   While my wife was driving, the high-voltage battery failed and the car went into reduced power/limp mode. Tesla later determined that coolant had gotten into the high-voltage battery and caused it to fail. My main concern is that we had no warning that there was a coolant leak or that coolant was getting into the battery. There was no low-coolant warning or anything telling my wife that there was a serious problem developing. By the time the car started giving high-voltage…

   I am reporting a front suspension failure on my 2018 Tesla Model 3 Dual Motor, that appears relevant to NHTSA Preliminary Evaluation PE26006 and similar to Recall 23V-235. While driving slowly in a parking lot, I heard a clunk and felt the front wheel/steering alignment become slightly skewed. After entering the highway, the vehicle developed severe vibration and became unstable and difficult to control. I exited and stopped as soon as safely possible. While attempting to…

   On March 21, 2025, my Tesla Model 3 Long Range entered "Power Reduction Mode" — a safety feature that limits power to protect the high-voltage battery from overheating or failure. Tesla later diagnosed a coolant leak near the battery area. Their own service advisor stated in writing that the failure was “most likely related” to the battery’s thermal management system — the very system responsible for regulating battery temperature and preventing damage. Despite the…

   If both brake and throttle pedals are depressed simultaneously for a fraction of a second the software does two things: 1) raises a warning to that effect on the computer display and, 2) greatly reduces motor output, limiting acceleration. Item two is the safety concern. Removing the foot from the left pedal does not immediately remove the power restriction. There is a few second delay for that to take place. As a result I find myself expecting to be able to merge rapidly or…

   PTC Heater failed. This is a critical component that helps to maintain the battery's temperature within safe operating range. The only alternative is to replace this PTC Heater. Till the replacement is done, EVs battery may not maintain safe operating temperature range and could cause the car - not drive able. I consider this a significant safety risk. Cabin temperature cannot be maintained as well. Cause for PTC Heater failure is known - "change in temperature" could cause…

    The High Voltage Service Panel is part the battery which is part of the manufacturer warranty and drivetrain. A lot of Tesla cars had this problem and they are being charged $1800 to $2000 to “fix” this common failure. The problem is that the battery stop receiving the full amperage to charge the battery appropriately. In my case, I started charging more frequently on Superchargers during a long trip to different locations without a Level 2 homecharger and stopped several…
