Vehicle Speed Control Problems of Chevrolet Malibu - part 2

The power brake vacuum assist failure nearly caused a wreck. The part failed while we were driving on 45 north going 65 miles per hour on a busy highway. As the breaks gave out the engine light said “reduced power”. Moments later, the breaks stopped working and the engine stopped running. We were able to coast off the highway and into an heb parking lot and have the vehicle towed. The mechanic took the part off and found that it was in pieces causing further examination of the engine to look for the missing metal. Pictures are available to see the damage. Even after completing the repairs the vehicle is showing reduced power. We are still trying to get it fixed but understand that the Chevrolet company is aware of the issue but never issued a recall.

On Jan 22,2024 while driving on the interstate the speed was unexpectedly instantly reduced, the car would not accelerate over 60 mph and the service engine light came on, the car was safely driven off the highway then towed to the dealership. My safety as well as the safety of other drivers on the highway was at risk when the car suddenly decreased to 60 mph from 75 mph which could have caused a collision. The inspection at the dealership confirmed that the issue was the intercooler for turbo found moisture/oil frozen in charge air cooler causing restriction in induction system, and the part design has been updated to help prevent the issue from happening again. My issue is that if the part has been updated that means that gm is aware of the issue and should be responsible for the cost of the part or there should have been a recall on the part. The consumer should not have to be responsible for the cost of the part or the repair to the vehicle. It is unknown if the part was inspected by an insurance representative but it was inspected by the dealership where the car was purchased. There were no prior warnings, lights or lamps occurring before the date of the incident. I feel like gm should cover the cost of the repair, the total cost should no fall on the consumer and the vehicle manufacturer should take responsibility for the defective part.

Ice and sludge accumulated and froze causing the cac system to fail resulting in engine issues, performance loss this was caused from gm poor design of a shield that they are aware of. Gm knows that this can happen and have now designed a new shield to prevent this from happening but it is at the owner’s expense to fix. If gm knows that this will happen they should fix the issue I am now out of pocket 3,000. 00 shame on them.

While driving at a fast pace a hazard message pops up on dash that states engine power reduced and the car goes slow unable to accelerate past 20 mph. It doesn’t happen all the time but it’s been happening quite frequently and it’s dangerous. I’m assuming there has something to do with the speed and or fuel function. The vehicle has not been inspected. I am willing to bring it for inspection if needed. I feel like this is a malfunction and I’m requesting this to be fixed.

Engine power reduced defect, causing affected models to lose power while driving at highway speeds. My son’s was driving 55 mph and then all of sudden the car decelerated to 20 mph in minutes before his 2016 Malibu stalled on the dallas texas highway. Unfortunately the car did not make it to the emergency lane and as a result a SUV hit his car killing my daughter who was 33 weeks pregnant. The baby survived with lifelong injuries. Despite this recall, gm failed to notify vehicle owners, including the owner of the vehicle involved in the fatal accident on January 6, 2024, in dallas, texas, resulting in my daughter’s death. This defect has been found in several 2016 Malibus, prompting a class action lawsuit against gm. Plaintiffs in the class action lawsuit reported having to restart their vehicles or replace faulty accelerator pedal position sensors to address the issue. Gm's failure to notify vehicle owners of the safety recall constitutes negligence and gross negligence.

My car displayed "reduced engine power" and slowed down on the highway while I was doing 65mph. My car would not accelerate past 20mph. There were no issues with my vehicle, and this happened out of nowhere. It caused a lot of other drivers to have to swerve around me, and drastically reduce their speeds as well in order to avoid collision. This was highly unsafe and now I can not safely drive my own car.

The contact owns a 2018 Chevrolet Malibu. The contact stated while driving approximately 65 mhp, the message "engine power reduced" was displayed and the vehicle decelerated to 30 mph. The contact stated that the speed would no longer exceed 30 mph. The cause of the failure was not yet determined. The manufacturer was notified of the failure, but no assistance was offered. The local dealer was not contacted. The contact stated that the failure had also previously occurred but after taking the vehicle to the local dealer no cause of the failure was found. The failure mileage was 110,653.

