Mazda Mazda3 Common Problems and Solutions
Rattling Exhaust
Problem:
A rattling noise is coming from the exhaust pipe.
Solution:
In hatchback models produced between 1998 and 2001, it’s common for the exhaust pipe to rust completely in as little as two years. If your Demio appears to have this issue, your only option is to replace the entire exhaust pipe and feed system, which you can find on our drop-down parts list.

Broken Windscreen Wipers
Problem:
The windscreen wipers are not functioning at all.
Solution:

All you need is to buy the replacement windscreen wiper relay. Locate the faulty one, remove it, and insert your new relay. Your problem will then be resolved.

Engine Fails to Restart after Idling
Problem:
The car stalls after stopping at idle (i-stop).
Solution:
This will always be a software issue affecting the PCM and the automatic idling restart. It was a sufficiently consistent problem that Mazda issued a recall for all Mazda 3s manufactured between November 2018 and September 2019. You will need to visit a Mazda dealer for a software update.

Unexpected Braking
Problem:
The Mazda 3 stops suddenly even when you have not pressed down on the brake.
Solution:
It’s very probable that the Smart Brake Support system is incorrectly programmed. This problem impacts several Mazda 3 models manufactured between late 2018 and late 2019, which were recalled due to safety concerns. You should take your vehicle to a Mazda dealership for advice.
Difficulty level
Stalling
Problem:
The car stalls while in motion, raising the risk of an accident.
Solution:
The powertrain control module is faulty and is causing an imbalance in the air/fuel ratio. This was a problem for Mazda in 2019 and led to a recall of the Mazda 3. Take your car to a Mazda dealership, and they will be able to rectify the problem.
Difficulty level
Tyre Pressure Light is On
Problem:
A common problem for the 2019 Mazda is that the tyre pressure light remains on even after checking and confirming the pressure is correct.
