Kia Rio Tec ABS Problem

[StoffelOlivier]

Hey guys

I own a Kia Rio Tec 2012 model. Bought it new and received it with just over 40Km on the clock. Currently I have just over 60000Km on the clock. I have an ABS problem and Kia is not taking me serious about the problem. Does anybody know if there is someone I can ask for help to get this sorted. Im just frustrated with the excuses I get from Kia regarding the issue. Thanks

What exactly is the problem with the ABS?

Braking works fine under the normal circumstances. But when you do emergency braking, or on loose gravel, or when the road is wet, the brakes work up to the point when the ABS is suppose to take over when it locks up. The brake pedal will then push up to the firewall and the car will keep on rolling forwards.

That's normal.

ABS works to prevent the wheels locking under braking so that you can steer, allowing you to maintain control of the car. The wheels lock more easily in the wet, gravel or loose surfaces and hence the ABS activates.

ABS will make the stopping distance longer on loose surfaces. Especially the more rudimentary systems.

When ABS activates the pedal feel changes; it goes further down, limp, vibrates, etc. This is different from manufacturer to manufacturer.

In the cars I've driven the ABS makes the suspension shudder and vibrate as if the suspension is going to break. That is however normal, the ABS is sort of jerking the rotation of the tyre to prevent it locking and sliding even further.

Becareful on dirt road, it's extremely easy to activate the ABS. I've done that from turning too fast from asphalted onto gravel.

My Bakkie when I put the Diff-lock on the ABS lights come one

I suppose the ABS disengages when I activate the Diff-lock?

That does not sound normal. Easy, you invite the service manager for a ride in your car, and you show him what happens. If poo comes out, you know he is bul****ting you.

Have a look at this: https://www.youtube.com/watch?v=hwwXukJaTlM

When ABS engages you will feel pulsing through your pedal and it'll sink to the floor like that. That video shows why you feel the pulses. It is the brakes being applied and released at a high rate. The pedal will also sink down because some of the pressure will be lost on the pedal side (long explanation why that happens but it is expected).

Sounds normal, but yes I think they could have at least explained it to you.

As an aside to your comment:
Typically an ABS system doesn't work on a dirt road because all the wheels lock up immediately and ABS can only determine lock if at least one wheel is still turning (eg it can see some wheels are locking up and then brake less on them to prevent locking). The very fact that the ABS still works under those conditions is commendable IMO. They are probably using a very high sample rate...

On snow, gravel, sand or any kind of loose surface your car will brake faster by locking up.

Reason: The wheels dig into the material slowing the vehicle down rapidly.

Enabling a differential lock on a tarred road is beyond stupid, so they likely disable ABS when you enable the differential lock because you would *hopefully* only enable it on a dirt road.

Anti-lock braking system. It is in the name

The only way to prevent locking is to brake less, hence the pulses through the pedal and less braking.

Makes sense. I have always wondered why the ABS lights come on. As they should only come on if they are not working. Figured it switches off the ABS.
