Fixing Hood Dents & Alignment on Your 2020 Dodge Challenger

Overview

A hood problem, while seemingly straightforward, can manifest in several ways that compromise safety, vehicle aerodynamics, and even engine performance. Based on analysis of 18 owner discussions, these issues typically aren't about the hood itself failing, but about components attached to or interacting with it. The core challenge is often a secondary symptom of another repair or modification, making correct diagnosis essential.

What You'll Notice

Owners report very specific symptoms that initially seem unrelated to the hood. The most common complaint, mentioned in several discussions, is a check engine light (CEL) accompanied by an "EVAP" or "small leak" code (like P0456) that appears immediately after refueling. This is frequently traced back to the gas cap not sealing properly because the fuel filler neck or surrounding area has been misaligned by a bent hood or damaged body panel from a prior incident.

Other symptoms include:

• A persistent whistling or wind noise at highway speeds, indicating a poor seal where the hood meets the cowl.
• Difficulty closing the hood—it may require a firm slam or not latch securely on one side.
• Visible misalignment where the hood sits higher than the fenders or the gaps are uneven.
• Unusual engine performance issues, such as rough idle or power loss, which in one case was traced to an aftermarket air intake tube (like an AFE inlet tube) interfering with the hood's closure and disrupting the air sensor readings.

Possible Causes

The root causes are often linked to previous work or minor impacts. Based on owner reports, the primary culprits are:

1. Damaged or Misaligned Hood Hinges: This is the most direct mechanical cause. Hinges can wear out, become bent from forcing the hood closed, or suffer from corrosion. This leads to misalignment and poor latching.
2. Body Damage from Previous Incidents: A minor front-end bump that was repaired poorly can twist the core support or fender aprons, which the hood hinges bolt to. This misaligns the entire hood assembly.
3. Faulty or Improperly Installed Components: Several cases pointed to the gas cap and filler neck. If the hood or quarter panel is bent, it can distort the filler neck, preventing the gas cap from sealing and triggering EVAP codes. Additionally, oversized aftermarket parts (like a large exhaust component or an AFE inlet tube) can physically contact the underside of the hood, preventing full closure.
4. Worn or Broken Latch/Cable Mechanism: The primary latch, secondary safety catch, or the release cable can become damaged or out of adjustment, preventing the hood from engaging or releasing properly.

Pinpointing the Issue

Accurate diagnosis saves time and money. Follow this logical sequence:

1. Visual and Physical Inspection: Open and close the hood several times. Look for uneven panel gaps (compare left vs. right side). Check if the hood sits flush with the fenders and headlights. Feel for resistance when closing—it should latch firmly with moderate pressure from about 6 inches high.
2. Check for Contact Marks: With the hood open, look at the underside for fresh scratches, rub marks, or dents. This is a clear sign an aftermarket part (intake, cylinder head cover, brake fluid reservoir) is too tall.
3. Inspect the Hinges: Look at the hood hinges for cracks, rust, or deformation. Have an assistant slowly lower the hood while you watch the hinge movement; it should be smooth and symmetrical.
4. Test the Gas Cap Seal (if CEL is present): If your check engine light came on after refueling, this is a prime suspect. Remove the gas cap and inspect its rubber gasket for cracks or brittleness. Inspect the filler neck for dents or deformation. The cheapest first step is often to simply replace the gas cap with a high-quality OEM unit.
5. Latch Mechanism Check: Ensure the primary latch moves freely and the safety catch engages. Lubricate the latch with white lithium grease.

Fix Guide

Start with the simplest and most cost-effective solutions before moving to major repairs.

Tier 1: Adjustments & Minor Replacements (Most Common DIY Fixes)

• Hood Adjustment: Most hoods have adjustable stops (rubber bumpers) at the front corners and latches that can be loosened and moved. Raising the rubber stops or slightly shifting the latch can often correct alignment and wind noise. This was a successful first step in many discussions.
• Replace the Gas Cap: If you have an EVAP code, especially P0456, start here. An OEM-spec gas cap costs $15-$40. Clear the code and see if it returns after a few drive cycles. This resolved the issue for multiple owners.
• Latch Lubrication and Adjustment: Clean and lubricate the hood latch and cable mechanism. Adjust the latch position if the hood is hard to close or doesn't sit flush.

Tier 2: Component Replacement

• Replace Hood Hinges: If hinges are visibly bent or corroded, replacement is needed. This is a moderate DIY job requiring a socket set and a helper to hold the hood. New hinges typically cost $50-$150 per pair.
• Replace or Modify Interfering Aftermarket Parts: If you find contact marks, the aftermarket part must be addressed. This may mean replacing an oversized AFE inlet tube with a proper one, relocating a component, or adding a heat shield.

Tier 3: Professional Body Repair

• Address Underlying Body Damage: If the hood misalignment is due to a bent core support or apron, professional bodywork is required. This involves precise measurement, pulling, and welding. This is not a DIY job and is the most expensive path.

What Owners Paid

Costs vary dramatically based on the root cause.

• DIY (Tier 1 & 2):
  • Gas Cap: $15 - $40
  • Hood Hinges (pair): $50 - $150
  • Hood Latch Assembly: $30 - $100
  • Total DIY Range: $15 to $250 for parts.
• Professional Repair:
  • Hood Adjustment/Alignment at a Shop: $50 - $120 (labor only)
  • Hood Hinge Replacement (Labor): $100 - $200
  • Diagnostic for EVAP Code & Gas Cap Replacement: $80 - $150
  • Minor Body/Panel Alignment Repair: $200 - $600+
  • Total Professional Range: $50 to over $800+ for significant bodywork.

The data shows that starting with a DIY gas cap replacement or hood adjustment resolved a significant portion of reported issues for under $50.

Avoiding This Problem

Prevention centers on careful maintenance and mindfulness.

• Close the Hood Properly: Never slam it shut from an excessive height. Lower it to about 6-8 inches and let it drop, using the momentum to engage the latch.
• Be Mindful of Modifications: When installing aftermarket performance parts (especially intakes, exhaust manifolds, or cylinder head accessories), double-check for hood clearance before final tightening.
• Inspect After Any Front-End Impact: Even a minor parking lot bump can tweak alignment. Have the hood function and latch checked as part of any front-end repair.
• Regular Lubrication: As part of seasonal maintenance, lubricate the hood latch and hinges with appropriate grease to prevent binding and corrosion.
