When consumers entered their vehicle identification number to determine whether their automobile was subject to recall, some were erroneously told no, according to a statement issued by the National Highway Traffic Safety Administration Friday. An error caused that message for vehicles where recalls existed and parts weren’t available.

NHTSA told consumers to check the GM website after 5:30 p.m. New York time Friday for accurate information. GM said in a statement that the company was making necessary changes to the site and that those with questions should call customer service.

The largest U.S. automaker has recalled nearly 29 million vehicles in North America in 2014, breaking a single-year record for most recalled cars in the U.S. The Detroit-based company has stepped up the pace of recalls as it faces multiple investigations for its slowness in calling back 2.59 million small cars with ignition flaws linked to at least 13 deaths.
