Got 2006 Kia Sedona inspected on Friday, hit with a bill for $745 to replace right front wheel bearing and a new batter because of problem with frequent non-start of van. Saturday morning, started van, backing out of driveway and ABS and ESC OFF lights come on and there is vibration and pulsating in brake upon pressing of brake pedal. Van back at mechanic on Monday in which they claim that right front wheel speed sensor was going bad, which was caused by old wheel bearing that went bad, causing the axle to be loose and rattle around causing the speed sensor to start to go bad, but would not have known it until the replacement of the wheel bearing made the right front tight causing the speed sensor to get readings kicking the ABS light on. Cost to replace this is $138. Get van home and immediately upon restarting, Check Engine Light comes on. So now what? Can anyone shed some light on this BS?

The ABS and ESC OFF lights did not come on until after the front right wheel bearing replacement. It was immediately upon starting my vehicle after it was returned from the repair shop. That is why I believe they did something that caused this. Any advice on handling this with the mechanic is very much appreciated. I have to call them again today because the Check Engine light came on, immediately upon the return of my van from them yesterday after checking the problem with the ABS and ESC OFF lights.

it sounds like they may have damaged the sensor during the operation. the sensor has to be removed to perform this operation.
is the code for the abs for the right front wheel??

I don't know what the code is, they did not put that down on the invoice, only the description that it is the "right front wheel speed sensor going bad".

from your description. I believe that something went wrong during the repair.
get a second opinion from another shop before you go back to them.

The battery is most likely a different issue to the other problems. A bad wheel bearing can definitely affect/damage an ABS wheel sensor but one would imagine the light would have been on prior to the repair. If a person is careless during the course of wheel bearing repair or let the ABS sensor harness support the weight of the suspension the sensor can easily be damaged. For illustration and repair instructions Kia as a car manufacturer put a lot of great technical information and work shop manuals on line for free for Kia owners. www.kiatechinfo.com

I am not disputing the battery replacement. I question the bad wheel bearing complete replacement because when I called in my appt. I asked the to check the driver left side because I was hearing a scraping upon making left hand turns. When the called to tell me I needed a right side wheel bearing, I questioned this because I had asked them to look into the left side. The response was, that is what they are telling me is wrong and needs replaced if you want to pass inspection. So, I had it replaced and now the problems have escalated with the needing a replacement of the wheel speed sensor. They disconnected my ABS because the told me they needed to until I replace the wheel speed sensor and this was perfectly safe. I drive two very young children around in this van. Are they correct that this safe?
