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.

Hennessey Mammoth 1000 6x6 TRX is prehistoric excess

A few things have changed on the way to the Hennessey Mammoth 1000 6x6 TRX, the six-wheeled pickup based on the 2021 Ram 1500 TRX announced in September 2020. Back then, it was going to be powered by the 7.0-liter Hellephant engine, tuned from a stock 1,000 horsepower to 1,200 hp, it would cost $500,000 before customization, and the Texas tuner said there'd only be three built — likely owing to the exceeding scarcity of that crate motor. The good news for folks who thought they'd be left in the cold is that a slightly different but still astonishingly massive Mammoth is going into serial production, and at a lower price. Instead of the Hellephant, a 6.2-liter Hellcat lives under the chest-height hood. In the Ram 1500 TRX the engine makes 702 hp and 650 lb-ft., but a 2.65-liter supercharger is the heart of a Lone Star State overhaul boosting output to 1,012 hp and 969 lb-ft. The rest sticks to the original formula. The lengthened frame stretches overall length to 283 inches, a skosh more than four feet longer than the donor truck — long enough to hold plywood and a picnic in the bed. A Bilstein suspension hangs all that sheetmetal seven feet high over 20-inch wheels wearing 37-inch Toyo Open Country rubber. If for some reason the six-toed contact patch doesn't get a driver out of trouble, the third axle can be locked up. In case of greater calamity, the stinger front bumper is ready to accept a winch, and the rear bumper sprouts a couple of attachment points. There are also footholds in that rear bumper to make rummaging in the bed easier, but those footholds are so high up they could use the same retractable steps alongside the cabin to reach. Naturally, the interior has been reworked, and there are a "dazzling array of LED lights." Hennessey says it will make 12 of these — the largest truck in the company's 30-year history — every year. The Mammoth 6x6 can be ordered directly from Texas or at any authorized Ram retailer for $449,950. We can't wait to see what happens when this meets the GMC Hummer EV pickup on the trail. If you like the idea of the Mammoth but this Mammoth is a tad too mammoth, consider the rest of Hennessey's family of Elephantidae, the four-wheeled Mammoth 900 and Mammoth 1000, or the Mammoth SUV.   Related video: This content is hosted by a third party.

Fiat Chrysler and Peugeot boards meet to finalize merger

MILAN/PARIS — The boards of Fiat Chrysler Automobiles and Peugeot will meet separately on Tuesday to discuss finalizing an initial agreement for a $50 billion merger to create the world's number four carmaker, sources said. A source close to FCA said the two companies could announce the signing of a binding memorandum early on Wednesday, followed by a conference call to explain further details later in the day. The two mid-sized carmakers announced plans six weeks ago for a tie-up to help them deal with big challenges in the industry, including a global demand downturn and the need to develop costly cleaner cars to meet looming anti-pollution rules. Ahead of the meetings, entities representing the Peugeot family, Etablissements Peugeot Freres (EPF) and FFP, unanimously approved a proposed memorandum of understanding for the planned merger, a source familiar with the situation said. FCA and PSA have said they would seek to finalize a deal by year-end to create a group with 8.7 million in annual vehicle sales. That would put it fourth globally behind Volkswagen, Toyota and the Renault-Nissan alliance. PSA's Carlos Tavares will be chief executive and FCA's John Elkann — the scion of Italy's Agnelli family, which controls FCA through their holding company Exor — chairman of the combined company. The group will include the Fiat, Jeep, Dodge, Ram, Chrysler, Alfa Romeo, Maserati, Peugeot, DS, Opel and Vauxhall brands, allowing it to serve mass and premium passenger car markets as well as those for trucks and light commercial vehicles.
