Feds close investigation of Tesla battery fires

KDWN

DETROIT (AP) — The U.S. government’s auto safety watchdog has closed an investigation into Tesla electric car battery fires after the company said it would install more shields beneath the cars.

The shields, an aluminum bar, a titanium plate and another piece of aluminum, will supplement a quarter-inch-thick aluminum plate now on the Model S, the only model that Tesla now sells. They’re designed to stop road debris from penetrating the car’s battery pack.

The National Highway Traffic Safety Administration began investigating the Model S last year after two battery fires that were caused by road debris. In each case, one near Nashville, Tennessee, and another near Seattle, debris punctured the aluminum shield and the battery, touching off fires. Drivers were able to safely pull off the road and escape without injury, but the cars were destroyed.

Tesla CEO Elon Musk said in a statement Friday that the company will retrofit Model S cars sold in the U.S. with the new shields, at no cost to owners. At the end of February, Tesla had sold about 22,000 of the cars in the U.S., according to Autodata Corp. The additional shields will be provided upon owner request or as part of normally scheduled service, the statement said.

The move is not a recall, a Tesla spokeswoman said.

Earlier, Tesla issued a software update that raised the Model S ride height to help deal with the issue.

“Tesla’s revision of vehicle ride height and addition of increased underbody protection should reduce both the frequency of underbody strikes and the resultant fire risk,” NHTSA said in documents posted Friday on its website. “A defect trend has not been identified.”

Musk said in his statement that the moves bring the risk of debris striking the battery “down to virtually zero” to give Model S owners complete peace of mind. The new shields, he wrote, are not needed for a high level of safety, but it’s valuable to minimize inconvenience to owners and address what he said were misperceptions about electric car safety.

Tesla also said it added the shields to cars in production starting on March 6.

DETROIT (AP) — The U.S. government’s auto safety watchdog has closed an investigation into Tesla electric car battery fires after the company agreed to install more shields beneath the cars.

Tesla says the shields will prevent roadway debris from damaging batteries and possibly causing fires.

The company will retrofit Model S cars sold in the U.S. with the new shields. It sold about 22,000 through February.

The National Highway Traffic Safety Administration says the shields and raising the ride height should reduce underbody damage and fire risk. Tesla says the action is not a recall.

The company says it will add an aluminum bar, a titanium plate and another piece of aluminum. The shields are designed to ward off the type of debris that caused fires in two cars last year.
