After leaving a SC in northern Florida (Port Orange IIRC), I saw a message on the screen that said something about a problem and "car may not restart" I had about 150 miles to go and around 180 range, so I reduced the speed so I would not
I''m getting "Power Limited. OK to Drive" and "Power Reduced. Exiting and re-entering the vehicle may restore operation" after Supercharging. Usually it limits speed to 65-70, last time it limited to below 60, and throttle behaves like full turtle on my Gem, Smart, Bolt, and prior SR Y when at the bottom of the pack.

A VERY well known issue. So well known that they put a message stating to have it replaced and so well known that it was posted about at least once within the last two or three days and likely more since then.
Thinking about it some more, Tesla possibly suspects a short/leak to ground, which might be why they''re reluctant to replace the 12 volt battery. If they did that first, it might mask the short temporarily and/or kill a brand new battery. OK so time for an update, some more information but personally I don''t feel any closer to having a resolution.

Tesla is a leading brand in the electric car market, renowned for its innovative designs and advanced technology. However, like any other vehicle, Tesla cars are not immune to technical glitches and malfunctions. One such issue that Tesla owners have reported is the "Electrical System Power Reduced" message that appears on the dashboard.
This morning my wife put the MY in reverse, about to pull out of the garage, and she got a "power reduced - rear motor temporarily disabled" then "Vehicle shutting down - pull over safely" message. A forum for discussion of the Tesla Model 3 Electric Vehicle
The PCS was reading a 16v spike from the DC/DC main-pack to 12v system and (I assume as a safety measure) was shutting down support of the 12v system from the high-voltage system. So @JWardell when you said VCFRONT_a195 was a high voltage alert, you were exactly right. This is then followed by the VCFRONT_a180 alert telling you the 12v
I was driving about 25 mph when the car became sluggish and a message appeared saying "Power reduced: Exit and re-enter car - may restore operation" alert. I pulled in, put the car in Park, got out and back in again and the car returned to normal. I have read on the Tesla Motors Club forum several reports of this being caused by a failure
GTW_W018 - Electrical Power System Reduced GTW_W157 - Power Reduced BMS_F017 - Unable to Start Vehicle BMS_U008 - Acceleration and Top Speed Reduced The tesla rep told me to power off and sit for 2 minutes and restart the car. It was totally dead at that point. He told me to tow it to SC 93 miles away and wait for them to open tomorrow.
VCFRONT_a192 - "Electrical system power reduced. Non essential features may be unavailable." and VCFRONT_a402 - "Electrical system backup power is unavailable. Vehicle will consume more energy while idle." I''ve replaced the 12V with a new battery but the messages still pop up and non of my "Non essential features" work.
I assumed a bad station and tried to move to a different plug but the car would not shift and then gave the Electric System Power Reduced. I tried both soft and hard resets with no change. I
Contacted Tesla Emergency Roadside and they dispatched a tow truck. I had forced the vehicle to power-off completely from the Safety & Security menu but by the time the wrecker arrived the 12v system had completely died and we were unable to put the vehicle into tow mode. Had to use nylon skids to winch it onto the flatbed.
GTW_W018 - Electrical system power reduced Vehicle may shut down unexpectedly Today both screens are dead and won''t come back on after reset attempts (brake and scroll wheels). The doors handles and trunk/frunk are still working via key fob. 12V battery was replaced by Tesla service in February 2021.
Luckily the service center was able to look at it right away on Monday. They found that the cooling system sensors were hooked up in reverse order. The system was seeing that the fluid was not cooling since the outlet reading was higher than the inlet. Was quickly fixed and never had the issue in the 14 month that I''ve owned the car.
When we stopped at a supercharger the car would not charge. I assumed a bad station and tried to move to a different plug but the car would not shift and then gave the Electric System Power Reduced. I tried both soft and hard resets with no change. I then called Tesla and they set up the tow and gave me Uber credits.
If the low-voltage battery is not functioning correctly, it can cause electrical system power reduction warnings to appear on the dashboard. The low-voltage battery in a Tesla typically lasts for around 3-5 years, depending on usage and other factors.
You would think tesla would send roadside assistance since the car was not drivable. But the car is out of warranty due to being a 2017 and having 130K miles on it. All in all replacing a 12V battery and charging the aircon is literally the ONLY thing I have done to this car.
Around the end of September, I began to get GTW_w018 (Electrical system power reduced) errors that would show up, cut my AC, and then disappear a second later a few times every other drive or so. Over the last month, I have noticed that they only show up when it is above ~70F outside. Formed in 2006, Tesla Motors Club (TMC) was the first
Vehicle Hold is currently unavailable due to system constraints. When stopping, use the brake pedal to bring your vehicle to a complete stop and keep your vehicle stationary. The onboard charger in your vehicle has detected power supply disturbances in the electrical power grid. These disturbances interfere with your vehicle''s charging
Another possible indicator of a low-voltage battery issue is if the car struggles to start or exhibits other symptoms like dimming lights or reduced power. If the battery is determined to be the issue, it will likely need to be replaced. If your Tesla is under warranty, they will replace the 12v battery for free.
