Tesla faces investigation of suspension issues

DETROIT – The U.S. government is investigating Tesla Motors’ Model S sedan for potential problems with its suspension.

The National Highway Traffic Safety Administration says it’s seeking information from vehicle owners and from electric car-maker Tesla, which is based in Palo Alto, California.

People have posted multiple reports of possible Model S suspension failure on the agency’s website.

NHTSA said it’s also concerned that Tesla has asked owners to sign nondisclosure agreements about safety issues. The agency said such agreements could prevent owners from reporting problems to the government.

NHTSA said it was told by Tesla that the company didn’t intend to dissuade customers from reporting safety issues.

A message seeking comment was left with Tesla.

Tesla’s shares dropped 3 percent Thursday after the government released its statement.
