2019 Mazda CX-5 complaints

The 2019 CX-5 AWD with the 2.5L NA engine (with Cylinder Deactivation) has an engine oil leak coming from the cylinder head area. The Mazda dealer confirmed the leak source and found burnt oil on the exhaust. The component is available for inspection. The leak location and symptoms are consistent with the known porous/cracked cylinder-head defect documented in this engine family. Full confirmation requires teardown. In early Dec 2025, a burning oil smell began, then thick white smoke came from under the hood while driving and after stopping. This created an immediate fire risk, and rapid oil loss could cause sudden engine failure or stall in traffic. The issue was inspected and confirmed by an independent mechanic, who noted the leak could only be traced after removing the exhaust manifold. The Mazda dealership then inspected it and confirmed the leak source at the cylinder-head area and the burnt oil residue. The problem has been reproduced and confirmed by both the independent mechanic and the Mazda dealer. No warning lights or messages appeared prior to the smoke. Mazda has an extended warranty program for the same cylinder-head defect on the Turbo engine, but no equivalent coverage exists for the NA engine, despite the identical safety risks.

While driving a short distance, my engine overheated and there was a strong burning smell. The cylinder head was cracked, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk and should not be driven. Mazda has issued prior Technical Service Bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2.5L turbo engine, but no program exists for the non-turbo engine, despite identical problems. Mazda should be held responsible for this safety issue. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their warranty period, placing costly repairs and potentially life-threatening situations on their customers. The repair is replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. Mazda’s refusal to extend reimbursement to non-turbo owners is unfair and leaves affected custom

Summary of Issue: The infotainment system in my 2019 Mazda CX-5 has been malfunctioning for a long period of time, and the issue has now escalated to the point where the system is unsafe and distracting while driving. Details: The infotainment screen intermittently “ghosts” and activates functions on its own—clicking through menus, changing settings, and moving erratically without any driver input. The system has also frozen and rebooted while the vehicle is in motion. This creates a serious distraction and safety concern. I previously reported this issue to the dealership, where they attempted a reset and told me to come back if the problem returned. The issue persisted and worsened. I recently returned, and the dealership diagnosed a communication failure between the CMU and the infotainment screen. However, they cannot identify any cause, and the screen itself has no physical damage and has never been struck. Mazda has declined to cover this under warranty, even though this appears to be an internal failure of components that should not fail at this mileage. Additionally, infotainment failures in Mazda vehicles have been the subject of prior complaints and service bulletins. Safety Concern: The malfunction causes the screen to operate unpredictably while driving, which distracts from the road and creates a risk of an accident. Because the system controls access to vehicle settings, Bluetooth, audio, navigation, and backup camera interfaces, the failure presents a potential

Question 1 - What component or system failed or malfunctioned, and is it available for inspection upon request? Answer 1 - The Engine Cylinder Head. The cylinder head developed a crack, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. Question 2 - How was your safety or the safety of others put at risk? Answer 2 - The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. Additionally, the loss of engine fluids creates a risk of sudden engine failure or stalling at highway speeds. Question 3 - Has the problem been reproduced or confirmed by a dealer or independent service center Answer 3 - Yes. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. The dealership acknowledged the failure and offered a partial repair discount, confirming their diagnosis of the defect. Question 4 - Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Answer 4 - Yes. The vehicle has been inspected by an authorized Mazda dealership technician acting as a representative for the manufacturer. I have also escalated the issue to Mazda Corporate (case number can be provided upon request), who reviewed the dealership's findings but refused to cover

What component or system failed: The cylinder head failed due to cracking around the exhaust manifold, resulting in exhaust and coolant leakage. My independent mechanic and the Mazda dealer both confirmed this was the source of the burning smell and engine risk. The failed parts are currently in the possession of the Mazda dealership and available for inspection upon request. Safety risk: The failure created a strong burning rubber smell inside and outside the vehicle while driving. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk if not caught early. I frequently transport children in the vehicle, and the unexpected engine damage posed a significant safety concern. Has the problem been reproduced or confirmed: Yes. The issue was first diagnosed by an independent, certified mechanic and then confirmed by the Mazda dealership, who determined the cylinder head had to be replaced due to premature cracking and leakage. Has the vehicle/component been inspected: Yes. The vehicle has been fully inspected by an independent mechanic and the Mazda dealership service department. The dealership stated the failed cylinder head will be sent to Mazda for engineering review. Were there any warning lamps or symptoms before failure: There were no warning lights or error messages prior to the failure - which is alarming. The only initial symptom was a strong burning rubber smell that began shortly before the diagnosis. No overheat

The Cyclinder Head cracked. This could cause the engine to fail, and leaving the driver on the highway or other unsafe locations of travel. The certified repair shop along with the insurance adjuster advised it was a manufacturing defect. The warning sign was an oil burning smell inside the vehicle while stationary and inside the garage.

