Initially, I went in for an alternator and alternator belt. I were told it would be $309 plus $39 for a tow. They said that they would have to do a diagnostic to determine the actual problem. I ok'd it. The next day called me and told me my car was ready, BUT , they had to put in a new battery, replace two more belts, and the new price were $509. I paid the additional money. When they brought the car out of the repair area I got in and attempted to leave. The car wouldn't start. I raised the hood and saw that there were two belts just dangling on pulleys. Not even on. I went back in and told the clerk who serviced me,(Robert Calvario). He notified the mechanic who did the work and they took it back into the shop. The store was about to close, so he (Robert) told me he would call me tomorrow. they called. When I got there I were told that I needed a harmonic balance and a crankshaft pulley. Another $204. I asked them why didn't they say that in the first place when they did the diagnostic. They said that it didn't show up then. (yeah right). Reluctantly I went ahead and ok'd the work. the next day, again they called me to pick up the car. I paid the money and drove away. Again the car stopped on me at a red light. I called home and had my daughter to come and give me a jump and drove home. once home, i looked under the hood and to my shock, the serpentine belt was not on. I called Pep Boys again and were told to get the car towed back. I did. They finally put on the belt and told me they wouldn't charge me for it. (how nice, since I already paid for it), but they charged me $47 for the tow. After having the car home for a couple of days, the "check engine" light started coming on. That never happened before. I had to get jumps every time I tried to start up. Well, I didn't go back to Pep Boys. Instead, I took it to a neighborhood mechanic who did a diagnostic and said that I needed a crank position sensor, ignition coil, and if i wanted heat, a heater acuator. $550. I paid it. I've never had another problem again. I feel as if Pep Boys simply conned me out of $800 plus.
