I was going about 75 mph on the express way with one lane open due to construction. My car started losing power. I heard the chime and upon the dashboard were the words power reduced. My car slowed down in a matter of seconds to around 45 mph. A 18 wheeler was trailing behind me. I quickly jumped in the emergency lane to my right and took the next exit while riding the emergency lane. I shut the car off at the gas station, sat there for about 10 minutes, restarting my car helped temporarily. I was 3 hours away from home and had to drive back unknowingly if I will make it or not. I reached out to Chevrolet and was told to bring it in and leave it but they had no loaner cars for anyone at that time. I have replaced 2 sensors and now my start /stop has quit working. I spoke with 5 visitors at Chevrolet and we all were having the same issues. This is something ongoing according to my research on this particular vehicle and should be recalled ASAP.

Vehicle was being driven at 60 mph on the highway when the brakes weren't responding as I was entering a sharp curve. Had to stand on the brakes and manually lower the gears to keep from hitting a tree head-on. Check engine light was on. P0014, p0017, and p0556 codes were pulled before having it towed to the first mechanic. Car wouldn't start after it was parked after the initial incident. The first mechanic was unable to diagnose so the vehicle was towed to the Chevrolet dealership. They say the brake vacuum pump malfunctioned and caused permanent damage to the engine rendering the car inoperable and I will have to have a new engine installed. The car drove fine prior to the vacuum pump failure.

My vehicle has been having issues for the past 2-3 years with its engine acceleration, the bcm and ecm are faulty and or my fuses continue to fail, my check engine comes on with a service esc, power steering depleted, shift to park, and a service security system warning.

- reduced engine power, appears on the dashboard. The motor begins to shake, slow down excessively if I'm driving on the highway, and needs to be shut off to reset the computer. Yes, this is available for inspection. However, we are going to try to fix this ASAP, as I drive an hour to and from work each day, this isn't safe, I'm stressed out as soon as I think about driving, and I am worried I'll get stranded on the side of the road. . This puts me and others at risk, because I can be going 70 mph and the alarm goes off and I instantly slow down from 70 to about 30 mph, I need to immediately get to the side of the road, or I might not be able to move out of the way of traffic. I am unable to use the accelerator at this time if I needed to get to a more safe location. This can happen zero times, to 5 times, per my morning drives to work. I need to pull over, put my flashers on, turn off my car, and hope that it resets right away and I can continue my drive. Other times, I need to let it sit at least 5 minutes before the reduced engine power warning goes off. - there were no warnings. It first happened just putting the vehicle into reverse in our driveway. Now it happens when I am driving. We just bought this vehicle used from the gm dealership with no warranty. It is a 2011 Malibu with only 90,000 miles on it. This can happen going from park to reverse, to going highway speeds.

The clutch solenoid started failing without warning or notice. This was finally confirmed by a transmission shop after a warning lamp related to the issue finally popped up after months of issues. My safety was put at risk due to the sudden and intermittent failure to shift into drive. This would sometimes lead to the engine stuttering then shutting off while still in drive. Attempts for dealers and private shops to nail down the issue were unsuccessful due to the system not reporting or recording any information related to this failure to shift. Again the danger came intermittently and suddenly when, shifting from park to drive, shifting from park - reverse - then drive. It would cause my vehicle to “stall out” in an active lane of traffic. This issue occurs from probably 60,000 - 90,000 miles when the system finally threw p0700 and p2714 codes to point to the issue.

Reduced engine power that causes vehicle to lose power at dangerously low speeds.

So I found a recall on a twenty twenty two Malibu l t one point five liter turbo, which is exactly what I have, and the recall describes my exact issue to the t. It spits out a code for a bad fuel pump. G d I fuel pump, and a couple other codes that are secondary like the camshaft sensor fuel bank 1, solenoids, which both I had replaced this week? the car barely has a 100000 miles, and despite the reduced engine power message coming on, like I said every symptom, my car showing is lining up with the recall yet, gm says my VIN isn't one that's covered out of the 22 Malibu 1. 5 onliters and the fix is 30 recalibration of ecm. This is not a new issue to g. M. The older models had a similar issue and like I said, the specific 22 model that I have has a recall and tons of people have had issues. The car won't go over forty I get maybe seven or eight miles to the gallon, no power hardly, speeds on the freeway immediately dropped to dangerous speeds nearly causing wreck. How can they say the same identical engine and yr,make,model isnt covered while there's lawsuits abs tons of people with same issue. Through two mechanics, I've ruled out the other two code issues by like I said replacing solenoids and camshaft position sensor. Please help I'm still paying a good amount of money on a lien. For this, vehicle can't afford eleven hundred dollars for them to replace a fuel pump that truly isn't bad abs only vehicle with daughter who's in wheelchair needs safe reliable car.

When I was on auto stop, my car never started back up. The steering wheel and brakes were frozen, and I could barely pull off the road I was on. Turning the key did not help, as the engine wouldn't turn back on.

Happened around 46000 miles after receiving a recall notice in the mail about the pedal positioning sensor causing a reduced engine power signal, and immediately reducing speeds on the interstate. Local chevy dealership replaced. Fast-forward 80k miles and the same incident is happening, however likely not going to be covered by gm. Same message, same code being detected.

Fuel leaking from engine.

The car consistently says shift to park even after being placed in the park position. The car won't cut off. This has been an ongoing issue for around 1 month. I read online that this is common in chevy. There should be a recall.

Car showing warning : engine power reduced car decelerate unexpectedly car won’t accelerate past 20 mph intermittently - when putting car in park, car won’t recognize when in the park positioned and shows warning : shift to park.

