Car broke down at a light on my way to work on Friday June 6. It would not start back up. Car was towed to the nearest Hyundai dealer. They said the car over heated. Repairs were made and car was given back to me on June 11 or 12. Check engine light came on less than an hour after picking up the car. Dealer was closed so called them the next day and took it back. Dealer kept it another day or two to check everything out made some minor repair and gave it back. On Saturday June 21, the car over heated again at an out of town location.
On 11/26/07 the car got overheated, engine check light came on and engine shut down on the highway, coolant leaked out, car towed in. Bridgeport key Hyundai replaced coolant temperature sensor on 04/11/08 the car stalled on the highway without engine light coming on, coolant leaked out, engine failure caused a collision with another vehicle from the back. The car was towed in, it needs engine replacement. We believe the coolant repairs to be defective. Dealer denies our claim and blames engine failure on poor maintenance. I have read a number of reports about Hyundai engine stalling/coolant leak. In addition abs/tcs light has been coming on with the brake pedal vibrating and making noise. Car wouldn't stop as requested especially on wet, icy surface. Dealer cannot locate the problem please investigate both defects.
