2018 Jeep Wrangler Buying Guide | Answers to your SUV questions

There are few truly one-of-a-kind vehicles, but the Jeep Wrangler remains one of them. Available in traditional two-door form, or as the four-door Unlimited model, this proudly square-shaped SUV traces its origins back to the battlefields of World War II. While its shape seemingly hasn't changed much over the years, the 2018 Wrangler has been completely redesigned inside and out. A 3.6-liter Pentastar V6 and all-wheel drive are standard across the extensive Wrangler lineup, including rock-crawling versions like the highly regarded Rubicon model. While it doesn't have any direct rivals, some buyers might prefer an SUV with more refined ride and handling characteristics. The Wrangler's solid front and rear axles' primary purpose is off-road adventure, not on-road comfort, no matter how much it's been improved over its predecessor. Here you'll find all the information needed to make an educated buying decision if you're considering a 2018 Jeep Wrangler including safety and reliability ratings, engine specs, horsepower, fuel economy ratings and pricing. We'll also summarize what Autoblog's professional auto reviewers think of the Wrangler. Is the 2018 Jeep Wrangler Safe? The National Highway Traffic Safety Administration has not given the 2018 Jeep Wrangler an overall safety rating. However, the 2018 Wrangler is listed as scoring three out of five stars in frontal crash tests and rollover resistance. The Insurance Institute for Highway Safety, which provides ratings for new vehicles based on its own comprehensive crash tests, did not give the 2017 model year (previous generation) Wrangler, the last one fully-tested, a recommended rating. The 2017 Wrangler scored a "marginal" rating for driver side safety in the small overlap frontal crash test (a passenger side rating was not recorded). Side impact performance came in at a "poor" rating, as did overall headlight performance. One bright spot in an otherwise dismal safety score was the Wrangler's "good" rating in the moderate overlap front crash test. Ratings may differ for Wrangler models from other model years, so be sure to visit the https://www.nhtsa.gov/ NHTSA and http://www.iihs.org/iihs/ratingsIIHS websites to review ratings on the specific vehicle you're researching. At the time of this writing, the 2018 Wrangler is subject to one ongoing recall involving 106 vehicles.

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.
