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.

Ford updates Power Stroke diesel V8, strengthens F-450, tweaks King Ranch

Ford is giving its F-Series Super Duty trucks some upgrades for 2015, and we're happy to say that one of them is an improved Power Stroke diesel V8. Also, Ford is strengthening the top-of-the-line F-450 to handle more abuse. And if wild west-style luxury is your thing, the automaker has performed minor cosmetic updates to its King Ranch Edition trucks, as well.
The turbocharged 6.7-liter Power Stroke V8 is currently rated at 400 horsepower and 800 pound-feet of torque, and Ford only tells us the new and improved Power Stroke can "produce power beyond today's" engine. What, then, did Ford actually improve upon? First, the Blue Oval swapped in a new, larger turbocharger. The new Garrett GT37 turbine unit is 72.5 millimeters in diameter, eclipsing the old GT32's 64-mm diameter piece. Ford states output increases with the new turbo setup, but since the new turbocharger operates at a lower peak pressure than the old one, the automaker was able to eliminate the wastegate system and reduce the engine's complexity. Ford even redesigned the turbo's oil and cooling lines to make the powerplant simpler. A byproduct of the larger turbo is better engine exhaust braking, which is controlled manually by a button on the dashboard.
Ford claims the upgraded diesel engine is more powerful, more robust, more efficient and more refined than before.

Slew of Ford recalls affect more than a million vehicles

Ford is closing out September with the sad task of alerting owners to five different recalls, two of them camera related. The first is a safety compliance recall affecting 620,246 units of 12 models from the 2020 model year: Edge, Escape, Expedition, Explorer, F-150 and Super Duty, Mustang, Ranger, and Transit, plus the Lincoln Corsair, MKX, and Nautilus. On these vehicles, the circuit board in the rearview camera suffers from insufficient electrical conductivity. The issue can cause the resulting image to not appear or to be distorted, which can lead to an accident while reversing. Ford will begin notifying owners as of November 7 to get their vehicles to dealers for replacement of the rearview camera. The internal Ford reference for this recall is 20C19. The second camera-related issue affects the 2020 and 2021 Ford Explorer, Lincoln Corsair and Lincoln Aviator with the 360-degree camera. Technically, if you own a 2021 Explorer that only has a rearview camera and not a 360-degree camera, neither the above recall nor this one apply to you, but it's probably better safe than sorry here. There are 354,330 crossovers covered by this action. A video output issue could cause the displayed image to cut out, increasing the chances of a reversing accident. Ford will notify dealers starting October 7, the fix being to have a dealer update the Image Processing Module software. The NHTSA campaign number for this recall is 21V735, Ford’s internal reference number is 21S44.  The F-250 and F-350 Super Duty are in for another recalls thanks to potentially improper welds on the front axle's wheel end yoke. A bad weld could alter steering performance, getting the truck to pull left or right, or change the sensitivity of the steering. There are 9,628 affected trucks in the U.S. and 961 in Canada. Dealers will replace the axle assembly if any bad welds are found. Ford's reference number for this is 20S56. The fourth recall affects 38,005 Mustangs in the U.S. and another 2,873 Mustangs in Canada and Mexico from the 2020 model year. In this instance, the brake pedal bracket might fracture during sudden stopping, which can decrease brake pressure and increase the chances of an accident. Ford's internal reference for this recall is 20S52, the fix being to have a dealer replace the brake pedal bracket assembly. Finally, 126,033 units of the 2011 to 2013 Explorer are being recalled over a potential suspension issue.