I was driving about 70mph on a highway trying to pass a semi-truck. As I signaled right blinker to merge back into the right lane, the speed reduced to 40mph without notice. I then seen a notification on the dashboard saying "engine power reduced". The car would not accelerate fast enough to clear the truck therefore almost causing a collision of 2 semi-trucks and myself. I was forced to drive off road to help avoid the collision. My fiancé was in the passenger seat when this happened on 11/25/2023. He then began telling me this happened to him a few months prior but he didn't mention it because it resolved itself. This was actually the 3rd time it had happened in this car over the last 2 years. I spoke to the chevy dealership about it the first time I experienced this and they advised that it had not been made a safety recall at that time yet, but the technician who helped me said his son experienced the same thing and it was becoming quite common. It still has not been recalled but there is currently a class action lawsuit because of this. I feel this is very dangerous and what I considered to be reliable transportation, is no longer the case for my family after this experience. This needs to be recalled immediately before people lose lives. Especially since the parts were manufactured incorrectly and Chevrolet had knowledge prior to releasing 2016-2018 vehicles.

My 2016 chevy Malibu that does not have many miles on it is shifting into, reduced engine power mode. When this comes on I cannot accelerate up to speeds and can only go about 25 mph. It is dangerous that my car can go from highway speeds to this slow. I have had 0 issues before this started happening and other Malibus have been recalled for this same issue.

Check engine light came on. Display stated that the engine will run at reduced power which meant we had to limp home at 15 mph which put us in a dangerous situation. I read the code and it was p2122. Throttle/pedal position sensor/switch “d” circuit low input. This indicates that there is a problem with the accelerator pedal. I replaced the pedal myself at a cost of $114. 00. I eventually found a technical service bulletin that admitted that there is a problem with the accelerator pedal on 2016 to 2018 gm vehicles and there was a program that was replacing the pedal until 2020. I called gm customer service and they said there was nothing they would do about it since the program expired in 2020.

I submitted a complaint regarding traction service/escape alerts at any given time of my 2010 chevolet malbu and have not received an acknowledgment of my complaint. Therefore I am hoping it has been resolved. Thank goodness, ithe car passed inspection on 10/17/2023 for which the complaint of the traction service alerts have affected my yearly inspection for at least 3 years. I am asking for the status of your assessment of my complaint. Thank you. Hattie overman 718-320-8254.

I'm having a problem with the car going into park. When it's in park, the doors will not lock in the vehicle will just drain the battery.

Acceleration to the engine malfunction no power to engine going excessive speeds on interstate failure light appeared car shut off one stopped car turn right back on. I’ve reported this incident of the last two years to the dealership GMC to 2016 chevy Malibu that has already had this instance back in 2019 and now has occurred at once again mileage since the last engine was replaced is 10,000 miles on the new engine.

My car is having issues driving over 60miles per hr, I have to keep pressing the gas to get the car to move, the car battery is dead and won’t turn on, I got the car repaired twice and the second time I got it repaired, it just was even worse then before . The car smells like gas , the salesman only told me that I needed a value cover gasket and he had someone repair it , but when I went to auto zone , it was still cracked, I have a oil leak and my car eats up gas.

Car looses power out of no where. No lights are on or anything.

My car decelerates and has a problem accelerating and I received a shift to park error on my instrument panel which would not allow my car to cut off leading to a drained battery and rolling. When I looked up shift to park I found that there has been a recall on chevy Malibus 2016-2019, but the dealership says there’s no recall on my car.

When driving the car and when stopping at either a stop sign or stop light, turning a corner the car will lose power and will not go for at least 10-15 seconds. When letting the brakes go and pressing the gas pedal the car does not move, pressing all the way on the gas pedal the car will take about 10-15 seconds before moving. It’s like the engine lose power and the car will not accelerate.

Lights that alert inside the vehicle at random times but more often in the last few months are: stability trek, power steering reduced and check engine. Acceleration decreased/reduced after being idle. This prompts serious danger for myself and children when there is no power being given to the car when sitting in traffic. Multiple mechanics have diagnosed the issue. Dealership gives me the run around and isn't specific with detail if check light engine goes off.

