“Car isn't cooling while supercharging. Problem originated while at Tesla Collision in Fort Lauderdale. Mike DiPietro, the general mgr stated they don't have a supercharger at Tesla Collision Fort Lauderdale to test it and they're not willing to drive it to the supercharger to test it because it's a service issue. When I dropped the car off it cooled while supercharging and now that it's not cooling while supercharging it presents a fire and safety hazard because it will only cool the moment the car is unplugged from the supercharger and then cools full blast for 45 minutes after the car is unplugged. I am well aware of the proper functioning of the cooling of 2015 Tesla Model S P90DL's because I have two of them and have since 2017. The fact that the cooling system kicks ONLY AFTER I UNPLUG from the supercharger clearly indicates the car sees a need to cool but because of a software issue. MIKE DIPIETRO, THE GENERAL MGR OF TESLA COLLISION FORT LAUDERDALE IS NOW THREATENING TO SUE ME BECAUSE I'M REPORTING A FIRE SAFETY/ACCELERATED BATTERY DEGRADATION ISSUE AND I SIMPLY WANT TO PICK THE CAR UP IN THE CONDITION WHICH i DELIVERED IT WHERE THE SUPERCHARGING WAS…”
“The component that Tesla has stated is the part that is failing is the MCU (Media Control Unit) which was a recalled part at one point but then Tesla decided to replace only a single part of the MCU which was the eMMC (embedded MultiMedia Card). Luckily the vehicle was not driving when it completely shut down and would not start back up but I was stuck in a restaurants drive-thru for roughly 4 hours till I could get a tow truck to come tow it. The tow truck had to put the car on dollies as the vehicle would not enter tow mode nor would it enter its emergency neutral mode so the vehicle could be moved. The windows would not go up or down and luckily the trunk was able to open because if not then I would have been stuck outside my vehicle as the door handles did not come out after I got out of it and closed the door behind me. Please read the messages from the tech as you will see that they tried to act as if they did not know what was going on with my vehicle but then i asked something else and they stated exactly what the issue was but supposedly could not confirm it was that unless they charged me a diagnosis fee and "got hands on" which I'm sure that info of…”
“Bought the car used. Had issues with rear drive unit that was replaced under warranty. Similar issue before warranty expired and was checked out by Tesla and noted to be " normal" noise. Later the nose got louder and repeat diagnostic recommended RDU to be replaced at a cost of nearly $8500. I believe that the RDU on older models were defective.”
“The Model S, which was bought in 2015, had a sudden acceleration while I was trying to park near the entrance gate of the parking lot. The accident happened on May 25, 2023. Fortunately, nobody got hurt and the car was totaled. I feel strongly that this should be investigated, as this can be a very serious public safety issue. It was inspected by the insurance company. There were no warning messages prior to the failure.”
“Driving my car and it completely gives out in the middle of traffic without any warning or alter almost causing an accident. When asked about the absence of alert they said I may or may not get one and I should be lucky it just cut off (randomly in traffic mind you) because if it didn’t it would’ve burst into flames. Being the Rear Drive Unit is the second most important part of the vehicle an alert should be given 100% of the time as no alert could cause injury to myself or other drivers. This means there are other Tesla drivers out there with a probable chance of their randomly car stopping without any control of the vehicle endangering lives. This oddly happens 60 days outside my 8 year warranty when I haven’t any issues at all and receive alerts for everything down to my fob key being low on battery. In addition the whole time they were just trying to convince to get a new one because they just happen to be running a limited time promo that I can transfer my free supercharging to a new vehicle if I purchased. A lot of people have reported (down to the day) of their car dying suddenly after warranty but no avail Tesla says they won’t goodwill repair my…”
“Rear drive unit failure Failed while driving, letters turned red and car became unresponsive. Car later became responsive between 3-10 seconds. Has occurred 5 times in a week. Dealer claims moisture to drive unit is what caused it and repair was covered under warranty except the harness attached to it, dealer charged me $599 for the harness. If seals are failing and allowing moisture to happen, which then leads vehicles to be unresponsive while driving is a huge risk. Please look into this, there are others online with the same issue”
