Problem: 9/04/10
(Same as above)
When: 5:58PM September 4th, 2 days after getting the car back from Cabe.
Where: 405 South & 22 East & Euclid
Speed: 73MPH - 78MPH, and again while reversing at <5MPH
Situation: Traveling from Carson to Santa Ana at 5:58 PM on the 405 south in the carpool lane with one other passenger, a full tank of gas. Was traveling about 75MPH for 10-20 minutes, when the light turned on, I also have a video of this. Then merged onto the 22 East, and the light stayed on while varying down to speeds of 50 MPH. Exited Euclid expecting the light to turn off when we stopped at the light. We never fully stopped, and the light never turned off, perhaps we hit speeds as low as 5MPH. Then we turned left at a light after traveling 20-40MPH for 2-3 minutes, and while sitting stopped at the light for less than 60 seconds, the tire pressure light turned off. Then we pulled into a parking lot, and had to turn around, so I pulling into a corner, then put the car into reverse, and the tire pressure light came on again for less than 60 seconds, because it never went solid, and was only blinking.

5th Repair Attempt:
Miles in: 9,00X Miles out: ?
Hopefully this one works.
