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

When driving the car it will stop mid drive and slow to 20MPH. The car has broken down in the middle of the road on multiple occasions. It has locked me in the car where I am unable to get out. On one occasion the battery was dead and the car had locked me out. I had to have someone unlock it. The next day the car was fine with no signs of issues. The car has been taken to multiple mechanics and no one knows the issue. Car doesn’t throw any codes or show any symptoms of issues.

THIS HAS HAPPENED ON AN ALMOST DAILY BASIS SINCE 4/30/2024 stabilitrack warning on Ipc, security light, power steering goes out on freeway-while turning in an intersection-going 75 on the freeway while changing lanes, IPC displays ice warning when 90• outside, erratic shifting(being stuck in 2nd gear until it shifts to 4th), no start no crank condition ( I replaced the battery,had alternator tested, tested fuses, fuel pressure test, checked spark plugs and coil packs) key fob not unlocking doors or remote starting (battery was changed) passenger seat will only recline on one side, power mirrors erratically moving without user adjustment, Climate control sporadically disconnects (no lights in dash no power at all) I have not taken it to a dealership I can’t afford the outrageous prices. I have had my father (certified ford technician) inspect the car. This car has become unsafe for me to drive with my children and I am terrified that it’s going to cause us to wreck and cause serious injury or death

My car was started shaking really bad and the stabili trak sensor came on. My engine had to be replaced in February 2023. My car was at 66K miles. I rarely drove it. I worked from home for 3 years due to the pandemic. I purchased the car with about 12K miles. I was on my way home and my car just shut off. I could not get it to start at all. The stabili trak light came on. This was in January 2024 with 75K miles. The tow truck driver told me he had picked up multiple Chevrolets experiencing this same issue. It took the dealership almost two months to figure out that the crank sensor needed to be replaced.

When the auto shutdown feature on the car turns off the engine at a stop light; stop sign; or other reason, sometimes the cars entire electrical system shuts down. This happened twice to me. Once at a stoplight and once when freeway traffic came to a sudden stop. You cannot open the electrical trunk to get hazard lights or jumper cables; cannot get the car out of gear or out of park to move it safely out of traffic; cannot turn car hazard lights on; or even unlock a door that is locked. On freeway incident, I was in the middle of 3 lanes and traffic quickly got back up to ~60 mph. Fortunately, I was able to get out of the car and a few hundred feet away in case someone hit my car. This happened during the day and I cannot imagine how someone would see a stalled vehicle in the middle of the freeway in the dark with enough time to stop. My battery was brand new and in perfect order. The dealership said it is a known issue and they no longer sell cars with this auto shutoff feature.

Vehicle engine light reported codes P050F, FE8:engine, and FE9. It was determined the Brake Booster Vacuum Pump was leaking oil and was faulty. It has been replaced and brakes better. Engine light went off. The other diagnostic by my mechanic showed the Oil Control Intake and Exhaust Variable Valve Timing (VVT) Solenoid needed to be replaced too.

I am very upset right because I purchased this Chevy Malibu 2016 from Vroom. It was fine at first and then things start to go downhill. For starters my tire light came on first only a week after having the car, then the shift into was appearing on the dashboard as well as the engine light. Then my husband spent almost 2000 on the brakes because the car was making this horrible sound and I almost couldn't stop the car because the pedal was stuck and would not push down. Thank God no one was hurt. Then my car just shut off twice one day at a busy intersection, it went completely dead with my children in the car. This is a ongoing issue. Now I had a diagnostic test ran on my vehicle and it was said I needed a new motor only after having the car for only a year. This car is very dangerous and I wish they would take it off the market, because it will also reduce your speed while driving out of nowhere. Chevrolet should be responsible for all problems before they are aware of these issues!

Occasionally when the car is put in park, it does not alert the rest of the car that it's in park. Although I turn the car off, it beeps like it's still on an I have to turn the car on again and move it back into park in order for it to stop. There has been a recall for this issue but so far, my car has not shown up and for that reason, the dealer/mechanic will not repair it which is understandable on their part. Please advise. Thank you.

Car moves even in park due to faulty gear shifter. It’s made of plastic. Computer reads error message “shift to park” and still moves while in park. A danger to other cars and car battery.

While driving at a fast pace a hazard message pops up on dash that states engine power reduced and the car goes slow unable to accelerate past 20 mph. It doesn’t happen all the time but it’s been happening quite frequently and it’s dangerous. I’m assuming there has something to do with the speed and or fuel function. The vehicle has not been inspected. I am willing to bring it for inspection if needed. I feel like this is a malfunction and I’m requesting this to be fixed.

Warning display on dash reads "Engine power is reduced " and forces and abrupt reduction on vehicle speed, Especially on highway driving on commute. Noticed online multiple similar concerns and complaints. No recall or extended warranty?

*Accelerator Pedal Position Sensor- It is available upon request. * Due to the malfunction of the accelerator Pedal Position Sensor, the check engine light comes on and it flashes "engine reduced power" which slows the car down to a very low rate of speed not allowing the driver to go any faster. I was on the highway going speeds of around 75mph and that light came on and slowed my vehicle down which caused the car behind me to almost run into the back of my vehicle. I've had this occurrence with this problem several times. * UNKNOWN *UNKNOWN *No, absolutely nothing prior to the check engine light and "engine reduced power". The issue is sporadic and happens at any given moment. There is no warning that alerts when this happens.

My car enters a reduced engine power mode causing my car to slow down during high speeds with a potential acciden…. the Malfunction Indicator Light (Check Engine Light) will illuminate, the ‘Engine Power is Reduced’ message will display. I have called GM and was told it wouldn't be covered, I have talked to the dealer and taken it in before but I can't afford to keep paying a $150 fee to have my car looked at. I have been having this issue since April
