    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    All, as an update: Tesla mobile service came out yesterday (August 3rd) and replaced my Restraint Control Module. This was after diagnosis that the module was stopping my car from going to sleep and causing excessive standby battery drain. This seems to be a very common problem and most likely...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    Tesla transferred me to a master Tech (apparently) yesterday and they now say that my Restraint Control Module needs to be replaced. They are sending out a mobile tech tomorrow (Thursday August 3) to replace it. What is interesting is that the previous tech couldn’t see that my car wasn’t...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    Hey, mine was fixed for a day. All symptoms returned after driving the car to work and back. The cameras are hot again and the car won’t sleep. I have been passed on to a higher level technician. This is frustrating! It has to be software

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    All, some positive news. After updating my car this morning (2023.20.9), the cameras cooled down. Tesla sent out a mobile tech and we performed a hard reboot about an hour later. So far the car has stopped humming (coolant pump is off now) and my car’s interior is slowly decreasing in temp. I...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    We had a temp drop where I live today and I decided to do a temp check of all the cameras around the car. My suspicion was correct, they are all hot to the touch, well above ambient temps. They are running nonstop continuously even with the car being “off.” I haven’t driven it for three days...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    This issue could constitute a lawsuit as the owners manual states “around 1% a day of loss” and not 12% a day. If we do some math for Canadian deliveries in this last quarter and assume this is widespread (which it is by these posts), then this issue is burning through approx 2.5 MW of...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    That is my worry. Technically we are all loosing our high voltage battery capacity for this issue over the car’s intended purpose (driving). I personally believe that heat soaking of the drive computer will effect the small resistors, capacitors, and all the small soldered joints (like last gen...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    No luck with Tesla service reps suggested fix (as I thought). After driving the car and parking it as asked, the car continues to consume 1.9% of the battery ever 5 hours for standby. If fact the car has used more power in standby so far then in driving since my last charge. I thought I would...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    I just got contacted by a Tesla service rep. They found that the car was registering two devices, but I only ever connected one (my phone). They worked with me to ensure that the second one was removed. I doubt this is a fix as my car keeps humming away as before. They asked for me to drive...

    New tesla model 3 RWD battery drain while parked problem and park assist unavailable

    My model 3 is having the same issue. The car has consumed 23% of the high voltage battery in standby over 3 days! I have had the car for just over a week. All was good for the first couple of days. You could hear the high voltage contactors engaging and disengaging as expected when walking...
