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.

Best-selling vehicles by state

America loves trucks. According to Edmunds, which has tracked the best-selling vehicles by state based on new vehicle registrations, 40 out of 50 U.S. states’ best-selling vehicle is a pickup. Most often, thatÂ’s the Ford F-Series, but occasional Chevy, Ram and even Toyota top the lists. Here, weÂ’ve compiled the best-selling vehicles by state, including the four runners-up for each state. Interestingly enough, only one EV shows up in a stateÂ’s top five (Tesla Model 3 in California). Read on below to see whatÂ’s most popular in your state.

Road tripping in a Ford Fusion Energi PHEV

Following my earlier Chevy Cruze Diesel trip and recent press-launch drives of Volvo XC90 and Hyundai Sonata plug-in hybrids, an opportunity arose for another road trip. I wanted to do it in a plug-in hybrid, primarily to learn whether its higher price vs. gas-powered and conventional hybrid versions of the same vehicle – is justified by its capability to operate as an EV, burning no fuel at all with its engine off, at least for short distances. I've been skeptical of plug-in parallel hybrids. As I've written before, I've been skeptical of plug-in parallel hybrids because they are generally good for very limited electric miles (typically 10-15, depending on driving style, terrain, and temperature) at fairly leisurely speeds before their engines kick in. But I've recently spent time in two new examples – the 2016 Volvo XC90 T8 and the 2016 Hyundai Sonata PHEV – that offer more EV range, mostly because they tote bigger (thus more expensive) batteries. Both promise 24-25 miles of battery-only range, and the latter can recharge on the fly. Unfortunately, neither was yet available for my July road trip, nor was a Honda or Toyota plug-in, but Ford anted up a Fusion Energi borrowed from its Marketing department. "The state-of-the-art lithium-ion battery and electric motor combined with the gasoline engine offers maximum efficiency," says Ford about it. "This strategy offers the best of both worlds, providing the 2016 Ford Fusion Energi the capability to be driven as an electric vehicle for short trips and as a hybrid for longer trips." I've been a fan of Ford's Fusion since the first-generation debuted a decade back, and the handsome Gen II version launched for 2013 has been Detroit's best answer to the Honda Accord/Toyota Camry/Nissan Altima Japanese juggernaut in the popular US mid-size sedan segment. Beyond its leading-man looks, it offers an array of highly-functional features (some exclusive), a choice of three gas engines (a base 2.5-liter four and 1.6-liter and 2.0-liter direct-injected, turbocharged EcoBoost fours) and both parallel and plug-in parallel hybrid versions. The regular hybrid originally boasted 47 mpg before Ford adjusted it to be more realistic. The gas engines drive through a 6-speed automatic transmission (a 6-speed manual is standard with the 1.6-liter EcoBoost), the hybrids through an electric continuously variable transaxle (eCVT), and all-wheel drive is available with the 2.0-liter EcoBoost four.
