“While coming to a stop at a stoplight, a car come out if no where. I tried to slam on the brake to come to a stop faster but the breaking system did not react to the pedal being pressed down. I was met with a stiff pedal and I could feel the brakes pushing back which caused me to hit another car that had already entered into an intersection.”

NHTSA complaint #11186148, filed 2019-03, 2 miles“Was driving my car home from work and about 5 minutes after I started it and began to drive, I went over a speed bump going 5mph and suddenly my theft alarm system starts going off and incessantly honking.

They said it is an electrical issue, but not a Toyota one. …”
