Upon purchasing this vehicle in March of 2014 I have had numerous issues with it. One issue being it would not start. I let the dealer I bought it from look at it and he took it to a garage that he usually deals with and they told me they replaced the starter. However, I'm almost positive it had something to do with the ignition switch recall. Another issue is the horn randomly started going off in the driveway one day and now the horn does not work at all. The most concerning issue is that of the electrical problems I've been having with the car. The parking lights stay on, forcing me to have to disconnect the battery every time I leave the car for extended periods of time. The turning signals work intermittently, sometimes only after 7pm through 8am I won't even be able to get the signals to turn on. Other times they won't work if the windshield wipers are on.
