Mazda CX-70 TY
Weaknesses, engine ratings and buying advice
Engine Overview
The Mazda CX-70 TY is available with 2 engine variants — from 328 to 345 hp.
Plug-in hybrid based on the 2.5L SkyActiv-G with two electric motors and 241 kW system output. Acceleration is impressive, but early software struggled: drive power loss in EV mode, defective 48V batteries, and multiple recalls defined the first model years. 2025 units are substantially more stable after the recall software updates.
- !! Recall: Drive Power Loss in EV Mode (7024J / 6323J)
Multiple NHTSA recalls affect the CX-90 PHEV: faulty PCM/ECM software can cause sudden loss of drive power in EV mode. Campaigns 6323J, 7024J, and 7124J collectively affect over 150,000 MY2024–2025 vehicles. Mazda performs free software updates at dealers.
Symptoms: Multiple warning lights at startup, vehicle enters limp mode, drive power drops out in EV mode, vehicle fails to restart after i-Stop - !! 48V Hybrid Battery Early Failure from 30,000 km
Several CX-90 owners report 48V lithium battery failures between 20,000–40,000 km. Replacement parts ship from Japan and lead to wait times of several months. Affected vehicles often sit at the dealership for weeks.
Symptoms: Hybrid System Malfunction warning, vehicle stalls or suddenly loses drive power, multiple simultaneous warning lights
New inline-six turbo producing 280 or 340 hp, debuting in the 2023 CX-90. Smooth power delivery and strong torque. The 48V mild-hybrid integration and the new 8-speed automatic showed software maturity issues on early production units — shudder on launch is the most common complaint, usually addressable via software update.
- !! Transmission Shudder at Low Speed and Launch
The 8-speed automatic in the CX-90 and CX-70 shudders, especially transitioning from standstill to motion and at crawl speeds. The root cause is the interaction between the i-Stop system and transmission control logic. Software updates have partially resolved the issue.
Symptoms: Shudder and jerk when pulling away from a stop, clunking between 1st and 2nd gear, unexpected forward lurch when rolling
Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Recall: PHEV Drive Power Loss Software (CX-70 / 7024J) NHTSA recall 7024J (Nov 2024) affects MY2025 CX-70 PHEV vehicles together with the CX-90. Faulty PCM/ECM software can cause drive power loss in EV mode. Mazda performs free software updates. Symptoms: Sudden drive power loss in pure EV mode, check engine light, vehicle enters limp mode | Low | |
| Recall: Inaccurate Fuel Gauge — Engine Stall Risk (7825I) NHTSA recall 7825I (Sept 2025) affects approx. 16,056 MY2025 CX-70 MHEV vehicles. Ethanol in fuel reacts with the fuel sender circuit board, causing the gauge to show remaining fuel when the tank is actually empty. Mazda reprograms the BCM free of charge. Symptoms: Engine stall despite fuel gauge showing remaining fuel; vehicle cannot be restarted after stalling | Low |
