Tesla reportedly suffered a network outage Wednesday morning as hundreds of car owners filed complaints they were unable to connect their vehicles to the company's mobile app.
One Tesla owner said he accidentally locked his keys inside his car and could not access the remote app on his phone to open the door.
Robert Vogt, a Model S owner from Ann Arbor, Mich., told MSN his mobile app was down around 11:30 a.m. EDT.
"If you're unable to unlock your car and drive, that's a problem," he said.
Reports about the outage coincided with the company's stock falling more than 9 percent to $383.
Shares for Tesla were already falling Wednesday. One reason was disappointment on Wall Street with the company's Battery Day presentation, Bloomberg reported.
