    For the few months I've had my new MX 75D, I've taken great care not to overcharge the battery or let the charge run too low. I usually keep it around 60%. The other day I had charged the car afresh overnight as usual. My wife could not have driven the MX more than 20 miles when she got an error that the suspension was failing and the battery charge was too low. She immediately pulled over and managed to get the car onto the freeway shoulder before it went dead. The screen and other minor functions continued to work for a while then died just before the Tesla-certified tow truck arrived. Because they could no longer get the car into neutral (they actually could have, I was told later), they put plastic wedges beneath the rear wheels (the rear wheels would not rotate as they were locked by the parking brake) and pulled the car up onto the truck. The force of the tugging somehow caused the entire rear of the car to descend closer to the ground by at least a few inches or more, while the rear wheels remained fixed by the brake. This was painful to watch for a new Tesla owner. I'm certainly no mechanic but couldn't help but feel this could damage the car/suspension. At the Tesla Service Center, they verified the battery had failed and said they would be sending the pack to Fremont for an inspection. They assured me that the battery would be replaced with one that was brand new rather than refurbished. I'm still waiting on an estimate about when I'll get my MX back.

    Just curious to know if anyone else has had this issue with their Tesla and whether anyone thinks that the method of getting the MX onto the tow truck could have caused any damage. The guys who towed the car apparently could have fed power to the car externally and gotten it into neutral without much trouble. This is actually what these same guys did at the service center with their own equipment to get the car off the truck! They admitted they could have done that roadside as well in about 5 minutes or less. Great! :-(

    Hang in there. My guess is that Tesla will make you whole. Just stay and top of them and make sure they address all your concerns regarding the tow as well.

    This has nothing to do with how you treated the battery. You just got a defective one. It happens, no production line is perfect.

    Keep us posted.

    Thanks, Traxila and K-MTG for your posts. My experience wasn't quite so bad as the gentleman in the video. I'm hoping the the problem for my X was solely a battery failure. The replacement is supposed to arrive today and I may be able to pick up the car on Tuesday. Will keep you all posted about the outcome and cause of this issue.

    Got my MX back two days ago. Works great. They replaced the 75 KW battery, which seems like a massive undertaking, and all seems back to normal. No word on why the original battery failed. Guess I may never find out. Best to all out there at TMC!

    Battery capacity is measured in kWh, not "KW".

    You may not realize it now, but it will become more important when people (including possibly yourself) are also discussing charging rate, which is measured in kW.

    Great news! Very Happy to hear. That old battery will be put to use. Enjoy the new one.
