NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.

In our first encounter with the 2017 Jeep Grand Cherokee Trailhawk at Fiat Chrysler's Chelsea Proving Grounds, we saluted the new model's impressive on-road demeanor. In its off-road mode, however, we couldn't ignore the pre-production throttle calibration – it was super sharp and difficult to modulate with the precision needed to navigate obstacles. We were told then that Jeep's engineers were aware of the problem and were fixing it for production models. So we recently set off for Bundy Hill Off-Road Park in Jerome, Michigan, in a production-spec Grand Cherokee Trailhawk to check their work and get a better idea of the overall package. We can report that the Trailhawk's throttle has been fixed for production, landing it properly in Goldilocks territory. In the off-road Mud setting, the throttle is soft and easy to modulate. You can balance this rig with the gas pedal, reaching just past tip-in to steadily prod forward. But the gas pedal doesn't delay when you really need power. Move beyond the initial tip-in, and the engine responds quickly, which is a good thing, as a sluggish throttle is almost as dangerous off-road as one that's too sharp. Rock mode promises even more precise control over the throttle, although our lack of a spotter and a desire to avoid damaging the 700-mile-young Trailhawk kept us from hitting Bundy Hill's rockier sections. The wet, non-snowy weather meant we didn't properly test Snow or Sand mode. This test model was equipped with FCA's popular 3.6-liter V6, but like the rest of the Grand Cherokee range, more power is available from the 3.0-liter EcoDiesel V6 and the 5.7-liter Hemi V8. You don't need them – the 3.6-liter and eight-speed automatic are perfectly fine on the trails. Faced with an incline, the transmission holds its gear without complaint – you don't even need to switch into manual mode. Despite the 4,800-rpm torque peak, the V6's 260 pound-feet arrive early enough that you don't need to strong-arm the throttle. So that's resolution for the pre-production issue. But our time at Bundy Hill exposed a different and ultimately much easier to fix problem for the production model. Late fall in Michigan is not always a good time to go off-road – sub-40-degree temperatures and a steady, depressing drizzle can turn a relatively simple trail into a slippery mess of wet clay. Conditions like these can easily overwhelm an on-road tire like the Goodyear All-Terrain Adventures the Trailhawk uses.

Jeep Wrangler plug-in hybrid confirmed for 2020

The Jeep Wrangler will get a plug-in hybrid electric model in 2020, brand head Mike Manley confirmed this week at the Los Angeles Auto Show in a move he says is "future proofing" the legendary off-roader. "A full plug-in electric Jeep Wrangler will be available in 2020, furthering our commitment to all those who value the responsible, sustainable enjoyment of the great outdoors and very importantly, future proofing this Wrangler for generations to come," he said after the reveal of the 2018 model. It was reminiscent of a Steve Jobs 'One More Thing' moment from an Apple event. Manley explained the details of the new Wrangler, codenamed JL, and then dropped the EV nugget near the end of the press conference in Los Angeles. He didn't offer up further details like range or power. The plug-in hybrid will join a now-expansive powertrain lineup for new generation of the Wrangler. Jeep will offer a mild hybrid next year with its 2.0-liter turbo four-cylinder engine. Called eTorque, the hybrid adds regeneration, stop-start and electric power assist. This system makes 270 horsepower and 295 pound-feet of torque. In 2019, the Wrangler will get a 3.0-liter V6 EcoDiesel engine rated at 260 hp and 442 lb-ft. The tried-and-true Pentastar V6 with 285 hp and 260 lb-ft also continues. In an exclusive interview with Autoblog in January, Manley previewed the Wrangler's electric plans at the Detroit Auto Show. "The hybridization could actually help Wrangler," he said, noting it could improve torque distribution, a critical element for four-wheel drive vehicles." He added, "Electrification, absolutely. I could see Wrangler being a form of electric." The 2018 Wrangler goes on sale in January featuring a raft of improvements. It is about 200 pounds lighter thanks to the use of aluminum. There are also new engines, updated styling features and a nicer interior.
