Common Failure Symptoms:
- Engine Won't Crank or Start: You turn the key and hear a single click, a buzz, or nothing at all.
- Intermittent Starting: The car takes several tries to start. You might find yourself holding the key in the 'START' position for a few seconds before the engine turns over.
- Engine Stalls While Driving: This is a critical safety issue. The switch can momentarily lose its connection, causing the engine to die unexpectedly, sometimes after hitting a bump. The car can often be restarted immediately after.

- Flickering Accessories: The radio, dashboard lights, or power windows may cut out or act strangely as the switch fails to provide consistent power.
No Active Recalls for the TSX Ignition Switch
While Honda/Acura did issue recalls for ignition switches on earlier models from the late 1990s and early 2000s, the 2004-2014 Acura TSX was not included in these campaigns. The issues seen in the TSX are typically due to normal wear and tear over many years and miles, not a specific manufacturing defect covered by a recall.
Choosing the Right Aftermarket Ignition Switch
When replacing your ignition switch, you have the choice between an original equipment (OEM) part from the dealer and an aftermarket part. For this specific component, an aftermarket switch offers significant savings and is a very practical choice. The part itself is a relatively simple electrical switch, and reputable aftermarket brands produce quality replacements that meet or exceed original specifications.
Brand Quality Tiers
- Premium Aftermarket (Beck Arnley, Standard Ignition): These brands are well-known for producing parts that closely match original equipment form, fit, and function. They often use high-quality materials like corrosion-resistant contacts and are a reliable choice for a long-lasting repair.
- Standard Aftermarket (Rostra Powertrain, True Tech): These brands provide a functional and cost-effective solution. They are a good option for budget-conscious repairs and will restore the vehicle's function effectively.
Pro Tip: The part you need to replace is just the electrical switch, not the entire lock cylinder assembly. This means you will reuse your original keys and the mechanical lock, so no expensive key reprogramming is necessary.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $26 - $84 |
| New OEM (Dealer) | $90 - $135 |
| Shop Labor | $160 - $235 |
Frequently Asked Questions (FAQ)
Can I drive my TSX with a bad ignition switch?
It is not recommended. The most dangerous symptom is the engine stalling while driving, which can lead to a crash. It's best to get the vehicle repaired as soon as possible.
Is replacing the ignition switch a DIY job?
Yes, for those comfortable with basic tools and working in tight spaces. The job involves removing the plastic covers around the steering column, unplugging a wiring harness, and removing two small screws. 🎬 Watch this walkthrough for replacing the switch on a 2004 TSX The most difficult part is the awkward access to the screws.
Do I need to reprogram my keys after replacing the switch?
No. You are only replacing the electronic switch portion. The mechanical lock cylinder and the immobilizer system that reads your key remain in the car, so no reprogramming is needed.
How do I know if it's the ignition switch or the starter?
A buzzing sound from the dash strongly points to the ignition switch. If you hear a single, solid 'click' from the engine bay when you turn the key, the problem is more likely the starter. If you have flickering dash lights or intermittent stalling, the ignition switch is the more probable cause.