We have had multiple codes with loss of power.

Engine power reduced light keeps coming on while driving and the car stalls and won't go over 20mph. Several repairs later and it is still happening almost daily. It has nearly caused an accident several times. This needs to be fixed and a recall for the issue needs to be issued by chevy. With this many people experiencing this problem, why isn't chevy obligated to address the issue?.

When driving down a major highway going 70mph, my 2017 chevy Malibu speeds decreased, the brakes locked up, and the vehicle would not accelerate. Eventually the car came to a complete stop and an “engine power reduced” notification came up on the dash. I was able to pull off to the side of the road but I was traveling at a high rate of speed on a busy road, I almost got hit multiple times by people behind me who also had to swerve out of the way to keep from getting hit. After turning the car off and on again it seemed to run fine for a few months until the issue happened again going down a busy highway (65mph) again putting myself, my kids and others on the road behind me at risk. Now the car won’t move more than 5 feet before shutting off with “ engine power reduced “ still displaying on the screen.

The contact owns a 2018 Chevrolet Malibu. The contact stated that while on a trip and traveling at high altitudes, the check engine warning light was displayed on the instrument panel. The contact used a code reader which showed that the barometric pressure sensor was defective. Once the contact returned home, the mass air flow sensor was replaced. The following year while traveling in the same region at high altitude levels, the failure recurred. The contact also stated that the engine booster had started to fail due to ice accumulation in the charge air cooler (cac), which restricted airflow. As a result of the failure, the vehicle failed to accelerate above 25 mph. Upon investigation, the contact discovered technical service bulletin 18-na-069; which the contact linked to the failure. The dealer was notified of the failure, but the contact was informed that the vehicle was out of warranty. The manufacturer was also notified of the failure and referred the contact back to the dealer for assistance. The vehicle was not repaired. The failure mileage was approximately 76,000.

I repeatedly get a “reduced power to engine” alert on my dash which causes my car to decelerate and I lose my power steering. This last time, the alert popped up on my dash, my car decelerated, and then my brakes would not work. I could not push the brake down to stop my car and ended up in a ditch. My brakes are now hard and I cannot start my car because of it. I have already had the recall for this issue fixed in the past but this will be the 3rd time I have brought my vehicle in for the same problem. I had diagnostic codes ran on my car soon after the accident happened and have attached the pictures to this form.

In December 2024, driving to work when car abruptly stopped (no power). Waited for a while for my husband to arrive.

I will be driving at posted speed limits (typically 55 to 60 mph) and while going up a hill, the engine loses power. I get a notice on my screen that states engine power reduced. Speed reduces to no more than 35 mph. This can put others in danger if they are too close or if the roads are icy due to it being winter in indiana. I put on my hazard lights, and I am able to pull off the side of the road, turn off the car for 5 minutes and restart it and have power back. But engine light remains on. Mechanics cannot find anything wrong. No warnings prior to the incident. In fact, the car loses power and then the message appears on screen. This has happened 7 times in the last 4 months.

Powertrain there is a problem with auto stop restarting then dying. The transmission not engaging after a complete stop like it is neutral this only happens after the car has been driven a bit everything at temp. Today stopped for trash service auto stop engaged got ready to go nothing gunning and gunning never died like no power though finally moved no more stops till home a problem sitting in road can not move. Have not taken to shop yet money for it now not.

P0420 code.

Took my car to chevy dealership to diagnose my car, as it was rough idling, causing hesitation, and knocking. . . All while the check engine light was on. They showed me two codes my car was giving from the check engine light. They said he would look further into it. They told me I needed a tune up, though I had gotten a tune up 4 months prior. They fixed some things and charged me over $4,000. The day I drove off the lot, the problems were still present. On my way home going about 50 mph, my car slowed down and the engine reduced power illuminated. I kept driving because I needed a car for work. The car continued to decline and acted like it didn't want to accelerate when pressing the gas. I finally took it back into chevy, and they told me it was my pistons. I'm 90% sure there is a defect that they won't tell me about, or the won't fix. I've had the car 2 years. Now the car won't run.

I am filing a complaint regarding a 2014 Chevrolet Malibu that I purchased from a dealership on November 22, 2024. The vehicle was advertised as being in “excellent condition” at the dealership’s site. During the test drive, I raised concerns about potential transmission issues, but the dealership assured me that the vehicle was “clean” and safe to drive. Unfortunately, this assurance turned out to be false, as the vehicle has since displayed significant mechanical failures, including overheating issues, that pose serious safety risks. Within a week of purchase, the vehicle broke down twice: first on November 29, while driving to work, and again on November 30, while on I-10 katy freeway. The second breakdown created a life-threatening situation as the vehicle suddenly lost power in traffic. I incurred towing costs of $125 to return the vehicle to the dealership. After an attempted repair, the vehicle was returned to me on December 5, 2024. However, it broke down again on December 8, 2024, requiring another tow. Since that time, the vehicle has remained at the dealership, yet no adequate resolution has been provided. Additionally, I have since discovered that the vehicle has persistent overheating issues that were not disclosed at the time of sale. These overheating problems pose a serious safety risk as they could result in a fire or explosion, endangering my life and the lives of others on the road. The dealership’s negligence in addressing these critical safety concerns demonstrates a disregard for consumer safety. I believe the dealership knowingly sold me a defective vehicle with significant mechanical issues that were either hidden or misrepresented. The sudden and repeated breakdowns, particularly in hazardous driving conditions, and the risk of fire or explosion due to overheating, warrant immediate attention from the NHTSA.
