I would think after the second alternator they would start looking for the real problem. Unless the extended warranty does not pay for diagnostic time. You may have to take it to a shop that focuses on electrical systems to find the real issue. Or pay the dealer to troubleshoot it.
The brake light recall you got in the mail should fix the ESC light.
HYUNDAI IS RECALLING 532,633 MY 2006-2007 ACCENT, ENTOURAGE, SONATA, MY 2007 AZERA, ELANTRA AND SANTA FE, MY 2005-2007 TUCSON AND MY 2007-2008 VERACRUZ VEHICLES. THE STOP LAMP SWITCH IN THE AFFECTED VEHICLES MAY MALFUNCTION. A MALFUNCTIONING STOP LAMP SWITCH MAY CAUSE THE BRAKE LIGHTS TO NOT ILLUMINATE WHEN THE BRAKE PEDAL IS DEPRESSED OR MAY CAUSE THE BRAKE LIGHTS TO REMAIN ILLUMINATED WHEN THE BRAKE PEDAL IS RELEASED. A STOP LAMP SWITCH MALFUNCTION MAY ALSO AFFECT THE OPERATION OF THE BRAKE-TRANSMISSION SHIFT INTERLOCK FEATURE SO THE TRANSMISSION SHIFTER WOULD NOT BE ABLE TO BE SHIFTED OUT OF THE PARK POSITION. IT MAY ALSO CAUSE THE ELECTRONIC STABILITY CONTROL (ESC) MALFUNCTION LIGHT TO ILLUMINATE, AND IT MAY NOT DEACTIVATE THE CRUISE CONTROL WHEN THE BRAKE PEDAL IS DEPRESSED.
The stop lamp switch is used to judge if the acceleration system is abnormal. The stop lamp switch contains two switches monitored by the PCM. This is all covered at the dealer.
The stop lamp switch contains two switches monitored by the PCM. This will cause the issue you are having. It will illuminate the engine light also and cause the transmission to go into limp mode which is what's happening. Have replaced many for this same exact issue. This is what needs to be done next. The engine and ESC light come on together.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate

Mine had a *bad*, but intermitent engine shudder (like it was running out of gas) between 30 and 40 mph. After 3 trips to the dealer, it finally did it in front of them. It's quite dramatic, so they admitted that I wasn't just bringing it in for fun and started guessing what was wrong. They found a TSB that recommended starting with one of the O2 sensors, which fixed it perfectly, immediately.
Sounds like yours isn't your engine - but I thought I should say something just in case.
I had this exact same problem...turns out it has to do with a recall having to do with the stop lamp switch. I took it to the dealership and it only took about 20 minutes form them to fix it.
Hyundai is recalling 531,894 MY 2006-2007 Accent, Entourage, Sonata, MY 2007 Azera, Elantra and Santa FE, MY 2005-2007 Tucson and MY 2007-2008 Veracruz vehicles. The stop lamp switch in the affected vehicles may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause the brake lights to remain illuminated when the brake pedal is released. A stop lamp switch malfunction may also affect the operation of the brake-transmission shift interlock feature so the transmission shifter would not be able to be shifted out of the park position. It may also cause the electronic stability control (ESC) malfunction light to illuminate, and it may not deactivate the cruise control when the brake pedal is depressed. Any of these malfunctions, alone or in combination, may lead to a crash. Dealers will replace the stop lamp switch free of charge. The recall began on April 23, 2009. Owners may contact the Hyundai Customer Assistance Center at 1-800-633-5151. This recall was the result of a Preliminary Evaluation conducted by the Office of Defects Investigation.
Tim,I would take you Veracruz to Sears and ask them to show you a Michelin set. They will tell you what the proper size is.
The Michelin is a little more money but its the best tire.
I hope this helps you.
Don't know if this will help but once had a Buick that kept doing this. Took it to the dealer several times but couldn't find the problem at first, finally replaced a small spring in my cruise control and that solved the problem.
Keep taking it back to the dealer until the fix it or give you a new car. Not that it's an immediate safety issue, it's just something that's supposed to be functioning properly. They have to address it because cars are legally required to have TPMS systems for safety. If a safety mehanism fails in your car, you can claim it is a safety issue. If you keep having problems with the TPMS light, you'll eventually ignore it. Then one day you'll have a tire going flat and you wouldn't know it.
