Brake System Warning Light on a Infiniti Q70
Stop safely as soon as possible. Continuing to drive risks serious damage or a safety hazard.
What the Brake System Warning Light Means on a Infiniti Q70
On the Infiniti Q70, the red brake light means the system has detected something wrong with your primary brakes — low fluid, a leak, or worn components pulling fluid level down. Unlike the ABS light, this one can affect your ability to stop.
How Urgent Is the Brake System Warning Light?
Urgency level for this indicator on the Infiniti Q70: critical. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Brake System Warning Light appeared, how the Infiniti Q70 is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
Common Symptoms Alongside the Brake System Warning Light
The Brake System Warning Light on your Infiniti Q70 is one data point, and the symptoms around it are the rest of the story. Perhaps the engine feels different, a gauge reads unusually, or the car behaves normally but the symbol simply will not clear. Note everything you observe, because the pattern of symptoms on the Infiniti Q70 is exactly what turns a vague warning into a specific, fixable diagnosis.
- Red BRAKE symbol illuminated
- Soft, spongy or sinking brake pedal
- Brake fluid low in the reservoir
- Longer stopping distances
- Sometimes lit with the handbrake released
What Causes the Brake System Warning Light to Come On?
There is rarely a single universal reason the Brake System Warning Light appears on a Infiniti Q70; instead there is a shortlist of usual suspects. Root causes range from simple, inexpensive items to genuine component failures, which is why a proper diagnosis always beats guessing. Understanding the common triggers on the Infiniti Q70 helps you have a more informed conversation with your mechanic and avoid paying for parts you do not need.
- Low brake fluid level
- A hydraulic fluid leak
- Worn brake pads dropping fluid level
- Faulty brake fluid level sensor
- Parking brake not fully released
How to Fix the Brake System Warning Light on a Infiniti Q70
Fixing the Brake System Warning Light on a Infiniti Q70 is methodical, not mysterious. Start with the quick, no-cost checks, then let the vehicle's own trouble codes guide you toward the specific system at fault. The ordered steps here are designed so that by the time you (or your technician) reach the more involved work, you have already eliminated the easy explanations.
- Confirm the parking brake is fully off
- Check the brake fluid reservoir level immediately
- If the pedal feels soft or fluid is low, do not drive — arrange recovery
- Look under the car for fluid leaks at the wheels
- Have the brake system inspected and bled by a technician
Is It Safe to Drive With the Brake System Warning Light On?
Whether it is safe to keep driving your Infiniti Q70 with the Brake System Warning Light on comes down to urgency (critical) and behaviour. As a rule, if the light is red or flashing, or the Infiniti Q70 is running poorly, stop somewhere safe and arrange help rather than pushing on. If the light is amber and the car drives normally, you generally have time to reach a workshop — but 'have time' is not the same as 'ignore it', so book a check promptly.

Professional Mechanic Tips
Low fluid is often just worn pads pulling the level down; top up only with the correct DOT spec and get the pads measured.
If the brake pedal on a Infiniti Q70 goes soft or sinks to the floor with this light on, stop driving — that is a hydraulic failure, not a sensor glitch.
Frequently Asked Questions
Why is the Brake System Warning Light on in my Infiniti Q70?
Your Infiniti Q70 turned on the Brake System Warning Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Brake System Warning Light on?
It depends on the urgency (critical) and how your Infiniti Q70 is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
How much does it cost to fix the Brake System Warning Light on a Infiniti Q70?
Repair cost for the Brake System Warning Light on your Infiniti Q70 depends entirely on the root cause. Because the same symbol covers cheap and expensive faults alike, a proper scan-based diagnosis is the best money you can spend — it turns a guess into a precise, fair quote.
Will the Brake System Warning Light reset itself on a Infiniti Q70?
Occasionally, yes — a Infiniti Q70 can extinguish the Brake System Warning Light by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
