7 year old vehicle purchased new 2/23/2019 with 80,000 miles driven. Rear of cylinder head has cracked causing an oil leak. Leaking engine oil dripping directly on the exhaust components creates an immediate, severe under hood fire risk and visibility hazard while driving.

The âghost touchâ issue with the touchscreen on the display on my Mazda is added to all the 1000s of others reported on multiple sites by consumers on the internet. It is a very serious destruction from driving and that is a safety issue. Mazda has issued a technical bulletin but that is forcing consumers into buying another display board for something consumers did not cause and cannot afford. Why is this a safety issue? Because when youâre driving or stopped at a traffic light, the screen will randomly float from one input to another, sometimes even dialing people from the contacts list that is synchronized from your smart phone or inexplicably, changing stations and responses to…

I purchased a used 2019 Mazda CX-5 in 2024, with 25,000 miles on it. In June of 2026 I started to have an oil leak. Took it to a mechanic's shop who diagnosed it as a valve cover gasket, ran the car for another 2 months, oil leak did not stop, got worse, to the point where my oil light came on where the oil was low enough, then I took it to another mechanic, they diagnosed it as some sort of pressure sensor that has to do with the oil, they replaced that, then that still wasn't the case, it was leaking, and they diagnosed it as a cracked cylinder head. This has been an issue with Mazdas in the 2018 to 2022 range for the CX-5s, and Mazda knowingly has put in faulty parts and is not willing…

1. January 2025 Diagnosis (Inside Powertrain Warranty): I presented the vehicle (2019 Mazda CX5, 36K miles) with severe transmission jerking and shift lurching at a local Mazda dealership. Technicians diagnosed teh issue as described in TSB 05-004/23 and applied a software flash to the PCM/TCM stated in TSB 05-004/23. Mazdaâs oô¯icial text states the root cause of this symptom is torque fluctuation and torsional resonance within the torque converter. 2. Current Symptom (Defect Manifestation): The vehicle now exhibits the distinct upshift chirp detailed in TSB 05-005/23 (NHTSA ID MC-10246127-0001).

2019 Mazda CX-5 developed P0192-00 fuel-pressure-related fault and significant loss of acceleration/limp mode. Mazda dealership diagnosed fuel rail/injector-seal issue and performed approximately $2,836 in repairs. The condition was not corrected. Dealer now diagnoses a high-pressure fuel-pump failure and is requesting an additional $1,459. Vehicle has experienced loss of power while driving. There is an existing Mazda fuel-pump recall affecting some 2018â2019 CX-5 vehicles, but Mazda says my VIN is outside the recall population. I am concerned about a potential fuel-system safety defect.

The contact owns a 2019 Mazda CX-5. The contact stated that while driving at 55 MPH and turning into a driveway, smoke emerged from the engine compartment. The vehicle was turned off and inspected. Upon opening the hood, smoke was observed near the rear firewall of the engine compartment, and oil was leaking under the engine compartment. The source of the leak could not be identified initially, and the vehicle was towed to an independent mechanic, where a leaking cylinder head was diagnosed. The vehicle was not repaired. The vehicle was then taken to a dealer, where it was confirmed that the cylinder head was leaking oil and needed replacement. The vehicle was not repaired. The manufacturer…

In early 2025, my 2019 Mazda CX5 automatic would not shift always shift when it should - - it would take several seconds. This was especially concerning when I merged onto freeways and when I drove up hills or steep roads, and needed to pass a slower vehicle. The problem was especially noticeable & lasted longer when the engine was cold. I took the car to my mechanic who said it was the TCM, there was a recall notice, & that I needed to take my car to a dealer. (I never received a recall notice.) I took my car to Mazda in Sacramento because my local dealer (Salinas, CA) would not address the issue without me paying a $395 "diagnostic fee" - - even though I had the recall info from my…
