NHTSA investigates a million-plus Jeep Cherokees for parking brake issue

The National Highway Transportation Safety Administration (NHTSA) is investigating a potential safety issue that could be present in more than 1 million Jeep Cherokees sold for the 2014-2020 model years. Per owner complaints, these cars may be equipped with an electronic parking brake control module that is susceptible to water intrusion. If the water causes a short, it can result in uncommanded activation of the parking brake while the vehicle is in motion, which can lead to a stall, NHTSA says.  If you follow Jeep Cherokee news closely (and who doesn't?), this issue may ring a bell. That's because Jeep was on the hook for recalling the Cherokee for water intrusion into the liftgate control module, which is fitted right next to the parking brake module. In that instance, short circuits had the potential to cause a fire, which has not so far been indicated as a potential side effect of the new parking brake issue, but any time electricity is involved, there's usually at least some risk for ignition.  The Cherokee is just one of four Stellantis models with a new open investigation, the Detroit Free Press reported Tuesday. NHTSA is also looking into reports of a transmission problem that could strand owners of 2019-2021 Chrysler Pacifica plug-in hybrid minivans and a crankshaft and/or camshaft position sensor problem that could cause a stall in the 2016 Dodge Journey and Jeep Compass. Between the two, these investigations cover an additional 300,000 vehicles.  None of these vehicles are being recalled at this point, however a NHTSA investigation is the first major step toward a recall being initiated. The regulator will work with Stellantis to determine whether a recall is necessary.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences.

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.

Jay Leno gets his denim mitts on Dodge's new Challenger Hellcat

The 2015 Dodge Challenger SRT Hellcat is definitely the performance car of the moment. The fact that in the near future, people will be able to buy a 707-horsepower muscle machine straight from a major automaker for $59,995 and with a factory warranty almost seems absurd. We drove it recently and found the Hellcat to be just as much of a beast as its numbers would suggest. Now, it's a certain comedian's turn behind the wheel in the latest episode of Jay Leno's Garage.
This week's guest is Dodge President and CEO Tim Kuniskis, and he's there to drop all sorts of interesting factoids about the Hellcat. For example, its Pirelli P Zero tires retail at around $300 each, he says. That makes its smoky burnouts a rather expensive proposition. Kuniskis, who recently hinted at a mystery Woodward Dream Cruise debut, also talks about the genesis of the 2015 SRT project with a goal to get over some of the standard Challenger's weight and size disadvantages. The fix is a supercharged V8, massive brakes and other goodies to smooth over the platform's more glaring shortcomings.
Leno appears to get a big kick out of the Hellcat. However, he can't seem to stop bringing up his desire to drive one with a six-speed manual. They obviously exist, but Kuniskis has an eight-speed automatic for the retired Tonight Show host to try out. Of course, as with any Hellcat video, there has to be at least one burnout. Despite the expensive tires, it seems like enthusiast's law at this point - and dear ol' Jay wouldn't want to break any rules, would he?
