Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 2 tested variants for this model year.
For the 2017 Jeep Wrangler, the heaviest concentration of complaints centers on the braking system and engine. On the brake side, owners frequently report ABS control module failures, with many describing warning lights for ABS, traction control, and stability control illuminating and staying on, leaving those systems non-functional. A recurring frustration is that replacement modules have been on extended backorder, sometimes exceeding a year, leaving owners unable to get the vehicle repaired. Wheel speed sensor failures also come up as a related pattern, with some owners noting the ABS and cruise control dropping out together. On the engine side, owners report oil drain plug failures, the plug reportedly becomes brittle and cracks, causing sudden oil loss and in some cases complete engine failure at relatively low mileage. Powertrain complaints round out the top three reported systems, though brake and engine issues clearly dominate the complaint set for this model year.

By System
The 2017 Jeep Wrangler has 6 recalls, the most serious involving the fuel tank control valve, which can leak fuel during a rollover, allow the tank to be overfilled, or let debris enter the fuel system, raising the risk of fire.
On the electrical side, a wiring fault under the hood can cause the engine to stall unexpectedly. The brake light switch can also malfunction, either keeping the brake lights on continuously or allowing the transmission to be shifted out of Park without pressing the brake pedal. Both conditions raise the risk of a crash.
Two recalls affect occupant protection. In a crash, the front impact sensor wiring can pull free before sending a signal to the restraint controller, preventing the front airbags and seatbelt pretensioners from deploying. On right-hand-drive models only, the driver's seatbelt buckle mounting strap can fracture and separate from the seat frame, leaving the belt unusable in a crash.