Timing chain gasket leak, causing oil to go everywhere and smoking could cause a fire

Confirmed cracked cylinder by dealership, led to dumping of oil while vehicle was in motion on the highway. Vehicle/engine could have caught fire at any moment. There were no engine warnings that appeared on the dash. This is consistent with other CX-5 complaints on NHTSA. Vehicle had 55,000 miles on it at time of incident, and needed $8,000 worth of repair. Please recall!!

In August 2025, we brought our Mazda CX-5 (non-turbo engine) to a Mazda service center and paid nearly $3,000 for repairs, including replacement of belts and other related service. Despite this, we continued to experience a burning smell from the vehicle. Shortly thereafter, the problem escalated — the burning smell persisted and smoke began to appear. Mazda is now demanding an additional $4,500 to replace a cracked cylinder head. This defect must have been present when the car was serviced in August, and the initial repairs failed to identify or correct it. While there is an NHTSA Technical Service Bulletin for the turbo version of this engine, there are numerous complaints online about the same defect in the non-turbo model, which is what we own. This indicates that the problem is not isolated. Mazda should be held responsible for this safety issue. A cracked cylinder head that leads to burning smells and smoke is a serious hazard that could cause engine failure or even fire. Consumers should not be forced to spend thousands of dollars on repairs for what appears to be a widespread defect and when our vehicle has only $50k miles and it should last for the life of the vehicle.

Cracked/Leaking Cylinder Head on my 2019 Mazda CX5. It is understood that Mazda has extended warranty for the Turbo Model (CSP11) of this car, but not the standard engine, even though they both are displaying the same issue in many 2019 CX5s. Quoted at $6000 for a vehicle under 90K Miles. Issue needs to be escalated.

The contact owns a 2019 Mazda CX-5. The contact stated that while driving 30 MPH with a toddler occupying the rear seat, the contact noticed smoke and an abnormal burning rubber odor coming through the vents. The contact pulled into a gas station and then pulled into a nail salon parking lot. There was no warning light illuminated. The contact was able to drive to the residence, where an independent mechanic inspected the vehicle and found an oil leak, and the mechanic diagnosed that the cylinder head had cracked. The vehicle was taken to the dealer. The dealer informed the contact that the repair could not be covered under an unknown Extended Warranty because of the type of engine. The manufacturer was notified of the failure and informed the contact that the repair could not be covered under Goodwill assistance because the oil changes had not been mainly performed by the dealer. The vehicle was not repaired. The failure mileage was approximately 83,000.

Cracked Cylinder Head.

Dealership service department found a cracked cylinder head. This issue has been reported to NHTSA by Mazda. The car is being serviced and this issue was found. I’m attaching photos and also report from dealership l.

Timing cover oil leak. This is the same issue reported in technical bulletin #01-006/23 issued on 04/26/2023. There is oil leaking and the engine is smoking. No engine warning lights or other messages appeared. My car is a 2019 mazda CX-5 and has 31,954 miles. This problem has been confirmed by both an independent mechanic and the dealer service center. On 08/22/2025, I took my vehicle to dealer service for the repair. I also submitted a ticket to Mazda care for review of the case.

My vehicle was damaged by an as yet determined electrical fire seemingly having originated in the passenger door speaker components.

While operating the vehicle it will randomly start changing infotainment system settings. The radio station settings change, navigation maps will pop up and unprompted phone calls will be initiated. Each action is followed by a “beep.” Very distracting and requires actions that take focus away from operating the vehicle.

