June 1999

Vehicle stalls and dies on freeway almost causing wreck. Find out there is no fuel in tank even though fuel gauge reads 1/2. Toyota says TSB el010-00 addresses known defective 1999 and 2000 fuel gauges and also addresses some gauges inaccurately reading empty when 4 gallons remain, but my vehicle is a few months and miles out of warranty so toy will not pay for fix. No engine, no steering, no brakes, lots of traffic....
