The contact stated that the brake pedal went to the floorboard while stopping the vehicle. The contact then stated that after pulling into a parking lot, the contact attempted to restart the vehicle; however, the vehicle failed to start with the check engine warning light illuminated. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired. The dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 111,000. | Crash: No Fire: No Towed | 111,000 |

| Dec 2025 | SERVICE BRAKES | The brake booster unit, vacuum pump , brake light switch failed and malfunctioned and it is available. My safety and others on the road was at risk due to brakes being stiff and hard as a brick. Possibly nearly hit an other vehicles on the road. No warning lamps or other symptoms prior to the failure. | Crash: Yes Fire: No Injuries: 1 | Unknown |
| Nov 2025 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FUEL/PROPULSION SYSTEM | After diagnostic troubleshooting from DTCs on a check engine light, it was discovered that the brake vacuum pump connected to the engine was completely nonfunctional. Previous symptoms included stiff brake, loss of brake power at random brake periods which could have cause and accident with other drivers, and finally malfunctioning sensors attributed to the exhaust system. This also led the vehicle to be unable to pass state regulated Emissions testing because of the inability to maintain proper emissions levels. Brake Vacuum pump that was removed from vehicle to inspect and diagnose is still available for inspection. Recent findings show that Chevrolet/GM is aware of the issue in their vehicles but refuses to address or replace faulty brake vacuum pumps. It is a common problem amongst 2013-2022 Chevrolet Malibus. Vehicle that is in question was inspected by a certified mechanic shop with failed emissions test. Solid check engine light appeared once the brake had become harder to push and stop the car. OBD scans show DTC codes that were pertaining to MAF and MAP malfunctions in readouts and communications to the ECM. After further inspection, the ABS module had been acting as "backup" for hydrolic brakes system that had zero vacuum to power the brake booster, this could have caused the engine to stall, longer than normal stopping distances (stronger risk of rear ending other drivers), and multiple components and sensors to fail, requiring them to also be replaced. | Crash: No Fire: No | Unknown |
| Nov 2025 | SERVICE BRAKES | The vacuum pump for the brake assist is made from bad metal which can break and screw up the camshaft, chevy knows of this problem they have a recall for the 2017 model but not the 2018 which they both have the same exact problem, they need to take care of this it is a major safety issue, I have no brakes and it could potentially ruin my engine. | Crash: No Fire: No | Unknown |

| Oct 2025 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM | Every so often I get an indication of engine power reduced, but every time I go in to get it checked it's off. I have recently just learned through research online that the issue is caused by a certain condition that gives false reading to the electronics. I have contacted GM and GM financial about the recalls on my cars of the same year. I have not been in a wreck but I have had the issue of engine reduced power in the middle of traffic. Cox Chevrolet in Bradenton has turn me away about the issue GM financial is giving me the runaround neither one mention anything about a recall instead I get a estimate $400 /$808.50/1900.41 all to fix ECM as I told the mechanic I was driving with no problem through the day me and the kids at the park when it was time to leave the car sounded like it just didn't have no gas. We was stuck tell 10:45 we waited two hours for the tow truck. I have OnStar and get monthly reports on my car. When the check engine light comes on OnStar has no indication that's why I believe it is the same ECM. I was told by Chevrolet Maher service manager of St Pete to get my car off their lot as I said before I got a estimate of 400 that went up to 800 and all I did was ask why | Crash: No Fire: No | Unknown |

| Oct 2025 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | Purchased a car for financing from Barret Motors and 2300 Lakeview PKWY, Rowlett, TX and as soon as I drove it off the lot on [XXX] the engine light popped on. I immediately called and was told to just take it to Chevy/GMC for servicing but was not told why, but just because the engine light was on I was told to go. I couldn’t take an appointment asap because I just started a new job which they also knew. The car has had a recall since 09-06-19 for an engine control module. Which is a serious issue and this car never had it completed and sold me a car with possible engine issue and did not inform there’s a recall on the vehicle for almost 5 years now. I took the car to get serviced at Chevy for the recall on 09/09/2025 and now I am facing multiple issues with the car from it not being done years ago. The recall was N192221960 and it’s major so to sell a car before getting the properly service and I have been financing the vehicle for a year now. Never not once late and I am now being told there’s nothing can be done. I have photos of the car having the engine light pop on the same day u financed this vehicle. Barret knew a serious engine problem was effecting this car for 5 years and still deciding to sell it to me for financing on [XXX]. I need immediate assistance.

