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.

MotorWeek revisits the awesome, original Dodge Viper

MotorWeek is bringing the automotive world a wonderful blast from the past with its latest Retro Review. Not only does the video feature the now-famous, original Dodge Viper, but this is also a chance to watch one lapping Pocono International Raceway in a test of track prowess. This segment was MotorWeek's first chance to unleash the Viper around a racecourse, and the show took advantage of the opportunity. In addition to the usual 0-60 mph and quarter-mile tests, the 400-horsepower V10 is let loose to do lap after lap. The clip offers a great dose of nostalgia and is worth a watch to remember the intense enthusiasm surrounding the Viper at the time.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
