My CPS story...
Got the recall letter, did nothing about it.
Last weekend while driving about 300 miles from home the truck stalled but then caught on and kept running (doing about 70 on the highway).
Then in local traffic it stalled again, but restarted... got it to a dealership on Friday and asked them to do the recall. They asked if I wanted to spend $149.95 on diagnostics, just in case... I declined.
Picked the truck up Friday evening and 10 miles away it stalled. Restarted. Got to where I was going and on Saturday it would not start. Had it towed to the dealership.
They were open on Saturday and Sunday for service but were too busy to look at it. On Monday at about 3:30 I get a call that it's ready to go. I asked what the problem was, and they said the CPS they installed had failed.
When I got there to pick it up the repair order said "no problem found"!!! I questioned this and the service writer said the mechanic messed up and installed one of the old, recalled sensors instead of the new replacement and didn't put it down because he didn't want to get in trouble!
I wonder if he even changed it in the first place... afterall, why would Ford keep the recalled sensors in stock, and why would the parts guy give the mechanic one when performing the recall... sounds fishy to me...
