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.

Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

Jeep Grand Wagoneer, Deserthawk and plug-in models coming soon

BOLOCCO, Italy — Today at FCA's Italian proving ground, Mike Manley rolled out the roadmap for Jeep's next five years. Manley has been in charge of Jeep since 2009 and has helped boost sales to more than 1.5 million units globally thanks to the success of models like the Cherokee, Grand Cherokee and Wrangler and submodels like the Trailhawk and Trackhawk. Well, there's more on the way, including new sand-prepped Deserthawk models, the return of the Wagoneer and Grand Wagoneer nameplates, and electrified versions of every model by 2021. While the plan for these next five years is a little less firm than the last one, it does provide the American automaker with some flexibility and breathing room. If you'll remember, by 2018 we were already supposed to have a new version of the Grand Cherokee as well as the premium Grand Wagoneer. Both of those are still coming, just not as soon as Jeep had hoped. Additionally, by 2022 Jeep plans to roll out two new three-row SUVs, new versions of the Renegade and Cherokee as well as the long-awaited Scrambler pickup. All in, Jeep plans to launch two models per year by 2022. That includes eight plug-in hybrids for the North American market. We saw one of the first Wrangler PHEVs at today's presentation. There are also plans to have a Level 3 autonomous vehicle on the market by 2021. Jeep will double down on its heritage, arguably one of the biggest things the brand has going for it. Its rugged image has helped boost sales in a market already clamoring for utility vehicles. By the end of 2018, FCA expects 1 in every 17 utility vehicles sold worldwide to wear a Jeep badge. The ratio should be even better for 2019. Related Video:
