The vehicle has constant intermittent start up issues where you get a click when trying to start the car. This is very dangerous because of what if the car randomly cuts out while driving? the fact that they chanted the battery size has created concerns of potential fires with the vehicle as the faulty wiring mixed with a battery size that just a year later Hyundai changed could lead to a significant issue. There are thousands of complaints about this issue and the fact Hyundai is charging people hundreds of dollars for "fixes" that within hours of completion are rendered worthless is unacceptable. This issue is widely seen online for this year model but Hyundai refuses to acknowledge. Even spoke to a parts manager from Hyundai and they acknowledged the issue with this model in particular as it was the first of the new body style and that by the 2013 model they had made changes to the battery size and connectors which corrected the issue for future models.
