Camshaft issues/brake to park sensor issue/brake booster to engine vacuum

- Houston, TX, USA

Check engine light lit up on the dashboard. Did not go away, took car to dealership next day. Turns out that the fuel pump system (P & A Fuel Pump & Sending System) was faulty and also needed an ECM update to the programming system. The fuel pump breaking down confuses me because the car will only be 4 yrs old at the end of May, with only a little bit over 31,000 miles on it. This system should not have needed replacing this soon in the cars usage.

Numerous times while driving my car both my son and I have experienced the same issues. Trying to get on the highway and pressing the gas pedal the car isn-??t responding appropriately to the level of which the gas is being pressed. It isn-??t accelerating appropriately. Than at stoplights or just trying to make a left hand turn from a stop position. You take your foot off brake and press the gas to go and it rolls a bit and you-??re pressing the gas to go and the car isn-??t responding. It-??s just sitting there. Like paused. Then all of a sudden the car engages and takes off. It is very dangerous to not have the car respond to pressing the gas. And I don-??t want to get into an accident because I-??m trying to make a turn and get hit cause I-??m just sitting there. Rather than it going when I-??m pressing the gas. I am not getting any codes popping up on the dash. So the dealership has nothing to look at other than me saying this is happening to me and my son. I-??m finding issues similar to this on previous models. But nothing on the 2019 that I can find. And with no error codes registering. But the issues occurring is highly concerning to me. There isn-??t just one date this has occurred. This has happened now many times over the last 6mos.

It-??s gotten so bad the vehicle is stalling out while driving and in busy roads and the highway.

The throttle body charge pipe popped off there was a recall that on this car says it-??s fixed. We replaced o ring and clip on charge pipe drove car. When we sped up to pass a car the charge pipe popped off car shut off. We had to push the car out of traffic. The car would not start. Error code check engine and engine power loss. Three hours under a Houston TX bridge got a tow. Only to be told that the gasket and clip needed to be replaced. Replaced again gm parts, car still can-??t go up hills or sped up. Charge pipe will pop off. The throttle body was checked and the lip on throttle body is still good. But there is too much oil build up on throttle body it appears and the charge pipe can-??t stay on. Causing engine failure. This almost got us killed on the highway. Very unsafe please help.

When trying to accelerate on the highway and merging if I get close to 3 RPM to get up to 60-65 mph M engine light appears on the dash as well as my traction sensor light and my car will no longer allow me to accelerate. Also after this happens it will not allow me to use my cruise control. This has happened multiple times over the last few months. I took it to my dealership to have it fixed twice the first time they could not figure out what was wrong the second time they discovered 3 of my fuel injectors were broken. I still experience this issue and it is very scary not being able to accelerate on the highway with big semis and other vehicles coming behind me.

At 7473 miles, reduced engine power light came on while driving the car. Diagnostic code: P0013. Car was towed 50 miles to a dealer for repair and replacement of exhaust camshaft position actuator. Car was driven 4 times before the reduced engine power light came on again. Mileage under 8000. Diagnostic code: P0013. In both cases, the car still ran but it misses and cuts out.
