This is an ongoing saga that started out simply enough - just needing new struts. From my previous post at the end of August:
"We had a shop install new rear struts, tops and springs plus new front struts, bearing plates and sway bar links. When they were done the 3 warning lights ("vsc", "vsc off" and "ABS") are on all the time. The traction control switch under the dash has no effect. The shop claims that they tested for codes twice and there are none. What did they do? They are talking about a short or bad cable or bad computer that is going to above and beyond the original estimate for the strut replacement - I don't think so "
...and
"Just got back from another visit to the same shop and they say now that they were able to find some codes in the system: 34, left rear wheel speed sensor, open circuit ..and.. 43, deceleration sensor, out of calibration. They say it needs a new left rear wheel speed sensor and then recalibrate the yaw sensor for $375, and that "there is no way their technician caused this" - "it has probably been going bad for a long time and when they moved it (the cable, or the sensor itself?) to remove the wheel it shorted out". Another $91 to diagnose the issue. "
I didn't believe them and I didn't want them working on the car anymore (especially since they fully intend to charge for everything) so a few weeks ago I took it to the local Toyota dealer. They verified the code for a bad wheel speed sensor and replaced it, which fixed the problem for another $300. They said the same thing that I have heard from this forum and other searches on the subject, that it is very likely the tech screwed up the sensor while changing the struts.
So we drive it for about 2 weeks and then hit an average bump on the highway and all 3 lights come on again, same as before except now you hit a bump and they come on, hit another and they go off. ONLY at highway speeds. Take it back to the Toyota dealer, same code. The said the sensor had debris on it, cleaned it off. On the way home, it does it again. Take it back a 3rd time - now they say we have a bad "ABS tone ring" which can only be purchased as part of the wheel bearing and hub assy. Now they want another $650 Remember that the lights now only 'cycle' on or off at highway speeds, when hitting a bump. If they are on when you shut off the car, they will be off when you start it again until you reach 65-70 mph and hit a bump.
I feel like I am getting hosed for technician incompetence. Any advice, thoughts?
