Get fixing car dents right

Before you start pulling or sanding, you need to know what you’re working with. Modern EVs use aluminum bodies, high-strength steel, and complex sensor arrays that change how dents behave and how they should be repaired. A dent on a fender might look simple, but if it crosses a sensor zone or hides a battery cooling line, the repair process changes completely.

Start by identifying the dent type. Paintless dent repair (PDR) works best for small, shallow dings where the paint is intact. If the metal is stretched or the paint is cracked, you’ll likely need body filler and repainting. Check the location carefully—dents on body lines or sharp edges are harder to fix cleanly and may require professional tools.

Gather your gear: a dent puller or slide hammer, sandpaper (80-grit for primer, 400-grit for smoothing), body filler, a spreader, and a wet-dry vacuum for cleanup. If the dent involves sensors, disconnect the battery first to avoid short circuits. EVs have high-voltage systems, so safety comes before aesthetics. Test your tools on a hidden area first to ensure they don’t damage surrounding panels or sensors.

Work through the steps

Work from low-risk checks to deeper repairs. Confirm power state, safe parking, and account access first. Then restart the interface, wait for it to reload completely, and test the original symptom. Avoid changing multiple settings at once because that makes it harder to know which step actually fixed the problem.

If the issue affects safety information, repeats after every restart, or appears with warning messages, treat the reset as a temporary diagnostic step rather than the final fix. Document the symptom and move to official support instead of stacking more DIY attempts.

  • Park and note the symptom
    Put the system in a safe idle state, then write down whether the screen is frozen, blank, slow, disconnected, or only failing in one app.
  • Try the normal restart first
    Use the standard screen or interface restart before changing settings, deleting profiles, or disconnecting accessories.
  • Retest one feature at a time
    Check touch response, audio, navigation, phone pairing, Wi-Fi, and app access separately so the failing path is clear.
  • Escalate repeated failures
    Contact official support when the screen stays black, warnings appear, or the same issue returns after a clean restart.

Fix common mistakes

Most dent repair attempts fail because the initial assessment is wrong. You might be trying to fix a problem that requires professional intervention, or using the wrong technique for the specific type of damage. Here are the errors that lead to poor outcomes.

Ignoring paint damage

Paintless dent removal (PDR) only works if the clear coat and paint are intact. If the paint is cracked, chipped, or missing, PDR will not restore the finish. Trying to push out a dent with broken paint leaves you with a smooth but unsightly surface that still needs body filler and repainting. Check the dent under bright light before starting. If the paint is compromised, skip PDR and plan for a traditional repair with Bondo, sanding, and paint matching.

Using the wrong heat source

For minor dents, heat can expand the metal to help it pop back. However, modern EVs have plastic bumpers and composite panels that melt easily. A standard heat gun can warp a bumper or blister paint in seconds. If you use heat, keep it moving constantly and use a lower temperature setting. Alternatively, use compressed air held upside down to spray freezing gas onto the dent; the rapid contraction can sometimes help pop small dents out without risking heat damage.

Pulling too hard or too fast

When using a dent puller or glue tabs, pulling too hard stretches the metal further away from its original shape. This creates "high spots" that are harder to fix than the original dent. Pull in short, firm increments. If the metal resists, stop. Forcing it can crack the paint or tear the metal. The goal is to gradually coax the metal back, not to rip it out with brute force.

Skipping the final check

After you think the dent is gone, check the surface under a direct side light. Shadows will reveal low spots or ripples you missed. If you see any imperfections, use a rubber mallet with a block of wood to gently tap high spots down, then repeat the pulling or heating process. Do not assume it is smooth just because it looks okay from a distance.

Fixing car dents: what to check next

Before investing time or money, it helps to understand the limits of DIY fixes and professional pricing. Modern EVs often use aluminum or high-strength steel, which can behave differently than traditional steel panels during repair.
