Angry 5th and 6th gear gas cutting and stalling

I own a 2018 Mazda CX-3 1.5L diesel vehicle. My car has 85,000 km on it. When driving in 5th and 6th gears, it first cuts the gas and then stalls, lighting up 4-5 warning lights. When you pull over, stop, and start the vehicle, the lights go out and you can continue. However, it happens again after a certain period of time.
Has anyone else experienced this issue and found a solution?

Welcome to the forum


The first question that will be asked is to provide :
All current DTC
All permanent DTC
I/M Monitors status

When was the last service done and what was it.

Maintenance was performed 2000 km ago. All filters, engine oil, and brake pads were replaced.

The warning lights that came on during the malfunction were: lane departure warning light (LDWS), tire pressure warning light, i-stop light, collision warning light, smart city light, and TCS light.



The most recent incident occurred while driving on a long road, and the situation I described several times before repeated itself. Again, while driving at 160 km/h, this time the engine light came on. We drove like that for a day. (I added injector cleaning fluid at the gas station), and then the engine light turned off by itself.

Your information should be reviewed by a service a shop that has a Trained Diagnostic Service Technician with OBDII diagnostic systems and other electronically monitored and controlled systems on your MADA. And from your response this should be done ASAP.

Do not use a shop that only has a basic mechanic. There would be to much guessed diagnosis at your expense.

For a better service shop 1.0 to max 1.5 max hours diagnostics would find and give recommendation to resolve the issues.
