Battery Cable Problems of Hyundai Sonata

I pulled into a parking spot and noticed nothing out of the ordinary with my vehicle. When I was stepping away from my car and pushed the lock button there was no clicking sound. I continued into the building and returned to my car a few minutes later and it would not start. All of the lights would come on, but the brake locked up and the car would not start. I attempted to charge the battery which did not work. I unhooked the battery cables for a period of time to reset the lock system and possibly unlock the starting system, which did not work either. It has only been two weeks since I took this vehicle into the dealership to have the computer system updated due to engine failure issues in other vehicles. I purchased this vehicle less than a year ago and it does not show from what I can tell a recall. However I was instructed by the dealership to have the car towed into them so they can check to see if it is engine failure or a number of recall issues that I have not been aware of.

First of all the time and mileage are approximate. We experienced difficulty in turning off the parking/dashboard lights in our 2006 Hyundai Sonata. Flicking the stalk back and forth a few times would eventually turn them off. I asked my mechanic and called 2 local Hyundai dealers and all agreed the only solution is to replace the entire fuse/relay box. After consulting a few Hyundai forums I learned that this was a problem affecting some 2006 and 2007 hyundias and that owners were paying between $700 to $1200 to replace the faulty part. Many owners are upset that Hyundai does not issue a recall. On Monday, January 27, 2014 the stalk stopped working. A call to Hyundai north America not only resulted in no help in finding out which fuse would disable the lights but also assured me that Hyundai seems to expect the life of such parts to last just past the warranty expiration date. I decided to pull out the relay located under the dashboard which turned off the lights (among other things). The next day when my wife left work after inserting the relay back in, she couldn't get out of first gear and slowly things started to stop working such as the heated seat and the rear defogger. Once home, I disconnected the battery, waited a few minutes, reconnected the battery and road-tested the car. Everything worked normal; however, this is the only way to turn off the lights. On Sunday, February 2, 2014 I bought a battery quick-disconnect and wired the other end to the existing Hyundai positive battery cable. Now, while we wait weeks (possibly months) to have the money to get this part replaced, my wife will have to leave work and in a dark parking lot, reconnect the battery using this quick-disconnect tool. While the car sits at home and at her place of employment, it remains unlocked with no alarm, I can provide digital pictures of this along with other complaints about the car.

During operation of the vehicle, when vehicle engine speed drops to approximately 1000 - 1100 rpm, headlights will dim or briefly shut off, radio will shut off, and interior fan speed will drop. This happens for approximately 1 second and is intermittent. From searches of the internet, this appears to be a common problem requiring replacement of the positive battery cable assembly. I do not understand why this has not been handled via a recall, especially since headlights dimming off or shutting off during night driving is extremely dangerous. This has happened on multiple occasions to this car. In addition, probably due to this voltage drop problem, several headlights, brake lights etc. , have had to be replaced. This has already cost me several hundred dollars in troubleshooting and repair, prior to learning about the cable assembly.

I have made five trips to the dealer with the same problem with my 2000 Hyundai Sonata which was purchased from allen turner Hyundai in pensacola, FL and is serviced by them due to it is still in warranty. My car makes a loud clonking sound and then stops and all power goes off. This happens normally when I go over 30-40 mph and has happened while driving 70 on the interstate and almost caused me to wreck on a bridge because I had no shoulder to go off on and cars almost slammed into the back of me. After it shuts down, it takes anywhere from 10 minutes to one hour to start again. It turns over but will not start after this happens. As said I have taken this 5 times to the dealer, this last time they kept it 5 days and found nothing. I had them drive it home. Prior they told me it was a computer error and was fixed, at first they said it was the computer board but then said the boss said it was just "bad battery cables. " and cleaned off the cables. I had a new battery put in. They told me it was the air filter had jumped off the track and just needed put back on. The last 2 times they said the computer read nothing. I asked them about the gas line or water in the gas and they said they check all this, checked crank sensor, changed mass air flow sensor, "bad connection", tightened cable ends per tech line. The last time the invoice just tells me the computer reads ok. I had them drive it for 5 days for 218 miles but it did not reproduce per tech. I am going to get killed in this car and they honestly just don't take it seriously. I am a female and drive by myself alot and it scares me to lose control of my vehicle and for this to happen at night. I just can't seem to get the dealership to take it seriously. Help me.
