Recalls for the 2003 Hyundai Sonata: 6
Repeated use of the interior door handle may cause wear of the chrome plating. If the top edge of the handle has very thin chrome plating that portion of the plating may wear away more easily than more thickly plated areas as the door handle is used. A sharp edge could lacerate or otherwise injure a vehicle occupant.
Repeated use of the interior door handle may cause wear of the chrome plate. If the top edge of the handle has very thin chrome plating, that portion of the plating may wear away more easily than more thickly plated areas as the door handle is used. This may inflict laceration injuries to anyone using the door handle.
Road salt applied in these jurisdictions during the winter months may result in progressive, internal corrosion of the front sub-frame on the vehicles, and may result in thinning or perforation of the sub-frame steel. If that happens, the vehicle may lose drive power to the wheels, and the front wheel may make contact with the fender or wheel well, thereby increasing the risk of a crash.
Certain passenger vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 301, "Fuel system integrity" A valve on the fuel tank assembly may not close properly. If a vehicle rolls over and the fuel tank assembly valve is not properly closed, fuel spillage may occur. Fuel spillage in the presence of an ignition source may result in a fire.
Some passenger vehicles contain a fuel tank assembly valve that may not close properly. If a vehicle with a fuel tank assembly valve that is not properly closed were to roll over, fuel spillage may occur. Fuel spillage in the presence of an ignition source may result in a fire.
On certain passenger vehicles equipped with a traction control system (TCS), if the T125/70D-15 compact spare tire is installed on a front wheel position, the TCS may inadvertently activate beginning at speeds of 20 mph. Inadvertent activation of the TCS will cause automatic application of the brake at the wheel where the compact spare tire is installed.
