Hi all, the CEL came on , so i took my 08 Tucson too the dealer , and they said it was my 02 sensor so they replaced it , a short time later it came back on ! so i took it back. I was then told it was the throttle housing and they had torqued it up and the light went out. Only for it too come back on while going home that same night !! I have called Hyundaiusa and told them i was not happy with this problem , they said they would contact the dealer serivce department . I now have too take it back and leave it while they try and find out what the issue is. Anybody else had this issue with the CEL , any thoughts ? The car runs great apart from it being alittle sluggish on inclines. I have know idea what the code is that keeps coming up when they run diagnositic. I just want it fixed... Thanks in advance.

 

So we have MIL... looking at your service invoice from when you picked up the car, what is the code(s) listed ?? Better be there if they exect to get claim paid by Hyundai USA if it was a warranty thing..

What were the code(s)... don't have them, call the dealer and get them.. they better have printed the GDS screenshot as documentation to the repair ticket, it is now REQUIRED by Hyundai for a warranty MIL concern.

Just had an '05 with Ox sensor codes, TSB for the chassis I had, TSB states to reprogram PCM with #153... This was for a V6...

Forgot,, which engine you got ?? 4 cyl or V6 ??

 

What is MIL and GDS and TSB , its a 4cyl
thanks for your reply,
