2015 Hyundai Genesis

The positive battery terminal has a design flaw where it will wholly lose conductivity with the battery post due to vibrations, stress and age. After numerous dealer visits where "nothing was wrong" I began to diagnose the issue myself. I tracked it down to faulty positive battery terminal, which due to the lack of manufacturer availability I had to correct myself. It seems to be such a widespread but "unknown" issue with the entire vehicle model that I made a repair guide on the subject with photos: https://genesisowners.com/genesis-forum/threads/improved-positive-battery-terminal-box.32768/#post-411757 The primary issue at stake is the sudden, unexpected loss of power steering when maneuvering at low speeds. The vehicle will lose additional safety systems when the battery power is interrupted, such as collision avoidance, parking sensors, airbags and even powertrain control in extreme cases. No manufacturer diagnostic codes will ever be set as the systems in the vehicle do not account for sudden unexpected power loss. Problem is aggravated by objects on trunk floor resting on terminal box. The secondary issue is that when a power interruption occurs while the vehicle is in operation, the vehicle will not properly shut down when the ignition is turned off. Rather than unlocking doors and assisting handicapped drivers via the easy exit seat feature, the car completely dies and does not wake back up. Vigorous door slamming or any other large impact to the body of the car will sometimes bring systems back online, by fractionally moving the positive battery terminal. If systems do not return, the driver is unable to lock the doors or open the trunk. Hyundai does not make the positive terminal a replaceable item, rather, it's only sold as a combined part with a $1400 battery cable (plus 8 hours labor). Dealers and owners alike are averse to replace this part for such a high price, when the battery terminal itself is worth less than $20.

While driving the following codes would flash: AEB, BSM, TPMS, Also while the AEB code would flash it would limit my acceleration weather on the highway or local driving. These issues were reported to Hyundai America Corporate and I have a active complaint as well as a open appointment with a local dealership on 1.4.22. Lastly I do have a video of this taking place

Rear passenger door failed to open from outside or inside vehicle. Possible door actuator or module. Two car seats with babies inside vehicle,couldn’t open door. Very dangerous in case of emergency. Vehicle has only 54000 miles, with extended warranty, dealer not honoring the warranty, item(s) not covered. Dealer says it’s wear& tear. Not acceptable, it’s a safety issue.

Upon driving many warning lights light up and make warning signals on the instrument dashboard. These warning lights light up at the same time or in succession and include: check bid system, tire pressure, check engine light, skid control, check bsd system, and others. In addition, brakes become sticky and steering is affected. Worse yet, car slows down on its own as it engages crash avoidance system.

ESC failed. I was attempting to make a left turn from a stopped position at a typical intersection. I lost control of the vehicle as it started to fishtail once I began the turn. Brakes did not respond and I ended up hitting the curb on the outer lane with both front and rear tires. Side curtain and passenger seat airbags deployed. Vehicle is now a total loss. I believe the faulty ESC poises a lot more risk that just a fire. From other reports on genesis forums by consumers like me, this problem with Hyundai's ESC seems to be a common and reoccurring problem. Recall should be updated to include that ESC may fail and makes the vehicle unsafe to drive.

The contact owns a 2015 Hyundai Genesis. The contact stated while the headlights were on the auto setting, the headlights occasionally flickered on and off independently. The contact also stated that the air bag warning light also inadvertently illuminated. The vehicle was taken to the local dealer and was diagnosed with the wiring harness needing to be replaced. The vehicle was repaired however, the failure persisted. The manufacturer had been informed of the failure and informed the contact that an engineer would be sent out to inspect the vehicle. The engineer was not heard from and the vehicle was not inspected. The failure mileage was approximately 15,000.

1.ENGINE WILL NOT SHUT OFF WHEN VEHICLE IN PARK. HAD TO DISCONNECT BATTERY. there was no warning. 2. LKAS warning light remains on. 3. Caution light remains on on the dash. 4. Anti-braking system highlights when immediate car in front of me makes a turn without me being close to it. The first thing the dealer asks is do I have extended warranty! They stated they couldn't get to the repair until maybe Thursday. I'm really afraid to drive my car.