I was driving my car at a normal rate of speed when all of a sudden it slowed down to a crawl and almost caused an accident, reduced engine power and engine came one after getting the codes they were 2122 and 2097.

Reduce power engine appears on the dash board. The car starts slowing down, I can’t speed up, I have to park on the side of the heavy traffic in the highway. I have to wait around 5 minutes and then drive. I still have the engine symbol on. This happens regularly like 2 to 3 times a week.

My car has reduce engine speed. I’m driving on the highway and out of nowhere the car shots down and a symbol appears on my dashboard that says reduce engine speed. Literally the car slows down to a minimal speed until I can’t drive anymore. I have to stop and turn off the car for 5 minutes until I can turn it on and drive to my destination in a reduce speed.

While I was driving, the entire accelerator pedal mechanism fell to the ground. My mechanic told me it is because the accelerator pedal mechanism is a bad design, including too small of a bolt, and I had to have it reattached to the car. The accelerator pedal functioned, but it was incredibly dangerous because it was on the floor and couldn't be practically used.

The instrument cluster failed while driving. No gauges on dash work and the gear shift indicator light does not work. I have read online other owners with the same complaint. This should be on recall.

While driving on many occasions the last incident happened Friday April 28th 2023. My 2020 Malibu lost all communication on 231 hwy. All dash gauges went haywire power dropped on vehicle rpm was accelerated but vehicle speed would not change engine light and traction light came on. I then had to pull over brakes made a loud thud noise when stopping. Turned vehicle off sat for about 15 minutes and restarted my vehicle engine light was still on but I was about four miles from home turned my hazard flashers on and made it home. When the car loses power it gives me no warning at all it just happens. I've taken it to both chevy dealers in my area mr. Matthew at gilland GMC ozark, al explained to me that yes he saw the codes where car lost power and because they couldn't pinpoint the problem GMC had to be called and he was told that GMC has a team of engineers working on the loss of control problem but at this time they don't know anything. I'm risking my life on every day driving this vehicle in which I do have an extended warranty on but they can't fix what they can't find but yet know for fact that there is a problem.

I went to put car in park and when it was in park I was still getting shift to park alert on dashboard. With this alert I was unable to turn off the vehicle. After about 30 minutes the first time it happened I was able to get it to acknowledge the car was in park by moving my car around parking lot and shifting from drive to park. The next day it happened again but this time I had to jiggle the shifter to get it to go into park after trying for about 30 minutes. The alert basically trapped me in a car that would not turn off. I took it to the dealer service center the next day and was told it is a common problem with my car. Repair bill was $400 and told it was not a recall or something gm would warranty.

2017 chevy Malibu has p2138 showing up. . I was on the highway loss half the power to my car, almost causing a major accident, went from 65 mph to 30mph in seconds. . This is a safety issue & needs to be address ASAP!! I have my vehicle at the dealership, the service teams seems to have no clue that there is an issue with the mailbu's !! the p2138 is defined as “throttle/pedal position sensor/switch “d”/”e” voltage correlation. ” it is triggered when the vehicle's engine control module (ecm) detects that the signals from the two throttle position sensors or the two accelerator pedal position sensors don't correlate.

Purchase car in December 2018, had 3 engine replacement. I am currently in the 3 engine replacement. And still experiencing the same issue - check engine light permanently on for 2 months now. Issues a whistling sound from an opening vent in the hood since last engine replaced. Call stalls, reduces speed and jerk when trying to accelerate . Have reached out to reed lallier Chevrolet they making it seems that normal and ok. I am scared to drive and cause an accident because the car stalls before picking up. When you put the car in park, the car still not registering at park it is still moving you have to sit and clear the dash board (shift to park, even thou it is in park). Chevrolet only gave 1 engine replacement and $100 gift card. Every other expense is on me, when I still have to pay for the lemon. Unable to locate most recent engine replacement sheet. But can retrieve from dealership if needed. This car is full service and maintained in the allocated time frame reed lallier has the file of needs be.

