Misfire on other CX-5 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2016, 2017, 2020, 2021, 2026.
What this problem usually is
These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.
What got replaced
Few of these reports name the part that was replaced.
Recalls and investigations
2 recalls on the engine cover the 2019 model year. A recall on the same system isn't always the same failure, so read the defect text.
The impeller inside the low-pressure fuel pump may crack and deform, potentially causing the fuel pump to fail.
A software error in the powertrain control module (PCM) may cause the engine to stall.

Is this a known problem?
The manufacturer has sent NHTSA 41 service bulletins or notices for the 2019 Mazda CX-5 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

“Brought 2019 Cx-5 to local dealer with complaint of strong smell and smoke coming from hood. Cracked cylinder head at only 21k miles. Known flaw for this particular make and model. Only 6 months out of warranty. Mazda refuses to make it right and only extended warranty for turbo engines. Mazda needs to make this right for ALL engines with this issue.”

“I have 115k miles on my 2019 CX5. Never has any issues. Now all of a sudden I have a cracked cylinder head leaking oil. I was smelling smoke but mot seeing it. I took into dealership they noticed oil dripping thus why smell. Its a $4500-5000 job. I cannot afford this. This should not happen at this kind of mileage. My warranty just expired too. Mazda needs to cover these type of repairs”

Should you keep driving it?
This page can't tell you that. 0 of 103 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
