My Toyota Highlander would not go into park. The SUV lunged forward over curbing and into building. Then went violently into reverse and into a uncontrollable spin. Then the SUV went violently into drive and jumping over a curbing and into a ditch and was sitting on top of a natural gas line. During this whole time I was pressing the brake and pushing the ignition switch trying to turn off the engine. This was done in a parking lot as I was trying to park.

problem #4

Highlander

  • 27,800 miles
I was driving on an interstate with dynamic speed control on. The car slowed appropriately to match the speed of the the vehicle ahead of me. Suddenly several warning lights and messages appeared: Master warning light, check engine, check AWD, go to Toyota dealer, engine power loss.the car slowed to about 35 miles an hour (in a 65 mph area) while traffic in front of me was at (or above) the speed limit. I was able to safely get to the shoulder and turn the car off. I took a few minutes to use my smartphone to find the nearest dealer and planned to go off the exit (which was just a few yard ahead) and try to make it to the dealer on side roads. When I restarted the car all lights and warnings were off and the car drove without incident until I reached the dealer near my residence, about 100 miles away. The service rep at the dealer advised I had traveled too far since the incident for their computer analysis to work and he had no advice except to go to the nearest dealer if it ever happened again. I would like to have some info on how to avoid such an incident again.

While driving on interstate on cruise control at 75 mph, without warning, alerts went off and vehicle slowed to about 40 mph and would not let me go any faster. The AWD failure alert sign came on as did system engine failure alert came on. I was able drive at that slow speed for approximately 4 miles on interstate ramp with flashers on. My son advised me to turn engine off for one minute and restart, which it did without alerts. Then able to drive the 2O miles home. Next day took it dealership where it's been going on 3 rd day. Extremely bad possible outcome could have occurred on the interstate being rear-ended or if had been trying to pass someone or vice verse. Car presently at dealership so do not have VIN. Or actual mules

Driving approximately 72 mph when vehicle died causing a potentially very hazardous situation - check engine light came on, master warning light came on, see dealer for repair message displayed. Was able to limp to side of road and had vehicle towed to dealership. After 2 days of diagnostic testing the engine control module (ECM) was replaced under warranty (less than 12,000 miles on vehicle). The vehicle is running, however, now notice a decrease in gas mileage and difference in transmission shifting since replacement.
