2016 Scion Ia: check engine light

Filed Mar 2, 2020 · Engine · 126,000 miles · VA

The vehicle will intermittently shut itself off in the road for no apparent reason. The check engine light and battery light will display on the dash. However, when I put the car back in park and restart the engine there are no indicator lights on and no check engine light whatsoever. This car has been looked at by 3 certified toyota dealers and none of the mechanics can accurately pinpoint the issue. I am concerned this car will shut itself down in the middle of the highway and cause a collision. Worst experience with a car I've ever had. Surprisingly newer model vehicle and this difficult to diagnose. The car mainly sputters and stalls at idle or low speeds. We have tried numerous times to get an accurate diagnoses. Nothing left to do at this point except replace the car. I feels it is a danger to myself and others on the road.

Second time this happened...first they said battery...while driving, indicating warning lights on dash start blinking (ABS, check engine, traction, and others), then the engine goes into low hear and stays until the vehicle is turned off and back on. During these episodes the speed odometer is erratic. Also when in this state, the reverse gear does not engage. When this started it was a once a month problem, then weekly, now it happens daily/hourly. It started at approximately 40,000 miles. This happens while driving on city streets and highway, most of the time at stops and lower speeds but does happen on freeway too.

@ 9851 miles, picked up the car from an oil change (in nov. 2016.) noticed a light shaking when at a complete stop at stop light. The issue continued randomly, at first not very often, then started happening more and more often and became more and more intense at times. Car is at 18,029 miles (6/28/17,) and it still continues to randomly happen. Have taken the vehicle to the dealer several times, they do not know what's wrong with it, no service/engine lights or codes. The service manager and service advisor witnessed the problem in the service bay. I have been told it is "characteristic" of the vehicle (but didn't happen for the first 9851 miles,) and I have also been told I put "bad gas" in it (although it's been driven 8,358 miles since it started and there have been numerous types of gas from numerous gas stations put in the vehicle.) it still happens randomly, it doesn't matter if the AC is on or off, how long it been driven, the type of gas that is in it, or what the temperature is outside. Manufacturers rep could not "recreate" the intermittent problem, arbitrator said the 20 or so videos I recorded of things shaking in my vehicle when it does happen, was not "creditble evidence." I would like the issue I'm experiencing with my car to be posted on the nhsta website under problems, just in case other owners are experiencing the same issue.
