Took my car for an oil change 4/17/2026 dealership stated I had a recall on the 21 chevy malibu for Fuel injection module, They could not do the recall repair because they did not have the part. So the lady called me. 4/21/2026 to make appointment for recall for 4/23/2026. But later that day on 4/21 my engine light came out and my car started having problems. When ran a diagnostic it gave a code for the fuel injection

I was driving and car suddenly reduced speed,engine light came on and message came across dash “engine power reduced” and a text was sent to tell me I have a transmission issue. Now car won’t drive past 25-30mph dealership indicated this is a faulty gas pedal which cost over $600 to repair. Did my research and this is apparently a “known” problem common in 2016-2022. Vehicles but is not an official recall. Also dealership said only “certain” vin numbers with this problem are covered. I have a 2021 and I am not one of them. Not fair. It’s a known problem it should be fixed.

The engine light was on and had my vehicle was stalling while driving in traffic. The service code P1101 was on and had my vehicle fixed. The light stayed off for few months then same service code is back on. I've read that there was a recall for 2019 models with same issue. My vehicle is a 2021 Chevrolet Malibu LT and has same engine as the 2019 models.

I was driving on the highway and the check engine light came on. The car slowed down due to lack of power. I got off at the nearest exit and the car stalled. I tried to start it but it kept clicking rapidly. The car died at a dangerous intersection so I put my hazard lights on and called 911. The police arrived and asked me to put the car in neutral, but it wouldn't shift. The officer was able to start the car, and I drove it to a mechanic. He ran a diagnostic and the fault code is P023F, Fuel Pump Secondary Circuit/Open. There are no open recalls on the vehicle, but this is a major safety issue. If I hadn't been able to get off the highway it could have caused a major accident. Also, when I put the car in park and turn it off, the dashboard tells me Shift To Park even though the car is already in park.

Hello , in January 18,2024 I’ve purchased a 2021 Chevrolet Malibu from Toyota of Dallas on Forest Lane. Within the first 24 hours I got a flat due to a bad tire , but was informed they did a full inspection before giving me the car . I contacted my sales representative she informed me to to bring the vehicle up there once they were open to see if they could resolved the issue due to me paying for a new tire. Once arrived they stated they could not compensate because I bought a tire somewhere else . Within 48 days of having the vehicle , I contacted them sale representative which I still have messages the my vehicle is saying “shift to park” while in park . They stated that it could just be a “sensor” used to bring it . Once I brought it in the car was not doing it & they informed me theirs nothing they can do unless the car does it again when I bring it . The car ends up doing it again I contact them my sale person no longer work there so I disclose this issue with another sales person , which no one documented but I have the messages to prove I informed them. I brought the car up there again & one of the technicians informed me “ just push your gear shift forward a little & it will just turn off”. So I did so & it worked but not for long . My car kept continuously doing it afterwards & they suggested to bring it in for diagnostic , however they way my schedule is at the probation office I work Monday - Friday & that is my only transportation to work or my schedule would not align . So on December 3,2024 my check engine light comes on in the vehicle while driving home . I immediately took my car to the Auto Zone on Buckner which I also have the paperwork for their diagnostic suggest cleaning the throttle bottle & also code P1101. I notice on the paper it stated my car would not pass a inspection with those code & said transmission status - red . I immediately set me appointment for 12/04/24 to take my car to the dealership. I took my car there they stated I arrived

My 2021 Chevy Malibu's transmission is shredding. The car does not go into D right away, it acts like the engine is completely disengaged. If I go from R to D several times, the engine sometimes revs very high when I step on the gas and then lurches the car forward a few feet. Sometimes, when I try to get the car into first gear, the car will completely shut down with the vehicle in D, and I have to put it in P and restart it. Other times, I can put it in different gears a few times until R engages very sharply (the whole vehicle moves), and then it will engage into D just as sharp. My check engine light will come on and go off, although it never did before this problem started, and whenever it comes on, the car will stop working whenever I stop the vehicle and try to go again (i.e. red lights). I only have one car and am forced to continue to drive this vehicle while I wait on repairs. I have two kids and I am terrified that my transmission is going to completely give out while we're driving, or the engine is going to start shutting down while the vehicle is in motion! The dealership told me that two other Malibus were in with the same exact issue within days of each other. A GM inspector confirmed the transmission is shredding. My friend had a Chevy Impala that did the exact same thing
