2. Idling or cutting off problems.
3. Frequent misfiring.
4. Noticeable reduction in power.

Why are Rx8 so unreliable?

No, it’s not just one part of the engine, it’s the whole thing, as the Renesis 1.3-liter rotary engine that powers this sports car is known to be a gas-guzzling, unreliable machine. Instead of pistons, the rotary engine uses rotors to operate, and over time, they tend to wear down.

Why do Rx8 engines fail?

The problem is that there are so many different ways for an engine to fail: Excessive carbon buildup accelerates seal wear, causing compression loss (particularly a problem in automatic RX-8s) Excessive carbon buildup unseats the seals, causing compression loss (particularly a problem in automatic RX-8s)

Can you jump start an RX-8?

To begin, pop open the bonnet of your RX-8 and remove the engine cover from the engine bay, followed by the battery cover just below (left of centre). Do the same with the donor vehicle (lift the bonnet and reveal the battery terminals).

What causes carbon deposit in Mazda RX-8?

The RX-8 has a rotary engine which requires apex and side seals to seal off the “combustion chambers” within the engine. As the car is driven these seals will eventually wear down, and carbon deposit is can form on the side of the engine causing leakage between the combustion chambers and changing engine geometry.
