4x4 on demand TOD?

Post by paul243 » Mon Feb 05, 2018 9:05 pm

Hi,
I am considering changing my Kia Sorento XS for a Kodiaq 4x4 petrol Edition.

The Sorento is known to issues with the "Torque on Demand" (TOD) system where power is supplied to the front wheels when the rear wheels are detected to be slipping,ie. moving faster than the fronts, Unfortunately Kia messed up the management of the system resulting in a large number of owners (including me!) experiencing severe drivetrain problems, .Even a 2-3mm difference in tyre wear front to back made the car almost impossible to drive.
To overcome this I fitted sophisticated switch to overide the system allowing me to choose from TOD, RWD only or 4WD.
My query is, am I going to experience the same problem with the Kodiaq? Is it the same system?
If so, It's a deal breaker and I'll look elsewhere.
Many thanks for getting this far!
Paul

Kia uses the Dynamax AWD system and the Kodiaq used the 5th (latest) generation Haldex AWD system as do many SUVs, even the early models of the Range Rover Evoque used Haldex.

Not sure the pro’s and con’s of each system but Haldex seem to have a good reputation. I have not seen any uneven wearinntyres however I think someone commented of suffering from this on their Kodiaq but was in the process of getting all the wheels aligned.
It's a 'Kodiaq' and not a 'Bear' unless you are 5 years old.

Any uneven tyre wear front to back was the cause of the the drive train "judder", it was necessary to rotate the tyres to ensure the newer tyres were on the rear,but I still had problems until I fitted the switch to run in RWD unless off road.
Would be interested to hear of any similar problems with the Kodiaq, although it's early days

Might have been me. Dealer reckons they're the same wear but sounds like BS to me - I'm not blind. Will get them aligned if the wear gets worse.
