2006 Toyota Highlander Hybrid engine problems

We drove our 2006 toyota highlander hybrid home from town at about 7:00 p.m. On a cool evening, (six miles) 1/2 mile is a fairly steep hill to climb. On pulling into the driveway and stopping I noticed a burning smell and told my husband I thought the brakes were hot. After a couple minutes he noticed smoke coming from around the hood. He opened it and there were flames coming from the lower center area of the engine under the radiator hose. He got a fire extinguisher from the garage and extinguished the fire.

Tl* the contact owned a 2006 toyota highlander hybrid. The contact was driving approximately 10 MPH when the vehicle stalled without warning. The vehicle would not restart and was towed to an authorized dealer where the contact was told that the hybrid inverter would need to be replaced. The vehicle was not repaired. The failure mileage was 137,000 and the current mileage was unknown. The VIN was unavailable.
