2014 Jeep Grand Cherokee probed by NHTSA for brake problems

Remember how Toyota got in all kinds of trouble over unintended acceleration? Well, the National Highway Traffic Safety Administration is investigating Jeep over unintended braking. NHTSA has announced a probe of 20,000 Grand Cherokee SUVs from model year 2014. Nine complaints have been received, with owners alleging that their Jeeps have issued brake warnings or gone ahead and applied the brakes when no threat was presented. Each complaint alleges that the vehicles have exhibited this behavior repeatedly, leading to a "sudden reduction in vehicle speed in traffic." So basically, a system designed to prevent accidents could actually increase the odds of a collision happening. Speaking to the Associated Press, Jeep spokesperson Eric Mayne said owners whose vehicles are exhibiting this behavior should report to dealers, while adding that the automatic braking/adaptive cruise control systems can be deactivated.

Date Investigation Opened: JUN 01, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15021 Component(s): FORWARD COLLISION AVOIDANCE Manufacturer: Chrysler (FCA US LLC) SUMMARY: The Office of Defects Investigation (ODI) has received nine complaints alleging inappropriate activations of the autonomous braking system in model year (MY) 2014 Jeep Grand Cherokee vehicles. All nine reports alleged unexpected braking incidents preceded by collision imminent brake warnings and resulting in sudden reduction in vehicle speed in traffic. Two complaints reported autonomous braking incidents with no objects on the road resulting in rapid increase in brake force and anti-lock braking system (ABS) activations. The complaints alleged experiencing multiple events at different locations and road conditions. A Preliminary Evaluation has been opened to assess the frequency, scope and consequences of the alleged defect. The following VOQ numbers are associated with the issues discussed in this resume: 10543837, 10713629, 10690650, 10663320, 10630362, 10596913, 10533622, 10533524, 10651269.

Federal investigations about safety of rear-mounted gas tanks is nothing new

The National Highway Traffic Safety Administration and Chrysler are currently making waves in our daily news feeds due to a disagreement over the safety of a few million Jeep Liberty and Grand Cherokee models. Specifically, NHTSA has asked Chrysler to recall the SUVs because of the location of their fuel tanks, but you may be interested to know that requests such as this are nothing new.
Besides the two Jeep models, NHTSA has launched investigations over the years in such models as the Ford Crown Victoria (and its police-car counterpart), GM pickups built between 1972 and 1987, and rather famously the Ford Pinto.
Understanding how automakers and NHTSA have dealt with fuel-tank-safety concerns in the past may offer a better understanding of how Chrysler and the government agency will settle their current dispute. Check out the complete article from The Detroit News here.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