2017 chevy Malibu over 15 times this happens since we owned buying it brand new it has "reduced engine power" error come on and the car can't accelerate over 30 miles per hour. This is a continued problem all the time and very dangerous when we are on the tollway that has a 70-mph speed limit, and you can't get the car to over 30 mph. This same problem happens on our 2018 chevy Malibu over 5 times since we owned it too and it's getting worse! this is extremely dangerous and takes you a long time to get home when you can only go 30 mph or less because of the "reduced engine power" limit. Same 2017 chevy Malibu also has the "shift to park" error so we can't shut off the engine because the car won't go into park, you have to back up and keep trying to get the shifter to let you put into park if you're lucky it will finally after many shifting attempts back and forth to get rid of the error so you can shut off the engine to exit your car. Gm should be responsible for a recall on these two very important errors that these chevy Malibu cars are having on both of the problems are very dangerous "reduced engine speed" and "shift to park" can't shut off the engine is dangerous.

The car continuously is throwing a code p2138 and a warning comes up on dash saying reduced engine power. This happened 6 times to me yesterday wherein I was traveling on 1 lane winding roads in my neighborhood so the speed drops from wherever it is down to 10mph instantly. On 1 lane roads in the area where I reside there’s no safe place to pull over. This is extremely dangerous and a massive safety hazard and risk to my life!.

Vehicle through a "service engine" and lost partial power. The vehicle slowed considerably and was not able to accelerate as expected. Fortunately, this was rush hour traffic and it was slow. Normally, the traffic moves at 60 mph plus or minus 5 mph. The loss of power on i10 can be extremely unsafe. The dealer revealed that our car had a scan code p0299. They cleaned the thottle body and stated it was the likely problem. However, they said they tested the crank case pressure and it was at 0 psi, instead of the expected vacuum. There was no indication, that crank case pressure or the pcv was the root problem. I pointed out that crank case should be measured in inh2o. I think they mis diaganosed and were trying to lead me to replace the pcv, and ultimately the turbocharger itself. I think it is probably a sensor or perhaps another component. I took my car away from the lot and will report any other incidents or findings.

When l park my car it keeps saying it’s not parked.

Car loses speed from 60mph to 15mph while driving. Engine reduce power light comes on after the fact. This is very dangerous when driving on a busy highway/interstate.

Code 2138 accelerator sensor popped up yesterday. After researching, I found out this is a common concern with Chevrolet Malibus for 2016. I'm sure you are well aware of this by now so I want to know what my options are at this point. Thank you.

Driving vehicle like normal and then the check engine light comes on with the stabilitrak light, and get message "reduced engine power". Car goes down to less than 50 miles per hour and is struggling to go must faster while I am on the freeway. The rpms keep going higher and higher even though the car is not going very fast. Get home and let it rest. Keep having same issue on and off past two weeks. Sometimes it comes on and goes off, has been on past three days acting the same way. Check engine light says pedal sensor issue. Known recall for it listed with letter sent out in 2019, but of course this was only if you were having the issue at the time (which I didn't) and it is only covering for cars under 150k miles. My car has 192k miles, so they will no longer cover it, even though it is a known issue has been for some time now! it is very expensive and unfortunate that they will not cover this issue regardless of miles, knowing that this can happen to the 2017 chevy Malibu's at any time. Still driving it the way it is. Did try to clean out the throttle body and see if that helped, but issue still is there. Will try to replace sensor at some point and see what happens.

2018 chevy Malibu over 5 times this happens since we bought it brand new it has "reduced engine power" error come on and the car can't accelerate over 30 miles per hour. This is a continued problem all the time and very dangerous when we are on the tollway that has a 70-mph speed limit, and you can't get the car to go over 30 mph. This same problem happens on our 2017 chevy Malibu that we bought brand new since we owned it too and I have already put in a complaint filed today! this is extremely dangerous and takes you a long time to get home when you can only go 30 mph or less because of the "reduced engine power" limit. Gm needs to recall these Malibu's and fix the dangerous "reduced engine power" error because it's dangerous to the driver in rush hour traffic and on the tollway traffic with no ability to go over 30 mph. All these Malibu's need to be fixed properly and its gm's responsibility to ensure safety for their customers lives.
