ABS turns on when accelerating?
« July 08, 2018, 02:10:58 »
Hi all, I just bought a new 2018 i30 sr and ive noticed that under a hard acceleration the car seems to turn on the ABS brakes and then once it gets into second gear it dips and then it starts accelerating as normal, is this normal? (Not entirely sure itís the ABS it just sounds and feels like the car is jolting as if it is turned on).
Thanks

Hi, Ethan. I presume it's an auto. Either way, I doubt that it's the ABS doing that. Point it out to your dealer as warranty concern.

Are you referring to AEB (autonomous braking). All cars modern have ABS (anti lock) so if you are not braking, its not applied. As Gonz said, not correct_ go to the dealer.

And kindly let us know the outcome. Thanks

i dont think its the autonomous braking because it happens when im on an empty road or with no one infront of me, from a standing start when i accelerate faster than normal the from wheels seem to jolt rapidly as if the abs is on or wheel hop is occuring, at this point the car is accelerating slower than usual because its as if its braking and accelerating at the same time, then once the car gets into second gear it dips and accelerates quickly. will let you know what happens tomorrow.

 :welcome: That is an odd one. I've had my SR for 12 months and have done 30K. Never had a hint of that. Definitely needs investigation.  Good luck. The PD seems to be having more gremlins than the previous 2 series!  :Pout:

Sounds like traction control activation to me. Never driven or seen inside a PD but TC to me cuts power and being auto I'd expect an upshift after it was throttled back and a lag before power came back on

Is there anything lit up or blinking when this happens in the cluster?

i didnt notice anything in the cluster but i tried turning traction control off and then both traction control and stability control off to see what would happen anyway. it did reduce it by alot but it still happened

Oh well, shall await the final report then. That's what i would have tried too, isolating the system to see the change.
