| Apr 2025 | ENGINE | No codes, dealer unable to duplicate. I have been hearing a lifter tick come and go for months (since February ) with my oil level up to par. The ticking gets louder and then quieter. | Crash: No Fire: No | Unknown |
| Jan 2025 | STEERING,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Dec 2024 | ENGINE | Check engine oil light came on after only 2K miles from last oil change. Upon inspection there was practically no oil in my engine!!! I see there is an ongoing issue since 10/21 with 2021 Mazda CX-5 turbo engines. Despite Mazda’s awareness of the problem, they have yet to issue a recall to fix this issue!!! | Crash: No Fire: No | Unknown |
| Nov 2024 | POWER TRAIN,ENGINE | Engine developed a major oil leak at 70,000 miles, with multiple seals leaking. This appears to be a known defect with these vehicles and owners should not be bearing the cost for repairs. | Crash: No Fire: No | Unknown |
| Nov 2024 | ENGINE | The vehicle is low mileage (11,500 miles) and is burning an excessive amount of oil (up to a quart every 1,000 miles) The dealership is aware of this and just keeps saying to add oil. | Crash: No Fire: No | Unknown |
| Nov 2024 | UNKNOWN OR OTHER | I have a 2021 Mazda CX-5 touring with just a little under 26,000 miles. A couple of weeks ago, I started hearing an indescribable, quiet but noticeable sound on the passenger side of the vehicle that started at 15 mph. While attempting to get an appointment at two different booked up Mazda dealerships I noticed the sound getting worse and louder. I was able to get the vehicle into a local shop (not a dealership) close to my home. The technician there stated that my rear differential was leaking and needed to be replaced. He advised me not to drive the car because he said that I could lose total control of the vehicle. I was surprised to hear this as I was planning on picking up my son from school but also because my car has low miles on it. Luckily the repair was covered under my powertrain warranty but I felt the need to share with others. To me, this is a safety issue that Mazda owners should be aware of. | Crash: No Fire: No | Unknown |
| Oct 2024 | VISIBILITY | The outside mirrors failed to rotate open, and you could not see behind the vehicle. The mirrors rotate inward when the doors are locked and are supposed to open fully when the doors are unlocked. These outside mirrors can freeze when rotated in during freezing temperatures. When the vehicle is unlocked, the mirrors if frozen, can be kept from rotating out to the locked position. This condition causes the mirror motor assembly to fail and that prevents the mirrors from rotating to the outboard and locked position. Latter year models have an added option to turn the rotating feature off but no retrofit option was added to earlier model yesrs. | Crash: No Fire: No | Unknown |
| Oct 2024 | ELECTRICAL SYSTEM | Just got a oil change. Told my battery is almost dead. Upon looking up information I found a letter for recall for 2021 Mazda Cx5 for Dealer Rework 41 telematics communication unit concern. I called the Dealership and they are refusing to fix the problem. Looks like its just a software update is needed. My car only has 24,666 miles and according to the letter should be fixed. [XXX] I bought the car used in April and did a search for recalls prior to buying the car. There is non on Mazda website or vin search.

| Sep 2024 | UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE | 2021 Mazda CX-5. On 8/6/24, I turned right into a parking space between 2 parked vehicles at the DMV parking lot. I turned right and eased into the parking space facing a large Ford F 150 white pickup truck. I was approximately 1-1.5 feet from the front of the white truck. I had my foot on the brake, suddenly the vehicle accelerated by itself and I heard the car revving at a very high rpm and the car took off. My sister was a passenger and she heard it as well. None of the collision or brake notification avoidance features came on the screen or were implemented as a safety measure or accident prevention. I had my foot on the brake and I had no control over the vehicle. The car lurched forward hitting the right side near the headlight of the car on my left and the pickup that was in front of me. My car hit the white pickup so hard that it pushed it out of the parking space in front of me and perpendicular to the parked cars in the row. We both were injured, my sister in ICU and had to have emergency cervical surgery for fractures impinging her cervical spinal cord. The Mazda was totaled. It is impossible for a Mazda to push the Ford F 150 pickup truck, that was facing me , out of the parking space and perpendicular to the row of parked cars with just 12- 14 inches between the pickup truck and my vehicle unless it was revved up to a very high rpm. The police report has some inaccuracies, it states I was turning left into the space but was actually turning right and says I possibly passed out but that is not true. I was in shock when the police questioned me. I have also relived every second of this accident in slow motion many times since. I am a 5 foot women and would have had to floor the gas peddle and even then would not be able to push a large pickup truck out of the space in front of me, and continue out of the parking space landing sideways in a 12-14 inch space between the front of the 2 vehicles. | Crash: Yes Fire: No Injuries: 2 Towed Medical attention | Unknown |
| Aug 2024 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Will driving on the interstate, using the adaptive cruise control feature, vehicles were slowing down to a stop ahead and my car accelerated instead of slowing down. I then pressed the brake and simultaneously, the car breaks locked down (automatic braking). Unfortunately I wasn’t able to avoid an accident as I rear ended the vehicle in front of me. My vehicle has been turned over to the insurance company to assess damage. I’m sure it can be inspected by nhtsa. Mine and others safety were at risk due to the malfunction of the cruise control accelerating instead of stopping. It caused an accident. Luckily no one was extremely injured. I have neck and back pain from the collision that will hopefully heal in a few days. Time will tell. But this could have been much worse had I not reacted as quickly as I did. This could cause a fatal accident. The care isn’t drivable so it has not been reproduced by anyone. I have notified the insurance company about the issue and It is my hope that they will inspect this. There were no warning lights or messages displayed prior to the incident. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |
| Aug 2024 | POWER TRAIN,ENGINE | Oil has been leaking multiple times, with warranty repair for a faulty timing cover and gasket. This is now leaking again after being repaired twice already. This most recent time causing error messages regarding oil while driving. Significant burning smell coming from engine area. | Crash: No Fire: No | Unknown |
| Aug 2024 | ENGINE | For the third time in 3 years we have had to had the timing cover and gasket replaced due to major oil leakage. This appears to be a very common issue with this car, and even after getting it “fixed” the first time it is leaking again. | Crash: No Fire: No | Unknown |
| Jun 2024 | ENGINE | Low engine oil light 3600 miles before next oil change | Crash: No Fire: No | Unknown |

