I am very upset right because I purchased this Chevy Malibu 2016 from Vroom. It was fine at first and then things start to go downhill. For starters my tire light came on first only a week after having the car, then the shift into was appearing on the dashboard as well as the engine light. Then my husband spent almost 2000 on the brakes because the car was making this horrible sound and I almost couldn't stop the car because the pedal was stuck and would not push down. Thank God no one was hurt. Then my car just shut off twice one day at a busy intersection, it went completely dead with my children in the car. This is a ongoing issue. Now I had a diagnostic test ran on my vehicle and it was said I needed a new motor only after having the car for only a year. This car is very dangerous and I wish they would take it off the market, because it will also reduce your speed while driving out of nowhere. Chevrolet should be responsible for all problems before they are aware of these issues!

I took my car to to Firestone to have the brakes checked because I had a stiff brake pedal and could only use my emergency brake to stop. They did a basic and advanced diagnostic and said that the brake booster that I have has been recalled and also other equipments on my car has been recalled and I must bring it to a dealership. I searched my VIN and nothing popped up even though months ago I was emailed a recall notice on the fuel pump system and Air bags and it has never been repaired in my car even from the past owners.There have been 10 recalls from Malibu's manufactured in 2016 and my car shows every sign and indication that it is one of those few selected. My VIN should be updated or investigated for parts in my vehicle that have been recalled. The Car stops when idle for two minutes or longer and shuts off the engine and air if you use the USB outlet there is a serious electrical problem which is also a safety hazard according to NHTSA guidelines.

My 2016 chevy Malibu had brake vacuum pump failure. No warnings. Brake pedal got hard and could not stop. I was returning home with my 13 yr. old daughter from Tennessee and had to get it fixed so we could get home. Mechanic said this is a common problem and that there is a class action lawsuit on this problem with these cars about having a recall. This put me out of pocket $1986 dollars which is unacceptable and could have ruined my entire engine.

I just bought this car 2 weeks ago. Had to replace the windshield wiper pump. There are at least 10 TSBs on the vehicle I'm on disability I can't afford to fix all that. The rear hub bearing was barely making noise when I bought it. Now tire feels like it's going to fall off. I believe there's a TSB on when you put the car in park and shut it off then it's not going in to gear even though it said it's into gear so I have to get that fixed as well. Can't Chevy fix thermostats just like I have to fix my mistakes in life.

#1 3rd brake light leaking into back seat and trunk manufacture bolts backed out and/or missing, can also cause water to get into the brake light which tends to cause 3rd brake light failure, increasing risk of a crash. #2 gear shift lever inner lock blocking the ability for user to shut the vehicle off, this can also cause the gear shift lever to indicate vehicle is in park, but the transmission may actually be in another gear. This can lead to damage to the transmission or increase the risk of a crash. A recall has been made for Chevy Malibu 2016-2020 but my VIN was not included. While my vehicle is experiencing these issues. Issue was confirmed by an independent service center. Shift to park message pop up on dash when attempting to shut vehicle off unsure of exact start date but started a few months ago. I have since been doing my research on issues and their solutions.

My vehicle has not been inspected, but while I was driving the brake pedal became stiff, luckily my e brake was able to prevent any wrecks. I saw that the 2016 chevy malibu has a known issue with the, "ebcm" and that would certainly cause these kinds of issues, my brake pads and rotors still have plenty of life left. Also, the driver side seat switch stopped working, according to reviews by other 2016 chevy malibu owners, and mechanics, that's because of the design flaw in the switch, it somehow rubs itself raw until there's nothing left and it snaps, leaving the switch nothing to grab on to. So, my driver seat is stuck, all the way reclined, and all the way forward. Which, according to the manual in my malibu says is a safety issue, because of the design of the seat, if it's reclined while driving and there is a collision, it can cause the seat to slide, which can cause serious injuries or death, I'd say that goes for both though.

The brake booster pump needed replacing because of malfunction. I was driving on Fredrick Douglas bridge and needed to brake.. when I tried to brake, the brake pedal was very stiff (alot of pressure) and it took awhile just to slow the vehicle down. I had to apply all my force and push the pedal all the way down to try and slow the vehicle. The break pedal continued to stay that while I had to drive very slow to get to a safe place where I can park and wait for a tow of the car. The tow truck driver experienced the same problem trying to get the car up on the tow bed. My mechanic also experienced the issue with my car. No warning light was given on the dashboard at all. I took a look online and saw there were numerous complaints about this issue and Chevy has not issued a recall notice of this defect.

