Has anyone had problems with the Kia sorento KX3 2010 with the stability we tow a twin axle Laser 620/4 at above 55mph the rear starts to snake it is fitted with budget tyres all round. Having four new hancooks fitted as advised by my local kia dealer hope
thiS cures the problem any comments will be gratefully recieved.

    Wow 2axlaes, what a post to read just as we're setting off to look at a'15 plate Sorento!

    Hope you get it resolved and post what cured things - just in case ....

    A previous post on this subject stressed the importance of increasing the tyre pressures when towing plus uprating the rear springs will help.Also check noseweight is sufficient.Should be stable at well over the legal limit.There are lots of bushes/ball
    joints on the 2010 Sorento rear end...are any of these worn?

    Hi Trini had 4 new Hancook tyres fitted today running them at 36psi there is a big differance can now increase speed up to 60 mph but still a little bit unsteady when a big vehicle passes not hundred % happy yet but we are getting there so it goes
    without saying budget tyres  are not suitable when towing caravans. Going to fit a set of spring assisters next see how that works will keep you posted.

    Hi,car  tyre pressures are set as recommended by Kia both in the handbook and on the B post of the car,important to note that different years have different settings.I never check noseweight but would expect approximately 85kg.(I have caravanned for about
    40 years and used to struggle to lift the nose,there is no chance now!!!!!) caravan tyres set to caravan handbook pressures.The actual pressures for the 2010 Sorento KX3 I gave in a post entitled "twiching caravan" a few weeks ago

    Hi two axles.....I never did have a problem because I fitted the MAD springs prior to my first decent tow with this car!I acted after reading a number of articles about the 2010 model without self levelling!I must say that the car,solo,felt better with the
    new springs (more like my previous earlier cars).The last time I fitted MAD springs was to a Granada Scorpio and they definitely improved its towing performance!Others on The UK Sorento Forum have stated that there is a definite improvement! I must add that
    I have no connection with MAD!although some would say that I am!(65/70 mph in Belgium is quite common!!!) Let me know how you get on.

    You may need SLS on the 2010 model as the 2012 is not good regards stability with out it.

    Hi xtrailman it is fitted with the self levelling shocks as at is a seven seater begining to think that i have swoped my fiddle for a googah after  having the shogun sport.Just been in touch with peggers and he was very helpfull he suggests fitting their
    heavy duty springs and shockers not self levelling taking the car for four wheel tracking as suggested by my Kia dealer lets hope that works.

    Hi.I fitted the springs myself,it took about 1 and 1/2 hours including getting the tools out!Jack rear end,remove wheels,undo lower trunnion bolt and remove,take out old spring,fit new spring,replace trunnion bolt and refit wheel.I found that a longish lever
    and a second jack helped..I only bought the car at easter so it will be used for towing andother duties for the next 2/3 years!!!!Off to Switzerland in August and I have every confidence that the Sorento will continue to be a suitable towcar!

    We have a 13 plate KX3. Had to pay more than budget for a 13 plate because I understand Kia reinforced the floor plan from Oct 12 and fitted self levelling suspension. However we were still not 100% happy compared  with our old 05 plate series 1. It had
    Nexen 8000 tyres which had persished in the tread so had to replace them with Khumo's. Totally different tow!!! I joke that the new tyres have walls reinforced with tenners but suspect you get what you pay for.

    I have a 2012 Kx2 and have no problems with stability.

    However, I have recently replaced the original tyres with Goodyear's and the difference in ride is incredible. Much smoother ride especially over potholes etc and also it doesn't wander and/or follow any irregularities in the road surface.

    There were known issues with the 2010-2012 model, the ones with the front round spot lights. Its well documented on the Kia owners website. That is why Kia introduced the 2013 facelift so soon after the new model.

    We have a 2012 Sorento which tows our Unicorn Vigo 2 very well. It has done several thousand miles towing without any twitching or swaying.Very reliable car too.

    It does not have SLS as far as I know.

    We are considering a replacemant, possibly a KX3 or Santa Fe as we are thinking about an automatic next time.

    Write your comments here...Its down to price,£ 1400 more for an auto,but we will consider a nearly new one.Our dealer has a Kx 4 auto nearly one year old.Its got all the toys but we can get new Kx2 for less!

    I am very suprised that the MAD springs did not cure your problems!I just back from a holiday in Switzerland,530 odd miles each way....No hint of instability towing at speeds of up to 70 mph (in Belgium).Van and car were well freighted (I did not check noseweight
    but had 10kg Bp  and a 6kg standard Calor,heavy BBQ plus        all the usual in the gas locker,in the boot of the car was a large cool box full of drinks,another Calor 6kg,20ltr of water in the aquaroll,tools etc.The rear of the car never droped from standard
    hight and the outfit rode level! There     must be something wrong with the rear of your car or outfit loading (in my opinion!)

    Hi D S Weetman thanks for reply outfit towed at 70 with SLS changed nothing hoked van up to mine without towed like jelly on a plate waiting for reply from kia uk everything been checked on suspension ie bushes etc by my local kia dealer who are heavily
    involved on my side as the group manager who is a experienced caravaner used is wifes sorento to tow my unit as said with no problems wish i would have kept the shogun sport well peed off but i am now convinced the problem liies with the fact that we have
    not got SLS but will have shortly cheers Two axles.

    As previous I do not personally think that the SLS will cure your problems ( I have been known to be wrong ,many times!) I do hope that it does because the Sorento is a very good all rounder (I am on my third!).To day I towed an empty Swift Challenger single
    axle for 130 miles on motorways,now and again I could detect some unwanted movement (the car is so relaxed that 70 mph catches one unawares occasionally!!!!) but nothing to worry about.I tow many different caravans (apart from my own) which are usually empty
    and each layout tows differently,but I have yet to find one that is "lively" at 60 mph. All the best with the sls and I will be interested in the result.

    Just another thought.....Certainly Witter list different towbars for self levelling and none self levelling...BE AWARE.

    We bought a '15 KW-2 and did experience a savage snake (van has BPW IDC).

    Tyres are as suppiled on car pressure was 35 PSI.

    Towed since then and altho still cautious, towed ok down to Cambs (A1).

    Hi everyone been arguing who is going to pay the £1133: 00 for the self levelling fitting Kia uk says the claim is with the dealer Chippenham Motor company but the say as they did with the tyres that they are not willing to contribute anything what a complete
    waste of time they are totally not bothered now the have there money and Kia uk say that they are  allso not  able to help but in my opinion the book should stop with them they know there is a problem but dont want to admit it. I am now faced with having to
    fit SLS at my expense but as i feel now i could get shut only if i were not to loose a fortune. Will keep you posted on the outcome.

    I have been waiting for the outcome of having sls fitted (together with a different towbar if necessary) with baited breath!.I work (as you may have gathered)for a small caravan dealership (not small caravans!!!!) and like to help our customers with their
    choice of "tug".As previously stated,I am currently on my third Sorento,ranging from 2003,2007 and now 2010.I have had no problem with stability on any of them and the present 2010 KX3 is no exception other than as a precaution fitting Mad springs and harder
    tyres.I only wish that we were nearer(geographicaly) so that I could experiment.Good luck.
