2018 MAZDA CX-5 Complaints

2018 Mazda CX5 2.5 ltr engine. Major oil leak that has been diagnosed as cracked or porous aluminum casting on the cylinder block. Oil is dripping consistently out of the problem area onto the manifold, causing smoke to flow into the cabin of the car and out of the hood as well. Car is currently at a Mazda dealership for a second diagnosis that confirmed the leak. Car is 3,000 miles out of warranty. Waiting to hear what the dealership is going to do. I also have contacted Mazda corp. and have a case# to take further action if needed. As you can see by the list of "engine" complaints for this problem, it is well documented that this is not an isolated issue.

The contact owns a 2018 MAZDA CX-5. The contact stated that while driving at 45 MPH, the infotainment system displayed a blank screen, then one minute later, the infotainment screen displayed as intended. The contact pulled over to the right side of the road and turned on and off the vehicle and the infotainment system displays as intended. The contact mentioned that this failure has occurred on several different occasions. The contact stated that the infotainment system independently displays calls, and the radio comes on independently. A dealer was contacted. The vehicle was not taken to a dealer or independent mechanic for diagnosis or repairs. The manufacturer was not notified of the failure. The approximate failure mileage was 70,000.

Started 2018 Mazda CX-5 and the engine was extremely loud and a ticking noise was heard. Brought it to my local garage (Charlies Garage) and it was determined that the lifters needed replacement. Garage told me that Mazda issued a Service Alert on November 22, 2019 (Alert # SA-012/19) and did not notify customers of the Valve Tapping or knocking noise from cylinder head. The Garage then told me that Mazda issued a Technical Service Bulletin on April 23, 2020 (Bulletin No. 01-006/20). Again, customers were not notified of the Tapping Noise from Engine Bulletin that was issued. There were no alerts on the dashboard of the car, no warning lights, or other indicators. If Mazda had notified customers, the car would have been fixed UNDER WARRANTY. I do have a video of the noise and if you let me know how to send that, I will.

Car started leaking and burning oil. Blue smoke coming out of engine. Low oil pressure light went on. I had it looked at by an auto mechanic. This is a major safety issue as the engine will fail because of the low pressure. The car is not drivable. Turns out it's a known issue with the cylinder head that Mazda knows about because they issued a redesign and issued recalls for the 2019 and the turbo engine. They also issued a TSB for this problem. Car is out of warranty, but not old enough to have major engine issues.

My vehicle is affected by a well known "ghost touch" infotainment touch screen issue. Due to safety hazard nature of this issue, Mazda had a recall program but it only covered Mazda3 models (Special Service Program SSPB6 - see attached file). My issue was diagnosed and confirmed by an authorized Mazda dealer (see attached file). I contacted Mazda customer center about this issue and they declined any help "due to the mileage and service history" (case number: 00284155). Mazda acknowledged that "ghost touch" issue is caused by manufacturing error but apparently they are not willing to fix it unless forced to, even though the issue poses a safety hazard.

I noticed a burning smell coming from engine. I took it to a Mazda dealership where they found a cracked cylinder head that needed complete replacing. There was no warning light or other symptoms before I noticed the smell. Vehicle has only been inspected by the dealership. Vehicle is out of warranty but only has 37000 miles on it.

Defective Engine. Cracked Cylinder Head. Engine oil leaked overnight because of known Mazda 2.5 liter Skyactive engine defect.

The issue began when I started to smell burning oil. As time went on smoke began to slowly come from the hood. I took my car to the mazda dealership and said that there was a cracked cylinder head in the engine. After doing research online this has been a major issue with the 2018-2020 model.

I am writing to formally report an issue with the infotainment screen of my Mazda CX-5, which has been experiencing a malfunction known as “ghost touch.” The details of the complaint are outlined below: Component/System Failure: The component that has failed is the infotainment screen of my Mazda CX-5. The issue involves persistent and random “ghost touch” inputs, where the screen registers touches and activates functions without any physical interaction. This component is still available for inspection upon request. Safety Risk: The malfunctioning infotainment screen poses a safety risk as it results in unintended activation of various functions, including navigation, audio, and phone settings. This distraction while driving can cause the driver to lose focus and potentially lead to accidents. Reproduction of the Problem and Inspection: The problem has been reproduced and confirmed by Browning Mazda dealer and was told that the manufacturer does not believe this poses a safety risk but I strongly disagree Prior Warning Signs: No warning lamps or messages appeared before the issue began. The problem first appeared in 2021 but was reported in 2022

My 2018 Mazda CX-5 with just over 45,000 miles is showing the dreaded cracked cylinder head symptoms. Coolant is leaking causing a very noticeable burning smell in the cabin and faint smoke emanating from under the hood. My CX-5 has followed the maintenance schedule at the dealership that the vehicle was purchased. At this point the dealership has not been helpful at all. Mazda MUST start including 2018 CX-5s to CSP11 (covers 2019 CX-5s).
