SUVs Hyundai Tucson Hyundai Tucson ESC Warning Light and Electrical Problems

| I have an 06 Tucson GL 4x4. In the past year I have noticed certain electrical issues come up. For instance my HVAC controls would not respond for a few days and then they started working again. I never took it in because they would eventually work again so the service techs would not really be able to trouble shoot the problem when they are working fine by the time I get it in. Then last month I notice my “ESC OFF” light coming on after I drive for about 5 minutes. When I shut my Tucson off the lights go out and stay out until I drive it again for like 5 to 10 minutes. So I took it in to my dealer and left it for a day. They gave it back to me and said I must have had the switch engaged because they could not get the light to come on or read any codes. So I took my Tucson and drove it down the highway for 5 minutes until the light came back on and then drove it back to the dealer and left it running to show them there is a problem and allow them to check the codes. The computer read a code that the break lights had an error. At this point many small problems came to light. The tail lights were getting a small amount of power. Not enough to light up obviously but if you looked at the bulbs they were very dimly lit. In addition the rear defroster would not respond the cruise would not work now and the stereo power would cut in and out. The third break light also lit up the 5 LEDs on the far right side any time the vehicle was running. The techs called Hyundai and the factory technicians had never heard of such a thing going on. They decided to replace the cruise and brake light module. And I set up another appointment. I brought my Tucson in and they installed the module only to find it fixed nothing. I set up another appointment in which they felt strongly they had isolated the problem. They would not explain to me what the parts they were replacing would be. I was rather upset that I keep having to leave my vehicle with them so they decided to rent me a car. I did not hear from them for the last four days… Today they call me and tell me I will need to continue to drive the rental car for another week or two because the new modules they installed ended up feeding back into the electrical system and “knocked out” more modules? They said they are going to have to wait for a technician from Hyundai to come next week and look at it. Just thought I would share… I have really enjoyed the Tucson but I have never had an odd set of problems with a new vehicle before. The truck only has 17K miles.. | |

I have a 2005 KIA Sportage (same SUV as the Tucson)with the same problem My "Traction Off" light would come on intermittently in hot weather and never in the winter. It also never came on when the dealer checked it out. I plan on driving to the dealer when it happens again and let them check the error code while the light is on. I'm in Iraq at the moment and my wife says she hasn't seen the light come on this summer. It's probably a traction sensor but I started wondering if the traction control worked fine and perhaps it's actually a faulty dash light? Once again, it never came on except in hot weather. |

Replying to: scottie06 (Aug 15, 2007 5:40 pm)  and they ended up giving me 3000 over what all the books were quoting my tucson as worth in the books to make up for all the issues in the past. I will try to update if I find out any information on them fixing the Tucson and find out what is really going wrong.

I have an 06 Tucson Limited with 22k miles on it. I had numerous problems during the 15k warranty period- had a transmission leak at 7k miles & they wound up replacing the transmission (with a "reconditioned" one of course, which means "used"). The sunroof leaked & had to be fixed twice. I've now discovered that I have probs with the dashboard warning lights if I drive for several hours and turn off the engine for only a few minutes. Once, the check engine light came on- and the gas cap WAS tightened. Next time the ESC light came on. Just yesterday, on a long drive, the check engine light came on again after only stopping for a few minutes. The strange thing is that if the car sits a while- hours or overnight- the next time I start the engine the light that was on does not come back on. The first time this happened I used the Hyundai Roadside Assistance (and the guys on the 800 number were absolutely wonderful!) to tow me to the nearest dealership, and they thought it was because I had just gassed up & must not have tightened the gas cap. The other times this has happened I had not just gassed up. Since it only happens on long trips, I'm stuck on the road when this happens and I am losing confidence that this Tucson is safe to drive. Has anyone had this problem- I don't know if it's a short in the sensors or what?

Replying to: kathystucson (Aug 27, 2007 6:03 am) If anybody tracks down the source of this issue, link to a service bulletin, anything like that please let me know! I cannot afford a rental for a week or weeks and the dealer is scaring me it could take that long. As long as the ESC is actually functioning I don't give a flying fig about the light itself at this point. This is not the only electrical type glitch I have. Periodically the car dings when I get out as though I left the keys in (they aren't). Reinserting and removing the key generally solves it but hoping it doesn't go like the ESC light now. I had been chalking them both up to a fluke in that this car came with factory cruise control. But supposedly cruise control is not even available as an option according to the mfr site. Dealer didn't put it in, it came like that and it is Factory. Does everybody with this problem have some sort of option that would effect wiring or put in something aftermarket? The only Sportage I found on the net before the above post with this ESC light business had an aftermarket towing package put in. My ESC light problem started when the weather got hot. But it is cooling off and lights coming on every day now. IF somebody gets it fixed, please share!

Just purchased 2006 Tucson 2 days ago and ESC light came on today. Will copy posts regarding this to show dealer. Will pass on any info. |

| I have a 2006 Tucson, and I, too, am having the ESC light turn on frequently. I'm taking it to the dealer on Monday, so I'll report what they said. I was also the victim of a dead battery this morning. Needless to say, I'm disgusted and ready to dump it after a year and a half. | |
