Hidden Car Damage After a Bump: Warning Signs

Why a small mark can hide more damage

A bumper can spring back into shape while parts behind it stay damaged. Even a slow bump can damage brackets, sensors or wires. It can also affect how the wheels line up or how the car’s safety systems work.

Warning signs before moving

• Fluid under the vehicle or a strong fuel smell.
• Tyre cuts, bulges, exposed cords or a wheel touching bodywork.
• Loose panels, broken lights or sharp edges.
• Smoke, steam, overheating or electrical burning smell.
• Airbag, brake, steering or other critical warning lights.

Keep away from traffic and do not inspect beneath an unstable vehicle.

Warning signs once moving

Stop safely if the car pulls to one side, shakes, makes scraping or knocking sounds, or shows new warning lights. Stop if the steering or brakes feel different too. Do not try to reach home if the car may be unsafe.

Checking cameras and safety sensors

Cameras, radar and parking sensors can sit behind glass, grilles and bumpers. They may seem to work even when they point the wrong way. Ask the repairer which safety checks the maker requires before and after repairs. Ask whether the sensors need to be set up again, and keep a record of the work.

Keep a record before repairs

Photograph all sides, warning lights and the vehicle’s position where safe. Record mileage and symptoms. Do not dismantle safety systems yourself. An insurer or repairer may need to inspect the damage before work begins.
