I was on a gravel road yesterday and it was kind of bumpy just a scenery ride. Nothing major like obstacles or anything off road now i have this going on with my Jeep. Jeep is like it's holding back when starting off and then it lets up Any help would be greatly appreciated.

You have a bad wheel speed sensor.

A shop with an ABS code reader will be able to read the code to tell you which one. They are about $20 a piece, and can be changed at home. The fronts are a little more difficult than the rear. The rear are super easy, you don't even have to remove the wheel/tire. The rear tend to go out more often under normal driving conditions, especially dusty conditions as they are not in a sealed housing like the front. Dust and moisture gets on the sensor creating mud that keeps the sensor from being able to get speed readings from the ABS tone ring, and then the sensor goes bad.

Find a shop that can read the codes. The dealer will charge you an hours labor for the 5min job, so like $125. So call around. Once you know which is bad go to an auto parts store, get the sensor and change it out. All will be well again. Just had my rear passenger one go out. Super easy repair.


Happy Jeeping.

Thank you everyone. Everything I read and looked at came to the same conclusion of a wheel speed sensor. I just need to find a shop with a live data to be able to tell me which one it is that is bad !

Look at your brake light switch, it may have come loose or gone bad. It seems silly, but I had the same exact symptoms on my Audi last month and replacing the switch was the solution.

Everyone wanted like $150 to do it. ALSO 80 to put it on the computer and tell me which one was bad. However for $50 I bought 2 and did it myself. All is resolved now. Thank you everyone for your expert opinions and advice.
