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.

Chrysler recalling nearly 141k vehicles over electrical woes

Software glitches that randomly illuminate warning lights and cause instrument cluster blackouts are forcing Chrysler to recall 140,800 vehicles, The Detroit News reports. The automaker is recalling 132,000 2014 Jeep Grand Cherokees, 91,559 of which are in the US. In addition to the Jeep recalls, Chrysler is adding 10,800 2014 Ram 1500, 2500 and 3500 trucks to the list for similar problems.
Chrysler reportedly says, "Both events occurred infrequently and appeared to resolve themselves by tuning the vehicle's ignition off and then on."
Engineers discovered a problem with the anti-lock-braking system software that causes the instrument cluster display of the Grand Cherokee to illuminate warning lights and black out - even its ABS and electronic stability control systems are affected. To fix the Jeeps, Chrysler will update the vehicle's software.

Off-roading the Lyman Trail in the 2017 Jeep Grand Cherokee Trailhawk

Lyman Trail is in the backwoods of the Chelsea Proving Grounds in Chelsea, Mich. It's where FCA goes to push off-roaders to the limits. Autoblog's Greg Miglore made a recent visit to Lyman Trail with the 2017 Jeep Grand Cherokee Trailhawk. Check out the video to see how the SUV performed. Show full video transcript text [00:00:00] We are on Lyman Trail here, deep within the Chelsea proving grounds in the woods. This is where they test all the off-roaders, the Jeeps, the Rams, everything that's capable and needs some sort of a trail rating - this is where they bring it to shake it down. It's all downhill from here. Except when it's rocky and wet. Here we go! [00:00:30] Grand Cherokee Trailhawk is very capable off-road. Of course it's trail-rated. It definitely has all of the gizmos and things that you need to get over the obstacles that we're going to encounter. This first one is called traction. This is where, basically, to be trail-rated the vehicles need to have a certain degree of traction so they can basically, you know, stay sure-footed over certain obstacles. When going up things like this, pick your line, I'm going straight up the middle, and just stay nice and even. [00:10:00] Go straight up let the Jeep do the work, keep on going, skid plates doing their thing, there ya go. This one is over the riverbed. This simulates a dried riverbed. It's rocky, lots of stones here, things you might see on the shores of Lake Michigan. We're just gonna go right over it. Keep it nice and simple. Nice and easy. Okay, hit it kind of hard, gonna straighten the wheels. Again, you hear those skid plates, they are protecting the fuel tank, ... [00:01:30] the transfer case, and the front of the vehicle. So I'm not gonna touch the brakes, I just want to go over it nice and easy. We've come upon one of my favorite events here. This is where you go through the water. It's basically mud, a little bit of a bog kind of thing. Jeeps are so capable, you don't even have to worry about it.The trick about going through the water is to keep a nice even pace ... [00:02:00] and don't loose your nerve. Some people go in the water and are like "woah," freaking out because literally there's water all around you. So, just keep right on going, steer, point the vehicle right on through. We're making some waves here. Keep on going. Keep it smooth. Up the hill we go. And there you have it. Your Jeep not only went off-roading, it went off-landing. That's a bad joke.
