I would be interested to learn more about the failing
over the lifetime of the car. Do these systems just give out
eventually?
On my BMW I had two speed sensors malfunction and the ABS
sensor blow out. Without the ABS, and with no ABS disconnect,
the brakes refused to function properly at any speed. Very
scary because until it was fixed there was no way to tell
when the car was going to stop. And with the speed sensors
(which are connected to the ABS and burn out about every
20-30k on 5-series cars) when they go you lose your speedo
and computer AND the ABS will shut down because it cannot
detect wheel spin.
On my ram I just had to replace all the brakes ($1100)
because the one time I needed ABS it failed and I ended up
cooking all four corners. Luckily I didn't jack knife the
trailer, but it was a costly lession to learn.
When TC becomes mandatory I'll just revert back to my old
jeeps and give up buying cars for good. It took me a long
time to find a mustang without all that crap attached.
