2018 Mazda CX-5

Infotainment screen experiencing “ghost touches”, meaning that safety features can randomly be selected, activated and de-activated, and distracting actions happen in the infotainment system while vehicles is in motion. This is a known issue in Mazdas, and a recall has been issued for 2014-2016 Mazdas to replace the infotainment system. However, this issue is also happening in later models, including the 2017 to 2020 Mazda CX-5. This issue has been diagnosed by the dealership (Roger Beasley Mazda in Georgetown) and the system throws an error, CMU DTC 1 - B108E04 (Display-System Internal Failure).

We were driving and noticed some white smoke when we parked, so we took it to a mechanic and he diagnosed: “Found that only when engine gets up to operating temp that it begins to leak through hairline cracks in cylinder head. Oil leak is severe and recommend not driving and bringing to dealer for possible warranty verification.” He told us the issue is specifically on the driver side where there are hairline cracks on the backside, left quarter of the cylinder head.

There is a known issue with 2018 Mazda CX 5 related to a cracked cylinder head. I have just under 60,000 miles and I noticed smoke coming from under the hood near the exhaust manifold and a strong odor of burning oil. Dolan Mazda in Reno, NV has confirmed I have a cracked cylinder head and it is the cause of the burning oil. I am concerned that oil leaking from the cracked cylinder head onto the exhaust is a fire hazard. I feel a recall should be issued.

We purchased our vehicle from Riley Mazda in September 2018. Shortly after reaching approximately 50,000 miles, we began to notice that the gauges would fluctuate, and there was a slight burning odor in the car cabin. We replaced the air filters for both the engine and cabin, as well as performed an engine oil change. In October, we had a brake flush done when we inquired about the burning smell coming from under the hood. Despite our concerns, the dealership was unable to identify any problems at that time. On a subsequent visit, we paid a diagnostic fee of $220.00. It was during this visit that the dealership discovered an issue with the engine. The newly identified problems will significantly impair the vehicle's performance and decrease its value. Additionally, we anticipate needing future repairs, which could pose serious safety hazards.

After online research, other people with Mazda vehicles have had the same problem and it’s called ghost touch. My screen controls go automatically without me touching any dials while I’m driving, which is extremely distracting and unsafe. I have tried to get it fixed by a few dealerships and they either put it off or say it’s not under warranty/recall.
