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.

2021 Ram 1500 TRX debuts as a Hellcat-powered, desert-running Raptor killer

The 2021 Ram 1500 TRX is here, and Ford’s free ride is over with the F-150 Raptor. Ford has had it good for a long time without any significant competition. Neither GM nor FCA entered the off-road full-size truck market with an offering like the Raptor. Chevy makes the Colorado ZR2, but itÂ’s a midsize truck. With the introduction of the Ram TRX, Ford finally has a proper competitor. Timing of the Ram TRXÂ’s release happens to fall in an in-between time for the Raptor, too. The F-150 is all new for 2021, but Ford hasnÂ’t released any details on the Raptor variant — though, weÂ’ve heard that the wait wonÂ’t be long. Regardless, Ford had better be aiming for the moon if it aims to best the TRX, because RamÂ’s new off-road truck is one hell of a moonshot. There is a lot to take in here, so weÂ’ve divided the chunks of information into a few digestible sections. LetÂ’s start with the underneath bits, which are arguably the most important of all when desert running and jumping is taken into consideration. Ram TRX frame and suspension Ram boasts that the frame underneath the TRX is 75 percent different from a regular Ram 1500. It uses thicker high-strength steel with low torsion attributes for stability and durability. The side rails are fully boxed, and sections of the frame are hydroformed. Ram claims its truck holds up to jumping and high impact events better than the competition, which in this case is simply code for the outgoing Raptor. ItÂ’s designed to handle rough terrain at 100 mph-plus. Compared to a Ram 1500 with the 5.7-liter V8, itÂ’s 600 pounds heavier. Ram is not messing around here. Damping is taken care of by Bilstein Black Hawk e2 adaptive shocks, aided by nitrogen-charged remote reservoirs to ensure maximum durability. The shocks will continuously adjust damping force to best handle the terrain, but you can control them via a number of modes, too. Ram says that in addition to the off-road capability, the shocks make for a smoother ride on pavement. The internals of the shocks feature a “Jounce Cut Off” that has three zones for progressive bottom-out control. You know, for when you take that jump at speed on your way to the office. 2021 Ram 1500 TRX chassis with brakes View 7 Photos Just like the other Ram 1500s, this one uses a five-link coil suspension design for the rear. However, the design is unique to the TRX with different hard points to allow room for a Dana 60 rear axle.

The 2019 Ram 1500 Classic is new but is also old

If you've been following the interesting strategy that Jeep employed by keeping the old Wrangler on sale alongside the brand new JL Wrangler ( at least until the Scrambler needed the production line), Ram's move here – slapping a "Classic" badge on the end of the old 1500 – shouldn't be all that surprising. And that's what's happening. Not all the trim levels will be available, and the move is targeted at fleet buyers and those on a tight budget. For those cost-conscious buyers, snagging a Classic rather than a new Ram might be a prudent move. After all, while the brand new Ram 1500 is a very nice truck and a decided upgrade from the old one, there's nothing fundamentally wrong with the outgoing truck – particularly if your needs are utilitarian. So, onto the changes. The reduced trim level spread on the 1500 Classic goes like so: Tradesman, Express, Big Horn (or Lone Star if you're in Texas), and SSV (Special Services Vehicle) intended for law enforcement. You'll notice that some trims are missing, and there's nothing fancy here. If you want anything beyond the Big Horn, like a Laramie, Rebel, Longhorn, or Limited, you'll need to step up to the newer truck. There's good news, though. Some stuff from the higher trims that are now out of production can be had on 1500 Classics through some new packages. The Chrome Plus package offers some upgrades to the Tradesman trim, like body-color bumpers, 17-inch wheels, keyless entry, and carpet. The Tradesman SXT gets chrome bumpers, fog lamps, dual exhaust (on V8 models), and 20-inch chrome wheels – some of which is new to the Tradesman trim, even as an option. And the Express Black Accent Package blacks out the badges wheels, and headlight bezels. So while there's less choice overall, you can still add some up-level touches to the 1500 Classic. The powertrain and bed/cab configurations are still robust. You can get the Regular Cab with a regular or long bed, the Quad Cab with the regular bed, or the Crew Cab with the short or regular bed. The 3.6L Pentastar V6 and 5.7 Hemi V8 are both available with 2- or 4WD, and the EcoDiesel will go on sale later. We don't have the all-important pricing information to tell you how good of a deal the Ram 1500 Classic will be, but buyers dragging their feet on buying a lower-trim 2019 Ram 1500 might want to cool their heels until later this year when the 1500 Classic goes on sale to see if it better fits their needs.
