Primarily seen on GM vehicles, the reduced power light is usually red and indicates that something is wrong, the vehicle has gone into “limp mode” – just like “we are limping” or another example “we have only one leg and can’t run.”  A fault in this system could be problematic.  Many times, this fault pertains to either functions in vehicle accelerating or transmission operations.  Should this light come on, you must get the vehicle in for service.

Limp modes vary, some limit your speed to no more than 25 miles per hour, allowing you to drive to a safe place although at a frustratingly slow speed.  You may need to have the vehicle towed from that point, especially if you have a long distance to your destination.  Other limp modes allow you to go 40 miles per hour, normally enough so that you can drive to a repair center on your own.

The reduced power light is nearly always red.  It indicates a problem that needs to be addressed immediately as differs from a yellow warning light.

A frequently asked question is, “How do you know if the car is safe to drive when a warning light comes on?”  The general rule of thumb is determined by the color of the warning light.  Yellow warning lights generally mean its ok to keep driving as long as there are no performance issues such as odd sounds or unusual smells or poor acceleration.  Red warning lights in general mean you should stop driving immediately, or at the least as soon as it is safely possible.  For example, you shouldn’t stop for a warning light in the middle of a bridge or on a freeway with no shoulder area.  You do need to take advantage of the first opportunity to safely pull over though.  Here at Express Auto RV Care Center we have seen many instances where someone drove just a couple of miles to get home and turned what could have been a $400 dollar repair to $2000 or more due to not understanding the importance of seeking immediate assistance.

In the case of a reduced power warning light, it’s generally red but you can continue to drive the vehicle long enough to get to a repair facility providing it has not limited you to an unsafe speed on the highway.  In that case it is best to pull over as soon as practical and call a tow truck.
