See above link for information

Unlike p0 codes which are generic p1 codes are enhanced codes. p1999 is cooling system fan circuit which could be a number of things. Start with the obvious what in that system isn't working correctly.

the transmission wont shift gears

Hello, There is not a recall for this issue,but there is a TSB (technical safety bulletin) by Hyundai for this issue that you are having with your vehicle for the code that was set. What this consists of is replacement of the throttle position sensor and performing an ECU software upgrade for the vehicles computer. The process usually takes about 45 minutes to an hour to perform at a Hyundai service department. If you are the original owner of the vehicle or it has less than 60,000 miles, this repair procedure is no cost to the owner. Hope this info helps. Gabe

You describe an issue which should be diagnosed by an authorized and certified Hyundai Technician. Here's what happens when a coil fails: Overload of the drivers in the in the PCM (Powertrain Control Module) as well as the IFS (Ignition Failure Sensor). Did you happen to have a "Check Engine Light" and did you retrieve the DTC's (Diagnostic Trouble Codes) from the PCM (ECU (Powertrain Control Module/Engine Control Unit)? I'm going to assume you had a coil failure.... occurances like this also damage the IFS.. when that happens, usually, it also damages the coil drivers in the computer (ECU/PCM)... this is why I recommend you have it diagnosed by a qualified Hyundai Tech.

Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. The problem you describe is difficult to diagnose without a starting point (DTC). Apparently, the problem is in the A/T (automatic transmission) ... when you cycle the ignition key, this drivability issue also gets recycled until it happens again. Possibility exists it could simply be electrical (repairable) without replacing the trans.

The problem you describe could simply be a wiring/connection problem -- no telling at this point. Now, having written that, my suspicion is the LR (Low/Reverse) clutch or the solenoid (hopfully, just the solenoid).
