Electronic Power Steering (EPS) Light on a Isuzu D-Max
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Electronic Power Steering (EPS) Light Means on a Isuzu D-Max
The EPS (electronic power steering) light on a Isuzu D-Max indicates a fault in the electric steering assist. Steering can become noticeably heavier, and the system may need a diagnostic reset or repair.
How Urgent Is the Electronic Power Steering (EPS) Light?
Urgency level for this indicator on the Isuzu D-Max: high. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Electronic Power Steering (EPS) Light appeared, how the Isuzu D-Max is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

Is It Safe to Drive With the Electronic Power Steering (EPS) Light On?
Whether it is safe to keep driving your Isuzu D-Max with the Electronic Power Steering (EPS) Light on comes down to urgency (high) and behaviour. As a rule, if the light is red or flashing, or the Isuzu D-Max is running poorly, stop somewhere safe and arrange help rather than pushing on.
