1.8 million Ram trucks recalled to fix shifter problem

Fiat Chrysler is recalling 1.8 million mostly heavy-duty Ram pickups to fix a part that could allow the truck to shift out of park and roll without depressing the brake pedal, a problem the automaker knows to be potentially related to seven injuries and a "small number" of accidents. The company says tests revealed that the interlock, which is supposed to keep the transmission from shifting out of park without the driver's foot on the brake and without a key in the ignition, may malfunction if subjected to high temperatures for long periods. The recall is limited to vehicles equipped with shifters mounted on the steering columns; those with rotary-dial shifters or floor-mounted shifters aren't affected, and model-year 2017 trucks built after Dec. 31, 2016, are excluded. Trucks covered by the recall are certain 2010-2017 Ram 2500 and 3500 pickups; 2011-2017 Ram 3500, 4500 and 5500 chassis cabs; and 2016 and 2017 Ram 3500 chassis cabs of less than 10,000 pounds gross vehicle weight. Certain 2009 through 2017 Ram 1500 pickups are also included in the recall. Most of the affected trucks are in the U.S., with the rest in Canada and Mexico, plus about 15,000 outside of the North American Free Trade zone. FCA recommends that customers always use parking brakes and not leave children unattended in parked cars.Related Video: Featured Gallery Mojave Road in a 2017 Ram 2500 Power Wagon View 31 Photos Recalls RAM Truck ram 5500 ram 4500

Maxwell RHEV Prototype First Drive Review | More than meets the eye

The Maxwell RHEV looks just like any small business' panel van, sporting large vinyl graphics and unassuming steel wheels. You'd have no idea that the co-founders of the startup based out of Seattle had grafted a salvaged Voltec powertrain from a junkyard Chevy Volt into this Ram ProMaster. Somewhere, a battery pack lurks. Maxwell's co-founders, CEO Max Pfeiffer and engineer Trey Camp, open the cargo area to reveal a completely unaltered space. Both are ex-Tesla employees with a long fascination for the #vanlife movement – that their interests intersected in a hybrid cargo van isn't surprising once you start talking to them. This is their first vehicle, a salvaged ProMaster sidelined with a blown 3.6-liter Pentastar, and it's both their prototype and the only Maxwell in existence right now. That said, the company is building a low-roof version for a customer, which will be lighter, have less aero drag and therefore be more efficient. The company is just emerging from a stealth startup mode, and while their backstory is fascinating, I'm still wondering where the Volt's 18.4 kWh battery pack is. "There's nothing in the back ... we're able to get the battery underneath the floor, in the center," Pfeiffer says. Ducking my head under the side reveals, sure enough, a little underside blister that contains the battery, tucked up neatly. The other changes to the RHEV – short for Range-extended Hybrid Electric Vehicle – are minimal. He pops the hood. There are some rough edges, but the 1.5-liter, 101-horsepower engine and 48-kW motor fit comfortably on custom engine mounts and with re-routed exhaust, behind a fascia that improves aero and houses the charge port. Custom axles send power to unaltered Ram hubs and brakes. "This version, it's a little bit prototype-y," Pfeiffer says. "We've had more time to work with the CAD [computer-aided design, engineering drawings] we were able to get from GM and Chrysler, and we've done a better job packaging for production." GM already spent billions on the Voltec and its controlling software, and Maxwell can happily ride those coattails. Despite the help GM has lent Maxwell, there are no official ties. An emulator sends spoofed signals to the Ram instruments, which have a new custom-printed face. The Ram's body control module is left alone. For powertrain faults, Maxwell says the vehicle can theoretically be serviced by any Chevy dealer, and any issue with the rest of the vehicle can be handled by a Ram service shop.
