While driving from work the car did a quick jerk and the STABILITRAK, ABS AND CHECK ENGINE LIGHT ALL CAME ON ALL AT ONCE. As I pulled into my workplace the car lost power to the engine completely while displaying ACTION REQUIRED ON THE LCD SCREEN. The brake and steering wheel became stiff and it was hard to control the vehicle. It took 10 minutes for me to regain power and control over the vehicle that again after leaving work stopped on the highway.

When driving on the highway at full speed my car suddenly loses power almost causing me to be hit from behind. I then get a Reduced Engine Power warning. Once I get the car off the road, I shut the engine off for a few minutes and then restart it. The car runs fine but the check engine lights remains on. This has happen 4 times this week.

The contact owns a 2018 Chevrolet Impala. The contact stated that while operating the vehicle, a strange odor was present coming from the engine into cabin of the vehicle. The vehicle was taken to local dealer (raceway Chevrolet located at 1510 South 5th St, hartsville, SC 29550) who diagnosed the air conditioning evaporator coil was defective and had leaked freon. The coil was replaced and the failure was remedied. The manufacturer was notified of the failure. The failure mileage was 39,000.

My vehicle has been serviced several times since I have purchased the vehicle. The car will completely shut off when attempting to turn back on after the auto stop turns it off then I have to place the park hit the start switch and restart the vehicle. Also my ac has stopped several times in the vehicle. The ac compressor was replaced in 2019 and had been serviced twice before that happened because it blows extremely low and have to put it on high just for the air to blow. As of today the ac has been going in and out even after the replacement of the compressor and still no one can tell me what's the issue!

I went to the store and came out to leave. I attempted to start my car and the radio came on, lights in the car flashed a couple of times and then I tried again. Then it started making a clicking sound.

Stabilitrack and engine light came on at the same time with a message that said, 'engine power is reduced'. this occurred as I was driving on the highway. The vehicle gradually slowed, but I was able to maintain a speed of 55 mph. I was unable to accelerate quickly.
