EV (Electric Vehicle) System Warning and Hybrid Service Warning Indicators

EV System

These are all EV (Electric Vehicle) or Power System Warning Indicator symbols. The first images are of a rather generic automobile with an exclamation point embedded inside. In yellow/amber it warns of an imminent threat from one of many EV systems. In red, it warns of a fault that must serviced immediately. Note that manufacturers tend to re-style the symbol to match the shape of their vehicles.

• Before continuing, is one of these truly your symbol?? If yes, continue on below.

Other Versions

For some EVs, these are the equivalent of the Check Engine Light. They indicate a possible problem in one or more of the following; the traction motor and inverter system, the charge port or charger, the lithium ion battery, the cooling system, or the shift control system. Pretty much any system that allows the vehicle to move might be at issue and a diagnosis by a qualified service shop will be required. HEV indicates a Hydrogen fuel cell and the FC indicates essentially the same.

The symbols above use an exclamation point and the letters HEV or EV for Hybrid Electric or Electric Vehicle in a triangle. Contact your dealer or authorized repair center before attempting to drive further.

Rivian variation

Rivian uses the red triangle symbol ad calls it a Fuse System Malfunction. As best as we can determine, this is a general electrical problem, and very likely with the high-voltage system. Have a qualified service shop look into this.

Service reminder

This next image is listed as a Service Indicator. However, since there are no filters to change or other routine maintenance required, this is likely an indication of a system problem, which must be addressed by a qualified service center. The image, in red, is that of a wrench or spanner split by a lightning bolt, although the bolt may be mistaken for a Z.

Note that the very similar looking image to the right is an Electronic Power Control or Engine Speed Limitation indicator. It is seen in internal combustion engine vehicles. So if you’re not in an EV click here for more.
