- Avoid DIY adjustments; improper alignment attempts can worsen structural problems.
3. Unusual Noises During Driving
Post-accident, you may hear strange sounds such as squeaks, clunks, or rattling that were not present before. These noises often indicate hidden damage to the suspension, steering, or chassis components.
Common Sources
- Suspension Damage: Bent control arms, struts, or sway bars can produce clunks when driving over bumps.
- Loose Panels: Misaligned or partially detached panels can rattle at certain speeds.
- Exhaust or Engine Components: Impact may shift engine mounts, exhaust systems, or heat shields, creating vibration noises.
Why It Matters
Ignoring these noises can lead to accelerated wear on critical components, reduced handling performance, and increased risk of mechanical failure.
Recommended Action
- Schedule a professional inspection immediately after an accident to detect and repair suspension, chassis, or engine mount damage.
- Diagnostic testing may include test drives, visual inspection, and computerized alignment checks.
4. Steering or Handling Issues
One of the most dangerous signs that your car needs collision repair is changes in steering or handling. After a collision, even minor shifts in frame alignment can dramatically affect the vehicle’s responsiveness.
Common Symptoms
- Car pulls to one side when driving on a straight road.
- Steering wheel feels off-center or crooked.
- Vibrations or shaking during braking or acceleration.
Potential Causes
- Frame Damage: A bent or twisted frame can misalign suspension and steering geometry.
- Suspension Damage: Struts, control arms, or tie rods may be bent or compromised.
- Wheel Misalignment: Collisions can alter camber, caster, or toe settings, affecting handling and tire wear.
Risks
- Increased accident risk due to reduced vehicle control.
- Premature tire wear or damage to suspension components.
- Compromised braking and emergency maneuver performance.
Recommended Action
- Have a certified collision repair shop perform a full suspension and alignment inspection.
- Avoid extended driving until the problem is diagnosed, as continued use can worsen damage.
5. Fluid Leaks or Engine Performance Issues
Accidents can also affect a vehicle’s engine, transmission, and other critical systems. If you notice leaking fluids or changes in engine performance, collision repair may be necessary.
Common Indicators
- Puddles of coolant, oil, or transmission fluid under the car.
- Reduced engine power or hesitation during acceleration.
- Strange engine noises or warning lights on the dashboard.
Why It Happens
- Radiator or Cooling System Damage: Front-end collisions can puncture or crack radiators and hoses.
- Oil Pan or Transmission Damage: Impact can dent or crack components, leading to leaks.
- Sensor or Electrical Damage: Airflow, engine, or transmission sensors may be misaligned or disconnected.
Risks
- Continued driving with fluid leaks can cause severe engine or transmission damage.
- Leaks may create slippery surfaces, increasing accident risk.
- Undetected electrical issues can affect multiple vehicle systems, including safety features.
Recommended Action
- Have a professional mechanic perform a full inspection and pressure test of fluid systems.
- Repair or replace damaged components immediately to prevent cascading mechanical failures.
6. Airbag Deployment or Warning Lights
If your airbags deployed during a collision—or if airbag warning lights illuminate afterward—your car requires immediate collision repair.
Importance of Airbags
- Airbags are designed to deploy only in significant impacts. Deployment indicates the vehicle has experienced structural stress.
- Even if the airbags did not deploy, warning lights may signal sensor damage or misalignment.
Risks
- Non-functional airbags increase injury risk in subsequent collisions.
- Faulty sensors may trigger false warnings or fail to deploy safety systems during a crash.
- Insurance claims may require professional repair certification to restore full airbag functionality.
Recommended Action
- Avoid driving until airbags and sensors are inspected by a certified collision repair shop.
- Have all airbag-related components replaced or recalibrated according to manufacturer specifications.
7. Visible Frame or Undercarriage Damage
Sometimes damage is not immediately obvious from the exterior. A bent frame, cracked suspension mounts, or damaged undercarriage components may only become noticeable upon close inspection.
Signs to Watch For
