DETROIT (AP) — U.S. auto safety regulators are investigating complaints that the automatic emergency braking systems on more than 1.7 million newer Hondas can stop the vehicles for no reason. The National Highway Traffic Safety Administration says it has 278 complaints that the problem can happen in 2017 through 2019 CR-Vs and 2018 and 2019 Accords. The agency announced the probe in documents posted Thursday on its website. In some cases the owners complained of unexpected speed reductions that could cause increased risk of rear collisions. In six cases, owners told the agency the problem caused collisions with minor injuries. Honda says it’s cooperating and that owners experiencing problems should contact a dealer.
