Unresolved Recurring Problem / Issue with my Naza Forte 1.6SX

1. Soft buzzing sound everytime i first step on the accelerator pedal, usually occuring around 1000RPM.

2. Harshness when going over bumps / uneven roads / high speeds above 110km/h. Suspension? Rims? It feels like "swaying".

3. Steering turns to the left by itself. Tyre shops "solved" the pulling to the left problem by pumping more air into the left tyres and less air into the right tyres. 32 vs 29. But the steering wheel still shifts to the left when going over bumps.

Yes, you are right, it's just a workaround, not the solution. I have added the camber bold (RM70), but their secret in resolving is varying the tyre pressure.

I was standing beside and observing the entire process. And same same, they consumed lots of petrol driving around, coming back, changing the tyre pressure, and testing again... they repeated the process perhaps 5-6 rounds.

Nope, the one nearby Sunway Tol is only sales center, you need to go further straight to Bukit Jalil direction and you will see the KIA SC on you right hand side after Shell Station.

If last year service pricing is still applicable, 40k km service should be less than RM600. RM8xx is for 60k km service due to replacement of V-ribbed belt. I did my 40k km service at the end of last year, ending up paying only RM48x (2.0SX) coz i didnot change the air filter (using the easy to clean stainless steel Simota air filter) & also topping up just 0.5L of coolant & brake fluid instead of 1L each.

If the dealer charge u RM8xx for the 40k km service, i believe they wanna replace/change the unnecessary items.

which SC(s) are they?

after that just sign the checklist to show that u're ok with the car when delivered to you. do a thorough check, bring a friend along is best to check the lights, spot any dents, paint chips, scratches, etc.

Been using RON 95 on my 2.0 FL since Day 1. My car just celebrated her 1st BD. No problems with knocking. Nowadays it is hard to find a car without a knock sensor anyways...

The biggest problem with using a low RON fuel is the loss of power, especially during hot afternoons or if the engine is clogged and not in tip top shape. Knocking can be induced not only due to compression ratio but external factors like underhood temperatures, air density and engine efficiency among others. If you find that your car is sluggish during afternoon runs and appreciably more powerful at night, that means your ECU is holding back the engine in the afternoon to keep temps in check and to prevent knocking. Changing up to a higher RON fuel will lessen the impact.

Here's how the knock sensor works. It is supposed to measure and detect imminent pre=detonation before it happens, and sends the data to the on-board ECU. The ignition timing advance on modern cars with EFI is fully regulated by the ECU and operates on a closed loop system, relying on data from various sensors from the intake all the way to the exhaust.

Ignition advance is dynamically controlled based on throttle input, IOW as you step on the pedal, as the revs climb the ignition is advanced more and more to compensate for the faster cycle between intake and exhaust strokes. The CVVT system works in conjunction with ignition advance to deliver optimum fuel mixture on demand. Unless the knock sensor is damaged, there is no reason why RON 95 cannot be used in a high compression modern engine with fully controlled engine management (knock sensor and CVVT).

Having said that, knock sensors do have a pre-set tolerance, i.e., if you use a fuel that has a very low RON rating like 88 (example), then knocking could still happen as the engine and ECU were not designed to operate below a certain threshold.

But to sum it all up, I believe there is no harm in using RON95 in the Forte.

Just nw jam at persiaran kewajipan thay time i checked the average fuel consumption on my panel..webt up to 20 l/100km..normal ah?

hi,
im searching for new car collection checklist in pdf form...
remember someone post it here, but couldn't seem to find it.
anyone?

Thanks

Bro are you sure? That looks like a Mazda 3 to me...

Dang My Antenna is stolen... anyone here knows how much it cost? Any replacement unit out there.. I heard original part are "spicy"

My friend's forte (parked outside of his house) got broken into in the middle of the night. Broke the glass and grabbed his smart tag, coins, etc. No alarm, nothing. So the robbers can take their sweet sweet time lol. I think alarm systems (incl. the immob) are necessary. They are annoying for a reason =P

erm.
planning to add a camera at the front bumper and connect it to the HU; activated upon request. anyone know whether is this possible?

Yeap ! I had my first 1000km service at Red Cube too and yeap they are damned slow and not able to fix a very small problem for me as well  . They took 2 hrs plus for a normal service which is ridiculous to me  .

However, I would have to admit that they really have a beautiful show room and a very comfortable waiting area for kia owners to rest while waiting for their cars.

My opinion is; if you just want to get a normal service (no technical problems needed to get fixed) and you get plenty of time to spend then no harm to try Red Cube at PJ, you will enjoy the environment there 

Ha..ha...for safety purpose, even though if manual transmission, u still need it to be in N to start or your car will go forward. You only engage gear 1 or 2 (this also if necessarily) if the clutch cable snapped or u need to push start.

if not mistaken the alarm costs abt RM500, shock sensor RM260.
car still pulling to the left. thinking of sending to 3rd party shop for balancing/alignment. any clue to solving this issue?
