After getting gas, the vehicle will not start. It will crank and crank but not turn over, like it is starving for gas. Then after 10-15 minutes it will start barely and to keep it running I have to floor the accelerator. Any other time it starts just fine. There are also no codes causing a check engine light.

2017 Highlander with the Auto Start/Stop. It will sometimes go completely dead when idling, like at a stop light. Completely dead meaning zero electricity - no lights. This will last a couple of seconds. But one day, the car died at a stop light right. No power. Completely dead. Couldn’t turn on my hazard lights Gears were stuck. Couldn’t shift gears.

While accelerating onto highways, my Toyota Highlander suddenly misfires, causing rough engine and a natural response to decelerate instead of continuing to accelerate. The ignition coil was blamed, I replace and then a week later it happens again while trying to accelerate on the highway. Another replacement and then it happens again a third time. There was a known issue under Toyota’s TSB 0148-19, where engine computers were reprogrammed and all coils replaced. My vehicle…

While braked at a red light, my vehicle completely turned off. The engine would not restart, and all electrical panel light indicators did not come back on. I could not even turn on my hazards. The whole car was dead. After about a minute, I was able to restart the vehicle, but it took 5 attempts. I changed my battery two months ago, and just had my car checked by a mechanic and nothing was found to be the problem. No warning lamps or other messages were displayed. About 6…

I had my battery replaced about 3 days ago at the Toyota dealership . Yesterday, I was stopped at a red light and when I attempted to drive, the vehicle stalled. “Braking power low” message on the dashboard and the car would not restart. I was able to jump start it after about 30 minutes. I got towed to a local repair shop who could not identify or duplicate the issue. I had no warning indicators other than failing to start the morning of getting the battery replaced 3 days…

This is the SECOND incident with this vehicle in the past 4 months. When going to start my vehicle, it would not start. It gave me this error message: Braking power low, Stop in a Safe Place, See owners manual. There is NOTHING about this in the owners manual. The first time I thought it was battery related and after 3 different chargers on my vehicle, it finally started. Tonight I proceeded to push the button without the foot pedal and the radio came on, so it is definitely…
