2021 Ford Bronco Sport Wireless Charger: Diagnosing Common Problems

Symptoms of Failure & Common Complaints

The wireless charging system in the 2021 Ford Bronco Sport is a source of frequent complaints from owners. While complete failure is possible, many issues relate to poor performance and compatibility problems. It's important to distinguish between a truly broken module and the unit's inherent design limitations.

Most Common Issues:

• Intermittent Charging or Disconnecting: The most common complaint is that the phone starts and stops charging repeatedly. This is often caused by the phone shifting on the large, slippery surface during normal driving, leading to misalignment with the charging coil. The issue is so prevalent that a constant stream of "wireless charging activated" 🎬 Watch: See how the factory wireless charger behaves in action notifications can become a major distraction.
• Phone Overheating: Many users report that the charging pad makes their phone extremely hot, sometimes to the point where the phone's internal safety features stop the charging process to prevent damage. This is often a sign of inefficient power transfer, where energy is lost as heat instead of being stored in the battery.
• Extremely Slow Charging: Even when it works, the factory charger is often described as "pathetic" and providing very little power. Owners report driving for an hour with only a 5% increase in battery life. This is partly due to the low wattage of the factory unit (around 5W) compared to modern phone capabilities.
• Complete Failure (No Charging): In some cases, the module may fail entirely and not charge a phone at all. This can be a hardware failure within the module itself or a blown fuse.
• Incompatibility with MagSafe iPhones: Newer iPhones with MagSafe technology have known compatibility issues with the Ford wireless charger. This can cause poor performance or prevent charging altogether. Ford released a Technical Service Bulletin (TSB) to address this with a software update.

Known Issues, TSBs, and Recalls

Technical Service Bulletin (TSB) 22-2485

Ford issued TSB 22-2485 for "Wireless Accessory Charger Inoperative/Poor Performance With Magsafe Charging iPhones" on several models, including the 2021-2022 Bronco Sport. The issue is due to limited compatibility between the Wireless Accessory Charging Module (WACM) and Apple iPhone 12 and 13 models. The fix involves a software update for the WACM performed by a Ford dealership. If you are experiencing issues with an iPhone, this TSB is the first thing to investigate.

Recalls

As of mid-2024, there are no specific recalls issued by the NHTSA for the wireless charging module itself on the 2021 Ford Bronco Sport. However, it's always wise to check for the latest recall information using your vehicle's VIN.

Buying a Used Wireless Device Charging System Module

Given the widespread dissatisfaction with the OEM unit's performance, consider why you are replacing it. If your goal is fast, reliable charging, a used OEM module will likely provide the same frustrating experience as the original. Many owners opt for aftermarket solutions instead. However, if you need to replace a completely dead unit to restore factory functionality, a used OEM part is a cost-effective option.

What to Check Before You Buy:

• Verify the Part Number: Ensure the part number is M1PT-19J235-AA. This module was used across several Ford models like the Escape and Edge, so verifying the number is crucial.
• Inspect the Connector: Check photos for any damage, corrosion, or bent pins on the electrical connector. A clean, undamaged connector is essential for proper function.
• Check the Charging Surface: Look for any deep scratches, cracks, or signs of heat damage (discoloration, warping) on the charging pad itself.
• Ask About the Source Vehicle: If possible, find out the options on the vehicle the part came from. Confirming it came from a Bronco Sport or a compatible Escape with the correct trim level can increase the chance of compatibility.
• Consider the TSB: A used module will likely not have the updated software from TSB 22-2485. If you have a MagSafe iPhone, you may still need a trip to the dealer for the software update after installation.

Cost of Replacement

Pricing can vary based on supplier and condition.

Installation Overview

Replacing the wireless charging module is a relatively straightforward task for a DIYer with basic tools. The module is located in the center console, below the rubber mat in the storage tray. The process involves carefully prying up plastic trim panels around the center console to gain access. No specialized tools are required, but a set of plastic trim removal tools is highly recommended to avoid scratching or breaking the panels. The module itself is typically held in by a few screws. The main challenge is the disassembly and reassembly of the console trim.
