That is true, but from the thread’s title, we know that the vehicle is only 5 years old. As a result, as long as it was purchased as a new vehicle, and as long as it doesn’t have more than 100k miles on the odometer, the problem is likely to be covered by warranty. (As long as it has been maintained as per the mfr’s maintenance schedule)

Is the OP aware of his warranty coverage?

Also… Is the Check Engine Light lit up?  
🤔

The turbocharged engines tend to hesitate quite noticeably in hot weather.

Driveabilty complaints are generally not covered by the powertrain warranty, the Powertrain warranty covers the lubricated parts of the engine;

_"The items covered by the Power Train Limited_  
_Warranty include:_  
_- In the Engine: Cylinder block, cylinder head and_  
_all internal parts, timing gear, seals and gaskets,_  
_valve cover, flywheel, oil pump, water pump and_  
_turbo charger."_

For example, Today I replaced a throttle body that was not covered by the Powertrain warranty but was covered by the extended warranty.
