Regulators are investigating dozens of reports of braking ability in older Ford Edge SUVs.

The National Highway Traffic Safety Administration said it’s received 36 complaints of the problem in 2015 to 2017 Edges. 

Complainants say the braking loss happens during the act of braking without any advance indication, leading to increased stopping distance that could lead to collisions.

Some of the reports say they’d had the brakes repaired before the issue manifested, a portion of whom said the repairs were done in connection with a recall. NHTSA says in its preliminary investigation report, which indicates the problem stems from rear brake hose failure.

The federal agency’s probe aims to establish how many vehicles the issue involves.
