Beware: Rear wheel drive failure!
When driving at rapid speeds over longer periods of time (1-2 hours), the rear wheel motor overheats and stops functioning. When this occurs, only the front motor still operates, but does so at limited power capacity and hesitates 1-2 seconds upon acceleration, thereby causing a “jerking” motion when you press the accelerator pedal. The problem persists until you stop the car and let it rest to bring the motor temperature back down, then it goes back to normal. However, if you continue on your journey driving continuously at higher speeds (65 MPH or greater), it happens again. Upon further research, it appears that the rear motor electric oil pump malfunctions at higher temperatures and stops working altogether, causing the rear wheel motor to fail. This is a serious safety issue. We have been battling our local dealer service shop as well as our Hyundai customer service case manager for 2 weeks now with no resolution. The dealership shop claims they cannot reproduce the issue and say there is no problem. Other owners have reported this issue on owner forums for both the RWD and AWD models. Those who own the RWD models lose all power to the vehicle! These other owners have also detailed their struggles with dealerships and Hyundai trying to prove the problem and get it fixed. I have logged a safety complaint with the NHTSA and will be hiring a lawyer and filing a lemon law claim if Hyundai does not repair the defective part in a timely manner. There should be a recall for this, but there isn’t.