When accelerating, the transmission feels jerky/stutters. The check engine light and traction control light are illuminated and on the instrument cluster the messages: "Forward Smart City Brake Support Malfunction", "Smart Brake System Malfunction" and "Front Radar Sensor System Malfunction" appear. The vehicle acts like it doesn't know which gear it should be in, it'll buck pretty hard and then it refuses to accelerate...it feels like it's in a "limp mode". A previous driver of the vehicle complained and said that it actually stalled in traffic on the highway and was of course difficult to steer due to loss of power. I took it to a dealership and they came up with a laundry list of things to fix...most of which wouldn't have any bearing on this issue. I did have the serpentine belt replaced and the belt tensioner replaced due to wear on the belt and loose tension. On 7/16/25, I scanned the vehicle with a code reader, the codes P0301 and P0506 appeared. P0301 is a generic "Cylinder 1 Misfire Detected" message and P0506 is a generic "IAC system RPM Lower Than Expected. The vehicle was taken to a shop where the spark plugs and the cylinder 1 coil was replaces and the IAC cleaned. On 7/24/25 the same vehicle behaviors were observed and the same warning lights and messages were activated. I scanned the vehicle and got "p0300 Random/Multiple Cylinder Misfire Detected and P0304 Cylinder 4 Misfire detected. There was a recall on this particular vehicle make, model and year and my ve

For the 3rd or 4th time since I have own this car I experienced a loss of acceleration when attempting to make quick acceleration while attempting to merge with traffic. Acceleration is fine around town where quick acceleration is not appropriate. But the first attempt to merge with flowing traffic the car will slowly accelerates to about 30 mph and no more regardless as to position of accelerator pedal. On all occasion this bad behavior has this first drive of the day - going to work in the a.m. There is often a warning message indicating the safety radar is not working due to limited visibility which is a very common warning in the a.m.

There is a current lawsuit/settlement stating that there are known issues with the Mazda Connect Infotainment system having technical glitches. I own a 2019 Mazda CX5 and have been having issues with the Mazda Connect pressing random buttons, drastically increasing the volume, the carplay disconnecting while I'm following GPS directions, among other technical issues while I am driving. These are extremely dangerous issues while operating a vehicle and many Mazda owners are experiencing the same issues. With the limited extended warranty, I brought my vehicle into a Mazda service center to get the issue resolved. Although there are issues with the Mazda Connect Infotainment system, they claimed that the issue is not covered under the warranty and I need to purchase a new screen repair kit which would cost $608+tax. I believe they are trying to get out of repairing the issue and the repair kit they are recommending should be covered as well. A recall should be made to cover these issues.

I am the owner of a 2019 Mazda CX-5 (non-turbo) which experienced a cylinder head leak requiring full replacement. The repair was done by Riley Mazda of Stamford on July 28, 2023, at a personal cost of $4,074.34. Mazda has acknowledged this defect in turbocharged CX-5 models from the same year and issued a reimbursement program. However, Mazda has declined reimbursement for non-turbo models, even though the failure is the same, and the repair used identical part numbers and labor hours as listed in Mazda’s own TSB for the turbo reimbursement. This indicates a broader issue affecting both engine variants. Mazda’s refusal to extend reimbursement to non-turbo owners is unfair and leaves affected customers with no support for a known manufacturing flaw. I urge NHTSA to investigate this recurring engine defect in non-turbo 2019–2020 Mazda CX-5 models and encourage Mazda to offer equal reimbursement.

My infotainment system regularly ghost jumps between screens and adjusts the volume of music (both on CarPlay and regular radio) by itself. The car turns off CarPlay regularly, including the navigation, which is dangerous when you are not sure where you are going. The sound is the worst part of it, as it will change the volume to unhealthy levels without warning. Even turning it off does not stop the jumping, as it turns itself back on. While Mazada did provide an extended warranty for this exact problem, they will not cover the display which they allege is the problem in my car and told me it is a $600 replacement fee that I am fully responsible for, even though their screen does not work. This issue is all over the internet with Mazda refusing to fix it but it's an issue that can cause serious safety issues (with navigation failing and especially with unexpected volume changes). There is no rhyme or reason to when it happens and when it doesn't. It will be fine for a few days and then not work at all for a day. This has been ongoing for about a year. My car has about 55,000 miles on it.

While driving on a 75 degree and sunny day my Sunroof exploded. There were no cars around that could have thrown debris up. Luckily I had the shade cover closed or I would have been showered with broken glass.

My vehicle has 64k miles and has had regular maintenance - oil changes, etc. it has recently developed an oil leak. I took it to the dealer today & they said the cylinder head and gasket needs to be replaced. My car has not overheating or even run warm. I understand there are 2019 CX-5S that have had a casting issue with cylinder heads. I feel sure that’s what the issue is here yet they want almost $6k to repair my vehicle!

