NHTSA closes book on Jeep 'trailer hitch' recall after all

After much debating and hand-wringing, the National Highway Traffic Safety Administration now says it has "no reservations" with Chrysler's plan to recall certain Jeep Liberty and Grand Cherokee models over concerns that their fuel tanks, which are located behind the rear axle, could rupture or leak in the event of a rear impact. The longstanding argument between the two entities saw Chrysler openly defy the Feds after a request to recall 2.7 million units back in June.
Chrysler's "voluntary campaign" will instead see it recall 1.56-million 1993-2004 model year Grand Cherokee SUVs, along with 2002-2007 Liberty models. Affected vehicles will get a trailer hitch installed free of charge, which Chrysler says will provide an additional degree of protection for the fuel tanks in the event of a crash. Jeeps with Mopar-branded hitches or hitches that were installed at the factory aren't affected by this recall.
Chrysler's argument throughout this battle has been that the Jeeps in question are no more susceptible to fires than comparable vehicles from the same time period, a position that NHTSA has seemingly arrived at as well. "Those vehicles performed at a rate similar to their peers. That is the keystone analysis as to whether something poses an unreasonable risk to safety," said outgoing NHTSA boss David Strickland during an interview with the The Associated Press.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000.

Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.
