2018 Mazda CX-5

The contact owned a 2018 Mazda CX-5. The contact stated that while her daughter was driving at 35-45 MPH, the vehicle was shaking and rattling. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that the wheel bearings were faulty. The vehicle was repaired but the failure recurred. The vehicle was taken to the local dealer again where it was diagnosed that there were loose parts in the engine. The vehicle was repaired but the failure recurred. Additionally, the brake light was illuminated. The vehicle was taken to the dealer where it was diagnosed that the switch and mat were causing the failure. The vehicle was repaired and returned to the dealer. The manufacturer was contacted. The failure mileage was approximately 31,673.

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.
