COMMON Signs You Need ENGINE REPAIR AND service

If you notice any of these, it’s worth having your engine checked before a small issue turns into a major repair. Grassland Car Care Center will run a full diagnostic and tell you exactly what your vehicle needs.

CHECK ENGINE LIGHT ON

A steady or flashing check engine light is your vehicle asking for attention. We read the codes and trace the warning back to its real source.

ROUGH IDLE OR STALLING

An engine that shakes at a stop or cuts out can point to ignition, fuel, or sensor problems that are best caught early.

KNOCKING OR TICKING

New noises from under the hood often mean a part is wearing or oil isn't moving the way it should. These are worth checking right away.

LOSS OF POWER

If acceleration feels flat or your gas mileage drops, your engine may not be running or firing the way it's meant to.

SMOKE OR BURNING SMELL

Smoke from the exhaust or a burning odor can signal an oil leak, a coolant problem, or something overheating.

ENGINE OVERHEATING

A temperature gauge climbing into the red means stop and call. Running hot can cause major damage quickly.

frequently asked questions

WHY IS MY CHECK ENGINE LIGHT ON?

Your check engine light comes on when your vehicle’s computer detects a problem somewhere in the engine or emissions system. The most common causes are a loose or failing gas cap, a bad oxygen or mass air flow sensor, worn spark plugs, or a catalytic converter issue, though it can also point to something more serious. The light tells you there’s a fault, not what it is. Our ASE certified technicians in Franklin, TN can read the codes and pinpoint the real cause.

A check engine light means your vehicle’s onboard computer has stored a trouble code for a fault it found in the engine, emissions, or a related system. It might be as minor as a loose gas cap or as significant as a misfire, a failing sensor, or a catalytic converter problem. The light alone won’t tell you which one, so the only reliable way to know is to have the stored codes read and tested at the shop.

Check engine light codes are cleared with an OBD2 scanner plugged into the port under the dash, and they will also clear on their own once the underlying problem is repaired and the vehicle completes a few drive cycles. The catch is that clearing a code does not fix anything. If the cause is still there, the light returns, and erasing the code wipes the data a technician needs to diagnose it. We recommend reading the codes first, then repairing the actual issue.

A blinking or flashing check engine light is more serious than a steady one and should not be ignored. It could mean your engine is actively misfiring, which can send unburned fuel into the exhaust and damage your catalytic converter in a short amount of time. Stop driving as soon as it’s safe and have the vehicle checked right away. Call us at 615-790-3600 to get a diagnostic check at our Franklin, TN shop.
