Are there any car mechanics that can actually fix a problem without creating another?(1) I brought my car in for the A/C to be recharged and it came back with the fan rattling. (Santa Fe Auto, Santa Ana) (2) I brought my car in for a new battery and it came back with a sporadic humming after my radio plays for awhile. (Santiago Hills Car Care, Orange) and now the latest snafu (3) I bring the car in for a new alternator and it comes back without my car lights flashing when I unlock my door or any beeping sound when I lock the door. (Rollings Automotive, Fullerton) Three different car shops and all three my car comes back with problems it didn't have when it when in. I am so tired of this.
