SAN FRANCISCO — Lawyers for Tesla Motors Inc. are seeking sanctions against two plaintiffs firms after a federal judge found a securities lawsuit they filed against the luxury car company “utterly failed” to plead an actionable claim.

The plaintiffs lawyers with Pomerantz and Glancy Binkow & Goldberg accused Tesla of making false statements about the risk of fire posed by batteries in the company’s electric cars. In a motion filed Thursday in the Northern District of California, Tesla’s attorneys with Irell & Manella argued plaintiffs didn’t investigate their claims, and ignored facts that showed the cars were not prone to fires and actually some of the safest on the market.
