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?

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.

Reduced engine power message pops up when I-??m driving at 45 or lower speed. First time this happened was about 4 months ago, and couldn-??t drive faster than 30 mph. After starting my vehicle a couple of times the message goes away. This reduced engine power message is almost a daily thing, but now it doesn-??t affect my speed anymore, I can go at 65 mph and even with that warning light on.

While driving th vehicle the component that ruptured was the vehicles vacuum brake booster pump which connected directly to the engine. The ruptured caused shards of metal to be launched into the engine resulting in no brake power and needs an engine swap. There was a recall on this model vehicle for the Pedal sensor malfunction that results in the cars engine going into a reduced power mode abruptly and suddenly while driving. This malfunction has occurred on this vehicle and I was not aware of this vehicle models recall history but it stated that the recall was successfully closed out in 2020. I purchased my 2018 Chevy Malibu in the year 2021 and the issue still persist. I am not confident that the recall on this vehicle was either fully completed or successfully fixed before purchasing. The car is now at the dealer and the repair team explains the vehicle needs a new engine. I questioned about the pedal sensor malfunction and asked if it was possible that this malfunction sending the vehicle into a reduced power mode so suddenly could have effected or cause wear and tear on brake booster pump connected to the engine. The dealers repair team wasn-??t confident in saying it wasn-??t possible. This is likely a design issue and if a recall was completed and I was sold a vehicle uninformed of this potential issue but the malfunction still persisted I do not believe I should have to cover the full cost of repairs for this chain of events. This malfunctioned put me at danger and if it had occurred while my wife and 3 children were in the car it could have been life threatening not only to us but the other drivers around as well. With the engine reduced you can-??t accelerate and with the booster pump ruptures mid drive you lose all brake power. It is hard to understand the faulty design in this but I have read reviews that others have had the same issue so I do not believe I am alone in this.

Vehicle suddenly went into reduced engine power mode and nearly caused a crash. We pulled off to the side of the highway. Turned the car off and waited for about 5 minutes with our small children in the back seat. Restarted the car and check engine light remains on but the reduced engine power warning turned off. This just happened today and have not been to the dealership. Hoping Chevy recognizes this safety issue and issues a recall as many others have reported the same issue.

When putting my vehicle in park to turn off the car, a warning light comes on to put vehicle into park. The vehicle is already in park and am unable to turn off the vehicle. In order to turn off the engine I must repeatedly turn it on and off and hit the gear shifter multiple times. This problem is becoming more and more frequent. I see numerous other 2018 Malibus in the complaint section reporting the same issue. Come on Chevrolet fix this problem!

REDUCED POWER TO ENGINE. Previously had recall for this issue, which was replaced by Chevy service center. About a year later I had the same problem but had to pay out of pocket because there were no active recalls on the issue. As of today, I am receiving the same -??REDUCED POWER TO ENGINE-?? error and check engine light keeps coming on. This happens randomly but frequently almost every single day. Error will shut off after restarting car and then happens again not long after. I-??ve had this issue with multiple Chevy Malibus that I have owed and there is currently a class action lawsuit against GM for this exact issue.

Car hesitant to crank, once the Start/ stop button is pushed, the car will start, run smooth for a second or two then start to shake and putter like it-??s not getting fuel and loses it power and cuts off. I have to go through this process 5/6 times before the car will stay crunk. While driving Car will out the blue say reduced engine power and acts as if it does not want to pull or it is losing power! The car also has the eco saving feature where it cuts off at every stop and there is not an option be turned off and car is hesitant to start back up after it cuts off. Car is now starting to smoke from the tailpipe. The VVT intake and exhaust solienoids have oil getting into them and the PCV valve is about to crack open. The car throws codes like rich fuel intake, something to do with the catalytic system (in which I-??ve put a brand new catalytic converter on the car and it did not solve the issue) it also throws codes about a throttle and cam sensors and a few more codes.. I see where there are recalls for the (same make, model, year, and engine size) but my cars VIN is not included with the recall! Can we please get this as I need my car and need this issue fixed as soon as possible as it is dangerous for me and my 2 year to travel in this vehicle.

Driving normal. Upon application of brakes, brake pedal became stiff and brakes did not function normal. Had to apply immense pressure to stop and it sounded like brakes kept locking up. Vacuum pump that supplies vacuum for engine with turbo to function, along with the brake booster to be able to apply normal braking power, was destroyed. The inside of the vacuum pump is in pieces and part of the bushing that connects into the engine was broken. Caused by faulty vacuum pump, or faulty cam shaft. If this had happened while in traffic, it is likely a crash would have happened. Damage caused to the vacuum pump resulted in metal pieces in the engine block as well.

Since I got the car, if I let it go in auto stop, it has a hard time accelerating when I push the gas. It has gotten worse and now it has a hard time accelerating in general. When I push the gas it sounds really loud like it-??s struggling to go. I realized this is a safety issue for me and others when my car wasn-??t going at the light of a busy intersection, or when I-??m getting onto a highway and my car isn-??t picking up speed. This makes it scary for people already on the highway as Iam causing them to brake unexpectedly. Every time my check engine light comes on I take it to the dealership. It-??s been taken in for repairs multiple times but this issue still keeps coming back.

Saturday morning this is now the 3rd time it's been fixed and safe to drive. Once by the dealership in Baltimore Towson area. Check engine light came on I ran diagnostic I bought at the store to get the codes come to find out class actions for wrongful death because company knew about it. As I also see hundreds of he same complaints here. My wife on [XXX] Baltimore MD at the merge. She went from 60mph to 35mph. Then the car shut off with zero control of steering. Once in neutral she slightly touch the brakes which let it start up. Thank God no one was killed we have 2 beautiful 6 n 7 yr old girls what would I tell them. This needs addressed it happens after the batt needs changed I know 4 other owners 1 had just got one that's what triggered his same codes problems. Im I've Googled it but not one person solves it. It's gotta do w the start stop system INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
