Tesla (TSLA) has equipped its vehicles with a dog mode, so pet owners are able to keep their dog inside the vehicle at a comfortable temperature even on a hot day. But for one dog owner, it posed a potential problem, which Elon Musk has vowed to fix.

Tesla introduced dog mode back in February after a Twitter follower asked for the feature, Business Insider reported. Just as one would expect, dog mode operates the air conditioning so a pet owner can keep their dog in the car without worrying about them overheating.

A message on the car’s display also lets passersby know that the pet owner hasn’t forgotten about their dog by flashing a message that says, “my owner will be back soon.”

The feature is designed to keep dogs safe while unattended in the vehicle, but one Twitter user warned Musk of an issue with the system.

Esports CEO Rahul Sood sent a tweet to the Tesla CEO, telling him how the dog mode feature on his car seemed to let him down. According to Sood’s tweet, when he turned on dog mode, his car still reached 85 degrees in the summer heat with his dog inside.

Sood said to Musk, “ It's hot as all hell in Seattle. Today I used dog mode and luckily I kept the app open, to my horror the car was 85 degrees and climbing!

“ Dog mode only works if in auto, if you manually set the fan and leave the AC turns off. ”

Musk acknowledged the issue by responding back to Sood, “Fixing …”

Sood showed his appreciation for Musk’s response and tweet back, “You're the best. Thanks.”

Sood followed up the tweet with another message that read, “ Enzo thanks all y'all,” which was accompanied by a photo of his dog, Enzo.

The dog mode fix may be easy enough for Tesla to integrate as it can remotely roll out an update, which is exactly how the feature was released to vehicles initially, Business Insider reported.

Shares of Tesla stock were up 0.59 percent as of 11:44 a.m. ET on Thursday.
