I bought a new car. 3 1/2 months later, I was rear-ended. I took car to dealership to get tailgate and pan and bumper repaired. When we picked up vehicle, strong toxic fumes from repair were so strong that we could not drive car. Instant headache, upper respiratory aggravation, sore throat, burning eyes. Car has been to repair shop numerous times and months later still causes illness in family. At one time that I drove car I almost lost consciousness. I have informed Hyundai dealership several times. I informed Hyundai corporation. Problem persists consistently for 8-9 months and after numerous trips to dealership. The dog foams and vomits before car starts moving.

Brand new car- a few days after purchasing and driving the car, noticed car was not driving right. Several symptoms became noticeable. Car would jerk when accelerating and braking. Cars pick up was delayed and had a very uncomfortable vibration, while in idle and while driving, to the point of getting nauseous while driving in the car. Took car to Hyundai service and told them of symptoms and my concerns of something not right with the car. The mechanics felt the problems I explained above and said something was wrong, now had to figure out what exactly. Several tests were done on the car but nothing showed up on electrical grid. Service had to call a higher tech out in California to see what to do next. California tech made them run several tests, all this took more then 2 weeks until they finally figured out that the engines throttle assy was defective and not functioning properly. They said that this also caused the sensor to malfunction. They replaced the throttle assy and claim the car is repaired. No longer trust car is safe to drive due to the electrical and engine defects that where found after the original inspections by the manufacture and the dealership failed to find these defects with the car and sold it.

The contact owns a 2012 Hyundai Tucson. The contact stated that the vehicle would not start, even after the fuel tank was filled to capacity. She had to apply pressure to the brake and accelerator pedals in order to start the vehicle. The dealer made three attempts to duplicate the failure. The manufacturer had not been notified nor was the vehicle repaired. The current mileage was 1,304. The approximate failure was 1,000.
