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.

Jeep rear-mounted fuel tank controversy

Land Rover Defender V8 vs. Jeep Wrangler Rubicon 392 | V8 4x4s square off on paper

Land Rover pulled the sheet off its 2022 Defender on Wednesday, introducing another high-performance V8 to the off-road segment. This time, it's a 5.0-liter, supercharged V8 boasting 518 horsepower. It will be available in both the Defender 90 and 110 models. In the former, Land Rover says it can crack off a 0-60 run in just 4.9 seconds on its way to a top speed of 149 mph. The long-wheelbase 110 will be a bit slower, but "slow" probably isn't the right adjective to use here at all.  But Land Rover isn't the only automaker offering a high-performance variant of its off-road SUV. While Jeep may have been sneered at for presenting the 2021 Wrangler Rubicon 392 on the heels of the 2021 Ford Bronco's introduction, it starts to make a lot more sense in this context. There's reportedly a high-output Bronco on the way, too, so call Jeep the dinosaur of the group all you want, but you can't put a price on being first. Well, you can, actually, but that's not the point.  Thankfully, both Land Rover and Jeep have provided enough specs for us to rough out a comparison chart. Since the Rubicon 392 is offered only in four-door guise, we're looking at the long-wheelbase Defender 110 as its direct competitor here. Have a look: There are a few caveats to mention off the top. For starters, we don't have an official curb weight for the V8-powered Defender yet, as Land Rover has not finalized its U.S. specs. We used the European figures (as provided by a spokesperson), which we expect to be accurate within about 50 pounds. The 0-60 time provided by Land Rover was for the Defender 90, which is smaller and somewhat lighter than the 110. When equipped with the inline-6, the Defender 110 is about a tenth of a second slower to 60 than the Defender 90, so we figure it should be roughly the same for the V8.  While the Defender has nearly 50 horsepower on the Wrangler, that advantage disappears thanks to the Land Rover V8's monster weight penalty, which will fall somewhere between 600 and 700 pounds depending on equipment. Yikes. On the flip side, however, the Land Rover has the edge in top speed, and it's not even close. Chalk that up to the tires, we suspect. We know for a fact that the Rubicon 392's all-terrains dictate its speed limiter; Jeep's own engineers told us as much. This could make for a (hypothetically) interesting drag race, as the Jeep's advantage off the line may evaporate once triple digits come into play.
