Chrysler recalling nearly half a million Durangos and Grand Cherokees

Rule number one of public relations – save the bad news for Friday. Fiat Chrysler has adhered to that, announcing today that it'd be voluntarily recalling 467,480 SUVs. This latest recall could actually be thought of as a continuation of a September 2014 recall, relating to the fuel-cell relay. In that case, some 188,723 Dodge Durango and Jeep Grand Cherokee CUVs from model year 2011 were recalled. And this time, it's the Durango and GC in trouble again. FCA is adding crossovers from model years 2012 and 2013 to the fuel-pump recall, although only diesel-powered Jeeps with the 3.0-liter V6 that were sold outside of North America are affected this time around. As with the previous recall, deformities in the fuel-pump relay, which could affect its functioning. In most cases, FCA reports that the affected vehicles simply won't start, although they also could be prone to stalling. A new relay circuit will be installed that promises increase durability. Of the 467,480 vehicles being recalled, 338,216 were sold in the US market, 18,991 went to Canada and 10,829 were shipped south of the border, to Mexico. Outside of the NAFTA region, FCA is recalling 99,444 vehicles. No injuries or accidents have been associated with this recall. Statement: Fuel-Pump Relay February 27, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 467,480 SUVs worldwide to install new a relay circuit that improves fuel-pump relay durability. FCA US engineers have determined a condition identified in a previous investigation may extend to additional vehicles. The previous investigation, which led to a recall, traced a pattern of repairs to fuel-pump relays that are susceptible to deformation. This may affect fuel-pump function, preventing a vehicle from starting, or leading to engine stall. Of the two scenarios, the no-start condition is the more common. FCA US is unaware of any related injuries or accidents. The fuel-pump relay is located inside the Totally Integrated Power Module (TIPM), which also helps manage other vehicle functions. None of these other functions, including air-bag deployment, is affected by the fuel-pump relay. The new campaign affects an estimated 338,216 vehicles in the U.S.; 18,991 in Canada; 10,829 in Mexico and 99,444 outside the NAFTA region. Covered are model-year 2012 and 2013 Dodge Durango full-size SUVs and non-NAFTA 2011 Jeep Grand Cherokee mid-size SUVs equipped with 3.0-liter diesel engines.

Chrysler recalls small number of 2013-2014 cars and trucks over engine debris

Chrysler is recalling a small number cars over issues with their 2.4-liter four-cylinder engines. The recall, which affects 522 examples of its 2013 Dodge Avenger and Chrysler 200 models, as well as 2014 Jeep Compass and Patriot CUVs has to do with potential debris in the balance shaft bearings.
The abrasive stuff can cause the oil pressure to drop, which could lead to the engine stalling or outright failure. This situation could at best leave drivers stranded and at worst lead to a crash.
Chrysler will begin notifying owners, who will need to report in to have the balance shaft module replaced. All repairs are naturally free of charge. Scroll down for the bulletin from NHTSA.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
