Technical / Some Tesla owners unable to unlock their cars after network outage

New York: Tesla drivers locked out of their cars after a complete network outage hit its internal service and customer mobile app were able to get back in after about an hour. 

The hitch comes a day after the company lost $50 billion in its market value due to its failed 'Battery Day.' 

The mobile app holds a digital key and and only owners who have a physical version have been able to access and drive their vehicle - leaving those without stranded. 

Tesla's internal systems are also down, making it impossible for staff to process deliveries and orders. 

According to Down Detector, the outage is stretching across the US and over into parts of Europe.

Sources familiar with the matter told TechCrunch: The Tesla outage was caused by an internal break of their application programming interface (or API), according to sources familiar with the outage.'

Some consumers have had service restored, but others are still battling the outage. 

DailyMail.com has reached out to Tesla for comment and has yet to receive a response. 

Frank Lambert, a Twitter user and Tesla owner, was the first to sound the alarm about the outage.

'Tesla is currently having a complete network outage. Internal systems are down according to sources. On the customer side, I can't connect to any of my cars and website is not working,' Lambert shared in a tweet.

Lambert, who has three Tesla vehicles, said on the social media site that he was unable to connect to the cars using the mobile app.

Other users chimed in shortly after, stating they were experiencing the same issue. 

The Tesla mobile app holds a number of features for owners, including GPS Location to find their vehicle, Range Status to check the car's charge status and a section to schedule services.

One of the connectivity features on the customer side that has been affected is the digital key, but owners with a physical version have been able to access and drive their vehicles. 

However, some owner have been locked out of their vehicles.

Megan McChesney shared: 'Can't unlock my 3.. app is down.. can't log into the website either... been on hold for an hour and wait time still says over an hour. This is what I get for trying to save the planet.'

Down Detector, a website that monitors outages online, shows most of outage is being felt in the US and in major cities like San Francisco, Boston, New York City and Chicago. 

The outage has cross over the Atlantic, hitting parts of the UK, Germany and as far as Russia.

Tesla's website is also showing errors beyond the main page, with problems hitting the firm's energy products and leaving owners unable to monitor their systems, Electrek reports.  

Wednesday's outage is just the icing on the cake for Tesla, as the firm's 'Battery Day' was a flop among investors. 

CEO Elon Musk had promised to unveil new technology to cut electric vehicle costs, but when he did not deliver, stocks in Tesla tumbled more than 10 percent Wednesday. 

Investors slashed $50 billion from Tesla Inc's TSLA.O market value on Tuesday after Musk admitted it would be at least three years before it will cut electric vehicle costs so radically that a $25,000 car that drives itself will be possible.

Tesla's market cap dropped $20 billion in just two hours after trading closed Tuesday, as Musk and other Tesla executives presented their new battery and manufacturing strategies. 

Shares closed down 5.6 percent and had dropped another 6.9 percent after hours. They opened Wednesday at 5.4 percent and had dropped to 7.45 percent just after 11.30am ET.
