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.

Hello NHTSA administrator, I bought a new Hyundai Genesis in March 2010. Around August 2010, I had a small fender bender in the parking lot. To keep warranty intact on the car, Hyundai insisted that the wiring harness on the car be replaced, which I did for approximately $5000. Since then, I have had multiple electronic items go bad in the car. I replaced some of these at my own expense. But the problem has gotten worse with some expensive electronic components going bad over the last 2 years. In normal circumstances, these components should not go bad over the life of the car, and certainly not at a frequency that they have failed in my car. I attribute these failures to bad/defective job done during wiring harness replacement. But Hyundai has refused to accept responsibility since the car is out of warranty. Below is a list of the bad components, approximate date of the component going bad, whether it is replaced/fixed and approximate expense to fix them 1. telescopic steering wheel--2015--repaired as part of warranty 2. power switch assembly driver's seat--Jan 2016--$236.19--paid out-of-pocket to get it replaced 3. jog dial assembly--Oct 2016--$1031.70--paid out-of-pocket to get it replaced 4. front cabin dome light assembly--Feb 2017--$376.91--paid out-of-pocket to get it replaced 5. smart cruise control--Mar 2017--not replaced--dealership gave me a quote of ~$4500 to replace 6. passenger cabin dome light assembly--Aug 2017--not replaced--$4500 estimate to replace 7. multi disc cd player--Feb 2018--not replaced--$1000 estimate to replace I would like NHTSA to investigate Hyundai for this matter and force them to pay for repairs. As a consumer, I feed cheated and being forced to double pay for repairs - once for the wiring harness replacement and now for all problems attributed to it.

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.

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. www.genesisowners.com/Hyundai-Genesis-forum/showthread.php?T=10483.

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.

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!

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. There has been various factory recalls for the 2010 Hyundai Genesis brakes including one that causes the brake lights not to work due to a brake switch failure: www.cars.com/Hyundai/Genesis/2010/recalls however the particular problem my car and other Genesis owners have reported does not have a factory recall for it, even though it poses the some of the same safety issues that the brake switch factory recall had. genesisowners.com/Hyundai-Genesis-forum/showthread.php?T=3269 the root cause is diode that fails which cause the brake lights not to work. (this is different that the brake switch factory recall.) I don't know how many months I drove without having brake lights. My state inspection was in January 2014. A driver that was behind my car informed me my brake lights didn't work in May 2014. I had my car towed to the dealer due to the danger of driving when the car's brake lights don't work. Apparently Hyundai knows about the issue (according to the above link) : technical service bulletin 09-be-023, stop lamp Z01 diode inspection procedure, appears to describe the location and procedure for troubleshooting of the diode but describes the issue as "... vehicles may experience the stop lamps blinking on and off even when brakes are not applied." Why is there no factory recall for this problem? it can cause serious accidents which could lead to fatalities.

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.

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.
