I have spent over thousands in 2024 in a small amount of time, going to multiple shops, trying to figure out issues. I have been told these models are known for having ecu and electrical issues. My car will not set off any codes. I have greatly maintained my vehicle. I have had my keys reprogrammed, 2 new batteries, 2 new alternators, all new 6 fuel injectors, new map sensor, all new spark plugs and plugs, had my engine and transmission inspected, and when I am in traffic with my kids in the vehicle the immobilizer will set off and bog my car out in traffic and highways. This computer and electrical system is horrible and dangerous. The electrical is parasitic draining my alternator and battery although I have replaced twice in 2 month. No shop can figure out what is wrong with the ecu and electrical. It is draining my pockets, and putting my children and myself at saftely risk. I have done extensive research on this issue. I have seen many people, same car, same issue. Please help. My car will turn on and run fine. Put me in limp modes and even just bog out in traffic. I am very concerned.
I visited mission hills Hyundai located at 10240 sepulveda bl, mission hills CA 91345 on Jul 31, 2024 for recall after appointment. I waited 2 & half hour, and Hyundai told me the recall service completed but not done. It was perfectly lying. Hyundai explained my car's break disc has problem and cut it and then put together, but only done for resurface. They charged $824 as a labor. Please confirm them and recall service was not doing even Hyundai sent recall service letters many times. Hyundai service is not good. Thank you.
There is a code that comes on my car, makes the engine light come on then it goes out on its own . And every year it’s back on same code. Has been happening for years . I took it to the dealership 2xs for the same reason each time they said nothing was wrong cleared the code and the engine light went out. This year being the 9th year having the vehicle the engine light kept coming back on every day after it was cleared and nothing found. So the happy Hyundai dealership ship said leave the car overnight and see if the engine light is back on and if so he can see then what the issue is because it won’t be historical. I paid $212 for diagnostic, and then a few days he said leave overnight. He discovered that the throttle body had an issue and suggested cleaning. But the car goes in limp mode and I couldn’t accelerate but 20-25 mph. The first 20 mins of driving every day. Then it takes off. He determined that an accelerator pedal position sensor was bad. And I went years without any one diagnosing this. My car only has 34550miles approximately. And it’s almost 9 years old. 34k miles a sensor shouldn’t be bad that soon. The codes were p0651/ and p2106. And now in 2024, someone finally figured it out. But now it’s been almost 9 years and I’m paying $900 or 1k for replacement when it was clearly something wrong years ago . Undiagnosed.
Vehicle would not shift up to the next gear and and started attempting to shift but failing every time as it passed 2000 rpms. Incident happened while passing another vehicle, after an extended time of vehicle not being able to accelerate while attempting to pass the brakes had to be applied in order to avoid a collision with an incoming vehicle. The vehicle later failed completely and all power from the engine was lost and started rapidly decelerating then finally came to a complete stop. Instrument and electric power was still on but there was no power from the engine. Vehicle would not move for about 15 minutes, then it finally had limited power to 45mph.
My car was perfectly operational but suddenly during regular driving on the 101 highway it showed solid check engine sign. I checked the error and it read p0880 I had taken my car to the Hyundai dealer (keys) where they diagnosed it as tcm internal failure and recommended changing the tcm after paying for the part and installation ($994. 00 and $162. 00 for diagnosis) the dealer installed the part and came back to inform me that the issue persists after part's installation and that they are going to work with the electricity to fix the problem. Dealer informed me that they shall work on the circuits but not with any transmission problem. As this issue happened with regular use, I believe it to be manufacturing issue that must be carried out and fixed by Hyundai.
My vehicle showed solid check engine light while I was on 101 freeway and after exiting to city road I could park and read the error code "p0880 power input to tcm", I reported the issue to Hyundai dealer and they diagnosed the issue as internal tcm defect. Dealer replaced the tcm but that couldn't fix the problem. And they just released the car as is. After a short while my car had become unable to reverse, and when set the gear to reverse, my car moves forward to make a very life threatening. I called Hyundai corporate office but they didn't help. Now, I cannot drive my car because it is unsafe and because because I'm not a mechanic to diagnose the problem while the dealer and the corporate don't help. I found out that the model of my car is a subject to recall for gear problem which is exactly what I face now. It seems that both of the dealer and the corporate office are aware of the issue in this particular model but they did not even mentioned it to me until I found it by myself. A car like that is unsafe for me to drive because it runs forward only even when the gear is reverse and if stops I cannot even push it backwards. A car with this defect is dangerous for my community. Please help to force that company either replace the car for me, repurchase or repair it to full operational status. .
On June 2, 2017, I was attempting to park my vehicle in a parking stall at a minimum speed of 5-8 mph. Suddenly, the engine revved up, instrument panel flashed and radio changed stations. When trying to brake the car, the brakes did not engage and I subsequently hit a wall. The airbags did not deploy. When the ealer came to get the car, the individual picking up the car indicated something was wrong with the breaking mechanism. However, the dealer and manufacturer says nothing was wrong with the car but won't provide the details of the report.
The contact owns a 2015 Hyundai Genesis. The contact stated that while driving at approximately 40 mph, the contact felt the vehicle was rear ended and the vehicle launched forward. The vehicle was taken to the dealer where the failure was undetermined. The vehicle was not repaired. The contact mentioned the second time the failure happened, the contact almost crash into another vehicle. The vehicle was taken to the dealer multiple times and the failure was undetermined. The manufacturer was not notified of the failure the approximate failure mileage was 21,000.
I owned the car for 9 months and never had a problem in the rain. It was raining and my car safety lights started flashing telling me that front collision warning was not working, lane departure warning was not working, blind spot detection was not working. And to check aeb system. Hyundai told me that although it worked fine for 9 months, that the safety features may not work in the rain.
