US regulators for transportation safety have initiated a probe regarding the incident in which a brand-new Tesla apparently burst into flames, temporarily trapping the driver, with firefighters needing more than two hours to extinguish the blaze.

The cause of the fire in the Model S Plaid is yet to be determined.

Attorney Mark Geragos, a lawyer representing the owner of the car, called for the vehicle to be taken off the road.

“This is a harrowing and frightening situation and an obvious major problem,” AFP quoted Geragos as saying.

“Our preliminary investigation is ongoing, but we call on Tesla to sideline these cars until a full investigation can occur,” he added.

Geragos retweeted a post that said the car “spontaneously combusted” and the driver “was trapped & could have died.”

His firm released a photo showing the sedan, which has a price tag of $129,990, engulfed in flames.

Tesla is yet to issue a comment on the incident, the AFP report said.

Firefighters said the car was ablaze when first responders arrived at the scene in a township near Philadelphia.

They had to take special precautions due to the car’s large battery, which was on fire, with “copious” amounts of water poured on the Tesla for more than two hours, according to firefighters.

The National Highway Traffic Safety Administration told AFP it is probing the fire.

“If data or investigations show a defect or an inherent risk to safety exists, NHTSA will take action as appropriate to protect the public,” a spokesperson said.

The investigation comes as US safety regulators are focusing on accidents involving cars made by Tesla and other auto manufacturers with driver assistance systems.

The move comes after a fatal Tesla crash in Texas earlier this year in which police said there was no one behind the wheel.

Tesla has said the car’s Autopilot system was not engaged in the incident and that it believes the driver was indeed behind the steering wheel.

Tesla’s technology also garnered unwanted publicity from Consumer Reports testers who demonstrated how to “fool” Autopilot into driving a Tesla without anyone behind the wheel.

The company describes Autopilot as a driver enhancement system that, despite its name, requires a human operator.
