2022-2023 Bolt EUV Tailgate: Camera Options (UV2/UVB) and Replacement Guide

Key Variants and Compatibility Warnings

Before purchasing a replacement tailgate for a 2022-2023 Bolt EUV, you must identify your vehicle's factory-installed camera system. The wiring and mounting points within the tailgate shell are different for each system, and they are not interchangeable. Using the wrong tailgate will result in non-functional safety features.

Check your vehicle's Service Parts Identification (SPID) label for the correct Regular Production Option (RPO) code. This label is typically a sticker with a QR code located in the driver's side door jamb or glove box. The two key RPO codes are:

• RPO UVB: This indicates the standard HD Rear Vision Camera.
• RPO UV2: This indicates the optional HD Surround Vision system, which uses multiple cameras to create a 360-degree, top-down view.

You must purchase a tailgate that matches your vehicle's original RPO code. Attempting to 'upgrade' from UVB to UV2 requires extensive and costly changes to other vehicle modules and wiring harnesses.

Symptoms of a Failing or Damaged Tailgate

Aside from obvious physical damage from a collision, several electronic or mechanical issues can indicate a problem with the tailgate or its components.

Latch and Release Problems

A common complaint involves the tailgate failing to unlatch. You might have to press the exterior release button multiple times for it to work. In cold weather, the rubber release button can become stiff and unresponsive. In some cases, the 'Trunk Open' warning light may stay illuminated on the dashboard even when the gate is securely closed, often pointing to a wiring issue. This can be caused by a failing latch actuator, a bad relay in the fuse box, or even a weak 12-volt vehicle battery.

Camera and Sensor Failures

A malfunctioning rear camera can present as a blue or black screen on the infotainment display when the vehicle is in reverse, sometimes with a "Service Rear Vision System" message. According to GM Technical Service Bulletin #19-NA-076, this can be caused by a faulty camera in UVB systems or require a software update for the Video Processing Module (VPM) in UV2 systems.

Wiring Harness Damage

The wiring that runs from the vehicle body to the tailgate is housed in a flexible rubber boot and is subject to constant bending. Over time, or after an improper repair, wires inside this harness can break. This can cause a variety of issues, including a non-functional latch, camera failure, or a persistent 'Trunk Open' warning.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no major recalls specifically for the tailgate structure, several TSBs address related components.

• TSB 22-NA-004: Some vehicles may have an improperly installed foam tape seal on the rear spoiler (attached to the tailgate), causing it to become loose or visible. The official fix is to remove the spoiler and install a new seal.
• TSB 19-NA-076: Addresses blue or black screen issues with the rear vision camera system. The solution depends on whether the vehicle has the UVB or UV2 camera system.
• TSB 18-NA-279: Provides information for when the passive unlocking feature for the doors and liftgate stops working. This can sometimes be accidentally disabled by holding the lock and unlock buttons on the key fob for three seconds.
• Vehicle-Level Recalls: The 2022-2023 Bolt EUV was subject to significant recalls for high-voltage battery fire risk and an issue with driver's airbag fasteners. These do not directly involve the tailgate but are important for owners to be aware of.

Buying a Used 2022-2023 Bolt EUV Tailgate

Purchasing a used OEM tailgate is often the most cost-effective solution, as complete aftermarket shells are generally not available. Careful inspection is key to getting a good part.

Step 1: Confirm Compatibility

First and foremost, verify the RPO code (UVB or UV2) of your vehicle and ensure the donor vehicle of the used tailgate matches. Do not take the seller's word for it; ask for the VIN of the donor car so you can verify its options or ask for a picture of the SPID label.

Step 2: Physical Inspection Checklist

When inspecting the part in person or looking at high-resolution photos:

• Check for Hidden Damage: Look beyond the outer paint. Inspect the inner shell for creases, bends, or cracks, especially around the window frame and mounting points.
• Signs of Previous Repair: A wavy finish, paint overspray on trim or glass, or the presence of body filler (check with a magnet) indicate a previous, possibly low-quality, repair.
• Rust: Check for corrosion along the bottom edge, under the spoiler, and around any holes for handles, lights, or emblems.
• Included Components: Most used tailgates are sold as a bare shell with glass. Verify if it includes the latch, camera, wiper motor, wiring harness, spoiler, and emblems. Assume you will need to transfer these parts from your old tailgate.
• Wiring Harness: If the harness is included, inspect it carefully for cut wires or damage, especially at the flexible boot area.

Step 3: Questions for the Seller

• Was the donor vehicle in a front-end or rear-end collision? A tailgate from a vehicle with front-end damage is preferable.
• What was the mileage of the donor vehicle?
• Can you confirm if it's from a Bolt EUV (not a standard EV) and what camera option it had?

Replacement Overview

Replacing the tailgate is a moderately difficult job that is best performed with a helper due to the part's size and weight.

• Difficulty: 3/5
• Estimated Time: 3-5 hours (includes swapping all components)
• Common Tools: Socket set, trim panel removal tools, screwdrivers.

The general process involves removing the interior trim panel, disconnecting all electrical connectors for the latch, camera, and lights, detaching the gas struts, and unbolting the hinges. The process is then reversed for installation. The most time-consuming part is carefully transferring all the original components to the new tailgate shell.

Cost Comparison

Prices for a replacement tailgate can vary significantly. All used parts will also require painting to match your vehicle, which can add several hundred dollars to the total cost.
