2015-2016 Cadillac ATS & 2015 CTS Overhead Console: Sunroof Recall and Function Guide

Symptoms of a Failing Overhead Console

When the overhead console begins to fail, it can cause a range of frustrating electrical issues. Because the console controls multiple unrelated functions, you might notice one feature failing while others continue to work perfectly. This is often due to a failure in a specific circuit trace or switch within the console assembly.

• Sunroof Inoperable or Erratic: The sunroof may not open or close, or it may only work intermittently. This can be caused by a faulty switch in the console.
• Map Lights or Dome Light Not Working: One or more of the interior lights housed in the console may fail to turn on, or they might stay on continuously and drain the battery.
• Homelink / Garage Door Opener Fails: The integrated garage door opener may stop programming or fail to send a signal.
• OnStar or SOS Button Malfunction: The OnStar system may become unresponsive, which can be a serious safety concern in an emergency.
• Poor Bluetooth Call Quality: If the console's integrated microphone fails, people you call may not be able to hear you clearly.
• Rattling or Buzzing Noises: Loose internal components or a poor fit against the headliner can cause annoying sounds while driving.

Most of these failures will not trigger a Check Engine Light. However, a professional scan tool may find Body Control Module (BCM) diagnostic trouble codes (DTCs) related to communication or circuit faults with the console's components.

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

There is a significant safety recall related to the overhead console that affects these vehicles, specifically the 2013-2016 Cadillac ATS.

NHTSA Recall 15V463000 (Supersedes 15V106000)

General Motors issued a recall because the sunroof switches on the overhead console were not sufficiently recessed. This design flaw meant the switch could be accidentally pressed, causing the sunroof to auto-close unexpectedly and increasing the risk of injury. The initial fix under recall 15V106000, which involved a new trim plate, was found to be insufficient. The updated recall, 15568 (NHTSA ID 15V463000), requires dealers to install a revised roof console accessory switch trim plate at no charge. This recall applies to 2013-2016 Cadillac ATS models and is a critical safety repair. Owners should contact a Cadillac dealer to ensure this recall has been performed.

Programming and Calibration: Is It Plug-and-Play?

Whether a replacement overhead console needs programming depends on the vehicle's specific options. These vehicles use GM's Global A electrical architecture, which can complicate module replacement.

• Likely Plug-and-Play: If your console only controls basic functions like map lights and the sunroof, a used unit with the exact same part number is likely to be plug-and-play.
• Programming May Be Required: If your console includes features like OnStar or an integrated Homelink garage door opener, programming may be necessary for those specific features to communicate with the vehicle. While the lights and sunroof may work upon installation, the more advanced systems are often tied to the vehicle's VIN.

In many cases involving GM module replacement, a dealer or a qualified independent shop with access to GM's Techline Connect (SPS) software is required to perform programming.

Buying a Used Overhead Console for Your Cadillac ATS or CTS

A used OEM console is often the most cost-effective solution for a failure. Given the high cost of a new unit from the dealer, a quality recycled part can provide the same form and function for a fraction of the price. Here’s what to look for:

1. Verify Part Number 23365574: This is the most critical step. There are many visual similarities between GM consoles, but internal wiring and features can differ. You must match the OEM part number 23365574 to ensure compatibility.
2. Match Your Options: Ensure the replacement console has the same buttons as your original. Check for sunroof switches, OnStar buttons, and any other features. While the part number should guarantee this, a visual check is a good secondary confirmation.
3. Inspect for Physical Damage: Check for cracks in the housing, broken switch buttons, or damage to the electrical connector pins. Look for any signs of water stains or corrosion on the circuit board, which would indicate it was in a vehicle with a water leak.
4. Why Used OEM is a Smart Choice: A new OEM console can be expensive. Aftermarket replacements for this specific, complex module are not common. A used OEM part guarantees the same fit, finish, and quality as the original part that came with your car.

Overhead Console Replacement Cost

The cost to replace the overhead console can vary significantly depending on the source of the part and who performs the labor.
