Hyundai is adding about 420,000 more vehicles to its growing list of recalls to fix brakes, suspension and oil leak problems.

Hyundai, the world's fifth-largest car maker, announced three separate recalls on Friday concerning various issues with brakes, electric system and suspension in certain models. The total number of vehicles in the trio of recalls adds up to 420,000 vehicles, according to the documents published by the National Highway Traffic Safety Administration (NHTSA) on Friday, Auto News reports.

The biggest of three recalls posted by US safety regulators involve 225,000 Santa Fe SUVs from model year 2001 to 2006. According to the NHTSA, the affected models are from the "salt belt" states in the US because the road salt can corrode the front coil spring. The corroded suspension can make contact with the tire and cause a puncture, which increases the risk of a crash in a moving vehicle.

The safety regulators listed the 20 U.S. states where the cars are exposed to high risk of corrosion in the latest regional recall. The recall affects cars sold and used in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin as well as the District of Columbia.

The second safety recall affects 133,000 Hyundai Sonata mid-size sedans from model year 2009 to 2010. The car maker identified a leakage in the brake's hydraulic fluid that can increase the distance to stop the vehicle. Drivers can easily misjudge when to apply the brakes, increasing the risk of a crash.

Earlier this week, Hyundai recalled 883,000 Sonatas over faulty gear shift levers. With three new recalls, Hyundai's tally for the recalled vehicles rises to 1.3 million for the week.

Finally, Hyundai issued its third recall that covers 61,000 Veracruz crossovers from model year 2007 to 2012 due to an oil leak from the cylinder head. This may damage the alternator and the vehicle's charging system, resulting in a full loss of power and eventually a crash.

The car maker did not receive any reports of crashes or injuries. Car dealerships will inspect and repair the vehicles at no cost to the owners.
