2019 Chevrolet Malibu

My 2019 Chevrolet Malibu has severe safety defects involving the engine, powertrain, and speed control. The vehicle will sometimes accelerate on its own with my foot off the gas, and other times it loses all power while pulling into traffic. This creates an immediate risk of a crash. Multiple diagnostic codes appear repeatedly, including P0299 (turbo underboost), P0101 (mass air flow performance), P1101 (intake airflow performance), and P0506 (idle control RPM too low). The charge-air hose repeatedly blows off the throttle body while driving, causing sudden loss of power. The vehicle was sold to me by a dealer as safe and reliable, but these defects appeared shortly after purchase. The unintended acceleration and sudden loss of power make the car dangerous to drive. This appears to be a serious mechanical and safety-related defect that could cause an accident.

I was traveling down i-25 at 75 mph because that is what the speed limit here in Colorado. I was traveling south heading to Colorado Springs to visit family and i was entering near Castle Rock and my vechile would not go at all forward and it seemed as if I lost power to acceleration and I believe it was 2 or 3 lanes to exit off an off ramp as cars pasted me by honking their horns it was very scary as I pulled over to the side of the road letting it glide or coast to a stop very slowly I finally came to a stop.. as I have been reading some recalls due too a transmission issues for these types of vechiles I really hope I'm going about it right and someone reaches out to me about what it is that might be going on because even though my car does not have it listed by a Vin number I still believe that my 2019 Chevy Malibu has been subject to recalls for issues including a faulty rear seat belt retractor and a transmission problem that could lead to a loss of propulsion. The rear seat belt recall involves improperly secured retractors, and the transmission recall is due to a start-stop accumulator endcap with missing bolts, which could cause a leak and a loss of propulsion or a fire risk. And would like to have this addressed and or hits the right people concerning this not only for myself but safety for other people traveling at high speeds like myself that night... I was 5 days past my dealership warranty when I purchased the vechile from them and made it 6 days because I could get ahold of anyone on the 5 day when this incident occurred and then I called GM because I believe it would of fell under a drive train warranty but they said which was only 5 years warranty on this vechile from the day it was purchased its first time my vechile only has 82000 miles on it and I got it from a dealership here in Colorado with 64 or 62000 miles and since then I'm paying on a vechile that is no longer in service parked Sincerely and hopefully this reaches the right person...

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.
