At speeds over 20 miles per hours there is a “flapping” noise that sounds like a bag or piece of paper that is blowing in the wind. Although I don’t know were the noise originates, I can hear it clearly from the driver’s side b-pillar. It is incredibly annoying and greatly diminishes what is otherwise a solid entry, level vehicle.
On 3/19/23, as I was driving on a dry, straight, two lane road at the posted speed of 40mph, the car began to try to steer into oncoming traffic. I had to exert moderate force to keep the car in my lane. This continued continuously for about 1/2 mile. No low tire pressure indicator lights were illuminated, however the lane assist icon was on and green, indicating normal operation. Just as I was go...
The contol post for lights, turn signal, and high beams is too sensitive. To control the lights, you twist the top of lever. To turn on turn signals, you flip the lever up or down. To turn on brights, the lever goes forward. To turn of lights, the lever is pulled back. The issue..... If you have brights on, when you pull lever back to dim lights, the top automatically twists to shut off the he...
Having been complaining about a noise from under the front right tire, I was initially told it was a little piece of plastic and that got cut off.

The steering wheel column does not have a lock therefore someone broke into my car and tried to steal it and destroyed it, also no alarm went off when this happened.
I was driving 60-70 miles an hour for 45 minutes then car lost all acceleration and engine light came on. I pulled over immediately turned the car off. Turned it back on drove 1/4 of a mile and same thing happened. I pulled over turned car off and had it towed to the dealership.
Vehicle failed to reduce speed effectively while trying to avoid a collision with another vehicle during a left turn, which then caused the vehicle to turn widely and collide with the curb.
Vehicle has less than 4000 miles and throttle body had to be replaced
On the way to work, I had the brake pedal pressed waiting for a traffic signal to change. After it changed to green, I released the brake pedal and depressed the gas pedal, only for the vehicle not to move forward - as if the brake was still being applied.
