My hyundai Matrix1.6 petrol has intermittant starting probs-but always runs sweet ehen started. Dealer diagnostics comes up with no faults. Can you advise?
The matrix is not listed under your model list - probably because its sold in England under a different name. I've listed it as a Sonata in order to access your service
Answer from the uk.you will only have a problem showing up if the engine management system records a fault within that system, so, the only solution is, if you have remote locking,change the batteries and use to unlock car not using the key.or if no remotes,change keys on a regular basis.(they are coded to the car) do not use grey (service key) only 2 x black keys supplied with car....check handbook re keys....
