25,000 Jeep Grand Cherokee, Dodge Durango SUVs recalled over brake feel

Chrysler has announced that it is recalling over 25,000 Jeep Grand Cherokee and Dodge Durango SUVs from several markets over concerns about brake feel under hard braking. The affected models are from the 2012 and 2013 model years, although the actual dates of production aren't available. 18,700 are in the US, while 825 are in Canada, 530 are in Mexico and a further 5,200 outside of North America.
According to a statement, Chrysler was informed of the issue by a component supplier for the Ready Alert Braking system, which primes the brakes in anticipation of an emergency stop. A component in the system was restricting the flow of brake fluid too much.
As Chrysler is quick to point out, the way the brakes functioned was in compliance with regulations and there are no reported cases of drivers losing braking power. Instead, the issue rests with what Chrysler calls a pedal feel that "was not consistent with customer expectations." So it would seem Chrysler is being proactive and fixing a problem not because there's a legal issue at work, but simply because it doesn't feel the way the manufacturer wants it to. Well done.

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.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
