What 687 owners told NHTSA about the 2017 Chevrolet Malibu Eco

The vehicle constantly reduces speed when there are no issues with weather or any other issues on the road. This issues can potentially be fatal. I have had it checked and the diagnostic machine says it’s sensor issue that was reported for recall but my car was not part of the said recall. The car completely shuts off and will turn on by itself after 10 minutes. Uncertain what to do

On January 2022, Wednesday the 19th. My husband, myself and our two daughters 12 & 4 are on the Northbound freeway 99 in the far-right lane and the car pops up with the warning “Engine Power Reduce” and then proceeded to decline in speed from 70 MPH to 15 Mph almost instantly almost causing an accident. WE all were so shaken up! Had we been in front of a big rig we would have been crush from the backseat as fast as the speed declined. WE just bought this vehicle 5 months ago no more than 10K miles on it. The dealership says its not there problem to contact GM. Nobody will help this is a death trap vehicle. There are already multiple class action lawsuits about this issue and the vehicle. We are simply being told to buy a newer vehicle rather then someone taking ownership of this issue. This is a deadly issue and why there is not a recall is outrageous, There are cars out there that are capable of causing a deadly crash and killing thousands of people and everyone is turning there head when the consumers are reaching out for help.

An error message appears on the dash, ENGINE POWER REDUCED. It happen three times this morning and twice yesterday - probably a dozen times over the past year. I've had it into the dealer but they could not find anything by the time I got there. It has happened at 35 MPH and between 45-55 MPH, suddenly and with no other warnings. Turning off the engine for a few minutes clears the message on the dah, but the check engine light remains lit. The check engine light will clear eventually - it may be a few hours or two days of driving. Again, I've had it checked on multiple occasions as the car was "certified" by GM, but now the warranty has expired, the issue continues and I see a LOT of reports of the same online.

Car voltage stays very high (between 14.8 and 15 volts) for extended periods of time. At which point the windows have fogged up and there is a raw egg smell in the cabin - probably Sulfur. Both the hybrid and the 12v car battery are located in the truck and there are vents that draw air from the cabin to ventilate those batteries. The car voltage will also stay at 12.5 to 12.6 for extended periods of time. During both high and low periods numerous internal systems have failed, including bit not limited to steering assist, anti-locks bakes, Stabilitrack, On star, Hybrid Control Processor and ECM. Car has been brought to the dealer 3 times. First time (early November 2021) it was diagnosed with an hybrid inverter and a software update was installed. Issues continued. As of 12/28/21, Coggin Chevrolet (Jacksonville, FL) has had the car for 2 weeks and can't fix or confirm what is wrong with the car. I have received numerous e-mails from On-star with engine error codes as well as 5 messages saying there is an issue with the Electric Drive Unit in the car. The car has roughly 24K miles on it.

Driving on highway at about 65 mph on family trip to Delaware. . Car suddenly gave reduced acceleration error and speed started declining while in traffic. No warning.checked chevron app on phone and it did not see anything wrong. There was NO check engine or anything. Got to a dealer and they said it was probably a sensor for gas pedal. 5 days later driving home to Georgia from trip on highway around same rate of speed. No warning . The check engine light and reduced engine power warning message came on. This time the Chevrolet app notified me of trouble and said I needed the car seen within a day. .Got to a dealer and now they say they think it may be the cam shaft based on the code but they cannot replicate issue. I took a photo of the alert from the second incident . Car has about 46,000 miles and is well maintained . Our safety was at risk both times but especially the first time as we were in traffic and speed declined .

Was driving to work at 5:00 am today and merged onto a busy highway. After accelerating to 60 mph, there was a message that appear on my dashboard that read engine power reduced. It was not safe traveling at the speed that I was. The check engine light came on as well as the Stability Control symbol and my car reduced its speed and would not accelerate back to a safe speed. I am going to take it to the dealership and try to get the problem diagnosed. I really hope this issue gets resolved.

Intermittent shifts, no reverse, MIL illuminated Happened in rush hour traffic, could not move out of EMS workers way because of reverse failure. Nearly ran into vehicle in front of me due to such harsh sift from 1st gear to 2nd gear. Currently being inspected by local Chevrolet dealer. No warning light when incident occurred, only came on when I was able to turn the car off and back on. Extremely dangerous circumstance that could have easily been prevented had GM issued a recall on Service Bulletin 18-NA-081.

STEERING ASSIST REDUCED DRIVE WITH CARE message comes on car screen. The steering wheel jerks and acceleration is reduced. This is putting everyone in my car at risk as we are not able to accelerate fast enough if anything were to happen. Car has been taken to the dealership and they are unable to identify the problem. I checked online and multiple Malibus are having this problem. If you're looking for a safe car for your family member this is not the car. These cars have these errors built in the system and the dealership are unable to find the problem costing a lot of money on diagnostics to get no results. Please notice all the complaints I hope my word is heard. If mine is not heard I hope the next persons will be.

This class action lawsuit was filed in the U.S. District Court for the Eastern District of Michigan by three separate plaintiffs in Wisconsin, Minnesota and Maryland, Car Complaints reports. The suit alleges certain GM vehicles fail to detect when the gear selector has been shifted into Park, blocking the ability for the user to shut the vehicle off. Typically a ‘Shift to Park’ warning message will appear on the driver information center when this happens. The user can jiggle and or move the gear shifter in order to remedy the issue, although this technique does not always work. GM dealer witnessed the problem. MY REPAIR COST AT A GM DEALER WAS $391.11.
