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.

GM says it favors fuel-efficiency rules based on historic rates

WASHINGTON — General Motors backs an annual increase in fuel-efficiency standards based on "historic rates" rather than tough Obama era rules or a Trump administration proposal that would freeze requirements, according to a federal filing made public on Monday. The largest U.S. automaker said the Obama rules that aimed to hike fleet fuel efficiency to more than 50 miles per gallon by 2025 are "not technologically feasible or economically practicable." The Detroit automaker said that since 1980, the motor vehicle fleet has improved fuel efficiency at an average rate of 1 percent a year. Fiat Chrysler Automobiles NV said in separate comments that the auto industry is complying with existing fuel efficiency requirements by using credits from prior model years. As a result, even if requirements are frozen at 2020 levels, "the industry would need to continue to improve fuel economy" as credits expire, it added, warning if the government hikes standards beyond 2020 requirements "the situation worsens ... without some significant form of offset or flexibility." Fiat Chrysler and Ford urged the government to reclassify two-wheel drive SUVs as light trucks, which face less stringent requirements than cars. A four-wheel drive version of the same SUV is considered a light truck. Ford backs fuel rules "that increase year-over-year with additional flexibility to help us provide more affordable options for our customers." GM's comments said it was "troubled" that President Donald Trump's administration wants to phase out incentives for electric vehicles. The Trump plan's preferred alternative freezes standards at 2020 levels through 2026 and hikes U.S. oil consumption by about 500,000 barrels per day in the 2030s but reduces automakers' collective regulatory costs by more than $300 billion. It would bar California from requiring automakers to sell a rising number of electric vehicles or setting state emissions rules. The administration of former President Obama had adopted rules, effective in 2021, calling for an annual increase of 4.4 percent in fuel-efficiency requirements from 2022 through 2025. GM has been lobbying Congress to lift the existing cap on electric vehicles eligible for a $7,500 tax credit. The credit phases out over a 12-month period after an individual automaker hits 200,000 electric vehicles sold, and GM is close to that point.

Ford Mustang GT350R adds a lot more than just a new letter [w/videos]

Okay Chevrolet, the ball is in your court. Ford served up one hell of a rebuttal to the track-focused Camaro Z/28, introducing the limited-production Mustang GT350R, complete with over 500 horsepower, over 400 pound-feet of torque and freaking carbon-fiber wheels. Carbon-fiber wheels. Seriously. It's because of those 19-inch hoops, along with some other changes, that Ford was able to slice 130 pounds from the already lightweight GT350 Track Pack. The wheels are responsible for a 13-pound reduction in unsprung weight per corner, while the removal of such superfluous things like the air conditioning, stereo, rear seats, trunk carpet, backup camera and tire inflator accounts for the rest of the weight reduction. Along with the lower weight, Ford has thoroughly reworked the GT350's aerodynamics, adding a simply monstrous rear wing and diffuser, along with vented wheel wells, a new hood vent that both extracts heat and reduces lift. Beside the aero aids, Ford has shod the carbon-fiber wheels in ultra-grippy Michelin Pilot Sport Cup 2 tires, just to guarantee the shiny side remains up. View 21 Photos Ford retained the standard GT350's 5.2-liter, flat-pane V8, Torsen limited-slip differential (complete with a 3.73 rear axle ratio), although as power figures haven't been published for the standard car, there's no way to know whether the GT350R received a power bump. What we do know, though, is that the GT350R will not be limited to the track. While that's certainly its natural habitat, owners will be able to register and drive this monster on public roads. Take a look at the official press release on the GT350R, available below. And also be sure to have a peek at both Ford's stock photos of the new car, as well as our full gallery of live images, direct from the Blue Oval's Detroit Auto Show press conference home at Joe Louis Arena.
