The U.S. National Highway Traffic Safety Administration said on Tuesday, Nov. 6, that it was investigating whether General Motors Co.  (GM - Get Report) should recall an additional 1.7 million crossovers for windshield wiper failures.

GM recalled 367,000 2013 GMC Terrain and Chevrolet Equinox crossovers in the U.S. in August 2016 to address the problem, but the agency said it was probing whether the recall should be expanded to include another million-plus additional vehicles from the 2010-2016 model years after receiving 249 complaints about similar problems.

The Detroit Free Press first reported the news about the NHTSA investigation.

GM originally recalled the SUVs because warranty claims showed a higher-than-expected wiper failure rate. GM found that water and debris could get into the wiper assembly ball joints, leading to wear and eventual joint failure. No related crashes or injuries have been reported.

The company said it was monitoring other model years and will work with NHTSA on the probe.

Shares of GM were up 15 cents to $36.38 on Tuesday. The company's stock hit a 52-week high of $45.52 in June 2018.
