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.

AEV Jeep Wrangler Unlimited Rubicon

After their rented 2007 Hummer H3 failed them during the brutal Rallye Aicha des Gazelles in Morocco, Amy Lerner and her sister Tricia Reina were on a quest to find the most capable production off-roader for their next competition - they chose a 2012 Jeep Wrangler Unlimited Rubicon. Their next mission was to find a company with the competence to configure it to win. After poring over Internet forums and perusing countless magazines for an outfitter who could meet their demanding requirements, they sent their bright orange JK ("Crush" is the official color) to American Expedition Vehicles (AEV) for some modifications.
The Michigan-based team at AEV kept the Jeep's 3.6-liter V6 and automatic transmission stock, but replaced the hood with a tall AEV Heat Reduction Hood and added an AEV Snorkel Kit for water crossings (it serves double-duty as its raised height helps to keep the air intake out of the kicked-up dust on the trail). Front and rear off-road bumpers were bolted in place, and AEV skid plates were added to provide additional undercarriage protection. A pair of IPF-900 off-road lights improve visibility, while a 10.2-gallon AEV Fuel Caddy (located behind the exterior spare) added some range. The suspension was upgraded with a 3.5-inch lift kit with Bilstein remote reservoir shocks, and 35-inch Falken Wildpeak A/T tires (LT285/70R17) were mounted at all four corners on AEV's beadlock wheels.

Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.
