I went out to start my car on Sunday afternoon to run errands but when I put my key in the ignition, I could not get the engine to start and didn't hear a clicking sound. The car had not been moved from the driveway for about a day. All of the lights, radio and dashboards work fine and are fully operational but I get nothing from the engine. . I had to take it to the dealership and they said it was a faulty electronic control module. The total cost of the repair is $1,200 and they are not even certain if it can be repaired.
The abs/esc and/or brake system warning lights came on. At various times the lights would illuminate and then would turn off after an ignition key cycle. (these are the exact problems that vw had with abs modules in earlier models. I am not positive if this is true but while doing research on those models, I read that these abs module issues typically came up after 105,000 to 110,0000 miles on the vehicle. My vehicle is just now with in that range) after taking it to a shop, the mechanic needed to replace the abs module, totaling around $1200. Note: date listed is an approximate date.
