I have been asking for my code for months and the head tech at my dealer claims the limp home info in the manual is a misprint and it does not exist. I pointed him to the procedure to set it on the hmaservice.com website and he said he knows it is there and feels they should issue a TSB about it. Has anyone experienced this? Were you given a limp home code? Thank you!

The "Limp home code" is a four digit code that you cycle the key to start the car when the immobilizer warning light blinks on the dash. Described in the Owners’ manual, section 1, page 6.
From the Owners' Manual:
"Limp Home" Mode and Related Procedures If the immobilizer warning indicator blinks for five seconds when the ignition key is turned to the "ON" position, this indicates the immobilizer system requires service. The engine cannot be started without using the procedure below. The following procedure describes how to start the engine using the limp home function (0, 1, 2, 3 as a sample password).
NOTE: You can get a limp home password when the vehicle is first delivered to you. If you do not have a password, consult your authorized Hyundai dealer. 1. To activate the password, turn the ignition key "ON" and "OFF" according to the digit numbers. The immobilizer indicator will blink along with the operation of the ignition key. For example, turn the ignition key once for digit number "1", and twice for "2", and so on. For the digit number "0", you must cycle the ignition key 10 times. 2. Wait for 3~10 seconds. 3. You may set the remaining number of digits by following steps 1 and 2. 4. If all of the four password digits have been successfully entered, turn the ignition key "ON" and check that the immobilizer indicator illuminates. From this time, you have to start your engine within 30 seconds. If you try to start your engine after 30 seconds, your engine will not start.
The system is covered in the shop manual at hmaservice.com, in the Azera section: G 3.8 V6 DOHC /Body Electrical System / Immobilizer System /
The immobilizer system will disable the vehicle unless the proper ignition key is used, or the system cannot read the code in the key, or the system malfunctions.

Gator65, thanks for the confirmation that it exists! I originally went to the District/Regional service manager and then to National in California and received no concrete answers. They always say go back to the dealer and the dealer is useless. Now that I know my dealer is uninformed or ????, I’ll go back up the ladder. It sounds like you have a good dealer. Thanks!

I had it programmed with 4 numbers of my choosing. I sat in the car while the tech used the hand held computer which was attached under the dash. It certainly exists. don
