Most drivers probably don’t think twice about how much their vehicle relies on the engine while it’s running. Beyond powering the car, the engine also supports systems like steering and braking. That’s why turning a car off while it’s still in drive, or having it unexpectedly shut off while driving, can quickly become extremely dangerous.

Here’s what drivers should know about why vehicles shut off and when repeated stalling problems could potentially point to a defect.

Key Takeaways: 

• Turning a vehicle off while in drive can make steering and braking difficult. 
• Cars may shut off unexpectedly because of fuel, electrical, ignition, or engine-related problems. 
• If a newer vehicle repeatedly shuts off while driving, it could potentially qualify for protection under the California Lemon Law.

Is It Bad to Turn the Car Off When It’s in Drive?

Turning your car off while it’s in drive is considered unsafe and should be avoided whenever possible. When the engine shuts off, the vehicle doesn’t stop right away, but you immediately lose a few important systems that help you stay in control. 

Over time, repeatedly shutting the engine off the wrong way can also end up putting unnecessary strain on certain parts.

What Happens If You Turn Your Car Off in Drive?

As mentioned above, when you turn your car off in drive, the engine will stop, but the car will likely continue moving because it still has momentum, even though it’s no longer being powered. Additionally, Most modern vehicles rely on power-assisted steering and braking systems. So, once the engine shuts off, those systems may still work for a short time, but steering will typically become a lot stiffer and braking may require a lot more pressure from the driver. 

Dashboard warning lights may also appear because the vehicle’s onboard systems detect that something’s lost power and is no longer functioning as it should.

Could You Accidentally Turn Off Your Car While Driving?

It’s possible to accidentally turn your car off while driving, but it doesn’t happen often, and it would depend on the type of vehicle you have. In cars with traditional keys, a loose or bumped key could potentially shift out of position, while pressing the push-button start at the wrong time in a newer vehicle might also shut the engine off, though most modern systems are designed to prevent this. 

On the other hand, a worn ignition switch or electrical fault could cause the car to shut off without warning.

What Would Cause a Car to Shut Off While Driving?

If your car turns off on its own, there’s a good chance there’s an underlying issue that needs your attention. Running out of gas is the most straightforward explanation, but electrical issues like a failing battery or alternator could also unexpectedly cut power to the engine. Overheating is another possibility, since some cars will shut down completely to prevent damage. 

That said, there are usually warning signs before a full shutdown. If you notice certain dashboard lights or unusual noises, it’s probably best to have it checked sooner rather than later.

What Should You Do If Your Car Shuts Off While Driving?

Above all else, the most important thing to do is to stay calm and simply focus on getting your car to a safe location. Even without power steering, you should still be able to steer the vehicle and guide it toward the side of the road. You’ll also want to turn on your hazard lights to alert nearby drivers. 

Once your car is stopped and a safe distance away from oncoming traffic, try restarting your engine to see if it’ll start again. Regardless of whether it turns on or not, it’s usually best to just call roadside assistance or a tow service to bring your vehicle to a mechanic or the dealership rather than risk driving it again for the time being.

Can You Fix a Car That Shuts Off While Driving?

The short answer is sometimes! In some cases the solution may be as easy as replacing a worn-out part, like a sensor or an ignition component. Or, it could end up involving electrical work or having a mechanic diagnose an even more complex engine issue. 

If your car keeps shutting off and repairs aren’t solving the issue, it could go beyond just a typical mechanical problem. In fact, in some cases, it might qualify as a defect under the California lemon law if you’re a resident.

What Qualifies as a Lemon in California?

If your 2021 or newer vehicle continues to shut off while driving despite multiple repair attempts, it could potentially qualify as a lemon under California law. Generally speaking, California’s Lemon Law applies when: 

• The problem seriously affects the vehicle’s safety, performance, or overall value.
• The manufacturer or dealership has been unable to successfully repair the issue after multiple attempts.
• The defect first appeared while the vehicle was covered under the manufacturer’s warranty.

If your car meets these criteria, then you should consider consulting a California lemon law attorney. Also, try your best to keep any repair records and dealership invoices since they could end up becoming important evidence if you submit a claim.
