Mazda CX-80 KH
Weaknesses, engine ratings and buying advice
Engine Overview
The Mazda CX-80 KH is available with 2 engine variants — from 191 to 254 hp.
3.3-litre inline-six diesel with 48V mild hybrid. Mazda's first inline-six in decades, on the new longitudinal platform.
- !! AdBlue Dosing Pump Failure from 60,000 km
The AdBlue dosing pump can crystallise and block during short-trip use. SCR catalytic converter efficiency drops, engine power is reduced. The first Mazda with an SCR system.
Symptoms: AdBlue warning light, power reduction after 1,000 km, engine will not restart after countdown, elevated NOx emissions. - !! Injector Failure with Engine Damage from 50,000 km
Isolated cases of injectors leaking fuel into the combustion chamber. Hydrostatic lock possible. Mazda recommended preventive injector checks on early CX-60 diesel engines.
Symptoms: Knocking noises, rough running, strong diesel smell, white smoke cloud, sudden engine failure in extreme cases. - !! Recall: Transmission Software 8-Speed Automatic
The new 8-speed automatic (Aisin) had software problems with the shift logic during manoeuvring and at low speeds. Multiple recalls in 2022–2023.
Symptoms: Juddering during manoeuvring, delayed gear engagement, unintended downshifts, transmission warning light.
+ 3 more engine weaknesses + vehicle weaknesses
2.5-litre naturally aspirated engine combined with a 100 kW electric motor as a plug-in hybrid. Pure electric range around 60 km, system output 241 kW.
- !! Recall: unexpected engine shutdown
A software fault in the hybrid control unit can cause the combustion engine to shut down unexpectedly during certain acceleration scenarios. Recall in 2022 for CX-60 PHEV vehicles from the first production months.
Symptoms: Engine shuts off during driving, abrupt switch to EV mode, fault message in the instrument cluster, power loss. - !! Recall: Transmission Software Shift Logic
Faulty transmission software can cause unintended gear disengagement. Recall affects CX-60 PHEV and diesel variants from the first production years.
Symptoms: Gearbox shifts unintentionally to neutral, loss of drive, transmission warning light, jerky gear changes. - !! Jerk during electric-to-combustion engine transition
The transition from pure electric drive to combustion engine engagement produces a noticeable jerk. Occurs at low speeds and under light acceleration. Software updates improve but do not fully eliminate the problem.
Symptoms: Distinct jolt when the combustion engine cuts in, especially at 30–50 km/h; gearbox shudder at low speed.

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Rear Air Conditioning Not Working Several CX-80 owners report the rear air conditioning not working from the moment of handover. Mazda replaced the AC compressor in some cases without permanently resolving the issue. The cause is likely a faulty connector in the gearbox area. Symptoms: Rear vents not blowing cooled air, air conditioning switching itself off or not responding to settings from 5,000 km | Medium |
