I'm certainly no Hyundai tech, but the computer may be storing a "soft" code from this issue, so a visit to the dealer might pay dividends. If you're still in warranty, what's to lose but a little time?No, still in the 5 year, 60k mile warranty. But that will not be worth crapola. It is far too intermittent! All they will say is "no problem, works just fine"! It is up to me, I can see that already.
The operative word was "MAY". I'm not sure if an off the shelf OBD reader is the same and has the same capabilities as what a dealer uses and might be able to access.If that is true, that it stores a soft code, wouldn't I see that when I scan with my OBD II reader???
I think that's true with a lot if not most cars. I had a VW Passat and I got the OBD diagnostic software for my laptop. With the usb to OBD cable and plug into the car's connector I could get diagnostic codes for the V6 and all the vehicles other subsystems. But to actually make changes to any of these components (other than clearing fault codes) required taking the car to the service department as their full system could read and make changes plus even upload new software to the control module. The changes I'm talking about are the ones similar to our cars, like reprogramming how the doors lock at speed etc. Of course on the Passat there were a lot of other functions that could be set or altered (got to love premium Euro cars for all their complexities).The operative word was "MAY". I'm not sure if an off the shelf OBD reader is the same and has the same capabilities as what a dealer uses and might be able to access.
I know my friend who works on Nissans has a CONSULT like the dealers use, but there are some things they can access that he cannot due to the costs of the software and the capabilities of his machine. In other words, the dealer's diagnostic tools seemingly are more comprehensive. For example, I asked him to reprogram the headlight "auto-off timer" on my 2011 370Z, but he cannot access that area of the computer with his machine as it is currently configured.
I just returned from my local Hyundai dealership (Hyundai of Slidell, where Zelda II and I first met). I went in a couple of weeks ago to have them read the mileage for Zelda's yearly mileage pre-paid card. They said that I had an outstanding recall that needed to be done (some muffler bracket) and that would have to be done prior to issuing the card. So that was done today. I mentioned the cruise issue and told them not to bother test driving it as it is far too intermittent for it to happen for them. I asked them to check the adjustment on the brake switch and read any special Hyundai CC codes that may exist. They stated that the brake switch was checked and was fine and no code in the computer. Just as I was about to then suggest that it could possible be the switch quadrant beginning to fail, the service person said "it could be the switches. I'll order new switches and we'll swap it out". WOW!!!! Not only are they taking my word for it with no evidence what so ever for them to believe I am not just crazy, but proactively just swapping out the switch assembly.
These guys are GREAT!!! They have no doubt earned my continued business and another car sale in the future.
