2023 Chevrolet Suburban Problems

6.2 V8 while operating threw multiple error codes, went into crawl mode unexpectedly.

The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving approximately 65 MPH, the transmission erroneously shifted to neutral(N), and the vehicle decelerated unexpectedly. The vehicle was pulled off the freeway and parked on the shoulder of the road, and the police were contacted and arrived at the scene and assisted with removing the small children from the vehicle. The vehicle was later towed to a nearby towing lot. The contact later received messages on the App for transmission and engine failures. The cause of the failures was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The contact stated that the vehicle was previously serviced under the NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); even though the vehicle had experienced the failure listed in the recall. The failure mileage was 25,300.

The engine of this car has been under recall for multiple issues during the time we have owned it. The most recent issue that was experienced was total engine failure and electrical malfunction while driving on a busy street near train tracks. The vehicle was making a loud banging sound moments before this occurred. I wasn't even given time to get to a safe spot to investigate the issue. When it shut down, a quick message flashed across the dash board--stating ability to shift had been lost (or something to that effect)--the vehicle then flipped into neutral and immediately lost power. My safety was put at great risk due to the fact that the entire vehicle shut down moments after I crossed over a very busy railway track. The vehicle had to be towed to a nearby Chevrolet dealership where it has been confirmed there was total engine failure as well as blown main electrical fuse.

The vehicle was shaking and shuddering when trying to maintain highway speeds. Would have to slow down to maintain safety. The dealership advised the transmission needs replaced however we are seeing this is a widespread problem that GM has refused to admit fault for.

Transmission malfunction. This has appeared several times at highway speeds and low speeds. Driver to limp along in the slow lane to exit ramp and take back roads to get back to base. The current problem has been confirmed with error codes P0747. Check engine light comes on with a screen prompt “Reduced Acceleration Drive with Care”.

The fuel pump module on this vechicle failed, and there's a recall for 2021 I believe other years should be considered as well since this was a known issue as soon as we arrived at the dealership and they wanted over $400 to replace this part which is only $45.

My 2023 Chevrolet Suburban Premier is covered under GM recall 25V-274 for the 6.2L L87 engine defect (loss of propulsion from connecting rod and crankshaft failure). In XXX, the dealer notified me my vehicle required a full engine replacement under this recall. Wareing Sheridan Chevrolet in [XXX] replaced the engine, and the vehicle was out of service approximately 12 to 14 days. Approximately 6,000 miles later, on XXX, the replacement engine failed while I was driving on the interstate highway near Billings, Montana. There were no warning indicators of any kind until I suddenly lost power. Only at the moment power was lost did the check engine light come on and a low oil pressure warning appear. I was barely able to get the vehicle off the interstate before it died. I had my family in the vehicle, and losing power on the interstate with no warning created a serious risk of a crash. The vehicle had to be towed to Denny Menholt Chevrolet in Billings, MT. On June 13, 2026, the dealer confirmed the vehicle needs a second complete engine replacement under the same recall. This is the second L87 engine failure and second full engine replacement on this vehicle under recall 25V-274. No crash or injuries occurred. I have an open case with GM (#XXX).

My 2023 Chevy Sububan Z71 wipers sometimes does not working when I driving on raining days since I bought it new and took it to dealers many times can not fix it

Automatic Emergency Braking system activated at ~77mph. Essentially I had started braking appropriately and at about the same time the AEB system seemed to conclude more breaking was needed. This led to brief loss of vehicle control when brakes COMPLETELY LOCKED at high rate of speed ~77mph. According to vehicle manual this system should not activate at speed great than 50mph (photo attached). This is dangerous because i could have lost control and/or someone behind me could smash into me. My vehicle does not have adaptive cruise. Vehicle and other systems otherwise work perfectly. As a side note the extreme brake application at high speed caused cargo within the vehicle to slam forward and destroy the windshield, in addition to being a scary event.

Vehicle mileage is approximately 45,000 miles. While driving in the rain the front windshield wipers stopped moving and were stuck in the down position. They would not activated with auto, manual, or wash commands. Rear wiper still functioned. This happened while driving down the interstate which resulted in having to slow my speed in heavy traffic and go out of driver position to see through a clear spot in the windshield, took exit 1 mile later and tried to find gas station, approximately 1 mile after exiting the wipers started to work again. This also happened at approximately 35,000 miles on the vehicle and the wipers did not work for multiple days, even with vehicle turned off for 12 hr period. Took to dealership and by that time they were working again and the dealership could not find anything wrong. Both instances happened on weekends so could not take directly to dealership while issue was present.

