My vehicle was backed into while ì was inside of it in a parking lot. Due to my horn failing., I was unable to alert the other driver to see me. The clock spring is what failed the first time at 95k they replaced it. I'm now at 147k and it failed again . Now I'm discovering that if it does not work, there's an electrical circuit failure and that the airbag will not deploy if I get in an accident. This is a serious safety issue and I feel Toyota should be responsible for it for the life of the vehicle . A horn should never go out. Especially if it not working will keep my air bag from functioning properly . 850 out of my pocket is way steep. The replacement part lasted half as long as the original part did when I bought the car that to me seems like a faulty part this should be obvious and they should just fix the problem cuz I might have to just consult an attorney should they choose not to. The attached photo shows what happens when you can't beep your horn at somebody who's about to back into your car !!! my car still has not turned on any kind of warning lamp for the airbag or any kind of malfunction light, no warnings on my radio. I have noticed that my Lane departure warning seems to work intermittently along with the automatic high beams that like to flash my high beams in people's face for some unapparent reason which also seems like a safety issue. If I had to take my car to an inspection station it would not pass an inspection due to the horn not working ! You cannot take your child to the Department of Motor Vehicles and let them take their drive test if your horn does not work ! which happened to be my case !! Very disappointing to say the least especially when you've paid $30,000 for a car.

after shortly pumping gas, I received a alert on my car that I needed to check my fuel cap, after checking fuel cap I proceeded to drive on the highway during this time a multitude of sensors started to go off on my car, and it started to drive weird there were light such as my interlock, being deactivated, parking, brake, deactivated, malfunction of VSC, collision deactivated. Then suddenly while driving at an accelerated speed, and trying to slow down, my engine turned itself off, and I was not able to re-crank my car. There is an active recall with Toyota for the fuel pump, which I was told by Toyota was the issue, but due to my VIN not being associated they would not repair as a recall
