Please help! 6/01/05 I had a loud screeching while driving to work, so I pulled into the dealer. Front pads are worn to sensor and need to be replaced along with the rotors. They noted rear wheel cylinders were leaking (I made them show me) and to replace. I also asked them to put a new battery into my key fob in which they told me they couldn't and had to replace with a new one (). I held off on the rotors/calipers. 6/02/05 - Returned because I was worried and had them replace rotors in front and rear calipers - 0 with 'free' rotors since they shouldnt be wearing so soon (14K). 6/07/05 - I notice all of a sudden that the car shakes badly especially around 60MPH. They balance and say it is fine. It is NOT fine, so I bring back 6/10/05 - they say they are unable to duplicate. I also told them I had the SES light go on a few months back but it went off when I replaced gas cap, but now it is back on and off sporadically and that the car has trouble starting every other day or so on the first try. The car codes found were: P0171, P0300, P0341 and P0656. Replaced fuel pump (0) and cleared codes. Told them that car has had rough idle pas few months, so they did a tune-up (0 - I didn't realize I had had one a year before). They say codes are cleared. 6/13/05 - Told them I still have shaking when driving especially around 60mph and that it did not happen before the rotors were changed on 6/2/05. They told me there were four flat spots and possible right front wheel is bent. Free oil change thrown in per my request. They also replaced the rotors with another pair when they duplicated vibration. 6/30/05 - SES light on AGAIN!!!!! Some of the same codes as before came up - P0300 and P0341 - I'm told I have to replace the ignition module per Dave the mechanic and Eddy the Service Assistant and that that should take care of the rough idle!! 0+ later and it still has a rough idle and I also noticed when accelerating, the car is rough as if it were a congested person, jerky in a way, lurches..... I also told them car goes into overheat range VERY easily and this concerns me as it never used to do that before. They checked temp sensor and temp gauge and for any leaks - all good. Also told them I'm hearing a squeaking and they can't replicate. 7/02/05 - Oh yes, I went out and got FOUR NEW TIRES due to Saturn telling me the shaking is probably caused by the flat spots and after being told my Avis guys that they looked bad - another 0+! The car still runs rough and when accelerating, still is rough and jerky and congested like. I even put premium gas in. I have paid roughly 00 on this car in the last month!!!
