2018 CHEVROLET SUBURBAN Complaints

I've taken this SUV to the Chevy dealership 4 times now for the same issue. SUV will not start at times then starts, it will even turn off on the road without warning. New Battery and Chevy can not find out issues $500.00 later. The brake pedal becomes hard to push down, and it will not start: wait 10 mins or so and it will start. Even the remote start at times will not work. Chevy has had it for 30 days at a time and I'm being told to bring it back when it happens, how do I that!

Transmission has to be replaced due to transmission slipping and delayed shifting under heat and prolonged highway driving. This issue also causes SUDDEN hard shifting, hard breaking, shaking of the steering wheel, along with grinding of gears!! This is a safety issue to to no warning signs at all along with a sudden drop in speed and power!! While driving on the interstate or highway this sudden change can cause the vehicles behind you to rear end you or cause a pile up!!! The driver has no control of vehicle when these issues happen!! A loss in control due to shaking of the steering wheel is a huge issue!!! Lack of shifting or hard shifting causes a SUDDEN stop of vehicle with no warning signs while driving!! It is going to cause a crash!!!! These are serious and dangerous issues that Gm will NOT do a recall for!! GM is aware of the issues due to Suburban, Tahoe and Silverado vehicles in the year models 2018-2023 having this reoccurring issue!!! I recall needs to be done to save someone’s life!!!!! I have only had my suburban for 8 months!! I was not made aware of this issue at all!!!!!! This also causes rough idle!!!!!!!!

Wheels 22" Chrome upgrade from the standard wheels from the factory The tire bead where the chrome meets the interior alloy metal corrodes. Thetires start losing air pressure. The tires should be 35 PSI. The front tire dropped to 23 PSI making sterring pull to the right. This is a problem with all 4 tires on the 2018 Chev Suburban Premier. I need to check tire pressure weekly

No official incident has happened yet, but the brake assist kicks in, yet does not work until it's revving engine to over 4000rpm, which causes a sudden jerk and scary sounds from engine. I have had a few instances where the vehicle did not want to stop almost causing an accident, and these have happened without anything in the car other than my daughter who is 2 and myself. The most recent problem is a weird rattling sound while going uphill. Before this going uphill is extremely sluggish, where I have the gas peddle almost to the floor, but nothing happens other than decrease in speed until it finally, about 30 seconds-1 minute, where it kicks into overdrive. Even then, speed does not increase by more than 5-10 mph depending on the incline. I have not brought it to get looked at yet, as I've seen these issues have been reported by numerous consumers without any recalls being sent out other than the breaking system update.

My vehicle completely shuts off while driving. All of the components on the dash and even my steering wheel moves into the prestarted vehicle position. It has happened 3 times in the past week now. One particular instance, I was on the highway and thankfully it came back on immediately before completely stopping but shutting off while driving 65mph is so dangerous.

Dear NHTSA, I am submitting this complaint to report a recurring and potentially dangerous issue with the transmission in my 2018 Chevrolet Suburban, which I purchased brand new in 2018. At approximately 60,000 miles, I experienced severe transmission issues that led to a complete transmission replacement. Now, at around 133,000 miles, I am encountering the same symptoms once again. The transmission makes a loud clunking noise during acceleration and braking, and shifts gears abruptly and harshly. These symptoms appeared suddenly, with no warning lights or prior alerts. This problem poses a significant safety concern. The vehicle sometimes struggles to accelerate properly, making it dangerous to merge into traffic. Additionally, the forceful shifting makes the vehicle feel unstable and unpredictable, as though something beneath the car might fail while in motion. I transport my husband and our children in this vehicle, and this issue puts all of us at serious risk. I have scheduled another appointment with a GM dealership to inspect the vehicle. However, given that this is a recurring failure involving a critical system, I am requesting that NHTSA investigate this matter as a potential defect affecting other owners of the same model. Thank you for your attention to this serious concern.

My Suburban is having the same issues as the most recent recall on the 2021-2025 Chevrolets. The issue is with pretty much all of the motors that go from the V8 to the 4 cylinders. It's doing the same exact thing a friend of mine's 2019 Tahoe did. It's making a loud knocking/ticking noise. When you first get to going it starts almost sputtering which can cause issues if you're in oncoming traffic trying to cross roads.

The Infotainment center display is black and therefore unable to utilize backup camera. The screen is still sensitive to touch but does not display anything for any function. Primarily a safety risk for backing up a large vehicle.

Currently own a 2018 Chevy Suburban with a lifter issue in the engine. This is a known issue with Chevy as many vehicles have experienced this problem from zero to over 100k miles. Chevy has not issued any help or support with customers with this issue. My vehicle is well maintained I get oil changes frequently and have never not done a required service when needed. When I notice an issue I immediately take it to in Regal Chevy for repairs and no matter what the issue is I get it repaired on the spot. I find it odd that this is a recurring issue and Chevy has done nothing to help support loyal customers.

The contact owns a 2018 Chevrolet Suburban. The contact stated that the instrument cluster failed to function as intended. The instrument panel flickered intermittently and then went black, preventing the contact from safely operating the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 132,000.
