- Quality aftermarket brands like Beck Arnley and Standard Ignition offer reliable, cost-effective alternatives to OEM parts.
Is It the Switch or the Stopper Pad? A Critical First Step
Recall Alert for 2012-2014 Kia Forte Models
Before you buy a new brake light switch for a 2012, 2013, or 2014 Forte5, check your brake pedal. Kia issued a recall (NHTSA Campaign ID: 17V773, Kia recall SC158) because a small plastic piece called the 'brake pedal stopper pad' can break. This pad is what the brake light switch's plunger presses against. When it crumbles, the plunger goes through the hole, making the car think the brakes are always on. Look for small, broken blue or black plastic bits on your driver-side floor mat. 🎬 Watch: How to fix brake lights that won't turn off. If you find them, your switch is likely fine. A Kia dealer will replace the stopper pad for free under the recall.
Common Symptoms of a Bad Brake Light Switch
For all 2012-2018 models, a failing brake light switch will cause noticeable issues. If you have a 2015-2018 Forte5, these symptoms almost certainly point to a bad switch. If you have a 2012-2014 model and have confirmed the stopper pad is intact, a bad switch is the next logical cause.
- Brake lights don't work: The most dangerous symptom. The switch fails to complete the circuit, and your brake lights never turn on.
- Brake lights stay on: The switch is stuck in the 'on' position, keeping your brake lights illuminated and draining your battery. This can also be caused by the broken stopper pad on 2012-2014 models.
- Cannot shift out of Park: The safety interlock doesn't get the signal that the brake is pressed, so it won't release the shifter. 🎬 See what to do if your Forte is stuck in Park.
- Cruise control won't engage or cuts out: The system gets a false signal that the brakes are being used and will not activate or will shut off unexpectedly.
- ABS or Traction Control light is on: Modern stability systems use brake pedal input to function. A faulty switch can sometimes trigger these warning lights.
Choosing the Right Aftermarket Brake Light Switch
You don't need to buy a genuine Kia part for a simple and reliable fix. Quality aftermarket brands offer excellent value and performance. The key is choosing a brand known for good materials and quality control.
Pro Tip: When replacing the switch, take a picture of the old one's position and how much thread is showing. Try to install the new switch with a similar adjustment before fine-tuning. Proper adjustment is crucial for the switch to work correctly.

- Top Tier (OEM-Equivalent): Brands like Beck Arnley and Standard Ignition (Standard Motor Products) have a strong reputation for sourcing or manufacturing parts that meet or exceed original equipment (OE) specifications. They are a trusted choice for a direct, reliable replacement.

Frequently Asked Questions
Can I replace the brake light switch myself?
Yes, this is a great DIY job for beginners. The switch is located just above the brake pedal. You'll need to disconnect the wire harness, loosen one or two 14mm nuts, and unscrew the old switch. The entire process usually takes less than 30 minutes.
🎬 Watch this quick DIY walkthrough to replace your brake switch.Was there a recall for the brake light switch?
The recall was not for the switch itself, but for the brake pedal stopper pad on 2012-2014 models. This small plastic part failing causes the same symptoms as a bad switch. If you have one of these years, check for the recall (Kia SC158) before buying parts.
How do I know if it's the switch or the stopper pad?
The easiest way is to look on the driver's side floor mat for small, broken pieces of hard plastic, which are often blue or black. If you find these, the stopper pad has failed. If the floor is clean and you have a 2012-2014 model, you can also press the brake pedal and visually inspect the area where the switch plunger makes contact. If you see an empty hole instead of a solid surface, the stopper is gone.
Does the new switch need to be adjusted?
Yes, proper adjustment is critical. The switch needs to be threaded in just enough so that the plunger is fully depressed when the brake pedal is not touched, but is immediately released as soon as you press the pedal. After installing, have a friend confirm your brake lights turn on and off correctly with the pedal movement.
