The totally integrated power module on left side of the engine compartment is not working. so ,the brake lights & horn do not work . however, the individual component was tested the brake lights & horn work individually. i don't know how long i have been driving like this but one of my co workers told me my brake lights were out because he almost hit me in the rear. this part is not covered under warranty because it is not part of the engine. it will cost apprx. $820 for repair. which i cannot afford at this time. i am reporting this because it is a safety issue driving without brake lights or a horn. someone can get seriously hurt or possibly die from driving like this. *tr