I’m reaching out regarding a persistent issue with my Mazda 2019 cx5 infotainment system. The screen is experiencing frequent “ghost touch” or phantom button presses, where functions are activated without any input. This makes the screen erratic and often unusable, creating a distraction and raising safety concerns while driving. I’ve already restarted the system and attempted basic troubleshooting, but the issue continues. I’ve learned that this is a known issue in various Mazda models, and I believe this should be covered for repair, especially since it impacts both functionality and driver focus. I’ve already contacted Mazda customer service and my local dealership; however, they advised that the repair would need to be paid out of pocket. Given the nature of the issue and the potential safety concerns it presents, I strongly believe this is something that should be covered by Mazda. Please let me know how I can escalate this issue for formal documentation and create a new recall. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2019 Mazda CX-5. The contact stated that while operating the vehicle, the message that the engine oil level was low was displayed. The contact stated that oil was added to the engine; however, the next day the message reoccurred. The contact stated that later while the vehicle was parked, the contact discovered an oil leak underneath the vehicle. The vehicle was driven to the local mechanic who confirmed oil leaking from the engine, but the cause of the oil leak was not yet determined. The local dealer was contacted, and a service appointment was scheduled. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer was not contacted about the failure. The failure mileage was 96,600.

One of the cylinder heads on the back portion of the motor cracked, leaking oil down into the engine compartment. I didn't realize this was an issue until I got a warning about low oil. I went and got an oil change and within 2 days I had the low oil warning again. I had no other warnings that this was going on. This creates a potentially dangerous situation with people leaking oil onto roads and highways unknowingly. It was inspected by Mazda and confirmed to be the issue. There is currently a TSB from Mazda about it. But my car wasn't included in it. TSB 01-002/23

Just got diagnosed with cracked cylinder head. After looking on social media, it appears this is a thing for the model years 2018 and 2019. Bad casting? Anyway I believe this should be a voluntary recall to correct such a flawed engine. I bought this new from a Mazda dealership and kept it up to date with service only through the dealer. The 60 month/60,000 mile drive train warranty ran out last July. However I only have 50,000 miles on the car...babied.

At 30,000 miles car began leaking oil severely and was told that the engine block was cracked and needed to be replaced. There are numerous complaints of this same issue online happening just after the warranty has expired. The cost of repair is $6000.

Unknown. Ticking noise on engine.

The engine cylinder head cracked before the vehicle hit 50,000 miles. This caused oil to leak and burn in the engine compartment, leading to a burning smell coming into the cabin. Once enough oil had been lost, I got a low oil pressure light. I immediately pulled over and noticed white smoke was coming out from under my hood, and the smell of burning oil was quite strong. The problem has been confirmed by my mazda dealer. The vehicle has not been inspected by manufacturer, police, insurance. Just the dealer. The vehicle is currently at the dealer, and the cylinder head would need to be removed for inspection if requested. The smell of burning oil was the only early symptom, though I did not recognize it at the time.

The contact owns a 2019 Mazda CX-5. The contact stated that while driving up on incline at 45 MPH, the engine shut off with the check engine warning light flashing on the instrument panel. Despite the failure, the contact was able to pull the vehicle off to the shoulder of the road. Due to the failure, the vehicle was towed to the residence. The following day the vehicle was towed to an independent mechanic; however, the mechanic was unable to duplicate the failure. The mechanic replaced the spark plugs and the ignition coil. The mechanic referred the contact to the dealer for additional assistance. The contact drove the vehicle to the dealer with an abnormal rumbling sound coming from the vehicle. While at the dealer, the dealer was unable to determine the cause of the failure. The contact was provided an estimate for repairs unrelated to the failure. The manufacturer was notified of the failure and provided a case number. The vehicle was not repaired. The failure mileage was a 129,000.

The Mazda Connect screen has ghost touch issues. The screen randomly presses buttons while the vehicle is in motion. The most dangerous component is when it changes the lighting to nighttime during the day causing me to be unable to see my screen during the daytime. It also repeatedly skips music, changes the screen while the gps is on, and constantly presses random buttons and disturbs me while I'm driving the vehicle. This is a known issue amongst many Mazda models that they have yet to fix and it is highly distracting.

Valve cover develops crack causing significant loss of oil resulting in seizing of engine with the potential of serious accident and potential loss of life.

I had my vehicle looked at and found a cracked cylinder head on #3 and did some research of people having the same issues. I was driving when the vehicle started smoking it turns out the oil coming out of cylinder #3 flows down the driver and passenger side behind the exhaust manifold which can lead to a fire. My car only has a little over 80,000 miles and this should not happen around that low of a mile vehicle. I believe this is an issue that needs attention.

