Common Problems with the 2018 Chevrolet Suburban

Engine Problems:

“Hello, To whom it may concern, My vehicle is a 2018 Chevy Suburban with a 5.3 motor. GM produced these motors made from inferior metal and defective lifters. My engine began failing in May 2022, I've taking my vehicle to several shops for work but the problem has not been resolved. I have links below explaining the problems with these motors. There are tens of thousands of individuals with families struggle with this same problem I'm having as well. This is world wide news, I'm asking for help for myself and so many other people in these challenging times. I've contacted GM headquarters. [XXX] and [XXX] with no success, just the run around. I went to a GMC dealer here in Clarksville, TN where I reside this month. [XXX] with GMC told me he was hearing my lifters and I need not drive my vehicle. Called me in his office and told me he couldn't get my vehicle in to be looked at, but gave me another dealership contact information. I called and spoke with a gentleman by the name of [XXX] he also informed me that they were backed up and couldn't see me until October 5th. All warning lights came on in May of 2022, engine and steering and traction. Please view these links below that explain in further detail. Thank you for your time and help!

“The vehicle began to shake as if it would shut down. Then, the engine light came on. Then I received three text message alerts. We were shown paperwork regarding the service history that was done at Philips Chevrolet. Now we’re getting alerts regarding work that has to be completed within 7 days.”

“My wife and son were traveling on the interstate in Indianapolis and the brakes began to fail in our 2018 Chevy Suburban. The brake pedal was almost impossible to depress to get the vehicle to even slow down. She was afraid that she was not going to be able to stop and get in a crash. Fortunately, she was able to maneuver the vehicle to the shoulder as it finally slowed down enough. She was afraid to go any farther to an exit for fear of not being able to stop down a sloping exit. So she was able to come to a stop on the shoulder of the interstate. Their was a warning light that came on as this was happening, which was the ABS warning light. It was towed to Andy Mohr Speedway Chevrolet and they have diagnosed it as a failed vacuum pump. After doing research, I found that there is a recall on 2018 Chevrolet Suburban for the vacuum pump. However, the VIN on my vehicle wasn't included. The recall number is N192268490. The information listed in this recall sounds exactly was happened to our vehicle causing the very dangerous condition that could have resulted in a tragic crash.”

Powertrain, Transmission Issues:

“On two occasions, most recently on 6/13/23 the vehicle went from 70 mph to 10 mph very suddenly on an Interstate in heavy traffic--very dangerous. The display indicates an overheated transmission but the dealer believes its some electrical problem. This 2018 Suburban has an 8 speed auto transmission which has a lot of on line complaints and lawsuit pending.”

“Vehicle started shaking while accelerating. Independent mechanic and his recommended transmission shop diagnosed an issue with the transmission - specifically the torque converter. Shop said the car was unsafe to drive while waiting for new transmission as it could lose ability to accelerate while driving. When I asked the transmission shop if they felt the previous owner(s) may have abused the car with their driving to cause the issue at a relatively low mileage, they said this was a systemic issue with this vehicle. In fact one of the repair techs had the exact same issue with his personal vehicle at similar mileage (same make / model).”

“We were driving the 2018 Chevrolet Suburban with our three children we tried to accelerate at a green light the car jolted to a halt and someone almost hit us from behind. If this would have happened on the highway we could have caused a major accident and put my kids lives in danger. Was able to get the car to move to the side of the road. We had the car towed to an automotive repair shop and they said there was an issue with the torque convertor and the transmission was totally ruined. There were no check engine lights and no warning what so ever! The repair shop said they haven’t seen this happen on a car with so few miles. Costing us 4.5k and a couple weeks. There are no recalls for this issue on our car.”

Electrical Problems:

“While driving the vehicle lost all power and after about 20 seconds power came back on. The repair was the battery cables which was apparently very common on the make and model of vehicle. It's unsafe and can cause an accident and apparently happens on the majority of vehicles same year and make.”

“Car has been at dealer 3 times for Wi-Fi issue. Mechanic took car home for longer drive to check. No found issues. Brought in for small noise that comes and goes. They Came back saying $10000 for cam shaft and lifters they are assuming.”

“My doors lock with the car with the keys in the car, my kids were in my car and I got locked out with my keys in it, there was a battery replacement done when I took my car in for a recall notice a month ago (maybe 2 months), also the lock button works but when I push the middle button it will not auto start, when I push the button on the handle outside the car door it will not unlock, & my car will tell me that my remote isn't detected when the keys are in the car. I was at home when it locked with my kids in the car I put them in the car and I walked around to the other side of the car and it locked that quickly in my driveway at home not even running not moving.”

Brakes Problems:

“Vehicle starts dinging with warning - Service Trailer Brake System - and warning - Action Required Steering Assist is Reduced Drive with Care - ABS Light - Traction Control. Power steering goes out and assumedly ABS and Traction Control stop working.”

“My car was acting weird, brake pedal was extremely tough to decompress, speed then was affected, and ultimately the brakes failed.”

“Car brakes on its own when going above 40 mph causing the vehicle to pull to one side.”
