I recently made my first road trip (670 miles) in my one-month-old Model 3 (Dual Motor). When I arrived at my destination, I pulled into my sister's garage with 49 miles left in my battery. The screen displayed a message stating “Battery low. There will be significantly less energy available if the battery gets colder. We recommend charging now.” (It was 40 degrees outside.) The outlet was on the other side of the garage, so we decided to have dinner and switch the cars afterward.
When I returned two hours later, the battery still showed 48 miles remaining. It started normally, but when I put the car in reverse and pressed the accelerator, it jolted to a halt and warned that the battery was too low and to recharge immediately. The car refused to back up even though it showed 48 miles in the battery. Fortunately, I was able to run an extension cord and give it some charge overnight.
The following morning, it had charged to 90 miles, so we took a short drive. When we returned with 62 miles remaining, I was again given the same warning when I put the car in park.
Is this normal? If so, how low can you safely go before you have to worry about being stranded after making a short stop? I’d appreciate knowing if anyone else has had this happen to them.
