Chrysler recalling hundreds of thousands of Jeep Grand Cherokee and Commander SUVs

The public might associated ignition switch recalls with General Motors - and with good cause - but that's not the only automaker calling its vehicles back in to fix that sort of issue.
Last month we reported that the National Highway Traffic Safety Administration was investigating an array of Chrysler Group vehicles for electrical-related safety issues. The administration and Chrysler subsequently issued a recall for 700,000 Dodge Journey crossovers, Dodge Grand Caravan minivans and Chrysler Town & Country minivans. But while the Jeeps that were also under investigation were not covered in that recall, they are being addressed in a separate one now.
Although Chrysler reports that it is only aware of a single accident stemming from this issue, it is "committing now to conduct a recall out of an abundance of caution." The recall affects the 2006-2007 Jeep Commander and 2005-2007 Jeep Grand Cherokee, of which it reports there are 792,300 on the road: 649,900 in the United States, 28,800 in Canada, 12,800 in Mexico and a further 100,800 outside of North America.

All hail the Hellephant, Mopar's 1,000-horsepower crate engine

It's shocking to say this, but the all-powerful Dodge Demon looks weak now that Mopar has unleashed the Hellephant. This crate motor makes 1,000 horsepower and 950 pound-feet of torque, and its name is a combination of the nickname for the old 426-cubic-inch Hemi V8 and, obviously, the Hellcat. This monster is a 426-cubic-inch version of the current third-generation Hemi V8 topped by a supercharger similar to what the Hellcat line packs. Everything is cranked up to — or perhaps, past — 11. The engine block is made of aluminum and weighs 100 pounds less than the equivalent iron block. All of the internals are forged. The stroke and bore have been increased. The supercharger produces 15 pounds of boost and displaces 3 liters; more than the 2.7-liter blower on the Demon and the 2.4-liter blower on the Hellcat. And as big and powerful as it is, it will still rev to 7,000 rpm. It's a thoroughly monstrous motor, but shockingly, it won't be that difficult to live with. For one thing, Mopar will offer a complete kit to get the engine up and running, including an engine computer, wiring harness and drive-by-wire throttle. It also runs on 93-octane pump gas. That's especially amazing considering the Demon engine "only" makes 840 horsepower, and that's on race gas with 100+ octane fuel. It also has us wondering what the Hellephant could make on racing fuel. The Mopar folks did say that there's room to add more power. Pricing wasn't announced for the Hellephant engine. The Hellcat crate engine retails at $19,350 directly from Mopar, so it's safe to assume that the Hellephant will go for more. The installation kit with the computer and harness will be an extra charge of likely over $2,000, based on the Hellcat kit. The engine and the kit will be available in the first quarter of 2019.

2021 Ram 1500 TRX Suspension Deep Dive | Underbelly of the beast

I think we can all agree that we have been waiting for a gonzo full-size truck like the 2021 Ram 1500 TRX for a long time. After all, it has been over a decade since the Ford F-150 Raptor came out, and it was such an immediate hit that I expected its direct competitors to respond much sooner than this. We all knew something was finally brewing in 2016, when the TRX concept was unveiled at the Texas State Fair. I was there, and was among the many who gave the assembled Ram higher-ups an enthusiastic thumbs-up. That’s what they were hoping to see before they greenlit the project. The pace of development being what it is, and with the redesigned, current-generation Ram 1500 a prerequisite that understandably had to come first, itÂ’s no surprise that weÂ’re only seeing it now as a 2021 model. You may be biting your tongue that I overlooked the Tundra TRD Pro or the Chevrolet Silverado Trail Boss, but neither of those comes close to following the formula established by the Raptor: big engine, a much wider stance than the base truck, greatly enhanced suspension travel, huge tires and swollen fenders to cover it all. Only the Raptor and the TRX fit that mold. For now.   Before I got started, I first pointed the TRX up my RTI ramp and measured its Flex Index score. Please excuse the shaded nose; the truck ran farther up than IÂ’d guessed and literally drove out of the picture. But something in my subconscious warned me to keep the garage door open, which was fortuitous because the nose of the Ram ended up inside. The TRX hiked its front wheel 29 and 7/8 inches off the ground before the left rear tire reached the point of lift-off, and that equates to a climb of 87.4 inches up the deck of my ramp. Divide that by the TRXÂ’s wheelbase of 145.1 inches, multiply by 1,000, and you arrive at a Flex Index score of 602 points. It could have been a few points higher, I think, if I could have straightened out the steering a bit better. But the high-grip cheese grater surface of my ramp was firmly dug in and having none of it. This is an extremely good score for a full-size crew cab pickup. LetÂ’s take a closer look at what made that possible.   The track width of the TRXÂ’s double wishbone front-suspension is a full 6 inches broader than a regular Ram 1500, and you are looking at the parts that are responsible. The lower wishbone (yellow arrow), the upper control arm (green) and the steering knuckle (red) conspire to add 3 inches per side to the TRXÂ’s stance.
