NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.

Ram 1500 TRX spied with remote-reservoir shocks and supercharger whine

The highly anticipated Ram 1500 TRX, Ram's Ford F-150 Raptor rival, has been spied again. And the big news is all in the suspension. Compared with the last prototype we saw, this truck sits much higher, and it now has fender flares to cover the wider track. It looks like some of the extra width may be from slightly bigger tires and higher offset wheels. But those might not be the only factors. Looking closely, the rear wheels have eight lug nuts versus six on the front. The previous prototype had six lugs on the rear. So this version may have a beefier rear axle, maybe from the Ram 2500. That axle may be a bit wider. The suspension itself is clearly farther along, too. Up front, there are some burly looking lower control arms. But in the back, any suspension reinforcements are long gone, and the axle seems to be supported by equally beefy trailing arms. Most exciting are what appear to be fancy remote reservoir off-road shocks tucked in the rear wheel arches. They're covered by little black sacks to hide them. The Rebel TRX concept from a few years ago featured internal-bypass shocks, and the Ford F-150 Raptor features the same kind of shocks. That Ram TRX concept also had 13 inches of suspension travel at each corner. Besides the updated suspension, we're pleased to report that the TRX is still rocking Hellcat power. Our spy photographer tells us that there's very audible supercharger whine. He also caught the truck on video, and it sounds gravelly and angry. We're very much looking forward to the truck's launch, which should be sometime before 2022.

Hennessey Mammoth is a Ram 1500 TRX turned three-row SUV

The 2021 Ram 1500 TRX is a thoroughly incredible machine that's great for pounding across dunes and flying over jumps, and you can even bring along some friends and their gear along for the ride. But what if you want to bring more friends along. Well, Hennessey Performance has the solution in the Mammoth SUV. What it is, is a TRX turned into a three-row SUV. It's something that Hennessey has experience with, as nearly a decade ago, it started converting some of its upgraded Ford F-150 Raptors (called VelociRaptors after being tuned) into custom SUVs. Like those Fords, the Mammoth will get a custom roof, rear pillars, glass and unified interior to provide more covered space. The company will also replace the second-row bench with captain's chairs and add a third row with a folding bench seat. While Hennessey could probably simply sell these TRX SUVs just with the body modification, the company will also add additional performance. An upgraded supercharger, pulleys, fuel injectors, engine calibration, intake and high-flow catalytic converters bring output to an absurd 1,012 horsepower and 969 pound-feet of torque. Hennessey claims it will get to 60 mph in 3.2 seconds and through the quarter-mile in 11.4. The company also raises the truck an extra 2.5 inches and fits a custom off-road bumper with LED lights and 20-inch wheels with 35-inch tires. The whole thing will cost $375,000. That's no small amount, but there's a lot of custom work in the vehicle. Plus, it's exclusive, with only 20 units slated to be produced. If it's what you're looking for, the company is taking orders now. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
