When reviewing the vehicle for purchase I noticed the SRS light on. I brought it to the dealerships attention. They instructed me to bring it back in the morning after signing paperwork so they could fix it. After I brought it back they let me know that they didn't see any SRS lights and would not be servicing the vehicle. There has been multiple mechanical issues with the vehicle including but not limited to the transmission going out, break recalls, engine leaks and now I'm being informed that my passenger air bag is deactivated. I just want a safe vehicle.

Car is extremely hard to turn/loss of power steering. Noticed that there was a recall on these vehicles but my vin was not included. Mechanic said Power steering rack is bad. This has been an ongoing issue with this car since purchased with only 70,000 miles - not sure why this VIN was not included in the recall? Car stock radio screen also has intermittent issues with displaying properly.
