The front fascia has large open apertures with no protective mesh or screening, leaving the condenser, radiator, and other heat exchangers directly exposed to rocks and debris. The condenser face shows multiple debris strikes, with one impact puncturing the core and causing complete refrigerant loss and…

   The engine would not engage for 4-5 seconds when pulling out of my neighborhood. Gas pedal was all the way down and after a delay, the car rolled forward as if trying to start in 2nd/3rd gear. I am a cautious driver, but this is an unsafe scenario when pulling out into traffic.

   I've had consistent issues with the vehicle accelerating and shifting. These include sluggish acceleration, loss of power and sputtering when we've come to a complete stop and starting to move again. We've almost been hit by other vehicles at least over 20 times because the vehicle has failed to accelerate when pulling into a roadway. The car hesitates during acceleration regardless of how much I push the gas. Once it starts to go, it feels as though the car can't shift from…

    The vehicle hesitates and does not accelerate immediately from a complete stop. This occurs more frequently when the car is on a slight incline. The delay in acceleration creates a safety concern, especially when attempting to merge into traffic or pull out onto a roadway. I have reported this issue to the dealership multiple times, but they have not taken action because they have been unable to reproduce the problem.
