Tesla uses in-car notifications to proactively contact owners for service

In March of this year Tesla issued an internal service bulletin (SB-21-18-002) to replace refrigerant pressure/temperature (P/T) sensors in the heat pumps of 2020 and 2021 Model 3 and Model Y cars.

The faulty sensors would cause the heating and cooling system to malfunction, leaving owners without heat during the coldest months of the year.

Tesla has taken advantage of the connected nature of their cars to send an in-car notification to proactively make some owners about the potential problem with their heat pump.

According to the message that appeared yesterday on a 2021 Model 3 owned by one of our readers, the service request says his car is not currently experiencing a problem with the heating and cooling system.

However, Tesla warns that with the upcoming winter weather, the cold temperatures “may increase the likelihood of this condition occurring.”

The message goes on to say that Tesla will proactively replace the potentially faulty sensors to ensure “optimal heating performance during winter” and to contact them through the mobile app to schedule the service.

According to our reader, he took delivery of his Model 3 in February 2021, just before the service bulletin was issued. Based on a copy of the initial service bulletin, mobile service cannot perform this job so it requires a visit to a Service Center. This direction may have changed since the time it was first issued.

Have you also had this message appear in your car? Was mobile service able to complete the job? Let us know in the comments below.