| May 2024 | POWER TRAIN,ENGINE | I got this suv in 2023 and I kept up with oil changes and I take it in for a oil change and not even 2 days later the oil light came on so I topped it off and I go in for another oil change not even 2 days later I'm running hot so I take it back to the dealer to find out I have either a cracked head or a blown gasket??!!! There is coolant visible and mazda told me they are aware of this problem but why aren't they doing something about it bc ppl are barely making ends meet and they continue to sell these cars with these engine problems without fixing the issue... | Crash: No Fire: No | Unknown |

| Apr 2024 | ENGINE | Oil light has come on indicating low oil. I have serviced this car through the dealership on schedule since I purchased it new. I don't believe modern cars should "lose oil" at less than 30,000 miles. | Crash: No Fire: No | Unknown |
| Apr 2024 | ENGINE | Cylinder head crack. Oil leak. | Crash: No Fire: No | Unknown |

| Feb 2024 | ENGINE | I thought this was for a mechanical issue (not a safety issue). Check engine light came on not blinking. Was code p0126 covered in bulletin 01-005/23 - Coolant Control Valve. I'm on the Facebook CX-5 page and I see that many people have had this issue. One person had the same problem twice on the same car. I would like very much to have the correct NHTSA link to report this problem so that others may report it as well. In my case check engine light came on far from home. A local dealer said it would be safe to drive home which I did (about 180 miles). But a problem that occurs many times on a given car model perhaps should be a recall. The only charge was about $75 from the garage who read the code and diagnosed the problem. It was covered under warranty so there was no further charge to me. | Crash: No Fire: No | Unknown |
| Feb 2024 | ENGINE | I had driven about 10 miles when the Check Engine light came on when I was far from home. Not blinking. It was not on when I first turned the car on. No symptoms other than check engine light. Got to a garage who got a code p0126 that is covered under TSB 01-005/23 coolant control valve. Called dealer who said it would be safe to drive home 180 miles. I did that. Awaiting appointment tomorrow to get it fixed. I belong to a Mazda Facebook group where lots of others are reporting this same problem - some for a second time! | Crash: No Fire: No | Unknown |
| Jan 2024 | SERVICE BRAKES | At 15k mi the rear left wheel started to squeal. Took car to dealer, they claimed all brake pads on the car worn out and replaced all of them (front+back), paperwork is available. That's an indication of a design defect impacting the brake system, this is not acceptable. Next week I was driving in winter storm and at one point the car started shifting to the left. I managed to regain control, dashcam video is available. I used to have a 2016 CX-5 and it experienced exactly the same issue. At one point dealer wanted to change brake pads after just 6k mi, I replaced them myself and noticed that the pads were worn unevenly, but it was easier to get rid of the car back then. The number of reports similar to mine is overwhelming, it is sad to see NHTSA not taking any action on this life threatening ticking time bomb. | Crash: No Fire: No | Unknown |
| Dec 2023 | ELECTRICAL SYSTEM | Screen blank when I am drving a while without any problem. I saw online and many owner have same problem. I followed company and online instruction. the problem could not be solved. | Crash: No Fire: No | Unknown |
