2020-2023 Nissan Sentra Center Brake Light: Decoding the LED Assembly (26590-6LA0A)
This guide covers the integrated LED high-mount stop lamp assembly for the 2020-2023 Nissan Sentra, including failure symptoms, replacement costs, and what to check when buying a used unit.
- The part is a complete sealed LED assembly (26590-6LA0A), not a serviceable bulb.
- The major brake light recall for Sentras does NOT apply to 2020-2023 models.
- Failure symptoms include partial-outage (gaps in the light), flickering, or complete failure.
- Before replacing the assembly, always check the brake light fuse and ensure the main brake lights work to rule out a faulty brake switch.
Symptoms of a Failing Center Brake Light
Because the 2020-2023 Sentra uses a sealed LED assembly, you won't see a simple 'burnt-out bulb.' Instead, failure presents in a few different ways:
- Partial Failure: One or more individual LEDs in the light strip may stop working, creating dark spots or gaps in the light bar when the brakes are applied.
- Intermittent Operation: The light may flicker, or only work some of the time. This can be caused by a loose internal connection or a failing circuit board within the sealed unit.
- Complete Failure: The entire light strip fails to illuminate when the brake pedal is pressed. While this can mean the assembly has failed, it's also critical to check other potential causes first, like a fuse or the brake pedal switch.
- Dim or Faded Light: Over time, LEDs can lose their intensity. If the light is noticeably dimmer than it used to be, the assembly is nearing the end of its life.
Pro Tip: Before assuming the LED assembly is bad, have a helper press the brakes while you confirm that your main left and right brake lights are working. If NONE of the brake lights work, the problem is more likely the brake pedal switch or a fuse 🎬 Watch: How to troubleshoot fuses and brake light switches, not the CHMSL assembly itself.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
It is important to distinguish between different Sentra generations when discussing brake light issues.
Brake Light Switch Recall (2016-2019 Models ONLY)
Nissan issued a major recall (NHTSA Campaign 21V-135) for over 800,000 Sentras because the brake lights could fail to illuminate. This issue was caused by contamination of the brake light switch located near the pedal. This recall does NOT apply to the 2020-2023 Nissan Sentra. The issue was specific to the design and components used in the previous generation. However, it's a good reminder that a faulty brake switch can cause brake light failure on any vehicle.
2020-2023 Models
As of early 2026, there are no widespread recalls or Technical Service Bulletins (TSBs) specifically targeting the center high mount stop light assembly (part 26590-6LA0A) on the 2020-2023 Nissan Sentra. Most issues appear to be isolated component failures rather than a systemic design flaw.
Buying a Used 2020-2023 Sentra Center Brake Light
Since the CHMSL is a durable LED assembly, a used OEM part is an excellent, cost-effective option. Here’s what to look for when buying a recycled unit:
- Inspect the Lens: Check for any cracks, deep scratches, or hazing on the red plastic lens. A cracked lens can allow moisture to enter, which will quickly destroy the internal electronics.
- Check for Water Intrusion: Look for any signs of fogging or condensation inside the lens. This is a major red flag that the seal has failed and the part should be avoided.
- Examine the Housing and Mounting Points: Ensure the black plastic housing and all mounting tabs are intact and free of cracks. Broken tabs can lead to a loose fit, causing rattles and potential water leaks.
- Verify the Connector: Look at the electrical connector pins. They should be straight, clean, and free of any corrosion.
- Test if Possible: If you have a 12V power source, you can briefly test the unit before purchase to ensure all LEDs illuminate brightly and consistently.
Choosing a used OEM assembly over a cheap aftermarket part often ensures perfect fitment, correct electrical connections, and the same LED brightness and color as the original factory component.
Replacement Overview & Difficulty
Replacing the center high mount stop light assembly is a relatively straightforward job that most DIYers can handle.
- Difficulty: 2 out of 5
- Estimated Time: 0.5 - 1 hour
- Tools Needed: Basic hand tools, plastic trim removal tools.
The general process involves accessing the back of the light from inside the vehicle's cabin. This typically requires carefully removing the rear package tray trim panel located below the rear windshield. 🎬 See how to safely remove the rear package tray trim Once the trim is removed, you will see the mounting nuts and the electrical connector for the light assembly. The process is simply to unplug the connector, remove the nuts, and swap the unit. Using plastic trim tools is highly recommended to avoid scratching or breaking the interior panels.

Frequently Asked Questions (FAQ)
Can I just replace the bulb in my 2021 Sentra's third brake light?
No. The center high mount stop light on the 2020-2023 Nissan Sentra is a sealed LED assembly. There are no user-serviceable bulbs inside. If the light fails, the entire unit must be replaced.
Is my 2022 Sentra part of the big brake light recall?
No. The widely publicized Nissan Sentra brake light recall (NHTSA 21V-135) only covered the 2016-2019 model years. The 2020-2023 models use a different design and are not affected by that specific recall.
Why are only a few of the LEDs in my third brake light working?
This is a common failure mode for LED light assemblies. The individual LEDs are wired in series or series-parallel circuits. A single failed diode or a bad solder joint can cause a section of the light strip to go out while the rest remains lit. This indicates the assembly is failing and needs to be replaced.
Is it illegal to drive with a non-working third brake light?
Yes. The center high mount stop light is a federally mandated safety feature. Driving with one that is not functioning can get you a 'fix-it' ticket and may increase your risk of being rear-ended. It can also cause your vehicle to fail a state safety inspection.
