2018 Chevrolet Malibu

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.

The contact owns a 2018 Chevrolet Malibu. The contact stated while driving at various speeds, the rear end of the vehicle made an abnormal popping and clunking sound. The vehicle was taken to the dealer, where it was determined that the failure was related to TSB Number: 18-NA-136. The dealer provided an estimate for the repair, but the contact declined to pay for the repair. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the dealer had confirmed that the vehicle was not covered under the TSB. The failure mileage was approximately 75,633.

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.
