2019 MAZDA CX-5 Complaints

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 vehicle was out of the VIN# range. I firmly believe that the recall needs to be expanded to include a larger number of vehicles...you can google about this vehicle and see many others with similar issues. Usually, the cure is a PCM reflashing/software update that seems to take care of the issue. Please expand the recall before someone dies in an accident because of this problem.

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.

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.

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
