Chrysler Recalls Jeep SUVs For Ignition Switches

The ignition switch defects that engulfed General Motors are now a rapidly growing problem at Chrysler. Chrysler said Tuesday it is recalling up to 792,300 older Jeep SUVs worldwide because the ignition switches could fall out of the "run" position, shutting off the engine and disabling air bags as well as power-assisted steering and braking. That's the same problem that has forced GM to recall more than 15 million cars over the last six months. Chrysler's recall covers 2005-2007 Grand Cherokees and 2006-2007 Commanders. The company said it is not sure exactly how many will be recalled, but said it will notify customers by mid-September. Chrysler said an outside force such as a driver's knee can knock switches out of the "run" position. Engineers are working on a fix. The Auburn Hills, Michigan-based automaker, now part of Fiat Chrysler Automobiles NV, said it knows of no related injuries and only one accident. But it said owners should keep clearance between their knees and keys until repairs are made. Chrysler has now recalled more than 1.7 million vehicles for ignition-switch problems. In June, the company added 696,000 minivans and SUVs to a 2011 recall to fix faulty ignition switches. Those recalls covered Dodge Journey SUVs and Chrysler Town & Country, Dodge Caravan and Volkswagen Routan minivans - which Chrysler made for the German automaker - from the 2007 to 2010 model years. Tuesday's recall is the outgrowth of two investigations opened by U.S. safety regulators last month as part of a broader probe into ignition-switch and air-bag problems across the auto industry. The agency wouldn't say Tuesday whether its investigation could lead to recalls at other automakers. The National Highway Traffic Safety Administration said in June that it was investigating Jeep Commanders and Grand Cherokees after getting 32 complaints that a driver's knee can hit the key fob or key chain, causing the ignition switch to move out of position. The federal investigation is still open. The agency said Tuesday that it is requesting additional information from Chrysler to ensure that its repairs will be effective. The investigations and recalls come after GM bungled an ignition-switch recall of older small cars. GM acknowledged that it knew of the ignition problem for more than a decade but failed to recall the cars until earlier this year, when it recalled 2.6 million small cars such as the Chevrolet Cobalt.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

'84 MotorWeek Cherokee, Bronco and Blazer comparison indulges your SUV nostalgia

These days, truck-based, full-frame SUVs are somewhat of a rarity on the auto landscape due to the rapid rise in popularity of easier-driving, car-based crossovers. Although, without the gradually building popularity of these chunky, high-riding vehicles decades ago, it's unlikely that America's roads would be filled with so many CUVs today. In its latest dig into the archives, MotorWeek has found a 1984 comparison test of a trio of these early Sport Utility Wagons, as long-time host John Davis called them, that helped get acceptance of this segment going. This is a red, white and blue test of the SUVs from American automakers at the time and pits the Chevrolet Blazer, Ford Bronco and Jeep Cherokee (specifically in Wagoneer guise) against each other. Driving manners and interior usability are considered in the evaluation, but Motorweek actually takes these vehicles off road, too. Among the bigger revelations is the improvement in on-road ability in the past 30 years. While specific 0-60 times aren't given, all three models take around 10 seconds just to get to around 50 miles per hour in the 500-feet on-ramp acceleration test. Check out this clip to see just how far this segment has progressed in the past three decades or just get a blast of nostalgia from these now vintage models.