In November 2022 my vehicle (2016 Chevrolet Malibu) experienced a vacuum pump failure resulting in the brake system being inactive. Once the brake pedal was pressed, it remained locked and further stopping was not possible. Luckily I wads able to stop onto the shoulder, however it was on a busy highway where I was nearly unable to stop as we were merging from an exit ramp with no emergency area. Both myself and my girlfriend safety were at risk of injury had we not been able to safely pull over. After being towed to an auto repair shop the vacuum pump was replaced with no issues experience until 4/2/2023. As of April 2023 this same error occurred once again after entering a busy area. A second time I was lucky enough to have been away from traffic, however it could have resulted in personal injury or the injury of another individual had I not been able to pull off into an emergency lane. The car has since been towed to a certified Chevrolet dealership where I am awaiting an estimate on repairs. Initial review from the mechanics state damage has been done to the brake boosters as well as to the cars cam. Estimates on repairs could be as high as $5,000 or more including labor, diagnostics, and parts. Prior repairs done in November were nearly $700

I was parked idling in a parking lot for about five minutes. I went to leave pulled out of the parking lot, hit my brakes at the light and it sounded like my whole front end was going to fall off the brakes had no pressure and it sounded like it was metal on metal, I had to get home so I thought I could take the long road home that has barely any lights on it. By the time I got down the road they were back to normal and now it-??s done it twice again. I also have some electrical stuff happening where my radial to shut off or not work at all. Also had a couple pistons that had to be replaced earlier and they tried to get me for failure to maintenance but I took my car in faithfully every time I needed oil and I also took it in early because I was using fully synthetic had another 2000 miles to go for me to not have any oil in my car was ridiculous. They ended up only charging me for the seals, but in the beginning it was like 3900.

After driving during the morning with no prior issue with brakes I proceeded to drive along a residential street going 15 miles per hour. When I began to press brakes while approaching a Stop - the brakes began to grind horribly, I let up off the brake and pressed again, same sound (grinding as if something was going to fall out the bottom of the vehicle around the pedal). I put the car in reverse and brake again, same sound, tried going forward a bit further, same grinding sound. Car seemed to be Immobile, undrivable. Called a tow immediately and towed to dealer - they kept vehicle overnight but the issue could not be duplicated while in their possession. They inspected the brakes and found nothing wrong. I picked up car but felt it was unsafe to drive so I drove only local area for the next week. The same issue occurred while leaving home about 1wk. later. Car was not drivable - brakes were hard and grinding horribly. I towed the car a second time immediately to another GM Dealer. The vehicle was kept for several days, the issue would not repeat itself @ dealership so it went undetected (they actually insisted that I needed a battery and a dead cell could cause the issue I was having and more) While this mad no sense, I went in to the dealer myself and drove the vehicle around the lot until the issue occurred again. The Technician came out an said, that's horrible and unsafe I know exactly what that is, it's the BRAKE Booster and it was very dangerous to drive like that. This faulty issue could have resulted in an accident had I been on the expressway, or even worse. it took 2 tows and 2 Dealers to find and confirm the issue. This issue is a dangerous hazard and - there should be a Recall on the BRAKE BOOSTER! It resulted in a costly $$ and dangerous hazard that could be avoided by having the vehicle recalled. e.g. engine light displayed intermittenly when this issue occurred but the Dealers were unable to detect the issue or any diagnostic problem.

The brake booster vacuum pump failed, twice. There wasn-??t any warning messages prior to the failure. It is available for inspection. Both incidents happened on the freeway, which put mine and other drivers at risk. The first time it failed was in July 2022, then 3 months later in September after being repaired, failed again. The problem has only been confirmed by multiple mechanics. Not only did the vacuum pump fail, it-??s extremely difficult to find a replacement part, new or used.

The morning I started my trip. My back up camera stayed on. I stopped turned the car off and back on. It was still on. Turned it off again. This time the camera went off. I was going up the cajon pass. No warning light or anything. Was coming up to my exit. Tried to slow down to exit. Couldn't press my brakes. They were rock hard to press. Took my foot off gas. Slowed down enough to get to the shoulder of the road. Once I was able to stop. My brakes were hard to press they made a clunk noise. I noticed the check engine light was on. I could of been killed had someone been in front of me and stopped. Or I could of killed someone. This is not the first time these brakes have done this. They did it earlier this year I wasn't able to press my brakes as and when I was it made the same noise. I had it towed to dealer to be fixed. They said they fixed it. This could of killed me or someone else as I was traveling on the freeway at faster speeds than the streets
