Engine And Engine Cooling Problems of Chevrolet Malibu - part 1

Engine power reduced car shuts off and will not start.

See all problems of the 2018 Chevrolet Malibu 🔎.

My vehicle sometimes will not start when I press the start button and press the brakes at the same time. The dashboard will light up with a message that says “service esc” followed by “engine power is reduced”. When it does start, I can drive the vehicle for a moment before it does the engine power reduced mode where the car feels like its pulling more. It has done this several times while I’m driving on the highway which often times causes me to have to pull over to the side of the road, or make my way to the slow lane so I can pull into a gas station or somewhere public at the next exit. When the dashboard lights up with “service esc”, all of the hands on my dashboard (I. E the hands for the speedometer, gas, the car temp and the rpm) move radically back and forth while the car is driving. Sometimes the speedometer will say 0mph even tho the car is moving. Sometimes I am able to pull over and turn my car off and back on and the lights will go away, but often times this doesn’t solve the problem. In fact, it feels like it only exacerbates the problem because when I shift it into park and then attempt to turn off the vehicle, it says “shift to park” even though it is parked. In fact, this morning when the vehicle wouldn’t start after I tried to start it with the button, I attempted to turn the vehicle off (because the radio would come on and I can see lights on the dashboard, but the vehicle itself won’t start) and it said “shift to park” even though it is parked and has been since last night. I contacted the nearest chevy dealership and they informed me that they have dealt with plenty of these complaints lately. I have not had an inspection completed by the dealership because my extended warranty is up and I do not have the funds to pay for a diagnostic inspection.

Purchased the car February 14 2025 with 102,664 miles on it. About 2 weeks ago I was merging on a highway and it went into limp mode and I almost get rear-ended. It felt like it lost all power. The check engine light came on and I drove it to auto zone to have it scanned and code p0299 was the code, turbo underboost. I then went to o'reilly's for a second opinion and their scanner also said turbo underboost. I have replaced all sensors that interact with the turbo thinking maybe it was a sensor but negative. Turbo failure.

The contact owns a 2018 Chevrolet Malibu. The contact stated that there was a strong fuel odor coming from the vehicle. The contact stated that the engine was difficult to turn over. The tpms warning light was illuminated. The vehicle was taken to an independent mechanic who determined that the fuel injectors were leaking. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 123,074.

While driving, the vehicle experienced a mechanical failure involving the engine and lubrication system. Oil leakage was observed, and the engine began operating abnormally. This created a risk of sudden engine failure while the vehicle was in motion, which could result in loss of power, stalling, or loss of control, especially at highway speeds or in traffic. Prior to the failure, warning signs included abnormal engine behavior and fluid loss. The issue was not caused by driver error and occurred during normal operation. Continued operation in this condition presents a fire risk if oil contacts hot engine components. The problem has been inspected by a repair facility, and the failure appears to be related to a mechanical or manufacturing defect rather than wear or misuse. The component is available for inspection upon request. This defect poses a safety risk to the driver, passengers, and other motorists due to the possibility of sudden engine failure, loss of propulsion, or fire.

Reduced engine power. Car will not accelerate over 35 mph. Almost rear ended. Will be the second time in dealer for same problem. Also, shift to park. Also second time at dealer for same problems. You cannot get out of car until you keep moving the shifting handle.

Dear NHTSA: I am submitting this complaint because my vehicle, a 2021 Chevrolet Malibu (VIN [xxx] ), is included in emission recall n252516900 issued by general motors concerning the fuel pump power control module. Despite that inclusion, I have experienced the following: - a prior near-fatal incident in 2023 when the vehicle unexpectedly shut off while stopped at a red light (engine stall) due to the root defect. - the dealer has informed me I now need a new 12-v battery (just over one year old), a new ac compressor, and a new drive/serpentine belt. - the defect referenced in the recall (interruption of fuel flow) is reasonably the root cause of these consequential failures (battery stress, accessory drive stress). - I have been without the vehicle for 11 days, have not been provided adequate interim mobility support, and have not received timely resolution from gm under my case #xxx (agent jasmine who has followed her company's protocol while remaining helpful and empathetic; supervisor stephanie called October 17, 2025). Requested relief: 1. That gm be required to pay for the recall work (module replacement) *** reimburse/cover the consequential damage (battery, compressor, belt). 2. Interim remedy: loaner vehicle or rental reimbursement for days without vehicle. 3. Acknowledgment of the safety risk posed by the defect and record of the stall incident. Thank you for your attention to this matter. Sincerely, [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I get a engine power reduced warning and check engine light is on for 3 start cycles and goes away. Auto start/stop after stopping, lights flicker and power is slow to come back on upon auto start and I get a power steering reduced warning. ,.

