One analyst said General Motors may continue to recall vehicles well into the middle of summer.

WASHINGTON — US regulators are investigating potential flaws in at least 2 million General Motors vehicles that remain on the road, underlining the possibility for still more recalls on top of this year’s already-record tally.

The largest US automaker may continue to recall vehicles into the middle of the summer months, Brian Johnson, a Barclays analyst, wrote last week after meeting with a top GM executive. The company did not dispute Johnson’s characterization.

Clues to the sorts of issues that could be subject to recalls, and their potential scope, are contained in documents and data kept by the auto industry’s main US regulator, the National Highway Traffic Safety Administration. The agency is looking into complaints from drivers on issues including corroding brake lines and the unexpected failure of automatic braking and headlights in GM vehicles, according to data on its website, which is regularly updated.

Any recalls would come on top of almost 14 million vehicles that GM has called back so far this year in the United States. That already exceeds GM’s 10.7 million-vehicle mark set in 2004, according to NHTSA’s data. By comparison, Americans are expected to buy 16.1 million new cars and trucks this year, according to the average of analyst estimates compiled by Bloomberg.

GM is ‘‘continuing to work with NHTSA to resolve’’ its open investigations, Alan Adler, a spokesman for the automaker, wrote in an e-mail Tuesday.

In April, chief executive Mary Barra was called in front of Congress to explain why the company took years to publicize faulty ignition switches in models from the mid-2000s that have been linked to at least 13 deaths. Since then, GM has told owners of millions more vehicles to bring their cars to dealers for repairs to shift cables, seat belts, and other parts.

‘‘They let the genie out of the bottle and can’t put it back in,’’ said Jack Nerad, executive market analyst at auto researcher Kelley Blue Book. ‘‘They’re almost certainly going to be finding more.’’
