Car lacks power — why the engine has lost performance
Power loss can build up gradually or appear suddenly. When modern cars detect a fault they often enter limp mode, which deliberately limits power to protect the engine.
Possible causes
- Clogged air or fuel filter
- Turbocharger or turbo control problem
- Blocked particulate filter or EGR valve (diesels)
- Sensor fault triggering limp mode
- Ignition system problem
What you can safely check yourself
- Whether the Check Engine or another warning light is on
- Whether the problem disappears after restarting the engine
- Whether there are unusual noises or smoke from the exhaust
When to call a mechanic
If the car is in limp mode, drive gently and only to a safe place. If thick smoke comes from the exhaust or you smell burning, stop.