Engine power reduced, my car then loses the ability to pickup speed I’ve even had my break tighten up on my in the middle of trying to stop my vehicle.

Multiple components and/or system failures/malfunctions, exact cause is unknown. Vehicle is available for inspection upon request. Safety risks include engine power reduction issues that result in unexpected deceleration, and/or sudden/dangerous loss of power/acceleration. Problem has not been reproduced or confirmed by a dealer or independent service center. Vehicle component has not been inspected by the manufacturer, police, insurance, representatives, or any others other than diagnostic trouble code testing at o’reilly auto parts due to illuminated check engine light. Vehicle displays error messages “engine power reduced,” while driving and/or idle, and “shift to park” when vehicle has already been shifted into park. No obvious symptoms of the problem prior to failure, unknown when first appeared. Vehicle-2018 Chevrolet Malibu lt l4-1. 5l 1490cc 91ci gas di turbocharged VIN t lfv-4 valve dohc (mileage-145000). Primary powertrain diagnostic trouble code “p0014 - exhaust camshaft position system performance (code p0014 indicates that the bank 1 exhaust camshaft position timing was advanced beyond limits for a predetermined period of time),” with additional powertrain diagnostic trouble codes “p0011 - intake camshaft position system performance,” and “p1101 - intake air flow system performance. ” also receiving abs diagnostic trouble code “u0422-71 - invalid data received from body control module - invalid data. ” suggested solutions included “replace variable camshaft timing (vct) solenoid,” and “replace variable valve timing (vvt) solenoid. ” believed to be related to NHTSA id numbers 11643630, 11586483, 11581989, 11569471, 11568501, 11565871, 11564692, 11635526, 11457416, 11420146, 11416774, 11325303, 11561528, 11559451, 11555493, and approximately 30 other related NHTSA id numbers for same error message(s), and/or problem code(s), NHTSA campaign number 19v642, NHTSA campaign number 19v642000, gm special coverage number n182188250, and gm recall number n192221960.

My 2016 Chevrolet Malibu limited (VIN: [xxx] ) experienced sudden loss of power while driving on 9/11/2025 and set code p228c. The dealership diagnosed the problem as the bolts coming loose from the high-pressure fuel pump, which caused the pump to detach from the cylinder head and become damaged, requiring replacement. This failure directly matches the defect described in NHTSA recall 18v-358 (gm campaign 18188/18268). That recall explains that the high-pressure fuel pump can detach from its mounting due to a weld failure, leading to oscillation, damage to the fuel system, and an increased risk of fire. Although the dealer phrased it as “bolts came loose,” the result is identical: the pump detached from the cylinder head and damaged the fuel system. Despite this, my VIN does not show an open recall. Gm customer assistance told me the repair would not be covered because of the vehicle’s age and mileage (current mileage 129264), even though recalls are federal safety obligations that are not limited by warranty coverage. I am requesting that NHTSA review this exclusion and ensure recall 18v-358 coverage applies to my vehicle. This defect creates a serious safety risk of fuel leaks and fire. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Received vehicle at roughly 181,000 miles. Operated fine for about 5,000 miles and then began to show problems. In most cases when pressing down hard on the accelerator pedal, transmission drops into a lower gear and revs up to 5k rpm, cancelling cruise control, and staying there until accelerator is relieved. This makes accelerating more difficult since too much pressure on the accelerator pedal causes the car to get stuck at 5k rpm and stay at the same speed it is already at. This makes passing cars more dangerous as the car gets stuck at 5k rpm and can't pass the other vehicle, increasing the risk of a head on collision. Service engine and abs lights are on as well as a service stabilitrak notification in the driver information center. In addition, the outside temperature thermometer is faulty and shows much lower temperatures, such as -14 degrees during an 80 degree day. Vehicle is up to maintenance as far as my knowledge goes. Car has been previously junked twice and has a rebuilt title. There are no fluid leaks, the engine works well when the problem is not encountered, but it gets stuck at 5k rpm under hard acceleration more than it doesn't.

