Hyundai Elantra battery drain problems

Filed Nov 25, 2025 · Electrical · VA

Low pressure oil light did not come on until the oil drain plug had completely fallen out. Once the light came on, the vehicle was slowed and came to a stop on the side of the highway within 2 minutes. The car completely shut off as if the battery were dead. It had to be jumped in order to put the car into neutral for the tow truck. The safety issue is that the hwy we were traveling on is 70mph. At no time, did we receive a warning until it was almost too late. The car is currently at an auto repair shop as the engine is most likely catastrophic and due to the car having no power, they want to replace not only the engine but also the 12 volt battery and it's module. The low pressure oil warning should have come on way before the plug completely fell out and the battery should not be dead. The mechanics can't even fathom why an engine would fail quickly and drain the battery as well.

The engine bay of my car caught fire due to the abs pump and module not turning off. I bought a part but never opened the box because I received a piece of mail stating the recall of that exact issue that they would replace all parts damaged. Which they didn't just installed their relay After Hyundai recall 188 was completed, my ABS pump failed. I believe it was caused by continuous power being applied post-shutdown — the exact defect the recall was meant to fix. The dealer performed an inspection but misrepresented the results and refuses to replace the damaged component under recall. This ABS pump failure is a direct result of the original recall condition — or a failed installation of the relay fix — which continued to keep power applied to the pump while the vehicle was off. This is the exact scenario the recall was intended to prevent. If the failure is caused by that condition, Hyundai is still responsible under recall. The facility which did the recall falsely recorded the mileage on my vehicle as to void any "warranty" associated with the recall as the car hasn't been driven since the module was replaced. I also instructed the diagnosis team of Wesley chapel Hyundai to keep my battery unplugged due to the parasitical drain in order to protect the battery from being dead celled and now I have to replace the battery as well. They also illegally opened a mailed box I had in my car with a part I bought prior to the recall being mailed out which I never took out of the box nor did I open the box and it was fully sealed which is a federal crime. I opened a case in which Hyundai denied helping with this faulty service and are refusing to provide me documents Case no. 41355389.

My brake lights are not going off when I take my foot off of the brake pedal. I have had to start disconnecting the battery cable so it will not drain the battery. I stop lamp switch replaced when it was recalled. And the steering wheel tilt does not stay in the high spot it falls to the lowest position.

Brake Lights, constantly on. The vehicle, while driving, the brake lights come on and do not turn off. you must force the pedal all the way down, to, sometimes, turn them off. while driving, the lights being on, disables the ECS system, and Cruise Control. while the vehicle is parked and off the lights stay on, unless you depress the pedal, this causes power drains and dead batteries. if the lights do not work, this is a hazard to drive at any time of day. lights will also come on while car is off and has been off for some time.

When driving at night, sometimes the headlights and taillights will shut off leaving the car totally in the dark. This is a SEVERE SAFETY ISSUE as you can no longer see the road and other cars cannot see you. The problem appears to possibly be associated with the light switch, as you can jiggle it and get the lights back on. Also related to this problem of the lights shutting off is the fact that occasionally the lights will come on long after the car has been parked in the garage, which tends to drain the battery. After experiencing this problem, I checked the internet and found numerous other cases of Hyundai Elantra owners reporting the exact same symptoms, so it seems to be a somewhat generic problem. Hyundai’s service department has been unable to isolate the problem on my car. The problem happens randomly and is infrequent but serious when it happens. It has happened approximately 10 times over the past two years.

My brake stop pad broke, causing my brake lights to remain on constantly unless the fuse was pulled. This caused battery drain and safety issues on the road. This issues appears consistent with the recalls for the 2013 and 2014 Hyundai models with stop pad recalls.

It appears the parking lamps stay on when car turned off while headlights are in AUTO. This leads to unintended battery drain leading to unoperational car. Per Owner's Guide: The system automatically turns off the parking lamp when the key is removed (remote key) or when the driver turns the engine off (smart key) and opens the driver-side door. This does not meet the Owner's Guide's language. Dealerships and inspection services did not confirm/reproduce this. There are no warning lights or indicators of this.
