2014-2020 Chevrolet Impala Rear Door Assembly: Buyer's Guide to Shells & Swaps

Key Compatibility Warning: 'Impala' vs. 'Impala Limited'

Symptoms of a Failing Rear Door Assembly

Failure of the door assembly itself is almost always due to physical damage from an accident. However, components within the door can fail, leading to various symptoms. Deciding whether to replace the whole door or just an internal part depends on the issue.

• Visible Damage: Dents, deep scratches, or bent metal from a collision are the most common reasons for replacement. Minor dents can sometimes be repaired, but significant damage compromises the door's structural integrity and can lead to rust.
• Difficulty Opening or Closing: If the door is hard to open, close, or sags on its hinges, it could be misaligned from an impact or have worn hinges/bushings. This can damage the latch, striker, and weatherstripping over time.
• Wind Noise or Water Leaks: A bent door frame or damaged weather seals will allow wind and water to enter the cabin. This can lead to interior damage, mold, and electrical problems.

• Rattling Noises: Rattles from the door while driving can indicate a loose interior panel, a failing window regulator, or other loose components inside the door shell.
• Electrical Malfunctions: While not a failure of the shell, problems like non-working power windows or door locks are common issues for this Impala generation. These are often caused by a faulty switch, motor, or lock actuator within the door.

Buying a Used 2014-2020 Impala Rear Door: An Inspection Guide

Purchasing a used OEM door is often the most cost-effective solution after a collision. Since these are typically sold as a 'shell', you will reuse your original interior panel, window, and electronics. Here’s what to check before you buy.

1. Verify It's a Shell, Not a Complete Door

Most recycled doors are sold as shells. This means you get the painted metal door itself. You or your body shop will need to transfer the following parts from your old door:

• Interior trim panel
• Window glass and window regulator/motor
• Door lock actuator and latch mechanism
• Exterior and interior door handles
• Wiring harness and speaker
• Weatherstripping and seals

2. Physical Inspection Checklist

• Check for Hidden Repairs: Look for signs of previous bodywork. Check for inconsistent paint texture, overspray on the edges, or thick, uneven material (body filler) by tapping on the panel. A magnet can help detect areas with thick filler.
• Inspect the Seams: Check the bottom and side seams for any signs of rust, bubbling paint, or separation. This is where water can collect and cause corrosion.
• Look for Dents and Dings: Run your hand along the entire surface to feel for small dents or waves that may not be visible in certain lighting. Pay close attention to the main body line, as this is difficult to repair perfectly.
• Check Hinge and Latch Areas: Ensure the areas where the hinges and latch bolt on are straight and free of cracks or stress marks. Damage here can indicate a more severe impact.
• Confirm the Correct Side: It sounds simple, but double-check that you are buying the correct side (Left/Driver side vs. Right/Passenger side).

While the door shell itself has no specific recalls, some related components on the 2014-2020 Impala do. No recalls were found specifically for the 2020 model year rear doors.

• Door Lock/Latch Failures: Some owners have reported issues with door lock actuators failing, causing the doors to not lock or unlock properly with the fob or interior switch.
• Electrical Gremlins: The 10th-gen Impala can be prone to various electrical issues, sometimes stemming from the Body Control Module (BCM) or wiring problems, which can affect door functions.

• Recall 14476A (2014-2015 models): This recall was for the center console storage compartment latch, not the main doors, but is worth noting for owners of those model years. The latch could fail to stay closed in a crash.

Cost Comparison for Impala Rear Door Replacement

Replacing a rear door involves the cost of the part and the significant labor to swap components and align the new door.

Replacement Overview & Difficulty

Replacing a door shell is a complex job best left to those with experience in auto body work.

• Difficulty: 4 out of 5
• Primary Challenge: The main difficulty is carefully transferring all internal components from the old door to the new one without causing damage, especially to the wiring harness and plastic clips.
• Alignment is Key: The new door must be precisely aligned with the body panels to ensure even gaps, proper closing, and a good seal against the weatherstripping. This requires patience and often a second person to help position the heavy door.
• Professional Help Recommended: Due to the need for component transfer and precise alignment, professional installation is highly recommended for a factory-quality result.