Vehicle experiences a loss a power will driving. A lawsuit for defective throttle control and pedal position sensor was filed but eventually dismissed. Gm is aware of the issue but has done nothing to fix it.

Throttlebody hose pops off of the throttlebody due to a missing gasket ring as well as the retention clip/spring clip. The plastic pieces on the spring clip have popped off since the issue has been presented. Cannot accelerate past 3 1/2 rpms without throttlebody hose popping off from the pressure produced by the turbo charger.

Vehicle is registering multiple keys from surrounding like vehicles which causes the anti theft system to activate, disabling the vehicle and/or involuntarily draining battery.

My 2019 Chevrolet Malibu has severe safety defects involving the engine, powertrain, and speed control. The vehicle will sometimes accelerate on its own with my foot off the gas, and other times it loses all power while pulling into traffic. This creates an immediate risk of a crash. Multiple diagnostic codes appear repeatedly, including p0299 (turbo underboost), p0101 (mass air flow performance), p1101 (intake airflow performance), and p0506 (idle control rpm too low). The charge-air hose repeatedly blows off the throttle body while driving, causing sudden loss of power. The vehicle was sold to me by a dealer as safe and reliable, but these defects appeared shortly after purchase. The unintended acceleration and sudden loss of power make the car dangerous to drive. This appears to be a serious mechanical and safety-related defect that could cause an accident.

I was driving my car on the highway doing 65 mph when all of a sudden my car started rapidly jerking losing the power to accelerate and entering “limp mode“ there was multiple cars behind me when my car lost the power to accelerate. I was in the far left lane and couldn’t even go higher than 7 miles an hour and had to cross across three lanes at 7 mph on a 65mph highway to pull over. I had my children in the car and almost caused a huge accident dude to this issue. The issue in hand is the vacuum pump. It completely shattered in my engine, causing severe engine damage. And it caused my brake pedal to become hard as a rock. I couldn’t break without using my emergency break. I had no brake power at all. My car had to be towed.

The fuel pressure system is faulty and shutting the engine down and reducing speed.

Th e brakes are not working at all. We have to go slow then the brakes are hard to press. Th I s makes it keep driving anc brake pedal doesn't stop it.

Check engine light came on. Took car to autozone and o'reilly's to be given the same p0299 code which is a failed turbocharger. Reduced engine power, car goes into limp mode. Gm has issued a special coverage program for 2022 chevy Malibu as of Nov 2025 but for some reason my car is not covered!!.

Vacuum pump blew . Causing me to lose brakes on the highway. It led to a series of events. Camshaft broke in the midst of this so my car will not start again.

Vehicle stalls at lights and in traffic because of the start / stop system gm has put in this 2019 Malibu. This is dangerous as the vehicle moves if on incline (sometimes backwards). There is no control. The vehicle then has to be shifted into park and then restarted. This happened July of 2024 and August 2025.

When I put my car in park and turn it off, I get the message to "shift to park" my engine light is on and sporadically goes off. It is difficult to bring my car in as there is a fee to evaluate my car and the sporadic engine light. When it is on my chevy app tells me it is engine and transmission - air induction system.

Engine reduced power light on dash. Vehicle stalling.

Okay so my car had 2 recalls but the they were not repaired the same problem reoccurred . Which was the car engine not turning on and electrical problems etc. I don’t really know how to explain it but yes it’s having the same problems .

Shift to park issue and fluid mixing in with engine.

!engine power is reduced.
