(December 28, 2021) The National Highway Traffic Safety Administration (NHTSA) has stepped up its probe into engine fires that have plagued some Hyundai and Kia vehicles for more than six years. The NHTSA said it had opened an "engineering analysis" covering about 3 million vehicles to evaluate, among other things, the efficacy of recalls initiated by the two automakers. The agency added that it was aware of 161 fires occurring potentially due to engine failures.
