Ignition Coils Failure Problems of Toyota Corolla

My car has 91,414 miles and has had multiple cylinder misfires with my normal daily commute of six miles each way. In three years on a 4 cylinder engine I have had three ignition coils replaced, twice within two and a half years and 10,468 miles on the #2 coil. All repairs have been completed by Toyota certified repair facilities with Toyota oem parts. This is not normal for a low mileage vehicle maintained with regular service.

I have a 2009 Toyota Corolla (le). I bought it almost exactly 3 years ago with about 12,300 miles on it. Currently, it does not have 50k. I have to drive downtown for nursing school, it takes roughly 20-30 minutes. The very terrifying and incredibly dangerous issue that I have been having is that I will be driving 65mph on the expressway and it will suddenly just drop down to 30/40mph. Due to this issue, I have almost been in a crash. I will change lanes thinking my car will accelerate to pass someone and it will just drop down to 30mph! also, while I am idle, it will shake and rev. . So the rpm will be up close to 2; yet, I am idle! I have read of others experiencing similar issues. This is so dangerous and I do not understand why this has not been addressed sooner. The worst part is no one knows what is wrong. I took it and had a diagnostic test run, it said one of the ignition coils was faulty. . On a 2009 Toyota with less than 50k miles. . . That doesn't sound, right huh. Well, I took it to a mechanic and they gave me a new battery, an oil change and ran another diagnostic test (after switching the ignition coil(b) to another (acord). It recorded nothing. I spent $500 it was fine for about an hour then the check engine light came back on and it started doing the same thing. I am very angry with Toyota for not addressing this issue, especially since others have experienced it and it is dangerous. My safety and the safety of others is at risk.

While I was driving the car started stalling really bad and losing power, the engine light came up and I couldn't speed more than twenty five miles, because the car started trying to shut off on me in the middle of the street again. I took the car to get checked out and the troubleshooting codes came out as being the ignition coils due to the engine harness being bad, (difficult to believe I said ), cables don't go bad like that in florida.
