NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point.

Stellantis announces ‘Circular Economy’ business to drive revenue, decarbonization

Stellantis has already announced its plans to reach net-zero carbon emissions by 2038. Today, the automaker has announced a new business unit to help it reach that goal while generating 2 billion euros per year in revenue by 2030. The “Circular Economy” business will help make revenue less dependent on finite, rare and ecologically problematic materials. The Circular Economy model features what Stellantis calls a “4R” strategy, comprising remanufacturing, repair, reuse and recycling. The goal is to make materials last as long as they can, reducing reliance on the acquisition of those precious new materials in the future by returning them to the business loop when theyÂ’ve reached the end of their first life. Through these processes, Stellantis says it can save up to 80% raw material and 50% energy compared to manufacturing a new part. Remanufacturing, or “reman” in Stellantis shorthand, means dismantling, cleaning and rebuilding parts to OEM spec. Nearly 12,000 remanufactured parts are available for customers to purchase. Some remanufacturing is done in-house, and some with partners and through joint ventures. Repair is pretty obvious — fixing parts to put back into vehicles. This also consists of reconditioning, to make a vehicle feel like new. Stellantis boasts 21 “e-repair” centers for repairing electric vehicle batteries.  Reuse refers to parts still in good condition from end-of-life vehicles sold as-is. Stellantis says it has 4.5 million multi-brand parts in inventory. These are sold in 155 countries through the B-Parts e-commerce platform. Reuse also refers second-life options, such as using batteries outside of automotive purposes. Recycling involves dismantling parts and scraps back into raw material form that is then looped back into the manufacturing process. Stellantis says it has collected 1 million parts for recycling in the past six months. Recycling doesnÂ’t get counted in that aforementioned 2 billion euros of revenue, but it does save the company money on acquisition of raw materials. As for batteries, specifically, Stellantis expects this recycling business to ramp up after 2030, when the packs currently in service begin to reach the end of their lifecycle. Stellantis will use its new “SUSTAINera” label to denote parts that are offered as part of its Circular Economy business.
