Some Tesla customers will have to wait longer to get a response from customer service due to a significant increase in vehicle deliveries, CEO Elon Musk said via Twitter on Wednesday.<br />"Due to a large increase in vehicle delivery volume in North America, Tesla customers may experience longer response times. Resolving this is our top priority," he said.<br />Tesla did not immediately respond to a request for comment on how long the extended response times will last or what percentage of customers may be affected. <br />
