Acura CL Ignition Switch Guide: Understanding Failures and Replacement (1997-2003)
If your Acura CL is stalling or won't start, the ignition switch is a likely and well-documented culprit.
- Engine stalling while driving is the number one symptom and a major safety risk.
- This part was subject to a massive safety recall; even recall-replaced parts can fail again after 20+ years.
- The replacement is a straightforward DIY job that does not require key reprogramming.
- Avoid used parts; new aftermarket switches from brands like Standard or Beck Arnley are reliable and affordable.
Symptoms of a Failing Acura CL Ignition Switch
A bad ignition switch in the 1997-2003 Acura CL has very distinct and often dangerous symptoms. Due to premature wear on the internal electrical contacts, the connection can become intermittent. 🎬 Watch: How to test for a failing ignition switch This can happen suddenly and without much warning.
- Engine Stalls While Driving: This is the most critical symptom. The engine may shut off without warning while you are driving, including at highway speeds. All dashboard lights may illuminate as if you just turned the key, and you will lose power steering and power brakes. In many cases, the car can be restarted after pulling over.
- Car Won't Start or Starts Intermittently: You may turn the key and get nothing, or the car may only start after several attempts. Sometimes, the engine will start but die immediately.
- Electrical Problems: Accessories like the radio or air conditioning may not work correctly or may cut out. In some cases, owners have reported other electrical issues mysteriously resolving after the ignition switch was replaced.
- Key is Hard to Turn: While less common for this specific failure, a binding or difficult-to-turn key can sometimes be related to the switch assembly behind the lock cylinder.
A Note on Safety Recalls
Honda issued major recalls for the ignition switch on the 1997-1999 Acura CL (NHTSA Campaign ID: 02V120000) and later models due to the risk of engine stalling. Another recall addressed the key being removable without the transmission in Park (NHTSA ID: 03V423000). Even if a recall was performed years ago, the replacement parts can still fail after two decades of use. Do not assume your switch is fine simply because a recall was done in the past.
Choosing the Right Aftermarket Ignition Switch
When replacing a critical safety part like the ignition switch, quality matters. You are replacing the electrical component only, not the lock cylinder, so you will continue to use your original keys. Here’s a breakdown of available aftermarket brand quality.
Pro Tip: Given the history of failures, avoid used or junkyard ignition switches for this vehicle. The low cost of a new aftermarket part outweighs the risk of using a pre-owned component with unknown history.
Tier 1: Premium Aftermarket
Standard Ignition (Standard Motor Products) & Beck Arnley: These brands are well-regarded in the industry for producing parts that meet or exceed OEM specifications. Standard Motor Products manufactures their components with robust materials and performs 100% testing. Beck Arnley focuses on matching the form, fit, and function of the original part, often using corrosion-resistant contacts. For a part this critical, spending a little more on one of these brands is a wise investment.
Tier 2: Standard Replacement
Rostra Powertrain & Replacement: These brands offer a functional and cost-effective solution. A 'Replacement' branded part is a generic or house brand that provides a direct fit at a lower price point. While they will get the job done, they may not feature the same level of over-engineering or premium materials as the top-tier brands.

Frequently Asked Questions
Is this a difficult repair to do myself?
For a moderately experienced DIYer, this is a very manageable job. It typically takes about an hour and requires basic hand tools. The process involves removing the plastic shrouds around the steering column, unplugging the old switch, unscrewing it from the lock cylinder housing, and installing the new one. No special tools are required.
🎬 See this step-by-step walkthrough for replacing the switchWill I need to get my keys reprogrammed?
No. You are only replacing the electrical switch on the back of the ignition assembly. The mechanical lock cylinder and your original keys are not being changed, so no reprogramming is necessary.
My car was part of the recall. Why did the part fail again?
The original recalls happened nearly two decades ago. While the replacement parts were an improved design, they can still wear out and fail after many years and miles. It is a common occurrence for owners to replace the switch for a second time on these high-mileage vehicles.
What's the difference between the ignition switch and the lock cylinder?
The lock cylinder is the mechanical part you put your key into. The ignition switch is the electronic part attached to the back of the cylinder that actually sends power to the car's systems. The common failure on the Acura CL is with the electrical switch, not the mechanical lock.
