2017 Jeep Grand Cherokee Trailhawk Quick Spin

Jeep won't come out and say it, but the 2017 Grand Cherokee Trailhawk exists to bloody the nose of the Toyota 4Runner TRD Pro. America's off-road brand hasn't built a wheeling-specific version of its Grand Cherokee flagship in years, and the last GC Trailhawk was mostly stickers and tires. It was time for a true trail-spec Grand Cherokee again. We took a quick spin (two of them, actually) in the latest Trailhawk model, which joins Renegades and Cherokees with the same badge and off-road bent for 2017. Our time was limited, and so were our initial findings. After driving on and off pavement at Fiat Chrysler's proving grounds in Chelsea, Michigan, we can tell you that on the road, this Grand Cherokee has the same refined driving dynamics as any other. As for off-roading, the capability is still somewhat of an open question. Driving Notes The suspension and off-road system tuning are what really set the Trailhawk apart from other Grand Cherokees. Jeep tweaked the four-corner Quadra-Lift air suspension to improve articulation and suspension travel, while retaining the 10.8 inches of ground clearance of lesser Quadra-Lift Grand Cherokees. Paired with the standard Quadra-Drive II four-wheel-drive system, rear electronic limited-slip diff, and 20-inch Goodyear Adventure off-road tires, the Trailhawk is not short on capability (at least on paper). Unfortunately, paper is almost where this stops. The Trailhawks we drove were pre-production models with unfinished software calibrations. The throttle on the 3.6-liter V6 Trailhawk we took on the off-road course was super touchy and hard to modulate, regardless of which Selec-Terrain off-road mode was selected. Without a reliable throttle, we were bounding over obstacles instead of negotiating them patiently. This was back in June, and Jeep's PR reps assured us at the time that the engineers knew about the oversensitive throttle and have since confirmed that the issue has been fixed for production models, which are rolling off the line in Detroit now. We're planning to get into one of those vehicles as soon as one becomes available for a full review. Like the standard model, the Trailhawk's air suspension offers more comfort than the double-wishbone front and four-link rear suspension on the 4Runner.

Feds fretting over remote hack of Jeep Cherokee

A cyber-security gap that allowed for the remote hacking of a Jeep Cherokee has federal officials concerned. An associate administrator with the National Highway Traffic Safety Administration said Thursday that news of the breach conducted by researchers Chris Valasek and Charlie Miller had "floated around the entire federal government." "The Homeland Security folks sent out broadcasts that, 'Here's an issue that needs to be addressed,'" said Nathaniel Beuse, an associate administrator with the National Highway Traffic Safety Administration. Valasek and Miller commandeered remote control of the Cherokee through a security flaw in the cellular connection to the car's Uconnect infotainment system. From his Pittsburgh home, Valasek manipulated critical safety inputs, such as transmission function, on Miller's Jeep as he drove along a highway near St. Louis, MO. The scope of the remote breach is believed to be the first of its kind. The prominent cyber-security researchers needed no prior access to the vehicle to perform the hack, and the scope of the remote breach is believed to be the first of its kind. A NHTSA spokesperson said the agency's cyber-security staff members are "putting their expertise to work assessing this threat and the response, and we will take action if we determine it's necessary to protect safety." A Homeland Security spokesperson referred questions about the hack to Chrysler. Fiat Chrysler Automobiles has already been the subject of a federal hearing this month, in which officials scrutinized whether the company had adequately fixed recalled vehicles and repeatedly failed to notify the government about defects. But cyber-security concerns are a new and different species for the regulatory agency. Only hours before the Jeep hack was announced by Wired magazine earlier this week, NHTSA administrator Dr. Mark Rosekind said hacking vulnerabilities were a threat to privacy, safety, and the public's trust with new connected and autonomous technologies that allow vehicles to communicate. NHTSA outlined its response to the cyber-security challenges facing the industry in a report issued Tuesday. In it, the agency summarized its best practices for thwarting attacks and said it will analyze possible real-time infiltration responses. But the agency's ability to handle hackers may only go so far.

UAW workers in Indiana, Stellantis reach tentative deal to end strike

United Auto Workers union members who went on strike Saturday at the Stellantis casting plant in Indiana have reached a tentative deal with the company. The UAW Local 1166 bargaining committee announced a tentative agreement in a blog post, saying that a ratification vote would be held Monday. Stellantis confirmed the tentative deal Monday. The strike was related to health and safety issues, including the company’s alleged refusal to repair and replace the plantÂ’s air conditioning and heating systems. The 35-acre plant in Kokomo makes parts used in the power trains of Chrysler, Dodge, Jeep and RAM vehicles. The 1,200-worker plant, Kokomo Casting, is the worldÂ’s largest die cast facility, according to Stellantis. In May, Stellantis announced a $2.5 billion joint venture with Samsung to build an electric vehicle battery factory in Kokomo that is to employ 1,400 workers. Stellantis, created last year through the merger of Fiat Chrysler and FranceÂ’s PSA Peugeot, had said it would build two electric vehicle battery factories in North America. The other is slated for Windsor, Ontario. Plants/Manufacturing UAW/Unions Chrysler Dodge Jeep RAM
