Hi everyone,

So I've been driving the M2 GVC for about a month, one thing I notice about this car is that the pickup is sluggish when accelerating from standstil eg. stopping to turn into a road, feels like it's taking quite some time for the car to pick up speed. Sometimes when trying to turn a road, by the time I am parallel with the road the car behind me is already so close.

One other instance is when trying to ascend on steep incline ( ~20° to 30°) e.g. entering multilevel car park, the car seems to struggle to pick up speed. When I depress the fuel pedal a little harder then only it will rush forward in a not so smooth way...

Just wondering what could be done about this?

I'm no car guy. Could it be related to the weak tensioner?

Scenario 1: going up a slope. Light pedal from ground to uphill. So much stress coming from the engine. Have to press pedal harder/downshift forcibly and the gearshift isn't smooth. Sudden rise in torque

Scenario 2: going up the same slope. Same scenario but with faulty tensioner. With light pedal the faulty tensioner will start vibrating and producing high pitched rattling sound. Have to downshift in order to release the tensioner hence the sound gone

I'm saying the tensioner is weak cause it's changed once few months back but now it starts to show symptoms again (initial symptoms before my ex-tensioner started to turn faulty)

Had a similar 'Gearbox issue', not sure yet, still checking tho.

Anyway, it started just after my last free services (3 years), 2 weeks after the last services, when ever I shifted to gear 'Reverse' or 'Drive' there's a knocking sound. It does not occur in 'Park' or 'Neutral' gear, and the sounds basically stops whenever I drive or when the car started moving.

Sent to Mazda, they informed and quote me the following:-
1. To get clear check, gearbox need to be taken out (Labor cost alone Rm750-850)
2. They said it's either torque converter problem (replacement cost RM4K-4.3K) or flywheel (RM650)

Which means, it could be either RM1.4K or close to RM5K of repair.

Anyone faced similar issue? I have check in some forum and in car talk community, there are some who faced similar issue (but not the new skyactiv), most would say either the loose heat shield or the belt tensioner problem only.

Mine is 2015 batch, halogen version. Had the similar situation (three times this I had encountered, car jerked once, rpm dropped and TSC+engine signs lit while driving starting early 2018), the signs went off and car back to normal once engine restarted. Went to my regular local dealer SC in Kuala Terengganu, only told no big deal, they just overwrite the error codes. Since I heard this could be a cronic issue from other M2 members, decided to make an appointment with Bermaz PJ (attended by Mr Kumar) for thorough check-up, ended gearbox issue and have it replaced within few days. Fortunately, still under warranty by few months left, if not 15k to replace iirc. So, better check it up with Bermaz PJ to assure the real issue behind your situation. Best wishes

your car is which year's model?

seems like 2015 model quite prominent with gearbox/torque converter issues.. still under warranty? better send it to SC asap.

Not easy to deal with them. Plus, without proof very difficult to get them to address the issue.

One of the way is, make detailed recordings whenever the issue arises. Take picture, record video.

Of coz the best way is if you can replicate the issue with their technician by your side.

normal SCs would taichi you, only the Bermaz PJ team know what really needed to deal with. If you drop by and have it checked by them, their verdicts are pretty much the ultimate answer to your relentless worries

Just contact the PIC to make arrangment (as you need to leave the "wife" overnight), I already pmed you the contact. Good luck bro

Sounds very fishy to me, when I change my M2 ATF, I bought 4 bottles and they used up 3.75 L, left only a quarter and returned to me. Cost me RM 30 at Jalan kuching.
Better to check the ATF dipstick, to ensure enough ATF being poured in & find another workshop next time

This is the workshop I went, because it was nearby my work place.
Although I'm sure many other workshop are resonable as long you asked the price first and know basic car stuff.
