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 “ghost touch” 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 you’re 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 touches that the drivers never initiated, therefore causing a distraction from watching what’s happening on the road ahead. Drivers have to take their eyes off the road ahead and shift over to the display to understand what’s going on if that is not also a safety issue I don’t know what is. Mazda has to be forced to issue a safety recall on the touchscreens for all affected vehicles.

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 to extend the warranty on this because it's not a turbo, this is a clever work around to avoid paying for something that should not be going out at this point. For this car being under 60,000 miles, been taking very good care of it, always had the oil changed, I feel that this is not fair for the customer to have to replace something on an engine that shouldn't be addressed for a very long time, if at all. I contacted Mazda corporate, they refused to do anything about it, I also contacted the Mazda dealership in my area, they contacted Mazda corporate and are not willing to cover this as well, my parents had a Mazda back in 2008 that had a similar problem. The only way this was resolved was going through Mazda corporate and writing a stern letter to their management team. At this point I've basically lost the trust of this manufacturer. I spent 25,000 dollars on this car, and now I'm going to have to spend 7 to 8 thousand dollars to get this part replaced, and that this point in the car’s life, that is outrageous. I will not be purchasing from Mazda ever again, there is plenty of documentation on the internet about this problem, and that Mazda refuses to do anything about it.

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. Mazda’s o􀆯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 (the federal safety agency ID MC-10246127-0001). Mazda’s documentation states the root cause of this chirp is excessive wear of the lock-up clutch inside the torque converter, which sheds iron powder directly into the automatic transmission fluid (ATF). The torque converter is a single, closed mechanical component. In January 2025, while the vehicle was fully covered under the 5-Year/60,000-Mile Powertrain Warranty, the torque converter's internal clutch was already undergoing accelerated physical degradation. Instead of proper mechanical diagnostics, the service department applied an electronic software patch. This patch merely altered the lock-up engagement timing to mask the torsional resonance rather than fixing the failing hardware. Applying a temporary software patch that delays a catastrophic component failure past a calendar date does not absolve Mazda dealership or Mazda Corporate of liability for a pre-existing, documented torque converter manufacturing defect which affect the entire power train of the vehicle. There are numerous complaints about this and subsequent failing transmission and expensive repairs reported so many online forums (reddit, facebook) again indicating this is a wide spread issue affecting consumer safety eventually leading to expensive out of pocket transmission repair. Mazda corporate need to be liable for this serious manufacturing defect on their transmission system.

Instead of physically inspecting the transmission fluid for iron contamination as dictated by sound mechanical diagnostics, your service department applied an electronic software patch. This patch merely altered the lock-up engagement timing to mask the torsional resonance rather than fixing the failing hardware.

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 2018–2019 CX-5 vehicles, but Mazda says my VIN is outside the recall population. I am concerned about a potential fuel-system safety defect.

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 mechanic. Maita Mazda ([XXX]) reprogrammed the TCM XXX, but now 16 months later, my car is exhibiting the exact same symptoms as before the TCM was reprogrammed.

This is a follow-up to my complaint 11754947, filed 8/5/2026 on the same vehicle. The defect has now been confirmed in writing by an authorized Mazda dealer. On 8/6/2026, San Francisco Mazda (repair order 1085786) diagnosed the cylinder head as the source of the engine oil leak on my 2019 CX-5 with the 2.5L naturally aspirated SkyActiv-G engine with cylinder deactivation, engine code PYUD. The dealer inspection report states: "CYLINDER HEAD LEAKING — FOUND THE CYLINDER TO BE THE SOURCE OF THE OIL LEAK." The repair estimate is $10,655.34, including a replacement cylinder head assembly, cylinder head bolts, and four gasket kits. Mileage at diagnosis was 51,483, approximately 7,000 miles per year, dealer-maintained since new. The technician inspection video shows engine oil actively dripping onto components below, and extensive burnt oil residue baked onto the metal surfaces above the engine. That residue is physical confirmation that leaking oil has been contacting hot surfaces repeatedly over an extended period. Still images from the dealer's own inspection video are attached. A burning oil odor is detectable both outside the vehicle and inside the cabin. Timeline. In April 2026 I found oil accumulating beneath the vehicle. On 5/18/2026 the same dealer (repair order 1079428) noted oil leaking from the cylinder head gasket area and from a plug near the firewall. The dealership replaced the valve cover, charged $1,218.26, and instructed me to drive 1,000 miles and return for reinspection. I drove 1,077 miles as instructed. During that period the leak persisted and progressed, developing the burning odor. On 8/6/2026 the same dealership confirmed the cylinder head as the source and confirmed the plug is not the source. I want to emphasize the safety implication of that sequence. An authorized Mazda dealer misidentified the source of an oil leak and instructed me to continue driving the vehicle for 1,000 miles. The oil was in fact reaching hot exhaust components duri
