One Factor Bringing Fiat Chrysler (FCAU) Stock Down Today

NEW YORK (TheStreet) -- Shares of Fiat Chrysler (FCAU) were falling 3% to $15.60 Friday following a report that U.S. federal regulators are probing complaints that automatic braking systems in Jeep Grand Cherokee vehicles can unexpectedly activate.

The U.S. National Highway Traffic Safety Administration said it received nine complaints from drivers about the autonomous feature that's available in about 20,000 vehicles in the 2014 model year, according to the Wall Street Journal.

The government agency opened the preliminary evaluation on the issue on June 1. The evaluation is the first step the regulators take when scrutinizing potential defects, according to the Journal. The probe could lead to a recall, the many probes often result in no action.

About 8.2 million shares of Fiat Chrysler were traded by 12:13 p.m. Friday, above the company's average trading volume of about 5.5 million shares a day.
