2020-2023 GR Supra Wireless Charger: Failures, Overheating, and Replacement Guide
Diagnosing and replacing the often-problematic wireless charging module in your A90 or A91 Supra, and what to know before buying a used one.
- Many issues like overheating and slow charging are design flaws, not failures; a replacement part will not fix them.
- Replacement is plug-and-play and does not require any dealer programming or calibration.
- This part is shared with the BMW G29 Z4, which can help when searching for a used replacement.
- Before buying, always test charging with your phone out of its case, as many cases interfere with the charger's function.
Common Issues & Failure Symptoms
Many owner complaints about the GR Supra's wireless charger are related to its design and performance rather than outright failure. However, when the module does fail, the symptoms are straightforward. It's important to distinguish between a faulty part and operational quirks.
1. Fails to Charge or Charges Intermittently
The most common failure is the module ceasing to function entirely. You will place a compatible phone on the pad, and the amber charging indicator light will not illuminate. In cases of intermittent failure, the light may turn on briefly and then shut off, or flash, indicating a problem. This can be caused by an internal electronic fault in the charging module itself.
2. Phone Overheating
While often a design issue, excessive heat can also be a symptom of a failing module. Owners frequently report that their phones become extremely hot on the charging pad, often causing the phone's internal protection to stop the charging process. This is partly due to the module's design, which includes a cellular signal booster that also generates heat. A malfunctioning module can exacerbate this issue.
3. Flashing Indicator Light
The charging pad has an indicator light that communicates its status. A solid amber light means it's charging, and solid green means charging is complete. If the light flashes, it indicates an error. This could be due to foreign objects on the pad, poor phone alignment, or an internal module fault. 🎬 See: Toyota Qi wireless charging troubleshooting tips If the light flashes even with a bare, correctly positioned phone, the module may be defective.
Pro Tip: Before assuming the module is broken, test it with the phone removed from its case. Thick cases, magnetic mounts, or credit cards in the case can interfere with charging and cause symptoms that mimic a faulty part. 🎬 Watch: Why your Toyota wireless charging keeps stopping Also, some phone software updates have been known to cause compatibility issues.
Known Issues, TSBs, and Recalls
As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) from Toyota for the wireless charging module itself on the 2020-2023 GR Supra. Most owner complaints are related to performance issues like slow charging and overheating phones, which are generally considered design limitations rather than defects. Some users on forums have noted that certain phones, like the iPhone 15 Pro, have had issues with the NFC chip being damaged by BMW/Toyota wireless chargers. Toyota has issued general technical tips for dealers acknowledging that accessories like MagSafe can interfere with charging performance.
Does the Module Need to be Programmed?
No, the wireless charging module does not require any programming, flashing, or coding after installation. It is a plug-and-play component. While some forum users have questioned if coding is needed because of a menu setting in the infotainment system, the consensus is that a replacement is a direct swap. You can disconnect the old module and connect the new one without needing a trip to the dealer.
Buying a Used GR Supra Wireless Charging Module
A used OEM module is an excellent cost-saving option, as it will function identically to a new one without the high dealer price. Since these units are known more for performance quirks than high failure rates, a used unit is generally a safe bet.
- Verify the Part Number: The most critical step is to match the part number. Known OEM numbers include 51166992204 (often seen as a BMW number) and Toyota numbers like 58804-WAA05. Always check the number on your original part before ordering.
- Inspect the Connector: Ensure the electrical connector and its pins are clean, straight, and free of any corrosion or damage. This is the most likely point of failure on a used electronic part.
- Check for Physical Damage: Look for cracks in the plastic housing or deep scratches on the charging pad surface. While cosmetic, severe damage could indicate the part was handled poorly or came from a vehicle with significant interior damage.
- Consider the Source: Since the GR Supra shares its platform with the BMW G29 Z4, the wireless charging module is often the same part. Broadening your search to include used Z4 modules can increase your chances of finding a compatible part at a good price.
Warning: Be cautious when considering this part for a 2024 model. Fitment for 2024 GR Supras may have specific requirements, such as needing the 2.0L engine with an automatic transmission. Always verify your vehicle's original part number is 6992204 before purchasing.

Frequently Asked Questions (FAQ)
Why does my Supra's wireless charger make my phone so hot?
The unit in the GR Supra is a combination wireless charger and cellular signal booster. Both functions generate heat in a small, enclosed space with little airflow, causing the phone and the unit to get warm. This is a widely reported characteristic of the system's design.
Is replacing the wireless charger a DIY job?
Yes, this is a relatively simple DIY task for most owners. It involves removing some center console trim panels to access and unseat the charging tray, disconnecting a single electrical connector, and swapping the unit. The process typically takes 20-30 minutes and requires only basic trim removal tools and a T20 screwdriver.
Will a replacement module fix the slow charging speed?
No, if your original module is functioning, a replacement will not improve charging speed or prevent overheating. These are inherent design characteristics of the OEM part. Many owners who are unhappy with the performance opt to simply disconnect the charger or use a wired connection instead.
Can I just remove the annoying lid over the charging tray?
Yes, many owners remove the top cover/lid to better accommodate larger phones or phones with cables plugged in. The cover is held on by simple clips and can be pried off. Several companies even sell 3D-printed replacement trays without the lid for a cleaner look.
