general problems of the 2010 Hyundai Genesis

Electrical battery draining replaced battery in oct 2023 within 1 to 3 weeks no power battery dead . Cannot find what is drawing power that is draining the battery.

Vehicle suddenly loses acceleration and drops to a maximum speed of 20 mph. Check engine light turns on but goes away after shutting down the car and leaving it on standby for a few minutes. Occurs every few hundreds miles. It's happened while the car is in motion, both on the street and highway.

Headights turn off for several seconds while driving then come on again eventually. Both headlamps go off together. Headlight switch in manual on position, not the auto on/off position which I do not use.

Car seems to have electrical issues it just shuts off etc just found out I purchased a lemon odometer rollback.

Engine cranks normally attempting to start. When failed to start, the �start� button is pushed to stop the attempt. Tried again. Took 3 attempts to finally start. Once started the engine revs at high rpm�s. When put in �d� the car lurches and accelerates without pushing gas pedal. If the car is turned off after starting and restarted, fast acceleration is eliminated. Car has ultimately started, but the fear is it will get worse and ultimately fail to start stranding the driver. Car runs perfectly in normal driving on the highway. This has occurred almost daily for 90 days. Hyundai service: taken to Hyundai on two occasions. They say they could not duplicate problem and no computer error codes generated. Stumped! can do nothing if problem can't be duplicated by service tech! keeping quiet? new condition 4/26/18! car has shut down twice at a stop light, 4/26 and 4/29. Fear of shutting down while in traffic as reported in user forums. Hyundai user forums: dozens of owners disclose that the problem is widespread across years and models. Report that Hyundai denies there is an issue with problematic starting and stalling at low speeds and high speeds! owners report fear of serious accident if the car stalls on the highway, entering traffic or making turns across traffic.

Tl the contact owns a 2010 Hyundai Genesis coupe. While driving approximately 20 mph, the vehicle lost power and restarted after one attempt. There were no warning indicators illuminated. The vehicle was not diagnosed or repaired. A local dealer was not contacted. The manufacturer advised the contact that there were no recalls and a case was opened. The failure mileage and VIN were unknown.

The tire pressure monitoring system (tpms) displays erroneous tire pressure readings during cold weather climates despite having the correct psi or adding air to reach an ultimate psi reading. This has been an issue with other models of Hyundai vehicles with the tpms feature according to other owners.

The navigational/radio/antenna system completely shutdown without any power ranging from 2hrs to a full day. I also have researched that other 2010s of this make & model has experienced the same electrical issue just as well.

The brake lights on the 2010 Hyundai Genesis (and possibly other years/models Hyundai vehicles) have various problems with the brake lights failing to work. This is very dangerous not only to the Hyundai Genesis driver, but also for any driver following behind the car. . Read more...

Took my 2010 Genesis in for service. . . Brake stop lights were not working. Replaced defective switch. Took my same car in for state inspection on September 9, 2014, brake lights not working again. Replaced defective switch myself because of 2 hour drive to dealer and the safety issue involved with driving vehicle. Something needs to be done! these switches should not fail this often. . . . This is a very serious safety issue. We don't know how long this switch was not working since there is no way to tell when you are driving the vehicle. . . Thanks! john davis.

The contact owns a 2010 Hyundai Genesis coupe. The contact stated that while driving 80 mph, the steering seized and the engine rpms increased greatly. The contact also mentioned that the traction warning light illuminated intermittently. The vehicle was taken to a dealer where the mechanic stated that the ecu failed and the abs control module would need to be replaced. The vehicle was not repaired. The manufacturer was notified. The failure mileage was 78,758.

The 2010 Hyundai Genesis coupe has been defective for a few months now. It will abrubtly shift from 3rd to 1st and from 5th to 3rd by itself. It will also not accelerate when you need it to. I was recently almost involved in accident because of the shifting issues. I have contacted Hyundai several times and they refuse to assist me. What are they waiting for, me to die in accident or something?? I want something done very soon or I will get legal counsel and they can speak with them.

This vehicle has a feature where the door mirrors angle down when the car goes into reverse, and then comes back to normal viewing position when you change to any other gear (e. G. Park, drive). Intermittently, one mirror (driver or passenger) does not come back up. The driver will not likely notice the mirror not returning to it normal viewing position until he uses the mirror again, like when he changes lanes. I have had this happened almost a dozen times to me. I have almost side swiped other drivers on three occasions. I have been to the dealership nine times so far, but they have not fixed it. It is hard to diagnose because it doesn't happen often. Many other Hyundai Genesis owners have seen this issue. . Read more...

While the car is warmed up and at operating temperature, the rpms will "hang" (hover around 2500 rpms) for 3-5 seconds before returning to idle.

Since purchased used from a Hyundai dealer in 2011 with just 11,123 miles & full warranty, this vehicle has had "intermittent operation of the push-button start feature, intermittent ability to remove the vehicle¿¿s shifter from the park position, illumination of the ¿esc� (electronic stability control) indicator lamp in the instrument cluster, intermittent interference with operation of the cruise control feature, or intermittent operation of the stop lamps" as cited in campaign 110 released by Hyundai on March 29,2013. I have brought it to the dealers service department on 11 separate occasions, for the above listed issue -to two separate dealers- and while both utilized the Hyundai warranty to the fullest extent, to replace everything from my radio, to transmission modules, to wheel cylinders, none of these issues fixed the problem. When I spoke to Hyundai last week regarding recall campaign 110, I was assigned a case number, but I received a call the next day that my case was being rejected by the regional office. When I brought it to the dealer for the recall repair this weekend, they insisted that they would have to charge me for the visit, despite my complaint being the one listed in the recall. I feel that Hyundai should honor their recall and address this problem in my car at their expense until they rectify the issue cited in the recall, despite the faulty part having been replaced through my factory warranty multiple times, and prior my receiving notice of the recall. Hyundai motor corporation should do what is required to get the car they sold me to be in safe operating condition, and they refuse to do so.

2010 Hyundai Genesis 3. 8l v6 w/ premium navigation package (touchscreen): bluetooth connects to phone even when accessory power is off. The following was observed with or without the Smart key: 1. Every time a door is opened, or the remote is used to lock the door, the bluetooth gets connected; 2. Once inside the car, the bluetooth keeps connected without starting engine or turning accessory power on: 3. Step out of the car, close the door, and wait a minute or so, the blue tooth disconnects. Cell phone becomes useless in these situation unless I: 1. Turn phone's bluetooth off; or 2. Start engine or turn accessory power on to use car's speaker and mic; or 3. Move away from the car, 20' or so; or 4. Step outside, close door and wait for a minute before using the phone -- all appear safety hazard in an emergency.

This is a recurring hesitation problem. I first noticed this when making a turn into traffic. The hesitation is significant. In some cases there is an acceleration pause of 1-2 seconds. This does not occur every time I accelerate but its lack of predictability is a problem in and of itself. I have come close to being rear ended because the car would just not move when I pressed the accelerator. Also, when the car windows are up and the car sits in the sun for a few hours the central nav and communication system over heats and will not function until it cools off (maybe 20 minutes). In the meantime, back up camera does not work, temperature controls do not work and the bluetooth system does not function.
