What 786 owners told NHTSA about the 2016 Chevrolet Impala Eco Eassist

I was driving about 70mph on a highway trying to pass a semi-truck. As I signaled right blinker to merge back into the right lane, the speed reduced to 40mph without notice. I then seen a notification on the dashboard saying "Engine Power Reduced". The car would not accelerate fast enough to clear the truck therefore almost causing a collision of 2 semi-trucks and myself. I was forced to drive off road to help avoid the collision. My fiancé was in the passenger seat when this happened on 11/25/2023. He then began telling me this happened to him a few months prior but he didn't mention it because it resolved itself. This was actually the 3rd time it had happened in this car over the last 2 years. I spoke to the chevy dealership about it the first time I experienced this and they advised that it had not been made a safety recall at that time yet, but the technician who helped me said his son experienced the same thing and it was becoming quite common. It still has not been recalled but there is currently a class action lawsuit because of this. I feel this is very dangerous and what I considered to be reliable transportation, is no longer the case for my family after this experience. This needs to be recalled immediately before people lose lives. Especially since the parts were Manufactured incorrectly and Chevrolet had knowledge prior to releasing 2016-2018 vehicles.

I was driving in the high way using cruise control then my car just randomly slowed down on the highway, my stabilitrack sign came on and my check engine sign started to blink and my engine started to shake my car.

My 2016 Malibu is a piece of shit. Randomly, and this cannot be anticipated or reproduced, I will be driving and the car will say "engine power has been reduced". This is dangerous! It takes me from 70 mph on the highway to 15 mph almost immediately. I cannot speed up. It has almost caused at lease 5 accidents. It happens on the freeway, regular roads etc. and Chevrolet refuses to issue a recall to fix it. I can't take it into a dealership because it cannot be reduced and Chevrolet was EXTREMELY rude. They said you issue recalls and I need to contact you. The most recent date this happened was 9/25/2023 but it has happened many other times.

The engine only has 78K miles on it. I took it in because I received a notification that said stabilitrack. First I had a mechanic change the spark plugs, then I was told I had to take it in for a bigger issue with the engine. I was told it would cost $2500 just to break down the engine and diagnose it. Then I was quoted 11k on top of that to completely replace the engine. 78k miles and the engine needs replacing for more then the car is worth. The diagnosis was that I had a piston crack and the whole engine was ruined.

I was driving down the interstate when all of a sudden my information center on my was driving down the interstate when all of a sudden my information center on my 2016 Chevy Malibu popped up a warning, reduced engine power and drop me down to 20 mph without warning. I barely made it to the side of the road before being run over by 18 wheelers all around me. Once I got it home I read the code, and it shows there’s not enough power going to the turbo in the engine that’s caused by the accelerator sensor. When I start at low speed or from a stop in attempt to accelerate the car hesitates to the point I can’t pull out with any cars around because I will be hit. I’ve been told this is a known problem for the vehicle and it’s a $500 part to fix. It’s extremely dangerous and I am so shocked there has not been a recall for this, it is putting everybody that is in one of these vehicles in danger

I just bought this car 2 weeks ago. Had to replace the windshield wiper pump. There are at least 10 TSBs on the vehicle I'm on disability I can't afford to fix all that. The rear hub bearing was barely making noise when I bought it. Now tire feels like it's going to fall off. I believe there's a TSB on when you put the car in park and shut it off then it's not going in to gear even though it said it's into gear so I have to get that fixed as well. Can't Chevy fix thermostats just like I have to fix my mistakes in life.