| Oct 2025 | SUSPENSION,VEHICLE SPEED CONTROL,SERVICE BRAKES | The rear knuckles on these cars are constantly going bad and the parts are expensive and so is the labor. So we have to pay a fortune to fix a common issue that GM should be recalling and fixing for the people who buy these vehicles. It's crazy how common this issue is and it's still not recalled. If you hear a clunking/rattling noise coming from the back of your car then it's almost certainly a knuckle problem. | Crash: No Fire: No | Unknown |
| Oct 2025 | SUSPENSION | I keep hearing a clunking noise in the rear of my car and it gets louder at low speeds and when I turn when stopped. I have been doing research to try to see what it could be and I am seeing that this is a common issue with this car and there's no recall. The parts alone are $200+ and then you have to pay for labor. This is ridiculous for a faulty assembly problem due to GM. | Crash: No Fire: No | Unknown |
| Oct 2025 | UNKNOWN OR OTHER | SHIFT TO PARK ISSUE | Crash: No Fire: No | Unknown |
| Sep 2025 | ELECTRICAL SYSTEM | Hello, I own a 2018 Chevy Malibu. I previously had the recall repair completed for ECM Malfunction. Unfortunately, I am still experiencing the same problem that the recall was for. Since then, the issue has returned, and I am concerned that the original remedy did not resolve the safety concern. Can you please advise me on the next steps to have this issue re-inspected and corrected? Thank you for your time and assistance.

| Sep 2025 | POWER TRAIN,UNKNOWN OR OTHER,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN | 1. This case refers to a 2018 Chevy Malibu. In October 2021, the (gear shift) transmission control system was found faulty and was replaced with an N-CONTROL in the gear shift. Again, in September 2025, the same issue happened, this time replacing the N-CONTROL again as well as the N-HARNESS. Yes, can be available upon an inspection request. 2. This component directly affects how the car recognizes when it is in Park. When it malfunctions, it can confuse the vehicle’s electronic systems and potentially prevent the car from shutting down properly, engaging the shift lock, or starting safely. This creates a safety risk for both me the driver and others around my vehicle. Since this is a recurring issue as well as other 18 Chevy Malibu's I don’t believe this is normal wear and tear. Having to replace the same system twice in such a short period suggests a recurring failure or a design flaw. 3. Yes, the problem has been confirmed twice by Chevrolet dealerships on both occurrences. 4. Yes, the component was inspected by two Chevrolet dealerships during both occurrences. 5. Had warning message "shift into park" both times in the month the car was taken in to be inspected. | Crash: No Fire: No | Unknown |
| Aug 2025 | STEERING,SEAT BELTS,UNKNOWN OR OTHER | Steering asst warning came on. This happened in 2022 when I got the vehicle and it’s now happening again. When stopped with foot on brake and auto stop engaged , you take foot off brake steering wheel jerks and steering asst warning comes on. There is also a problem with shift to park. Vehicle shifted into park vehicle doesn’t recognize that it in park and vehicle can’t be shut off until it recognizes that it’s actually in park. Chevy knows this is an issue and will cover it under bumper to bumper warranty but will not fix it under a recall or outside of bumper to bumper warranty. Vehicle has a p1101 code that comes and goes. Engine filter has been replaced, throttle body has been cleaned, MAF sensor has been replaced, and the issue continues to persist. There is no know way to fix this. Rear seat belt doesn’t work. Vehicle came like that. Vehicle has had multiple issues. Contacted Chevy they want me to pay for a diagnostic out of pocket and submit to them and possibly they will then help. These are all known issues that they are not addressing. | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER | The car is saying “shift to park” on the dash panel as if the car is not in park. Sometimes this continues to read to the point it will not let you shut the car off and then you can’t get out of the car. This is a safety concern as well as an issue with the car wanting to continuously run. | Crash: No Fire: No | Unknown |
