problem #3

Problem synopsis: While driving at freeway speeds (65 miles per hour) the vehicle lost power, causing the "reduced engine power" (rep) and "service vehicle soon" (svs) lights to illuminate. Upon pulling to the side of the road and shifting the vehicle into park, it would idle roughly until shutting the engine off. Vehicle would start immediately after, with high RPM at idle and hard shifts into gear. Vehicle would only exhibit these problems when the automatic transmission would shift gears, usually between 3rd and 4th gear. /// repair history: A repair shop diagnosed the problem as a failed engine control module, and a new one was installed into the vehicle. Cost of repair was approximately $1,100. Three months later (Oct. 2011), the vehicle started exhibiting the same problems. Returned to the same shop, and repairmen could not find problem, simply clearing the obd-II codes in the computer. Vehicle exhibited same symptoms once in November 2011 after a rain storm; no action was taken as vehicle did it only once. In December 2011, vehicle exhibited same problems four time during a 25-mile drive. Codes revealed P0606, P0700, P1811. Vehicle to be taken for a third time to repair shop to get this problem fixed.

I was driving my 2004 Saturn L300 at 55 mph. The car suddenly cut off. I was able to drift to the side of the road. I tried to restart the vehicle and it would not start. This has happened to me in a parking lot approximately 3 other times. I took the car to a mechanic and he said it may be the crankshaft position sensor. This could have caused a serious accident.

Multiple episodes of car not starting and stalling. Car actually lost all power and stopped running while I was driving. Cars were able to swerve around me and an accident was avoided. I am pursuing lemon law. Am very afraid to drive this car!
