Is Your Buick Regal Hard to Start? It Could Be the Ignition Switch.
If your 2011-2017 Buick Regal has trouble starting, stalls unexpectedly, or has flickering dashboard lights, a failing ignition switch is a likely suspect. This part is used every time you drive, so it can wear out over time. Understanding the symptoms and your replacement options can help you get your car back on the road reliably.
Symptoms of a Failing Ignition Switch
A bad ignition switch can cause a range of confusing problems. Here are the most common signs to watch for:
- No-Crank, No-Start: You turn the key, and nothing happens. The engine doesn't even try to turn over. 🎬 Watch this video to troubleshoot a no-crank, no-start condition. This can mean the switch isn't sending power to the starter circuit.
- Starts and Immediately Stalls: The engine fires up but dies as soon as you let go of the key. This suggests the switch is failing to keep power flowing to the ignition system in the 'On' position.
- Intermittent Electrical Problems: Your radio, power windows, or dashboard lights may cut out randomly while driving or only work in certain key positions.
- Key is Hard to Turn or Gets Stuck: While this can also be a lock cylinder issue, a problem inside the switch can make it difficult to turn the key.
- Car Stalls While Driving: This is a serious safety issue. A faulty switch can lose connection over a bump, cutting all power to the engine. 🎬 See common causes and solutions for Buick Regal stalling issues.
Was This Regal Part of the GM Ignition Recall?
While there were major GM recalls for ignition switches, the main recall for defective switches primarily affected older models like the Chevy Cobalt and 2004-2005 Buick Regal. The 2011-2017 Buick Regal was not part of that specific, large-scale ignition switch recall. However, some 2011 Regals were recalled for an issue where the key could be removed when not in Park (NHTSA 16V502000) and for a separate wiring issue under the power seats (NHTSA 16V517000), which could cause electrical problems. Always verify any open recalls for your specific vehicle using its VIN on the NHTSA website.
Choosing the Right Aftermarket Ignition Switch
When replacing your ignition switch, you have several good aftermarket options. Since the OEM part can be pricey, a quality aftermarket brand offers a reliable repair at a better value.
- ACDelco: As GM's official parts brand, ACDelco is the closest you can get to the original factory part. They offer OE-spec parts that are a direct fit and are known for quality and reliability. This is a trusted, safe choice for any repair.
- Standard Ignition (Standard Motor Products): A highly respected name in the aftermarket, Standard has a reputation for producing parts that meet or exceed OEM quality. Technicians often trust Standard for electronic components due to their consistent performance and durability.
- Rostra Powertrain: Rostra is a US-based manufacturer known for producing quality electronic components and holding high-level quality certifications (ISO-9001 and IATF-16949). They are a solid choice, often providing good quality at a competitive price.

Pro Tip: Check the Lock Cylinder First
Before replacing the switch, make sure your problem isn't the ignition lock cylinder—the mechanical part the key fits into. If your only symptom is the key being physically stuck or hard to turn, the lock cylinder might be the issue, not the electronic switch. Replacing the wrong part won't solve the problem.
Frequently Asked Questions
Do I need to reprogram my key after replacing the ignition switch?
No. The ignition switch is a separate electronic component. Your key's security chip is read by the ignition lock cylinder and the car's immobilizer system. Replacing only the switch does not require key reprogramming.
Is the ignition switch the same as the ignition lock cylinder?
No. The lock cylinder is the mechanical tumbler assembly that your key physically turns. The ignition switch is the electronic part connected to it that sends power to the vehicle's systems. They are two distinct parts that can be replaced separately.
Can I drive my Regal with a bad ignition switch?
It is not recommended. If the switch is failing, it could cause the engine to stall while driving, leading to a loss of power steering and brakes, which is extremely dangerous. It's best to get it repaired as soon as possible.
Is replacing the ignition switch a DIY job?
For a moderately skilled DIYer, yes. The job typically involves removing the plastic shrouds around the steering column to access the switch. It requires basic hand tools, but some models may have security bolts (reverse Torx) that require a special socket. If you are not comfortable working around steering column components, it is best to leave this job to a professional.
