2019 Mazda CX-5

While driving, I received a warning that the engine in my car was overheating. Upon arriving home and parking, I noticed pooling under the car. My car was due for an oil change so the next day I dropped off the car for the oil change and mentioned the overheating message and leak to the technician thinking the fix would be routine. To my surprise, I was told my vehicle had a serious coolant leak related to a cracked cylinder. I was advised to take the vehicle to a Mazda dealer. Morrie's Mazda in Minnetonka, MN confirmed the cracked cylinder head which required a full engine replacement despite the car being only ~5 years old and having ~63,000 miles. Mazda had issued a technical service bulletin on this issue but had not issued a recall. As a result, I was left with a large repair bill to replace the engine in a relatively new car. This is a serious issue and I feel Mazda put my life and others in jeopardy by not recalling vehicles and letting customers drive with the risk of the engine overheating.

The infotainment system ghost touches on its own. It changes all car settings by itself. Active driving display, safety features like distance recognition, lane assist, blind spot monitoring, etc. Every setting available in the infotainment system gets changed or reset on it own. Even when you turn it off. It turns back on. GPS routes, dials people, hangs up, mutes on its own, etc. Mazda dealership says it’s out of warranty and I would have to pay out of pocket to fix it. However it is an ongoing issue where now there is a class action lawsuit.

Coolant leaks at cylinder head on 2019 Mazda CX-5 Grand Touring Reserve. Mazda North American Operations released a technical service bulletin (01-013/21) regarding 2016-2020 Mazda CX-5, CX-9, and Mazda6 with SKYACTIV-G 2.5T engines. This issue can cause the engine to leak coolant, overheat, and stall, potentially leaving the driver and passengers stranded in an unsafe location. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their manufacturers warranty period and placing costly repairs and potentially life-threatening situations as the responsibility to their customers. The diagnosis to repair this issue is a replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. This is a costly repair for diagnostics, labor hours, and parts and Mazda is refusing to be held responsible for these defects outside of the power train warranty period. Mazda customer support advised this will only be potentially covered if diagnostics are completed at a Mazda dealership and does not provide any assistance if the customer uses a non-Mazda affiliated repair shop. Messaging on the dash console advised excessive heat and thermostat was nearing 260°F

Started smelling smoke randomly and discovered an apparent oil leak in the engine. Mechanic inspected and noted that it appears to be an issue relating to the cylinder head/head gasket, which is in line with a technical services bulletin put out by Mazda several years ago for this make/model/year for a known design flaw that can result in catastrophic engine failure. I am just outside the five year warranty but well under the 60,000 miles, so expecting them to tell me they won't cover the repair even though this should have been a recall due to the potential outcome. I cannot drive the vehicle until this is repaired because it can cause engine fires (or worse).

There is a coolant leak at the cylinder head. We have been told that the cylinder is cracked at the back of the cylinder head where the exhaust ports meet. The dealer's technician said there is a "redesign" in the cylinder head. This is a known issue that is a defect apparently due to Mazda's design of securing the turbo on exhaust studs that are not designed to hold the weight. Why has there not been a recall? There is a Mazda TSB - 01-013/21, issued 10/15/2021 Verbal estimate from dealer for repair - over $7,000

My vehicle started smoking and I smelled a oil burning smell coming through the vents. I took it to the Mazda dealership and they diagnosed it with a cracked cylinder head. The repair estimate is $4,900. It is a 2019 with less than 60,000 miles, but it is a few months out of the powertrain warranty. However, this is a KNOWN issue to Mazda. As I have been researching online, many Mazda CX-5 owners have reported the same issue and I believe Mazda has traced it back to defective manufacturing in a batch of these parts. My local mechanic has also told us that he has seen this issue with 2019 Mazda CX-5s and recommended we report them. Mazda SHOULD issue a recall, but I understand that is expensive for them. At the very least, they should alerting drivers to this possibility and voluntarily repairing these cylinders without cost to unsuspecting drivers who could end up with an engine fire. I have submitted a complaint to Mazda customer service and I am awaiting a response.

The display screen appears to initiate "ghost actions". It will change songs, put phone calls on mute/hang up, change display settings etc. on its own. I looked this issue up online and it seems to be very common with 2017 and newer Mazdas. I took it to the Mazda dealership and they wanted to charge me $150 for a diagnosis and another $500 for a screen repair. I decided not to do it because all of the threads online stated that this didn't fix the issue so no diagnosis was made. It doesn't put me at extreme risk but it is very distracting when I am using maps or CarPlay.

I am writing to express serious concerns regarding the recent service that occurred on November 14th, 2023. Due to the service's failure and negligence, Luther Brookdale Mazda has jeopardized the safety and well-being of my family members. On [XXX], my 2019 CX-5 was towed from Monticello, Minnesota, to the dealership in Brooklyn Center around 9 pm. While returning from [XXX] dinner in St. Cloud on [XXX] , a sudden warning appeared on the dashboard: "Engine Coolant Temperature High. Stop the vehicle immediately in a safe place." Upon receiving this notification, we pulled over to the shoulder and observed smoke emanating from the engine bay. We promptly turned off the vehicle. Concerned for our safety, we contacted our family to pick us up and had the vehicle towed by AAA. As we awaited the tow truck's arrival, we noticed coolant had sprayed all over the engine under the hood, and the engine cover was missing. Furthermore, the coolant reservoir was below the minimum threshold. This particular issue is the reason I brought the vehicle in for service the week prior, regarding insufficient coolant temperature. It was evident from the state of the engine bay that the dealership failed to follow proper protocol. This lack of oversight likely resulted in damage to the engine and other essential vehicle components, leading to the total loss of the car. I am deeply disappointed by the lack of care and attention to detail in the service provided. This negligence also compromised my family's safety. Moreover, what was meant to be a festive holiday was marred due to the disregard for my property. I have been a loyal customer at Luther Mazda Brooklyn Park for several years, and I am shocked by the incident that has transpired. We have approached the dealer with the issue and they are continue to articulate that there is no engine damage, but with the ongoing class action lawsuit, I am extremely skeptical of their claims.

The INFO touchscreen randomly activates itself (the commonly reported "ghost screen" problem that occurs due to defective coating on touchscreen) which cause settings and selections to change uncontrollably, including placing phone calls, etc. This is very distracting and hazardous for this to randomly happen while operating the vehicle.
