Mazda CX-5 Problems — All Years, Common Issues & Reliability

The contact owns a 2022 Mazda CX-5. The contact stated that while driving at nighttime at undisclosed speeds, there was an abnormal sound coming from the headlights. No warning lights were illuminated. The vehicle was taken to a local dealer, where it was diagnosed with an unknown headlight fan bearing failure. The vehicle was not repaired because the warranty had expired. The manufacturer was not made aware of the failure. The failure mileage was approximately 37,000.

Sunroof explosion while driving on the interstate and glass shards shot down on us. Sounded like a gunshot by head and it exploded.

Passenger side headlight was making a loud noise. When it began, it happened sporadically, but in ~two weeks, it happened consistently whenever the car was on and could often be heard while driving. The sound was consistent with other reports of the headlight assembly failure and those covered by TSBs for 2019–2023 models. The vehicle was brought to the dealership, the noise was verified as being the headlight failure, and it was replaced under warranty.

The air conditioning compressor clutch suddenly would not engage, leading to reduced visibility out of the windshield during humid weather in Oklahoma springtime and extended times for windshield to defog. Temperatures inside the vehicle also rose to very high levels without air conditioning available, even with windows down while driving. No crash or injuries but this presented an unsafe situation for a vehicle with only 39,000 miles and purchased new from the dealership. There were no indicator lights, messages, or warnings, other than observation that air conditioner vents were no longer blowing cold air when selecting the AC button after problem occurred. Problem was verified by both an independent mechanic and our Mazda dealership. AC system was overcharged from the factory per diagnostic results, leading to internal AC compressor short and early component failure.

Both LED headlights died within two months of each other on this relatively new vehicle. Outside the three year warranty, but only 27,000 miles (well within the 36,000 warranty period). As it's outside of the three years, the warranty already expired regardless of mileage. One headlight was grinding (fan) while the other's low beam simply died. Each headlight cost $2800 to replace. You can't simply replace a burned out bulb with this headlight design. The entire unit must be replaced at a cost of almost $3000 depending on your dealer. This is a major safety issue when headlights die while driving at night. This is not a user maintenance issue. It is not normal wear and tear. Almost $6000 dollars to replace poorly designed headlights within two months of each other on a new-ish vehicle while being a safety concern constitutes reason enough to issue a recall, and to reimburse owners for previous replacements.

The infotainment/CMU system in my 2025 Mazda CX‑5 Carbon Edition has repeated failures that affect safe driving. Wireless Apple CarPlay frequently disconnects, freezes, or causes the screen and controls to stop responding. Navigation and audio alerts lag or fail, and the entire system has gone black once, requiring a hard reset. After one incident where all audio stopped working, I returned immediately to the dealership, and a Mazda service advisor personally witnessed the failure and confirmed no audio output. These unpredictable failures create distraction and uncertainty. As senior drivers, my wife and I rely heavily on stable navigation, audio cues, and hands‑free communication for safe operation. Mazda and Panasonic reviewed the issue but denied CMU replacement, leaving the wireless system unreliable.

While driving on February 12, 2026, the steering system failed, resulting in the steering wheel locking and becoming impossible to turn. While making a right-hand turn, the steering wheel suddenly locked. I had to forcefully jerk the wheel to regain control and avoid colliding with a concrete barrier on the right shoulder. After several seconds, the steering function returned to normal. This failure occurred without warning and created an immediate safety hazard due to loss of steering control. The vehicle has been inspected by a dealership, but the issue could not be replicated and no repairs were performed. This condition presents a serious safety risk as it can occur during normal driving maneuvers and may lead to loss of control and collision.

While driving at various speeds, including highway speeds, the vehicle intermittently fails to slow down when the brake pedal is applied. On multiple occasions, the brake pedal was pressed but the vehicle did not respond appropriately and continued moving forward. On December 1, 2025, while traveling at approximately 65 mph on the interstate in rainy conditions, the vehicle began making a grinding sound and started sliding instead of slowing down. The vehicle briefly lost the ability to decelerate, creating a near-collision with a semi-truck. On December 22, 2025, the issue occurred twice in one day. While attempting to brake at a stop sign and in traffic, the vehicle did not slow down, nearly causing collisions with vehicles in front and adjacent lanes. In the instance where approaching the stop sign where a vehicle was stopped, the dashboard flashed “break” while I was breaking as hard as I could. Warning lights and sensor-related alerts have appeared intermittently prior to and during some incidents. The issue has continued intermittently, including additional incidents where the brakes were either unresponsive or overly sensitive. They do not respond in a consistent or predictable manner, making safe driving nearly impossible. This problem places myself and others at significant risk of collision due to loss of braking control. The vehicle has been taken to multiple dealerships for inspection. The problem has not been successfully replicated, and no repairs have been performed to resolve the issue. Dealership documentation includes customer reports of “NOT BRAKING” and brake malfunction concerns.

The vehicle exhibits unintended acceleration behavior when the brake pedal is applied. Instead of slowing down, the engine revs and the vehicle does not decelerate as expected. On March 16, 2026, while merging onto a highway and applying the brakes, the engine suddenly revved to approximately 3,500 RPMs while the vehicle failed to slow down. There have been previous issues with the vehicle not slowing when breaks are being applied, nut this is the first instance when it was noticed that the RPMs increased while breaking. This issue has also been reported to the dealership, with service documentation noting that when applying the brakes, the engine revs and the vehicle does not slow or accelerate properly. This creates a dangerous condition where braking input does not result in expected deceleration and may instead cause acceleration-related behavior. The issue has not been resolved. This issue significantly increases the risk of collision and loss of vehicle control.

While driving on the freeway, the car stopped having the ability to accelerate. The engine light came on, and I received a notification on the Mazda app stating there was an "engine malfunction." I took it to Mazda, and they told me nothing was wrong. Flash forward a month and the same exact situation occurred. I took it to Mazda, and they told me the same thing. This is incredibly dangerous, as losing the ability to accelerate on a very busy freeway is life-threatening.

RH LED headlight cooling fan failure. Diagnosed by Mazda dealer and quoted 2450 cost. Vehicle is just outside warranty coverage by 2900 miles. This is a very well known and documented problem that Mazda is not standing behind. Owners are removing the relay for their daytime running lights, rendering them inoperable in order to save wear and tear on the headlight cooling fans. This is a safety hazard.

Headlight cooling fan is faulty and causing headlight outage prematurely.
