ABS light and "Service Elec Brake System" and gas mileage gone to 6mpg
 
This all started after I got the tires replaced... and of course the shop says they did nothing that could have caused it...
I am getting an erratic ABS light with the message "Service Elec Brake System" and the gas mileage goes to crap. When the lights come on the jeep feels like I have to force it to move and when I take my foot off the gas it slows down quicker than normal. I cant figure out if it is the brakes or the tranny downshifting or not shifting????:confused: I did get a WSS code for the right rear but it cleared after I cleaned it.. figured they got brake dust on it when they replaced the tires. I am STUPMED:confused::confused::confused:

I was wrong... mine is also the left rear sensor... I am going to replace it and see if it fixes the issue. Thanks

Hey guys I started to get this exact thing with my 05 Grand Cherokee. But in addition I also get all my interior dash lights and such all light up at once and flash and then stop for a bit. The dash lights flicker out too then come back.

the ABS light and service elec brake system came up on my wifes 05 2 days ago (she neglected to tell me) and this morning the left rear brake is locking up. I tried to go from a stop and the it locked and I had to drag the wheel around the corner to a parking spot. the traction control light is also on and I'm getting a service 4 wheel drive system warning.

Any ideas?
