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.

2018 Jeep Wrangler four-cylinder fuel economy revealed

Fuel economy numbers for the 2018 Jeep Wrangler with the turbocharged 2.0-liter four-cylinder have finally been announced by the EPA. In the city, the two-door model gets 23 mpg, and the four-door Unlimited gets 22. Highway fuel economy for the two-door is 25 mpg and 24 for the four-door. Combined for the two-door and four-door is 24 and 22 respectively. These aren't Prius numbers, but they do make the four-cylinder Wrangler the most efficient version of the off-roader so far. The rest of the Wrangler range with V6 power gets 20 mpg combined, with the exception of the manual four-door, which gets 19. The most efficient V6 models in the city are the automatic models, which, regardless of length, get 18 mpg. On the highway, the best V6 is the manual two-door, which manages 25 mpg, and only loses 1 mpg in the city to the automatic. The question is, is the improved fuel economy worth the price premium of the four-cylinder? The automatic-only four-cylinder engine is an extra $1,000 over a V6 automatic, and $3,000 over a V6 manual. And when looking at the annual fuel cost estimates at fueleconomy.gov, you might only save $50 to $100 each year. The problem being that, while it's more efficient, it also demands premium fuel that the V6 doesn't. So it could be quite a while before the upfront cost is recouped. But if you want a Wrangler that's a little nicer to the planet, it's probably the way to go, plus you get an extra 35 pound-feet of torque over the V6, even if it means sacrificing nearly 20 horsepower.
