2021 Chevrolet Malibu Electrical Problems

Your car is unexpectedly shifting into neutral while driving and displaying a message telling you to restart. When this happens, your steering wheel locks up and you can't accelerate, even though the car remains in drive. This occurred multiple times during a short drive home. The issue may be related to the neutral safety switch or transmission control system, which typically requires diagnostic testing at a dealership to pinpoint the exact cause.

While driving on the highway, a "SERVICE ESC" warning appeared on your dashboard, triggering engine power reduction that forced you to pull over abruptly. When this warning activates, your engine, transmission, and brakes don't function properly — the transmission won't shift gears, your gauges fluctuate wildly, GPS malfunctions, and your car may shut off completely. The brakes also don't engage as they should. Diagnosing this issue will likely require a full electrical system scan and possible replacement of the ESC (Electronic Stability Control) module or related sensors.

Your car sometimes won't recognize when the shift lever is in Park, which prevents the engine from fully shutting down and can drain your battery, leaving you stranded. This can also potentially cause transmission or electrical control issues. The manufacturer's solution is to replace the entire shifter assembly with an updated part.

Your 2021 Malibu's engine unexpectedly stalled while stopped at a red light in 2023, which you believe was caused by a defective fuel pump power control module covered under GM recall N252516900. As a result of this stalling issue, your vehicle now needs a new 12-volt battery, AC compressor, and serpentine belt — all replaced at significant cost and after 11 days without your car. You're requesting that GM cover both the recall repair and the cost of these related component failures, plus provide a loaner vehicle or rental reimbursement for the time your car was unavailable. The fix will involve replacing the fuel pump power control module as part of the recall, along with replacement of the battery, AC compressor, and drive belt.

After you shift into Park and turn off your car, a warning beep tells you to "place vehicle into park" even though it's already parked. You have to jiggle the gear shift several times to make the warning stop. This is concerning because you worry the car might not actually be in Park and could roll away.

I own a 2021 Chevy Malibu and I have been having issues with my transmission since November 5,2024. I was driving along at about 30 miles per hour When all of a sudden the car would not accelerate so I put the car in park and put the car back in drive and accelerated but only revved up but still would not move. I called a mechanic to look at my vehicle and he checked that I had transmission fluid and it was full. Upon further inspection he plugged an OBD code reader on my vehicle and came up with a P0700 Transmission Control System Malfunction which is the output shaft speed sensor or the vehicle speed sensor? I spoke to a shop about the problem and they said that that year and model car has a lot of complaints from owners. They said that it could cost up to 3,000 and up to replace the transmission. I think that it should be investigated for that issue?

I recently purchased this vehicle. Within the first week I was trapped in the vehicle sporadically. When I try to put my car into park, the car keep repeating "shift to park". I have tried to put the car through all gears, backing up and parking repeatedly to attempt to put the car back into park. I have been trapped in my car for hours trying to put it in gear. When I reached out to the dealership they stated that even though there is a recall for most Malibu's; however, my VIN number does not qualify for the recall.

When I turn off the car it displays a 'shift to park' message and the car tries to roll if I take my foot off of the brake. My [XXX] was beside the car and was almost run over. This is a problem that the car rolls away. I have to restart the car continuously and toggle the gear shift to get it to stop. It will not let the lights turn off and radio and/or the other components in the car and is running the battery down. There is a recall for this problem but it is VIN specific and my car is not included. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car is not registering that is in park. When I put the car in park the message on the dash will ding and say "shift to park" even though it is already in park.

The vehicle says shift to park. Even though the vehicle is in park. It then causes the vehicle power to remain on and kill the battery. I’ve seen multiple instances of this same problem on the same vehicle as mine and many other GM models. My warranty ran out in January (of course) and now the issue is occurring. I’ve been stranded with a dead battery 3 times already due to this. It’s literally a microswitch not functioning correctly to tell the computer that the vehicle is in park.

When trying to turn the car off, it will not allow me, warning light comes on saying shift to park. This has happened several times over the past week. I have to continuously turn the car on and off, put in drive then back to park before the message goes away, allowing me to turn off the car. I am 3k miles out of my bumper to bumper warranty, so the dealership is charging me $500.15 for a new shifter assembly for what they said was a common failure in GM cars. If its common then it should be a recall for several make and model years. My coworker has 2021 Blazer and the same thing happened to her but she was still under warranty so her repair cost $0.

When I move my car to park and shut off the vehicle it shows a "shift to park" message. This keeps my car from shutting off on a regular basis.

Malibu will be in park, engine off, but when exiting the vehicle a message will appear "SHIFT TO PARK", although the vehicle is in park. The electrical will not shut off, which is a hazard, as the vehicle's battery remains on. I am forced to turn the car on, shift to a different position (not "park", and then forcefully shift back to park). I contacted the dealer that has done all of my work, they were aware of the problem and offered to fix under warranty. They claim to have replaced my transmission harness. The problem was fixed for about one week, but now the problem has resumed sporadically. I have contacted the dealer again as of this morning to seek resolution. The consumer stated that the manufacturer has not resolved the issue yet.

3 times now, the car has turned off while in gear or in motion. In an Arbys drive thru on a hill above a highway. Backing out of a parking spot in VA. And pulling through a busy intersection in VA. The safety hazard is that you lose power brakes and steering when a vehicle isn’t running, one could easily be unable to avoid a wreck. Also the general danger of your vehicle randomly shutting off. No warning lights appear before during or after this happens. The 3 dealerships that have looked into the issue state they are unable to recreate the problems and there’s no codes stored in the system so there’s nothing they can do. No police or anybody other than the dealerships have inspected the vehicle. These issues began happening less than a week after purchasing the vehicle.

THIS WAS A RENTAL CAR, EQUIPPED WITH AN ELECTRONIC KEY FOB AND A STARTER/TURN ENGINE-OFF BUTTON ON THE DASHBOARD. THIS PARTICULAR VEHICLE COULD BE LOCKED REMOTELY FROM OUTSIDE THE VEHICLE, WHILE IT CONTINUED TO RUN. ADDITIONALLY, IT APPERED THAT AN OCCUPANT OF THE LOCKED VEHICLE WHO DID NOT HAVE AN ELECTRONIC KEYFOB IN HIS POSSESSION COULD NOT OPEN THE DOORS FROM THE INSIDE. THUS, ADULTS OR CHILDREN COULD BE ASPHYXIATED UNDER CERTAIN NOT-TOO-HARD-TO-IMAGINE SITUATIONS.
