I've taken my car in now 4 times to Chevy dealers just to be told there was nothing wrong. Turnes out that my torque converter (transmission) is going bad. And I can't get a Chevy dealer to honor my almost expired warranty.

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.

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.

My car has auto stop and every time it cranks back up my radio blinks off, my lights blink off, all the lights on my dashboard come on and the error message Steering Assist is Reduced comes on the message center. Sometimes it doesn’t want to crank back up. Today when all that happened the message service stabilitrac also came up. I can’t find any recalls.

I have a 2018 Malibu with a very long list of major issues. The Engine loses power constantly along with a “Engine Reduced Power” warning and check engine light. I get a constant “shift to park” message even after placed in park. All the steering wheel buttons/controls do not work. With the exception of the cruise control. Car almost red lines after the power message displays when you try to increase the speed of the vehicle. The back axle/suspension/hubs make a very loud popping sound when I back up or drive forward. Both back wheel assemblies make a very loud wobble noise when driving. Almost like the assemble is going bad. The Auto Stop/Start causes a lot of issues. It causes the car to jerk horribly and that’s when you hear the popping in the back axles the most. Idk if there is an option to turn this off in this model. But, if there is I can’t access the message center because the steering wheel controls/buttons don’t work. Also upon restart the car runs extremely rough and tries to die. The car has really bad powertrain issues. The car not only loses almost all power….. but, also acts like the transmission is slipping when taking off from a dead stop. Causing it to jerk really bad when the transmission actually catches. The brake system also seems like it has a lot of issues. Here recently the brakes seem like they don’t want to stop the car and that leads to pressing the brake pedal down harder resulting in the brake finally stopping the car in almost a dead stop. This could cause a rear end collision or a collision after your designated stopping point. Every time it rains my trunk gets soaked with water leading to a horrible mildew smell and damaged property in the trunk. Also, the steering wheel will start wobbling uncontrollably when driving down the road and then just stops. It causes a violent shake in the front end until it stops. I’m sure I missed a few things just because of how long the list is. I’m hoping for a solution to these problems.

“Engine power reduced” shows on dash after I’ve taken it to the dealership. I’ve been on the highway where the speed slow down drastically cars coming behind me! Very dangerous! Also “shift to park” displays when it is already in park! Have to either wiggle the gear shift or, turn car off/on several times for the message to go away. Also when backing up, there’s a popping noise in the rear. Dealership acknowledged I want the only customer with this issue. Claimed they didn’t find anything wrong. I purchased this vehicle in 2019 and it was only a year old. Issues started almost simultaneously at the end of 2019…Too new for all of these issues.

When car restarts after being in Auto stop start mode the steering wheel jerks uncontrollably. The car obviously has a suspension problem. Dealership failed to repair issue properly after several attempts. Also appears dealer made false diagnosis to prevent repairs under bumper to bumper warranty. GM Dealer also refused to repair issue under Power train warranty. Another dealer wanted $555 just to check issue. A couple of weeks ago I suddenly lost control of the vehicle. I was at a red light. Car went into auto stop start mode. When light changed and car restarted, as I proceeded to take off the steering wheel jerked away from my hands, and I lost control of the wheel and car. Luckily it was a single turning lane and no other vehicle was next to me turning. I pulled off side of the road in shock. I drove about half mile and warning light displayed on dash. Warning Message States STEERING ASSIST REDUCED DRIVE WITH CARE" what was a brand new 2018 Chevrolet Malibu purchased in 2019 is now unsafe and inoperable. This steering component issue along with several others were brought to dealerships attention and were not acknowledged and were dismissed. After several other failed attempts this dealership purposely ignored this issue months ago while car was still under bumper to bumper warranty. Dealership also refused to repair this issue under powertrain warranty. 2018 Chevy Malibu has had 5 recalls to my knowledge. This has been spontaneously producing white smoke from underneath the hood on several occasions. I have video and witnesses. This car was sold as a brand new car. This car had recalls at the time of purchase and never disclosed the recall information. Also be advised that I cranked the car today just to keep the battery in tack because car has been sitting since June 10. The car choked, head lights went flickering, car could barely stay on. it appears to be an engine issue. These cars should not be on the road. They are not safe.
