The brakes have been faulty since I've purchased the vehicle new. There is a loud scream that is not from dust or wear. There is a manufacturing defect in the brakes. The brakes are very loud every time I apply them. I am very concerned about this, have contacted the company before.

What stands out
Of the 10 model years of Mazda CX-5 we track for brakes problems, this one carries the most owner complaints on file — 52.
Owners have filed 52 brakes complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: The 2016 Mazda CX-5 has widespread, documented brake system issues affecting both the electronic parking brake (EPB) control module and the rear brake calipers. Owners report failures as early as 5,000 miles, including EPB module shorts ($765–$900 to replace), rear caliper sticking and dragging (causing overheating and premature pad/rotor wear), and uneven pad wear requiring brake service twice in short intervals. Mazda issued technical service bulletins acknowledging the defects but refuses to issue a recall or cover repairs outside narrow VIN/build-date windows, leaving owners with costly out-of-pocket repairs.
The 2016 CX-5 shows a pattern of early brake system failures across two main areas: the electronic parking brake (EPB) control module and the rear brake calipers.
EPB Control Module failures occur as early as 5,000 miles. Owners report the module shorting, failing to disengage, or self-engaging without warning. The parking brake light flashes on the dash and control lever; the red brake warning light stays lit. A few owners had the module engage unexpectedly while driving, creating a traffic hazard. Dealer diagnostics confirm module failure; replacement costs $765–$900. Mazda issued TSB 04-005/16 for vehicles with VINs below 781350, but refuses to cover repairs outside that window or after warranty expiration.
Rear caliper sticking causes brakes to overheat, overpressurize, and wear unevenly. Outer brake pads wear down to the backing plate (3–8 mm) while inner pads remain mostly unworn (5–6 mm). Rotors scorch and score. Owners smell burning brakes, see smoke, and experience wheel temperatures exceeding 400 degrees Fahrenheit. The issue repeats even after brake service; one owner replaced rear pads and rotors twice in one year. Caliper failure often goes undetected until catastrophic wear occurs.
Brake pad wear at low mileage is severe and uneven. Owners report pads worn to backing plate or near-metal at 6,000–22,000 miles. Dealers claim normal wear and deny warranty coverage. Multiple TSBs (04-005/15, 04-005/16, 04-004/19, 04-005/20) document the issue and recommend caliper replacement, but Mazda limits eligibility by VIN and build date, refusing to cover 2016 models uniformly.
Failure modes owners describe
Electric Parking Brake (EPB) Control Module Failure
EPB control module shorts out, fails to disengage, or self-engages without driver input. Module requires replacement at dealer cost. Affects vehicles with VINs below 781350 per TSB 04-005/16. Owners report the module failing intermittently or completely, with warning lights flashing on dash and control lever. Some report the parking brake engaging at speed, creating traffic hazard.
When: At low mileage: 12,000–21,000 miles reported most frequently; some failures as early as 5,000 miles.
Symptoms owners cite: EPB warning light flashing on dashboard and control lever; Red brake warning light illuminated; Parking brake fails to disengage after multiple restarts; Parking brake engages unexpectedly while driving; EPB engages on startup, disengages after restarts or after extended wait (30+ minutes); No warning before failure occurs
Codes mentioned: TSB 04-005/16 (08/05/2016), TSB R052/16C
Repairs/costs cited: EPB control module replacement: $765–$900+ at dealer. Owners report paying out of pocket after warranty expiration. One owner paid $140 for diagnostic alone.
Recalls/TSBs owners mention: TSB 04-005/16 issued for VINs below 781350. Mazda acknowledged the issue in service bulletins but did not issue a recall. Some dealers have replaced modules under warranty; others refuse if vehicle is out of warranty or if VIN is outside TSB range. Corporate declined to cover collateral damage (worn pads/rotors) caused by the module failure.
Rear Brake Caliper Sticking and Dragging
Rear calipers (driver-side or passenger-side) stick, seize, or fail to release fully, causing brake drag, excessive heat, and premature pad/rotor wear. Owners report uneven pad wear (outer pad heavily worn, inner pad minimal wear). Caliper failure often undetected until brakes overheat or pads wear to backing plate. Some calipers lock up during use, creating safety hazard. TSB R052/16C documents production change in rear calipers starting September 9, 2016, but Mazda will not retroactively cover older calipers.
