MAZDA Complaints

On four different occasions, the most recent being last night (1/9/2025), the vehicle has suddenly lost drive power while driving. The ability to accelerate is suddenly gone. When you press the gas pedal the engine revs, as if it is in neutral, but it does not accelerate. When this happens, the vehicle is still in drive as indicated by light on the shifter showing drive and the fact the vehicle, just moments before, is driving. During all four instances, I had to bring the vehicle to a complete, put the car in park and then back into drive. On three of these occasions there was no pull-out lane and I had to bring the vehicle to a complete stop in a moving lane of traffic. The incident last night occurred mere seconds after making a left-hand turn with traffic coming up behind me at a higher speed then I was travelling. My safety, the safety all passengers in my car and the safety of other drivers are all at risk when this occurs. When this happens there are no warning lamps or messages that appear. After the third time it happened (on 12/6/2024), we took the vehicle to the Mazda dealership we leased it from and it was inspected and we were told they found nothing wrong with it. They noted they did some updates. They kept the vehicle from Monday 12/9 - Thursday 12/12. Less than a month after getting the vehicle back from the dealership this issue occurred a 4th time (on 1/9/2025 at about 8pm). We will be calling the dealership this morning and setting up an appointment for them to again inspect the vehicle for this safety concern. Our vehicle is available for inspection upon request.

Car was purchased in June 2019. Car started smelling like burning oil and started finding oil pooling under the car around November 2024. At time the incident was discovered, car only had 38k miles. There was no warning lights or indication there was an issue other than the smell and small pool of oil under car. The Mazda service manager immediately knew what the issue was and told me they were going to confirm with a full inspection and diagnosis. I was told that I have a cracked cylinder head and I will need to have it replaced. Warranty ended few months prior so they will not cover. I was told it would cost $4589.76. The Mazda service department told me that this is a common issue and to hold off on repair and contact Mazda corporate since warranty just ended. They topped off my oil and told me to keep an eye on the oil level and to wait to hear back from Mazda corporate.I submitted a case with Mazda and the customer care specialist told me that they cannot guarantee they will cover this. Within a week, the temperatures got colder and issue got worse. Low oil light came on, topped off with oil. Lost 4 quarts in one day. Called Mazda service and they told me to top off oil and come drop car off immediately. Upon researching this issue, the cracking of cylinder heads in Mazda CX-5 vehicles, particularly those with the 2.5-liter (NA) engine were widespread and discussed in online forum. The contributing factors of the issue point to a design flaw of the cylinder head due to the cylinder deactivation technology and a manufacturing defect due to the cylinder head casting process based on reports and discussions within the automotive community. A TSB (SA-013/22) has been released for the affected cylinder head with a modified replacement. This seems to be a significant and widespread issue that can cause entire engine to fail and require full replacement. Oil leaking on to the hot exhaust near other engine parts could ignite and put myself or others at risk.

Engine block cracked, passenger cabin filled with noxious odder. Vehicle was suddenly leaking oil at high rate.

At approximately 57,000 miles, the cylinder head cracked. It was leaking oil and white smoke was coming out of the engine bay. There were no warning lights. I have since gotten the cylinder head replaced.

Coolant leaks at the cylinder head around the exhaust manifold causing my car to over heat. Also when my thermostat is set to the exact temperature for both sides my driver side blows cold and the passenger side blows hot

Ticking sound coming from engine. Likely related to the hydraulic lash adjusters. Vehicle has had a recent oil change by a technician.

Car engine shut down and slowly came to a full stop on the highway on 1/4/25, putting myself and my daughter of being rear ended at full speed on a highway where the speed limit is 65mph. The steering wheel locked and I was unable to move the car to any shoulder. I put the car in park and pressed the start ignition button to start the car and was able to drive again. An appointment is scheduled for 1/17/25 for diagnostics at a Mazda dealership. There were no warning messages prior to this event.. My battery was replaced 2 weeks prior to this incident.

I was driving on a city street and slowed to turn right onto a driveway at at a private residence. As my car entered the driveway and near the end of the right turn, my car had a sudden unintended uncontrolled acceleration, continued the turn, went over a low hedge of shrubs on the right side of the driveway, continued down a short rocky incline, and landed on a large rock where the car stopped.

My car has less than 65,000 and is just 10 years old but the transmission cross member is shot .I have had cars with nearly 300,000 and this never happened the part is on backorder.

The contact owns a 2023 Mazda CX-5. The contact stated that while the temperature was 45 degrees or lower, the vehicle failed to start properly, and the engine failed to warm up properly. The coolant light was illuminated, and the engine temperature gauge failed to rise above COLD. The vehicle occasionally failed to start or while started and driving at various speeds, the vehicle stalled while and engine temperature failed to reach the normal operating temperature. The check engine light was illuminated. The contact would shift to SPORT Mode to prevent the cylinder activation from occurring and causing the vehicle to stall.

Additionally, the key fob intermittently failed to unlock the vehicle. The contact stated that the vehicle failed to start and had to be towed.
