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.

How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

2019 Jeep Cherokee First Drive Review | Still the most truck-like crossover SUV

The history of the SUV has been one of ever-increasing refinement, and that arc bends towards carlike forms. It's a trend that even the hardiest of nameplates has succumbed to, including the venerable Cherokee, which for 2014, moved from the solid-axle brick of yore to the shark-nosed, independently suspended crossover of modern-day. That wasn't necessarily a bad thing. We found it to be quite a competitive machine at the time, and one that was plenty capable. But time marches on, and five model years later, Jeep has updated the Cherokee. The polarizing shark nose has been toned down, with all the headlight elements integrated into single units on either side. The hatchback has been revised and now sports a cutout for the license plate. Besides improving the looks at the back, Jeep says it allowed them to expand the rear cargo area to 25.8 cubic feet, an increase of 1.2 cubes, because moving the license plate space allowed them to pull the latch assembly farther out. It should be noted, though, that the Cherokee still doesn't have as much cargo capacity as the new 27.2-cubic-foot Compass. Besides the cosmetic changes, the new Cherokee gets a new engine, a 2.0-liter turbocharged four-cylinder good for 270 horsepower and 295 pound-feet of torque that shares commonality with the Jeep Wrangler and Alfa Romeo Giulia engines. However, it lacks the mild hybrid technology of the Wrangler because of space issues, and it has a cylinder head with two camshafts rather than the Alfa's single-overhead cam design. In addition to the new 2.0-liter turbocharged engine, the Cherokee's old naturally aspirated engines, a 2.4-liter four-cylinder (180 hp, 170 lb-ft) and a 3.2-liter V6 (271 hp, 239 lb-ft), carryover unchanged except for the addition of standard engine start-stop functionality. The question is, can mild changes to the Cherokee keep it competitive in a segment where several rivals have been completely redesigned? In terms of capability, the answer is a resounding, "yes," particularly for the Trailhawk, which in turbocharged guise, has even shorter gearing for its low-range four-wheel-drive setting than before at 51.2:1. Like the previous model, the Trailhawk includes different front and rear bumpers for improved clearance and approach and departure angles. It features a set of skid plates and gets a steel oil pan for protection from obstacles, and the rear axle can be locked for additional traction.
