GM being sued over imploding Bosch fuel pumps in Duramax diesel trucks

Texas-based law firm Hilliard Martinez Gonzalez (HMG) this week filed a class-action lawsuit against General Motors over an alleged issue with Bosch CP4 fuel pumps. The suit claims Bosch designed the CP4 pump to work with European diesel fuel, which is thicker than U.S. diesel. When GM installed that pump in the 6.6-liter Duramax engine used from the 2011 to 2016 model years, the lawsuit claims the thinner U.S. fuel didn't provide enough lubrication, allowing air pockets to form in the fuel pump. That, in turn, allegedly let metal rub against metal inside the pump, causing the pump to eventually disintegrate and "send thousands of metal shards into the fuel injection system and every part of the engine." The Detroit News reported on the most recent lawsuit filed in Michigan's Eastern District Court, but the case is another piece of nationwide legal maneuvering going on since at least last September. Every U.S. truck maker used the Bosch CP4 fuel pump, and HMG originally went after all of them, as well as Bosch. On September 30, 2018, HMG filed a class-action suit in Texas on behalf of eight plaintiffs. The law firm wanted to prosecute the affair under RICO — the Racketeer Influenced and Corrupt Organizations Act — and named 10 defendants: FCA US LLC, FCA North America Holdings, LLC, F/K/A Chrysler Group, Fiat Chrysler Automobiles, N.V., Ford Motor Company, General Motors LLC, Robert Bosch GmbH, Robert Bosch LLC, VM North America, Inc., and VM Motori S.P.A.  The firm filed another suit in Florida on Nov. 2, 2018, against the same 10 defendants, again under the RICO statute, this time on behalf of more than 30 plaintiffs. We don't know how many other suits might have been filed, but the two suits mentioned apparently didn't have legs — the courts dismissed both quickly. So HMG shifted its strategy away from the RICO angle, and focused its efforts on GM, filing suit in California on Nov. 20, 2018. Instead of trying to catch 10 fish with a small net, HMG wants to score one fish with a big net. The results have borne more promise for the plaintiffs. In July this year, a judge in California denied GM's motion to dismiss, noting "the alleged defect is central to the vehicleÂ’s function." This latest suit filed on Aug. 6 in Detroit singles out GM again.  The Bosch CP4 is known to be problematic, however.

NHTSA investigating Ford's solution to May 2014 power steering recall

The National Highway Traffic Safety Administration is investigating a complaint that Ford's response to a May 2014 recall of the 2008 to 2011 Ford Escape and Mercury Mariner doesn't quite go far enough to solve a troubling power-steering problem. Roughly a year ago, Ford recalled nearly a million vehicles after it was found that a problem with the torque sensor's communication with the power steering control module could cut steering assistance for drivers. While manual steering would still be available, the problem was enough to ask drivers to report in to have the PSCM inspected, and if necessary, replaced (along with the torque sensor, or in dramatic cases, the entire steering column). That would only happen, though, if trouble codes were being thrown. If there weren't any problems, dealers were told to simply update the PSCM's software so that any issues between it and the torque sensor would simply throw a visual and audio warning – power steering would still be maintained. The petitioner claimed that following the recall work, he still experienced a problem with the torque sensor. According to NHTSA, a claim was made that Ford didn't go far enough in its solution to the problem, and that "the software update itself may in fact cause further issues with the affected vehicle's power steering, causing it to fail, and ultimately requiring replacement of the torque sensor or entire steering column." The petition was filed in early February and is now officially being looked into by NHTSA.

2020 Ford Super Duty Tremor vs. 2020 Ram 2500 Power Wagon: How they compare on paper

(Editor's Note: Due to inconsistencies in manufacturer reporting methods for ground clearance, an earlier version of this article stated the Ram Power Wagon's "ground clearance" to be 14.3 inches when in fact that is its "running clearance," which is deemed the ground to the lowest point of the truck MINUS the axles. The numbers below now reflect true ground clearance, or the ground to the lowest point of the truck, period. The chart and text have been updated to show both measurements for maximum accuracy and clarity.) For several years, the Ram 2500 Power Wagon has been the unquestioned king of heavy duty off-roaders. But competition is coming, and some of the strongest is from the 2020 Ford Super Duty Tremor. We decided to take a look at these trucks' specs and features to see how they compare in the realm of capability. The raw numbers are below along with some notes on each truck's unique features that go beyond the spec sheet. Off-road capability While both of these trucks boast impressive clambering abilities, each with particular strengths. The Super Duty Tremor earns points for better ground clearance and axle clearance, as well as approach angle. Some of the credit goes to the larger 35-inch tires and a shortened front air dam. On the other hand, the Power Wagon leads the Ford in departure angle, and in the ramp travel index. The latter is largely the result of the Power Wagon's electronically disconnecting sway bars, and for those unfamiliar, the ramp travel index measures articulation by having a truck drive one wheel up a ramp with the other on the ground. The farther the truck goes with the ground wheel in contact with the, well, ground, the better the score and the better the articulation. Numbers aren't everything, though. It's important to look at the equipment each truck offers, and things are closer, here, but the Ram still has an edge. Both feature off-road-friendly solid axles at both ends, but only the Power Wagon has fully locking differentials front and rear. The Tremor has a locking rear differential while the front is a limited-slip differential. The Power Wagon comes standard with a 12,000-pound integrated Warn winch, whereas such a winch is an option on the Tremor. The Tremor has its own unique features, though, including the 35-inch tires rather than the Ram's 33-inchers, and it has Ford's fancy off-road cruise control function called Trail Control. Both trucks have shocks and springs tuned for off-road use.
