If your car suddenly feels gutless, will not rev past a certain point, and maybe holds one gear, it has probably gone into limp mode. It feels alarming, but it is actually the car protecting itself.
What limp mode is
Limp mode, also called failsafe mode, is a protective state the computer triggers when it detects a fault that could cause damage. It limits power and revs so you can drive gently to safety or a garage instead of harming the engine or transmission.
Common causes
- A transmission fault or low transmission fluid.
- A boost or turbo problem on turbocharged cars.
- A faulty sensor sending an out of range signal.
- A serious misfire or an overheating warning.
What to do
Find a safe place and stop. Sometimes turning the engine off and restarting after a minute clears a temporary glitch. If it returns, the fault is still present, so have the codes read to find the cause rather than ignoring it.
Frequently asked questions
Can I drive in limp mode?
Yes, gently and only as far as needed to get home or to a garage. It is designed to let you limp along.
Will limp mode clear itself?
A temporary trigger may clear on a restart, but a real fault will bring it back until fixed.
A scanner reveals the fault code. See our car accessory guides.
