Default cruising range way off

Hey CL-

I've done a search, but nothing turns up. My wife's 04 RX330 was in the body shop for a month for a fender bender (daughter t-boned another vehicle- so the bumper cover, headlights, radiator support, and one of the fenders was replaced). When I picked up the car, it only had less than a mile cruising range. So I headed straight for the gas station. After filling it up, the cruising range only displayed 254 miles, which is wrong. A full tank cruising range is between 300-320 miles.

The data in the other INFO button functions:

(1) Driving time after engine start
(2) Average vehicle speed after engine start
(3) Average fuel consumption after refueling
(4) Instantaneous fuel consumption
(5) Driving distance after engine start

are correct

but the
(6) Driving range
data is about 50-70 miles off.

Could the month that the car wasn't driven done something to the cruising range? Does the RX computer reset after a couple fill-ups?

Any help would be great, thanks.

The body shop allowed it to sit and idle for a while, for whatever reason, killing the range estimate. Nothing more, nothing less. Or, possibly, after the accident, your daughter got out and left it running for a while, which happens. As long as it gets the gas mileage it usually gets, the estimate should improve for the next tank. The computer goes by what you got on the last tank.