When: Between 5,000 and 40,000 miles; one case at 15,000 miles on a 400-mile trip; recurring issue even after replacement at ~20,000 miles; one failure at 42,000 miles.
Symptoms owners cite: Rear brakes overheat; visible smoke or smell of burning brakes; Uneven brake pad wear (outer pad 3–8 mm worn, inner pad 5–6 mm or minimal); Brake rotors scorched, scored, or showing heat damage and corrosion; Grinding or squeaking from rear brakes; Rear wheel hot to touch (over 400 degrees Fahrenheit in one case); Vehicle shakes or vibrates in rear when brakes engaged; Brake pads wear to backing plate after short interval; No warning lights or symptoms before failure detected
Codes mentioned: TSB R052/16C, TSB 04-005/16, TSB 04-004/19, TSB 04-005/20, TSB 04-005/15 (though officially limited to 2013–2014 models)
Repairs/costs cited: Caliper replacement: $500 for one brake job (pads and rotors). Owners report needing brake service twice within 8,000–20,000 miles of the first service. Parts on backorder at dealerships. One owner replaced rear pads and rotors twice in one year at ~20,000 miles.
Recalls/TSBs owners mention: TSB R052/16C issued documenting defective rear calipers in early production 2016 CX-5s; production change made September 9, 2016. Mazda refuses to acknowledge defect for vehicles built before that date or to proactively replace both calipers when one fails. Dealers claim the issue is normal wear or environmental (salt corrosion), not a defect. Warranty coverage denied when vehicle exceeds mileage or age thresholds.
Excessive and Uneven Rear Brake Pad Wear
Rear brake pads wear prematurely and unevenly, especially at low mileage (under 30,000 miles). Outer pads wear much faster than inner pads, or one side (driver or passenger) wears significantly more. Wear often occurs despite owner performing normal maintenance and light driving. Rotors become scored or corroded. Owners cite TSBs (04-005/15, 04-005/16, 04-004/19, 04-005/20) that document the issue and propose caliper replacement as the fix.
When: As early as 6,379 miles; common at 12,000–22,000 miles; one case at 31,234 miles; another at 42,000 miles.
Symptoms owners cite: Brake pads worn to backing plate or near it (3–8 mm vs. normal 8+ mm); Uneven pad wear (outer pad much thinner than inner, or one side much worse than other); Rotors visibly scored, corroded, or showing heat marks; Grinding or squeaking noise from rear brakes; Brake warning light illuminated; Braking feels mushy or requires hard pedal pressure; Brake pedal must be deeply pressed to achieve deceleration
Codes mentioned: TSB 04-005/15, TSB 04-005/16-3217, TSB 04-004/19, TSB 04-005/20, NHTSA #10092486
Repairs/costs cited: Pad and rotor replacement: dealers quote $600 for complete brake job. Owners report needing service as early as 12,000 miles and again within 8,000 miles of first service. One owner's rear pads and rotors needed replacement twice in one year. Dealers claim normal wear and tear; not covered by warranty. Independent mechanics found the issue unusual and cited the TSBs.
Recalls/TSBs owners mention: Multiple TSBs issued (04-005/15, 04-005/16, 04-004/19, 04-005/20) recommending caliper replacement as the solution. TSB 04-005/15 covers 2013–2014 models built before October 9, 2013, and offers extended warranty. Mazda refuses to apply the TSB to 2016 models or to VINs outside the specified build dates. Dealers will not honor the TSB repair for out-of-warranty or ineligible vehicles.
Unexpected Unintended Acceleration
Vehicle accelerates suddenly without driver input while braking at low speed (parking lot, stop sign). Owners apply brake to stop, but car lurches forward or jumps curb instead. One incident caused collision with building. No warning lights or indication of imminent failure. Owners fear the issue will recur in traffic, endangering themselves and others.
When: At low speeds (10–25 mph, parking lot approach); one report on first day of winter/snow driving.
Symptoms owners cite: Sudden acceleration while applying brake; Vehicle lurches forward despite brake pressure; No control over vehicle until shifted to neutral or impact occurs; Happens when brake is depressed fully; No warning lights or symptoms before the event
Repairs/costs cited: No repair information provided by owners; vehicles remained unrepaired.
