If your Altima won't start or the brake lights are acting up, the brake light switch is the likely cause.
- A faulty brake light switch is a primary cause for 2007-2018 Altimas that won't start.
- Symptoms include brake lights stuck on/off, inability to shift from Park, and ABS/TCS warning lights.
- This is a known issue acknowledged by Nissan through Technical Service Bulletins (TSBs).
- Replacement is extremely easy, requires no tools, and can be done in minutes, making it a great DIY fix.
Is a Bad Brake Light Switch Causing Your Altima's Problems?
A failing brake light switch on a 2007-2018 Nissan Altima is a common issue that can cause a surprising number of problems. Because the switch is tied into multiple vehicle systems, its failure can mimic other, more serious issues. Understanding the symptoms can save you from a frustrating misdiagnosis.
🎬 Watch this video to identify common bad brake light switch symptoms.Key Failure Symptoms
- Car Won't Start: On models with a push-button ignition, a bad switch won't tell the computer the brake is depressed, preventing the engine from starting.
- Brake Lights Don't Work: The most obvious symptom is that your brake lights don't illuminate when you press the pedal, which is a serious safety hazard.
- Brake Lights Stay On: The switch can fail in the 'on' position, leaving your brake lights illuminated even when the car is off, draining the battery.
- Can't Shift Out of Park: The safety interlock that prevents you from shifting out of Park without pressing the brake relies on the switch's signal.
- Warning Lights: A faulty switch can trigger the ABS or traction control warning lights on your dashboard.
A Known Nissan Issue: TSB NTB15-111
For 2013-2015 Altima models, Nissan issued Technical Service Bulletin NTB15-111 for issues where the stop lamps stay on and the vehicle has low power during acceleration. This was often caused by a failing stop lamp relay, which was stressed by a faulty switch. The official fix involves removing the relay, bypassing the circuit, and installing a new, updated brake light switch. While this TSB is specific to those years, the underlying problem of switch failure is common across the entire 2007-2018 generation.
Choosing the Right Aftermarket Brake Light Switch
When replacing the brake light switch, you don't need to buy an expensive OEM part from the dealer. Aftermarket brands offer excellent quality, often at a much lower price. Here’s a breakdown of available brands to help you choose.
- Premium Quality (OEM Equivalent): Brands like Beck Arnley and Standard Ignition (SMP) focus on meeting or exceeding original equipment specifications. They are known for reliable fit and function and are a top choice for a long-lasting repair.
- Reliable Value (Mid-Tier): Dorman and Holstein offer a great balance of price and quality. Dorman, in particular, is known for its "OE Solutions" line, which often re-engineers parts to fix common factory flaws. While general Dorman quality can be hit-or-miss depending on the part, for common components like this, they are a solid choice. 🎬 Learn more about Dorman replacement parts for your Altima repair.
- Economy (Budget-Friendly): Brands like Replacement, True Tech, and URO Parts provide a low-cost alternative. These are a viable option if budget is the primary concern, but they may not offer the same long-term durability as higher-tiered brands.
Pro Tip: The brake light switch is a very simple part to replace yourself, often requiring no tools. Given the low cost of even premium aftermarket parts and the ease of installation, it makes sense to choose a quality brand like Standard Ignition or Beck Arnley to avoid repeating the job.

🎬 See how to replace the brake light switch yourself in minutes.Why won't my Altima start even though the battery is good?
For push-button start models, a failed brake light switch is a very common cause. The car's computer requires a signal from the switch to confirm the brake is pressed before it will allow the engine to start. Without this signal, nothing will happen when you press the start button.
My brake lights are stuck on and draining my battery. Is it the switch?
Almost certainly. When the switch fails or the small plastic stopper on the pedal arm breaks, it can cause the switch to remain in the 'on' position, leaving the brake lights on constantly and draining the battery. This was a widespread issue covered by a Nissan TSB for 2013-2015 models.
Was there a recall for the brake light switch on my Altima?
While there were recalls and TSBs for brake switch issues on various Nissan models (including some Altimas outside the 2007-2018 range and other models like the Pathfinder), there wasn't a single, all-encompassing recall for every 2007-2018 Altima. However, the high failure rate and related service bulletins confirm it is a well-known problem.
