| Description of the problem | As i was driving home after work on friday around 2130, i was driving on the expressway about 65-70mph when i noticed that the car was declining in speed without me letting up on the gas pedal. I was in a fair amount of traffic with a semi behind me, i pressed down further on the gas pedal to try and increase speed while looking for a way to safely get off of the expressway. The car initially did not speed back up, after approximately 10-15 seconds, it sped back up. The car did this three times during my, normally 25 minute, drive home. This was extremely scary, especially being in heavy chicago traffic. I called the dealership first thing saturday morning and made an appointment to get it checked. The first available appointment was today, tuesday, and i had the vehicle there at 0700. The vehicle was scanned and pulled several codes: c1283, c1213, c1513, b1102, b112, c1334, c1335, c1126, c1662, c1312, c1314, and c1315. They then performed individual code diagnostics and traced code failures to yaw-rate sensor, brake pedal position sensor and evap purge solenoid. Estimated $1276. 97 + tax. |