While driving, the infotainment screen went crazy! It randomly changed screens rapidly, and the navigation voice started talking loudly about changing volume level, and repeatedly. Very distracting and dangerous.

This is a complete electrical system failure. My screen continues scroll All Systems fails. At least it is not draining the battery again. I have had to replace the battery 2 times in the last 6 months. Maybe CarMax sold me a "lemon". . I received a recall notice, however when I spoke with the service department at the Bob Mazda dealership in Carlsbad and they told me that the recall on my vehicle is closed. I can come in for repairs, but at my own expense. I have only owned this vehicle for 6 months in which 2 months I was in the hospital recovering from a major surgery. When I get in my car and start it, if it starts the "blue" light is on every time, which is apparently Thermostat. After about 20 minutes or so the light turns off, sometimes 30 minutes. The next part is the scrolling malfunctions. It lists about everything on the car. I am [XXX] and live in Baja. I live in a very safe, gated with a security guard neighborhood, however I am scared of going any due to my car issues and being stranded. I also really need to cross the border to see my doctor but I am afraid. When you have to replace 2 batteries in 6 months and I have only driven under 5,000 since I purchased the car. Mazda needs to make me whole. My car also only has 24,000 and when I bought it had20,000 miles. There is something seriously wrong, actually multiple things are wrong with my 2019 Mazda. A person should never be afraid to get in the vehicle due to safety issues. INFORMATION REDACTED PURSUANT TO THE

The contact owns a 2019 Mazda CX-5. The contact stated that while the vehicle was parked, the contact discovered an abnormal odor coming from the engine compartment. No warning light was illuminated. The vehicle was taken to a dealer, where it was diagnosed that there was a cracked cylinder head and that the cylinder head needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 26,000.

Cracked cylinder head. Major oil leak. Oil light came on but then turned off. No other warning light. No engine light came on. The vehicle was taken to the dealer for diagnosis.

The cylinder head in the engine cracked while I was driving. The vehicle was leaking oil profusely and was down a quart after the oil had been changed the week prior. There were no warning lights or indication and I had just had the vehicle in the dealership the week before. I'm a disabled driver that requires hand controls so if I needed to exit the vehicle and move away from it it would not be possible. It's been at the dealership since 2/24/25. I have found numerous other people that have experienced the same issue online.

With only 60k miles on my car which I regularly take in for maintenance, my car started to leak a ton of oil. It was determined that the cylinder head is cracked. This should not happen on a car this new and maintained. In doing research, this seems to be a common occurrence with this year.

On [XXX], I was the operator of a 2019 Mazda CX-5 in Los Angeles, California. I parked the vehicle on an incline on or around [XXX] in Los Angeles, California, and then exited the vehicle. The vehicle remained stationary for some time, until it suddenly began rolling backwards at a speed that pushed me to the ground while I was getting my things from the passenger side door, causing me serious injuries.

The cylinder head on my 2019 Mazda CX-5 failed prematurely due to a known defect. The vehicle is currently at Fred Beans Mazda in Mechanicsburg, PA, where the issue has been diagnosed and confirmed. The defective component is available for inspection upon request. This failure created a serious safety risk due to an oil leak, which led to smoking from the engine bay and a potential fire hazard. If the oil had ignited, this could have caused severe vehicle damage or injury. Additionally, the failure could lead to a sudden loss of power while driving, increasing the risk of an accident. The problem has been reproduced and confirmed by the dealership, and Mazda has been contacted regarding assistance. They have acknowledged the issue but have not provided full coverage for the repair. Prior to the failure, there were no warning lights or messages. The only symptom was an oil leak, which led to smoke coming from the engine. This issue appears to be a common problem with this model, and Mazda should take responsibility for addressing it properly before it causes serious harm.

While driving the vehicle, I started smelling a burning smell about 10 days ago (2/17). I also felt a slightly reduced engine performance and could see the car emitting smoke from the engine bay. I had no warning lights on my dash. For all I know, the engine could've blown while I was driving on the road. Upon taking the vehicle to the dealership 2 days ago (2/25), they informed that my car has a cracked cylinder head, and there was no apparent reason why this would happen. The vehicle has only been inspected by the dealership thus far and I was quoted $5,700 to fix the issue. Upon looking up the problem, I see this is a common issue, with many having experienced it before, but no TSBs issued for this. There is a CSP issued for vehicles of the same year, but limited to the Turbo version on the engine. Unfortunately, I do not have any warranty on the car currently.

