The U.S. transport safety regulator said on Thursday that it has launched an investigation into 1,732,000 Honda Motor vehicles over reports of instances of inadvertent braking that increase risk of a collision.
The probe comes a week after the agency said it was opening a formal investigation into 416,000 Tesla vehicles over complaints of unexpected brake activation tied to its driver assistance system Autopilot.
The National Highway Traffic Safety Administration said it has received a total of 278 complaints that allege braking incidents "occurring with nothing obstructing the vehicle's path of travel". Of the complaints, six allege a collision with minor injuries, it said.
The 2018-2019 model year Honda Accord and 2017-2019 model year Honda CR-V will be affected by the probe, the NHTSA said.
A preliminary evaluation is the first phase before NHTSA could issue a formal recall demand.
