2012 JK issues.

[Purple Dixie]

I need some advise. I have a 2012 JK with some very frustrating issues, I have had it in the shop off and on all summer with no luck in fixing it. The e-brake light, the ABS light and the Traction control light will come on and the jeep dings. Now about 3 weeks ago doing 70 the speed odomitor dropped to below 40 then climbed back to 70, that happened twice in 30 min. Then 2 weeks later at Statewide the clock reset on Sat morning and again on Sun morning. So far the only thing done is "update the software". Is anyone else having the same issues?

Not sure if it pertains to jk's but when I added 35's to a 2008 Chevrolet with traction control I used a programmer to correct the speedo for tire height. If I was off on the actual tape measured reading for the tire by 1/4 inch the vehicle would trip the abs, parking brake light and traction control. Scared the hell out of me every time it went off too. It wouldn't be a stretch to say that maybe the abs system is not happy with tires? Hope that helps

The clock resetting is due to the wcm module, there is a tsb about that, the abs can be a number of things, is it lifted, bigger tires etc.....