This concerns a 2019 Mazda CX5 with approximately 52,000 miles - the engine of this vehicle is the 2.5L naturally aspirated version. Driving the vehicle with the HVAC system on resulted in a burning oil smell coming through to the cabin. Upon owner inspection, engine oil was seen as coating the underside of the vehicle in various areas. The oil pan drain plug and oil filter were both found to be tight and not leaking oil. The vehicle was taken to a nearby Mazda dealership for inspection on 2/26/2025. On 2/27/2025, Mazda technicians state that the cylinder head on the vehicle engine requires replacement. Replacement is quoted to be in excess of $5000. Reviewing the issue online shows numerous similar cases of engine cylinder head failure. This vehicle comes equipped with cylinder deactivation which seems to have a higher rate of failure regarding cylinder heads and a potential design flaw with cylinder heads manufactured in a time frame of 2018-2020. Leaking oil could potentially start a fire as the oil drips onto the exhaust manifold when the car is at operating temperature.

The infotainment system within the Mazda has a variety of issues. 1. Its CarPlay system is extremely slow to connect to the mobile device via a USB. 2. 'Mobile Device Error' message pops-up frequently and disconnects the infotainment system from the mobile device. 3. 'Ghost Touch' occurs when driving under 20 mph. The screen fritz's out, will randomly press buttons, turn settings on and off, and there is no control over it. 4. Screen freezes. System and screen will either lag extremely slowly, or will freeze entirely. In sum, these issues are not only annoying but also a safety concern. It is extremely distracting for this to happen while you are operating the vehicle. Furthermore, it suddenly removes your mapping/navigation directions that you might be using.

The contact's daughter owns a 2019 Mazda CX-5. The contact stated that while her daughter was driving at undisclosed speeds, the Mazda Connect Center Display touch screen was operating independently, causing vehicle functions to be engaged unintendedly. The contact was concerned for her daughter's safety because the center display functions included safety lane departure warning, blind spot monitoring, and traffic sign recognition safety functions. The contact related the failure to Mazda Special Service Program (SSP) Number: B6. The dealer and the manufacturer were notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 30,000.

I hope this message finds you well. My name is [XXX] , and I am the owner of a 2019 Mazda CX-5 purchased as part of the Certified Pre-Owned (CPO) program. I am writing to formally address two concerning issues related to my vehicle’s warranty coverage and its safety. 1. Warranty Coverage for Drive Belt Tensioner: During a recent visit to your dealership, I was informed that the drive belt tensioner on my vehicle is not covered under the warranty. This contradicts the coverage listed on your official Mazda CPO Warranty, which specifies that the Limited Powertrain Warranty includes the engine, timing chain, tensioner, and associated components. The drive belt tensioner is clearly referenced in this section, yet I was told it falls under wear and tear and is not covered. I kindly request a detailed explanation regarding this discrepancy. I believe the information I was given does not align with the warranty’s stated coverage, and I am concerned that the dealership is not honoring the terms of the warranty as outlined on your website. 2. Ongoing Noise Issue: Additionally, my vehicle has been making an unusual noise, which I reported during my visits to two separate Mazda dealerships. Unfortunately, despite multiple attempts to diagnose the issue, neither dealership has been able to identify the source of the noise. This situation has left me feeling unsafe while operating the vehicle, as I am unsure of its origin or potential impact on my vehicle’s performance or safety. I would

Center multimedia display malfunctioning by ghost touching. Without using the commander switch, touch panel, or voice recognition, the screen will scroll through settings, apps, change radio stations, etc. Additionally, it will turn off maps in Apple Play when the program is in use. There are several complaints and examples of this issue online: [XXX] This concern needs to be addressed because it is safety issue as it is a major distraction for the driver. Service appointment with Westcott Mazda on 2/10. Originally brought in 1/28 for appointment, but was advised by Mazda service representative to contact Mazda as car is out of warranty.

Car will slam on brakes even if car is in opposite lane farther away. We have received sooo many chips amd cracks on windshield with 2 weeks. We purchased used and was informed windshield was replaced once already.

Oil started leaking while car was idling causing smoke to enter the cabin as well as all under the hood. Car was undriveable at this point. She was lucky there was no traffic. Car had to be towed and cylinder head was cracked. Mazda has a known faulty cylinder head problem they have refused to fix and this caused a safety issue. Vehicle will not be able to be inspected as we had it towed to get fixed immediately. The service center did confirm this is the issue and there were no prior issues before this.
