Buick Service 101: Is My Car Safe to Drive in Limp Mode?

The Check Engine light may cause a bit of momentary concern, but if you’ve never experienced a vehicle operating in what’s called “limp mode,” you may feel something closer to panic. What is it, what causes it, and when should you visit Patriot Buick GMC for help with all your Buick service needs?

What is Limp Mode?

Modern cars have an onboard computer called an ECU, or electronic control unit. It continually monitors your vehicle’s vital systems, issuing alerts if it detects something wrong. It enters limp mode in extreme cases where continued operation could cause further damage or a safety issue. This feature automatically reduces speed and redirects power from nonessential functions to compensate for mechanical issues. You won’t just see one or more warning lights; you’ll notice that your transmission may not shift gears, your speed is restricted, or that several accessory systems like the infotainment system cease operation.

What Should You Do When Your Car Enters Limp Mode?

You can drive for short periods in limp mode. If you’re within a few miles of home, there’s nothing wrong with getting the rest of the way there. However, if you’re far from your destination, it’s best to find a safe place to pull over – like a parking lot – and locate the nearest authorized GM service center. Getting to the root of the problem requires specialized diagnostic tools.
