2017 Chevrolet Malibu

The warning light comes on and off and is showing (P0498/P0449) which is the evaporative emission system vent control electrical circuit signal has low voltage for a predetermined period of time. Its calling to replace the evaporative emissions canister vent solenoid and I have seen 3 vehicles the same as mine needed the same thing fixed. When the vehicle is in park you can feel it jerk and also while pressing gas when you pull off it stalls. When cranking you can smell fumes .

On numerous occasions while driving on highway my dashboard will display reduced engine power and engine light comes on. My traction control light also comes on. Car loses power quickly and will not accelerate. I’ve had to pull over numerous times almost being hit by cars behind me. Took it to get repaired and had to have fuel pump replaced as wires had melted to side of pump. Three months later same problem happened. This car is scary to drive

In February 2023, we took the Malibu into the dealership for reduced engine power dashboard notification. Light went off when in shop, got the car back and light on once again. When at a red light that turned green, accelerated but car would not go over 20 MPH. Almost rear ended. Dealership replaced the vacuum pump gasket and seal. Fast forward one year later. Once again, reduced engine power notification came on again. Once again at red light, when light turned green, car wouldn't accelerate and was very close to being rear ended and difficult to make it through the intersection. Currently at dealer (1/18/24) with dealer having no idea what is wrong with car (today is 1/24/24). The dealer today stated it will be another 1-2 weeks. That will make it three weeks for a diagnoisis. With reduced engine power, it is very dangerous to drive a vehicle like this. Of course, there are hundreds of other complaints for this issue/make/model.

bought this kind of new and while still under warranty reduced power engine light came on & engine is reduced to 20 mph have to pull over shut it off wait a few minutes and start it back up and then it will be all right for a while we called dealer made an appointment but by the time the appointment came around the light had gone out they said the light needs to be on in order for them to diagnose the problem the light goes off after about 50 miles after this happens so we could never get it into them within that 50 mile time frame we gave up after a while now it's happening more often and I hear that maybe a class action suit coming they don't seem to be able to solve the problem. we still own this 2017 Chevy Malibu and it is still doing it today.

So basically when I'm driving it automatically I don't know where says engine power reduce which cuts the power down when you're on the highway and see if you're doing 70 miles per hour and all of a sudden that light comes on your check engine light comes on and it reduces the strength of the vehicle so ithe vehicle so we can cause multiple accidents

My 2017 Malibu suddenly had the "check engine" light come on, and a message indicating that a "reduced power mode" had been initiated. I drove the car immediately to the local dealer, who said I needed an appointment to have it checked. I checked the OBD2 codes with my personal meter, which showed a p2138 code, indicating a problem with a throttle body sensor. When I started my car the next morning the MIL light didn't come on. At the dealer I was told they couldn't do anything with the car because the light wasn't on. I pointed out that the failure codes were stored in the ECM, but they said diagnosis wasn't possible with the light off. The service writer indicated the problem was not uncommon on GM cars and that even his wife's car had similar problems. When this occurred I was fortunate to be on a local suburban road where reduced speed was not that great of a problem. Much of the time I am on freeways in several major Midwestern cities where aggressive drivers are packed together. I read a number of complaints on the NHTSA site indicating same complaints from Malibu owners. A sudden reduction of speed in a congested area is a recipe for disaster. The service writer even stated that GM had an extended warranty on the pedal assembly and TPI sensors. But he refused to try and diagnose the issue, unless I brought the car in immediately if and when the MIL light was illuminated, even if I was 500 miles away. As this intermittent behavior is a known and common issue I feel that GM should be compelled to do something to correct these defects before a truly dangerous incident occurs, causing devastating results. But I'm sure that this will go on until misfortune causes those in power to ask. Why didn't somebody do something?
