Tesla Inc. is recalling thousands of recently built vehicles over an issue that can cause a sudden loss of battery power, increasing the risk of a crash. The problem stems from a faulty battery pack connection part, which can lead to loss of propulsion without warning, Tesla said in documents posted to the National Highway Traffic Safety Administration’s website. The company is recalling almost 8,000 Model Y SUVs and just over 5,000 Model 3 sedans produced from March through August of this year.
