MAZDA Complaints

Issue Summary: Since December 27, 2024, my vehicle has experienced a hybrid malfunction and leakage issue three times. Each time this occurs, the vehicle becomes completely inoperable and cannot move, requiring a tow truck to take it to the dealership. Since December 27, 2024, my car has been in the shop four times, yet the issue persists. This raises serious reliability and safety concerns, as the vehicle can suddenly become unusa

Smelled smoke (burnt oil) for over a year. Dealer could not address. Finally found that the cylinder heads had cracked and required replacement at $7500. Car was only 51K miles.

The infotainment system within the Mazda has a variety of issues. 1. Its CarPlay system is extremely slow to connect to the mobile device via a USB. 2. 'Mobile Device Error' message pops-up frequently and disconnects the infotainment system from the mobile device. 3. 'Ghost Touch' occurs when driving under 20 mph. The screen fritz's out, will randomly press buttons, turn settings on and off, and there is no control over it. 4. Screen freezes. System and screen will either lag extremely slowly, or will freeze entirely. In sum, these issues are not only annoying but also a safety concern. It is extremely distracting for this to happen while you are operating the vehicle. Furthermore, it suddenly removes your mapping/navigation directions that you might be using.

There is a cracked cylinder head cover and the oil leaks from the crack onto the manifold causing smoke and burning smell. I have read several examples on Mazda forums [XXX] ; [XXX] ) of this happening with the Mazda CX-5. A former Mazda mechanic posted he would see a couple vehicles a week at his dealership that experienced this problem. The odor of the burning oil onto the manifold is overpowering when sitting in the car. Some people with the same problem have posted they actually had small fires / burning under the car. In May, 2021, Mazda issued a technical service bulletin TSB # SA-031-21 with a cylinder head redesign for 2018/2019 CX5 models. this is telling of their awareness of the problem. There were no dashboard warnings to indicate the problem - just the burning smell from oil and oil stains in the driveway which caused me to bring the car in. There is substantial evidence that this is a common problem with these model years and it is not related to the mileage of the vehicle - mine has only 37k miles on it. It should be noted that the cylinder head is aluminum and only 2mm thick vs 5-7mm on most vehicles. Mazda should be held accountable and issue a recall and/or extended warranty to address this problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2025 Mazda CX-90 PHEV. The contact stated that the hybrid battery failed to charge above 80 percent, and the "Engine Malfunction" warning light remained illuminated. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 25.

As reported by others, Engine Malfunction light came on. Car running rough. Mazda dealer says corroded wiring harness and $5k to replace. They bypass the conventional repair and splice it in. Within a hour of driving after pick up, same engine malfunction light and rough running returns. This time they said I need a new transmission. Electrical issues and faulty transmission are both dangerous. With as much posted online regarding the transmission, I would hope to find a recall. $10k in repairs for a barely 4 yr old car!

Vehicle had the dreaded 3 code battery malfunction. Charging system malfunction, critical vehicle malfunction (electrical leakage), & hybrid system malfunction. Making the car unable to drive and have to get towed. The car had me pull over at which point it could not be turned back on. It could not even be put into neutral and had to be pulled onto a flatbed truck. I bought the car on Dec 27th and Dec 28th it was broke down with 126 miles on it. It’s now Feb 22nd and they don’t know how to fix the car. This seems to be happening to many of these cars.

Received Hybrid Battery Malfunction and Electrical Leakage Detection alerts two weeks ago. Dealer has not been able to fix. First they said it was the water heater, then they said my radiator was leaking and I need a new one. Estimated 4 additional weeks for repair.

After backing out of my driveway, I put the vehicle in drive and the dash illuminated with malfunction errors. "Hybrid system malfunction", "Hybrid system electrical leakage detected stop the vehicle" and " I-activ sense partially disabled". I pulled back into my driveway, shut off the car for about 5 minutes and tried restarting. The car was disabled. Lights were still illuminated and then I couldn't get the car to move out of park. I called the dealership immediately and we arranged a tow for them to look at it. Day 2 at the shop and no answer as of yet. If my car went into limp mode and disabled my vehicle as I was driving, I could have caused an accident posing risk to myself as well as my children and other drivers. This malfunction has been happening to other CX90 and CX70 owners regardless of PHEV or MHEV vehicles. Please look into this. This is concerning with a brand new vehicle!

I purchased my CX-5 from Mazda dealership when new. The vehicle has been having coolant issues where the Electronically controlled thermostatic valve (ECTV) will open prematurely at 120°F instead of at higher temperatures. This all leads to higher fuel consumption, premature wear and tear on the engine, higher water condensation in the engine oil, poor engine and cabin air performance. I had it diagnosed at the Mazda dealership where I bought it from (Previously it was Sussman Mazda of Abington, now Fred Beans Mazda of Abington in PA) and they said the values are admissible by Mazda and not indicative of a problem. However, my vehicle cannot reach normal operating temperature of 198°F when driven for 50 miles at ambient 28°F for over an hour due to premature opening of the ECTV at lower temperatures. There are no codes showing up relating to the issue, therefore the dealership declined any repair works to be done.