Recalls/TSBs owners mention: None documented. Owner filed NHTSA complaint and requested help; no dealer or manufacturer response noted.
Loss of Braking Force in Cold Weather
First brake application of the day in winter conditions (near freezing or below) produces little or no stopping force. Vehicle rolls 3–5 feet even with brake pedal pressed to floor. Occurred multiple times within 20 minutes on first snowy day. Did not occur during prior winter season. Owner unsure of cause.
When: December, first snow day; temperatures –4 to 14 degrees Fahrenheit (–20 to –10 degrees Celsius).
Symptoms owners cite: Brake pedal depressed to floor with no immediate stopping; Vehicle rolls 3–5 feet before braking takes effect; Occurs on first brake application after starting car; Repeats within short time window (20 minutes); Did not occur in prior winter
Repairs/costs cited: No repair documented; issue occurred but not taken to dealer for diagnosis.
Recalls/TSBs owners mention: None documented.
Brake Pedal Kickback and Resistance
Brake pedal resists driver input or kicks back, especially in hard braking situations. Pedal feels as though it is resisting the driver's effort to stop. In one case, driver had to shift to neutral to stop the vehicle. In another, pedal kicked back when driver applied hard braking in traffic to avoid collision.
When: During traffic braking situations; one incident during hard stop at traffic light.
Symptoms owners cite: Brake pedal resistance or kickback when pressed; Pedal does not respond normally to pressure; Brakes appear to lock up or resist rather than engage smoothly
Repairs/costs cited: No repair information provided.
Recalls/TSBs owners mention: None documented.
Brake Noise (Grinding, Squeaking, Jerking)
Audible grinding, squeaking, or jerking sounds from brakes during normal driving or braking. Sounds persist after dealer service and pad replacement. One owner reports jerking sound when decelerating from 40 mph or leaving freeway ramp; another reports screaming sound from day of purchase.
When: From new (one case); also at 32,000–40,000 miles and recurring after service.
Symptoms owners cite: Grinding or squeaking sound from rear brakes; Loud scream or screech when braking; Jerking sensation during deceleration; Noise persists after dealer service; Noise more prominent at specific speeds (40 mph deceleration)
Repairs/costs cited: Dealers replaced pads; noise persisted. One mechanic suspected ball bearings or worn pads. No definitive repair documented.
Recalls/TSBs owners mention: None documented. Dealers unable to resolve issue despite multiple visits.
Brake Warning Light and Brake System Malfunction Lights
Red brake warning light or 'Smart Brake Malfunction' message illuminates and remains on continuously or intermittently. Lights blink or stay lit even when brakes function normally. One owner reports both brake light and emergency brake light blinking constantly for over a year. Lights remain on after brakes are serviced. Distraction and safety concern.
When: Can occur from early in vehicle life or after service; one case reports lights on for at least one year continuously.
Symptoms owners cite: Red brake warning light illuminated on dash; Smart Brake Malfunction message displayed; Lights blink constantly while engine running; Lights remain on after brake service; Brake lights remain lit even after brake component replacement; No obvious brake malfunction detected by dealer
Repairs/costs cited: Owners unsure; dealers unable to resolve in some cases. One owner avoided repair due to cost ($900+ EPB module).
Recalls/TSBs owners mention: Mazda customer service stated that if dealer cannot detect an issue, they cannot help. Dealers blame 'normal wear and tear' or refuse to diagnose further.

Our 2016 Mazda cx-5 has 16,000 miles on it and the rear brakes have completely deteriorated. After visiting the dealership, I was told the brakes have rusted out due to the use of the parking break (we need to use the parking break due to where we park). Mazda claims this is a normal 'wear-and-year' issue but I do not see how this is as the vehicle has such low mileage. The 2013-2015 cx-5s…
Excessive rear brake wear. Rear pads worn down to metal backing plate at 20,900 miles with no audible break wear indicator. Front brakes 70% worn at same milage.
In august 2016, I bought a brand new 2016 Mazda cx-5 (dealership: wellesley Mazda). Unfortunately, the car had issues related to my brakes. On december 08, 2017, the brakes of my right rear tire locked up while I was driving in a city street (35mph zone) causing them to overheat to the point where the brake disc got red hot and smoked up, increasing the risk of my tires blowing out/catching fire…
