    23M3P - Burning and/or Overheating Electric Smell During High Performance Driving

    I have a relatively new (~3000 miles) Model 3 Performance.

If...

    Most will hate this question...[is there a way to play exhaust sounds when I accelerate?]

    All my life I've owned muscle cars, and made the switch to my M3 AWD a few months ago. Everything is perfect, however I'm missing the exhaust sounds of my old cars. Is there an app/program I can open that will play exhaust sounds as I accelerate?? There are some on the App Store but they are...

    "The bms have detected isolation failures conditions on multiple drive cycles"

    Hi, I have a Model S 85 2014. Nothing changed on the car, all original. While on a long road trip (UK to Spain) the car gave me different error messages (picture below). A bit of drama, but I was able to take it to the nearest Tesla Service Centre in Barcelona, Spain. Tesla UK told me the main...

    Model 3 Not drivable

    Hello Everyone, I'm not sure if anyone has had this issue before or any resolution, but last night, my motor (as it seems) blew on me. During a drive, I felt the front passenger brake lock up twice. As any rational person would, I pulled over and inspected, didn't see any issue. When I got...

    Rear Drive Motor Fault causing 12V Battery to discharge

    We got 2 Model Y LR AWDs in mid-December. This morning we went to open the door of one of them and nothing would happen. The app was perpetually trying to connect.

    Looking For Sport Rear Motor & Inverter Subassemblies

    I can get good drive unit assemblies in lots of places, and in fact, they've fallen precipitously in price the past year or so. But, I'd prefer to give a good home to a MS or MX PERFORMANCE ("Sport") rear drive unit, or the subassemblies, where the diff or gearcase got trashed in a side hit...

    Intermittent Drivetrain Noise

    During a recent 1,000 mile trip, I noticed my Model S 60D would make a faint noise under acceleration from the front of the car that sounded a little like a diesel engine. Often times, it would be masked by tire or wind noise. The more I pushed the accelerator, the louder the noise would...

    Motor/Gearbox bearing - what about that hum?

    So, I'm developing a new problem since a few weeks.. Between 120 kmh and 130kmh (75-85 mph), I have a hum that is quite apparent. It disappears as soon as I accelerate hard, but is there all the time when cruising at highway speed. Now I've read on the German TFF forum that I'm not the first to...

    Same motor in 85D as in the front of P85D

    When I took a test ride I was told that it's the same motor in the front of the P85D as in the back and front of the 85D. But when I look at the ordering pages it says 2x 188 hk in the 85D and 221 hk in the front of the P85D. Is it the same motor but different inverters or is anything else?

    How does motor and regen efficiency scale with power?

    I'm curious about the scaling of efficiency of a as you increase power, volume, and mass. I've been thinking about it since Elon mentioned a Tesla truck. Trucks tend to have a significant amount of mass, and when towing or carrying a heavy payload, the mass is increased even more. But with...
