torque more than 14.9 percent. This occurs at engine speeds below 3,000 rpm, where elevated torque has its most profound impact on the driving experience.

Enhancements such as two-step variable valve lift (VVL), cooled exhaust-gas recirculation (EGR) and innovative weight-reduction strategies boost the engine’s efficiency and performance, all while preserving the smoothness that remains a hallmark of the Pentastar brand.

“With more than five million Pentastars on the road, we have clearly struck a chord in the marketplace,” says Bob Lee, FCA North America Vice President — Engine, Powertrain and Electrified Propulsion and Systems Engineering. “Such success brings enormous responsibility. Accordingly, we focused our efforts on improving efficiency and providing greater customer satisfaction in a package that delivers superior value.”

Features Increased fuel-efficiency was a key impetus in the development of the redesigned 3.6-liter Pentastar V-6 engine. FCA US LLC powertrain engineers evaluated multiple technologies, accumulating more than 4.7 million customer-equivalent miles using computer simulation and physical tests.

Improvements were measured right down to the component level. And no improvement was too small to chase.

Ultimately, the team identified the combination of features that deliver the greatest benefits in the widest operating range.

Arguably the most compelling enhancement is two-step VVL. The system is designed to remain mostly in low-lift mode until the customer demands more power; then it responds by switching to high-lift mode for improved combustion.

The result is less overall pumping work, which on its own, accounts for a fuel-economy improvement of up to 2.7 percent, compared with the 3.6-liter Pentastar’s previous iteration, named three times to the prestigious annual list of Ward’s 10 Best Engines.

The addition of cooled EGR firmly establishes the redesigned Pentastar among the V-6 elite. In addition to the obvious emissions-reduction benefits, the system further cuts pumping losses and enables knock-free operation at higher, real-world loads.

This translates to a fuel-economy improvement, on its own, of up to 0.8 percent.

Pumping losses are again targeted with the engine’s upgraded Variable Valve Timing (VVT) system. For 2016, it moves to torque-driven cam-phasing, which reduces oil demand.

The new VVT system also increases its range of authority to 70 degrees, from 50 degrees. This helps mitigate knock during hot starts and expands the operating envelope of Engine Stop Start (ESS), a fuel-saving feature that is carried over from the previous-generation 3.6-liter Pentastar.

ESS is driven by a high-speed/high-durability starter that reduces crank time for quicker restarts.

The system is regulated by algorithms, which act on the vehicle’s powertrain and chassis components.

As a result, acceleration is always aligned with driver inputs. Passive accelerator application is met with measured throttle response; hard inputs trigger aggressive starts. And there’s no waiting for either.

The same can be said for torque. More torque is delivered more quickly by recalibrating the VVT system to leverage the benefits of the new intake manifold’s longer runners.

The result is a torque boost of more than 14.9 percent, depending on the vehicle application. And this occurs between 1,000 and 3,000 rpm – engine speeds most customers see very frequently.

Says Lee: “We are particularly proud of this achievement because our engineering philosophy revolves around knowing our customers and anticipating their needs and wants. The new 3.6-liter Pentastar delivers a driving experience that is exhilarating.”

Function The redesigned 3.6-liter Pentastar V-6 engine benefits from numerous upgrades which better harness the combustion event. The upshot is improved efficiency.

Most notably, the engine’s compression ratio jumps to 11.3:1 from 10.2:1, compared with the engine’s previous iteration.

High-tumble intake ports combine with shrouded valves to take advantage of the engine’s new fuel injectors. Featuring eight holes each, twice the number in the previous iteration’s injectors, they offer optimized atomization and targeting.

Factor in the effect of 100-millijoule high-energy ignition coils with platinum sparkplugs and the above combustion enhancements account for a 1.5-percent improvement in fuel economy.

Multiple friction-reduction strategies contribute to an additional one-percent fuel-economy hike, compared with the engine’s previous iteration.

Particularly notable is the use of HG-R1 on the timing drive guide-faces. The new Pentastar is the first production engine to feature this low-friction material.

Also contributing to friction reduction are new valve springs, low-tension piston rings and piston pins which feature diamond- like carbon coating.

Form Just as refinement is a defining trait of the Pentastar V-6 engine family, so is component design. Its integrated exhaust manifold contributes to packaging efficiencies that enable plug-and-play-type integration across a formidable range of vehicle segments and drivetrain configurations.

The new 3.6-liter Pentastar debuts on the 2016 Jeep Grand Cherokee, the world’s most-awarded SUV. The new intake manifold improves airflow, which benefits volumetric efficiency and enables a boost of up to 295 horsepower, from 290 horsepower.

For model-year 2016, FCA US powertrain engineers were challenged by the potential negative effects of incremental weight wrought by the engine’s new feature content. However, clever component redesign produced an engine that weighs as little as 326 pounds, depending on the application.

That’s four pounds less than the previous 3.6-liter Pentastar, despite the addition of new content weighing 13 pounds.

A thin-wall strategy was used to reduce the nominal thickness of certain die-cast components – without compromising the noise, vibration and harshness (NVH) characteristics for which Pentastar engines are known.

Windage-tray weight was slashed by 19 percent and front-cover weight was cut by five percent. Two-piece oil pans were eliminated, with the exception of Trail Rated vehicles.

The engine’s crankshaft also went on a diet. Its main bearings and pins were trimmed, which contributed to an overall block-assembly weight reduction of six pounds. This generates additional friction-reduction.

“Our customers have made clear their profound appreciation for the 3.6-liter Pentastar,” Lee says. “We feel the upgraded Pentastar will evoke similarly strong emotions.”

Finale Model-year 2016 brings to FCA US showrooms a crossover that offers a drivetrain with capability no other vehicle in its class can claim. The all-new Fiat 500X features rear-axle disconnect technology that is unique to the FCA US stable of front-wheel-drive-based vehicles.

It disconnects and reconnects the rear axle – automatically and seamlessly – as needed and at any speed.

When driving conditions warrant only front-wheel-drive, the rear axle disconnects at both the PTU and rear-drive module, which improves fuel economy by reducing the parasitic loss, which occurs with conventional systems.

For model-year 2016, FCA US engines – except for the 8.4-liter V-10 that powers the Dodge SRT Viper – will be E15-compatible in anticipation of the fuel’s proliferation.

About FCA North America Powertrain Rejuvenated when the Company was established in 2009, FCA US powertrain organization has intensified its efforts to develop engines that deliver superior performance, improved fuel economy, reliability and driving enjoyment. Since 2009, nearly half of Chrysler Group’s total manufacturing outlay (more than $2 billion) has been invested in powertrain projects.
