The 12v system in my vehicle is defective, resulting in the vehicle failing to operate. Since I have only operated it about 4 times, i am unable to state whether the issue would occur while the car was being driven. I have had the car checked by the dealer twice, and it is now at the service department with an unknown date for "repair". The diagnosis from the second dealer service department directly conflicts with what the first dealer service department said. Additionally, I have discovered that this is a known issue with this vehicle model, and Hyundai has failed to address it. I have filed a formal complaint with Hyundai, as the vehicle is still under manufacturers warranty. Incidentally, there is a newly issued recall that I suspect is related to the 12v system, as well.

This is a follow up to complaint number 1# 1360258 submitted in Sept. In particular, I have had multiple dealers replace a water pump and related assemblies for a total of 3 replacements since Aug. This was their effort to deal with the electrical system issues that have resulted continued incidents of erratic and uncontrolled application of the regenerative breaking (not by driver), shutting off of any ability to accelerate the car while driving, and complete shutoffs of the car while driving on freeways, I.e. all lights off, no response from instruments except for breaking to a stop. I realize you may be short handed dealing with complaints, but I haven't received any contact since first reporting this and was wondering if I should expect any" or is this only once you have so many related complaints to investigate? or perhaps you need some more verifiable documentation of the events" thanks for your help.

I have had 4 incidents so far over the last month, all lasting under 5 seconds. In each case, the regenerative braking switches to a different level without any input from the user. This presents as what feels like a level 3 (strong) braking when none was on and no foot is near the brake, or if the regen braking was turned on (in one case to level 1), it shuts off momentarily. During these incidents, the behavior is also irregularly changing between for example hard breaking (level 3) for a second and then fluttering irregularly between hard and low levels. In one incident, the car completely shut off (and stayed in neutral) after an incident happened while accelerating from a stop. The car then glided to the side of the road where I was able to restart the car as normal. In each case, the incident occurs while in motion, not touching the brake pedal but may be currently set on different levels of regen braking (it's happened both in level 0 (none) and 1 (low). The behaviour is not however trigger by manally changing the regen level but seems to just spontaneously happen while smooth driving. Most cases occurred on city streets but one occurred on a smooth highway at about 60mph. None of the incidents have created an accident as I was not very close to any car in any case. I do have two invoices from separate car dealers looking at the problem. In the first case, they could not find any error codes but they found the water pump was leaking and replaced that (per a tsb). Following another incident I took it to a second dealer who also did not see an error code nor could find a problem. This, even after the "ev" warning light came on for a full drive two days previous.
