Going 40 mph the all lights on dashboard came on, the radio shut off, the abs brakes made a noise then everything on dashboard went out. Check engine light came on & the gas gage didn't work you couldn't tell how fast you were going ,the air conditioner quit & engine stopped, the vehicle was hard to steer & the brakes were manual & then engine started again. I turned the car off & turned it back on & the check engine light is on & the dashboard seems to work again. This has happened 2 times within 3 days. I am renting a vehicle cause I'm too afraid to drive the vehicle. There is a recall on this vehicle for the ignition switch with all the same vehicle loss of engine power, power steering & braking assist but it doesn't include the dashboard lights coming on & the dealers say it is not the same thing. The ignition switch recall came out in July 2014 & to date they have not provided any dealerships with the replacement parts. How can Jeep say it is not the same problem if they won't replace the recalled ignition switch to find out?.
