Is Your Acura MDX Experiencing Signal Problems?
If your turn signals or hazard lights are acting up, a failing hazard warning flasher system is a likely cause. This is a common issue as vehicles age.

Known Issues for 2001-2013 Acura MDX
While no specific recalls or widespread Technical Service Bulletins (TSBs) exist for the hazard flasher system on the 2001-2013 MDX, electrical issues are common in aging vehicles. One specific issue noted for 2010-2013 models is the hazard switch button sticking not because the switch is bad, but because the dashboard panel opening is too tight. Before replacing the switch, check for signs of rubbing inside the dash opening.
For the first generation (2001-2006), the part is often an integrated switch and flasher assembly, while later models may have a separate relay and switch.
Choosing the Right Aftermarket Part
When replacing the hazard flasher or switch, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. For a component like this, a quality aftermarket part can offer significant savings without sacrificing reliability.
- Standard Ignition (SMP): This is a well-regarded aftermarket brand known for producing parts that meet or exceed original equipment specifications. Their switches often feature copper alloy conductors for good electrical performance and are designed as direct-fit replacements. They are a reliable choice for your MDX.
- True Tech: Often positioned as a more budget-friendly option, True Tech is a brand associated with Standard Motor Products. While it may offer cost savings, it's generally considered a step below the main Standard brand in terms of materials and construction. For a critical safety function like hazard lights, sticking with a known entity like Standard Ignition is often the safer bet.

Frequently Asked Questions
Where is the hazard flasher located on my Acura MDX?
For most 2001-2013 MDX models, the flasher relay is located on the back of the fuse box, under the driver's side dashboard near the steering column. The hazard switch itself is the physical button on your center console or dashboard.
🎬 See how to operate the hazard flasher button in this video.Can I replace the hazard flasher myself?
Yes, this is a DIY-friendly job for many owners. Replacing the dash switch typically involves carefully prying off the surrounding trim panel to access the switch. The flasher relay under the dash can be harder to reach but usually just unplugs from the fuse box. The entire process can often be done in under 30 minutes with basic tools.
Why do my turn signals work but my hazards don't (or vice-versa)?
This often points to a faulty hazard switch. The switch has internal contacts that route power for both the turn signals and the hazard lights. If one set of contacts fails, you can lose one function while the other still works.
My turn signals are flashing really fast. Is this the flasher?
A fast-flashing turn signal (hyper-flash) almost always means one of the turn signal bulbs on that side of the vehicle is burned out. The change in electrical resistance causes the flasher relay to blink quickly. Check and replace your bulbs before replacing the flasher relay.