Sun Roof has leaked. The Sun roof leaked a considerable amount of water and it came through the head liner around the ceiling mounted control panel as well as the back of the car. This is the second time it has happened and I have been told it is not covered under warranty. Through online blogs and forums I have found that this is a common issue with 2021 and newer tahoes and suburbans. And that is a reoccurring problem that is commonly not fixed properly by the dealers This causes a safety and health issue as well as an unacceptable vehicle defect. 1.) From a safety standpoint, if I am driving down the highway and a large amount of water starts pouring out of the headliner on the driver it causes a major distraction that could lead to high speed accident. 2.) From a health issue, regular water leaks could lead to vehicle mold and water damage. I have children, if they become susceptible to the mold it could cause health issues for me or my children. 3.) The water that pours out of the ceiling lands on the dash electronics which could lead to more vehicle issues by damaging electronic controls. It is my opinion that this is a major vehicle defect and something should be done by the manufacturer to correct it. I have made a complaint to the Chevy Customer service under reference #890 780 85

The sunroof drains continue to fail. I’ve had multiple occasions where the car has had drains back up or be disconnected.. This is a safety issue because it creates mold as water falls in the headliner and then the cabin. It also creates rust, particularly behind the dashboard. That’s not rust proof. Despite being under warranty, the dealers are useless and helping address the issue because it’s la design flaw. The multiple water intrusions also affect the electronics in the vehicle., potentially disabling critical features like airbags and safety systems.

Sun roof exploded while driving. Temps were not extreme, there were no significant pressure changes. Sun roof had no prior damage. Looking online multiple people reported the sun roof exploding on 2023 tahoes and suburbans.

I was driving to work last Wednesday, and I live on a hill. As I was driving, a "Brake failure" alert came over my dash and I lost all control of my brakes!!! I live right off of Main Street, and my options were only to go straight and into a house, or to turn onto Main Street and hope no one hits me or that I don't hit another vehicle. I turned and thankfully no one was coming. At the end of that street I was able to coast into an closed down gas station and park the vehicle. I called the dealership I had purchased this vehicle from 10 months prior, and they told me I had to use OnStar to have it towed to them. I did that, and they towed it to the dealership. The next day the dealership told me the cause of losing my brakes was due to a SOFTWARE UPDATE that was needed!!!!! They charged me $800 for the update & a battery that they said was not holding the charge, which I've never had an issue with. I had purchased an extended warranty with this vehicle and I was told it would be a bumper to bumper warranty AS IF I had purchased it new (it was 2 years old). The dealership said this was not a critical software update and was not covered under any warranty. I could have been KILLED or seriously injured or killed or hurt someone else due to my brakes going out due to a SOFTWARE UPDATE that was needed!! This is insane!

The drivers side, female end, of the seatbelt comes undone when cold. This is reproduced every single time it is cold for approximately 5 minutes of driving until the inside of the vehicle warms up. This happens with both primary divers of the vehicle. We took it to the dealership we bought it from but because there is not a current recall and they cannot reproduce the issue since our current temperature is in the 40s, they won’t replace it under warranty. No warning systems go on when this happens while driving.

The vehicle was purchased brand new from the manufacturer. Because the third-row seating was rarely used, it was not immediately apparent that the car was delivered without one of the required seatbelts. Once the issue was discovered, it was promptly reported to the manufacturer. However, the customer service representative refused to address the problem, stating that the warranty period had expired. This is a serious safety hazard. A missing seatbelt poses a significant risk of severe injury or death in the event of an accident, and it requires immediate corrective action.

The lights flash high beam, low beam, high beam, low beam, while I’m driving. Nothing seems to keep them from doing that.

While driving on the highway at night during rainy conditions the wipers stopped in the up position, and at the same time, the headlights turned off. After a few seconds they resumed normal operation. My headlights were in the auto position and my wipers were also in the automatic setting. Being as that I was on a highway at night, in the rain, and going approximately 65mph surrounded by traffic, this was an extremely dangerous situation to be in. Without headlights and windshield wipers, my windshield was immediately obstructed and I was unable to see the road without headlights. More so, other traffic might have had trouble seeing my vehicle. This problem has not been replicated by myself or a dealer. It has been random in nature. When the incident happened, there were no warning lights on the gauge cluster or anything else inside the vehicle that seemed to be affected.

My vehicle was met with an accident on June 28, 2026. The accident was very swear and driver get internal injuries like swelling on face pain in head and ribs due to the heavy shock. But non of the airbag has been activated for safety of driver.

Vehicle was purchased new, has 2900 miles on it. The service safety restraint system light came on. I know this has been on going issue in past on these vehicles and want it reported and documented.

The contact owns a 2023 Chevrolet Suburban. The contact stated that the front passenger’s and rear driver’s side rims were cracked. The front passenger’s side rim was replaced by the dealer under warranty, while the rear driver’s side rim was replaced with an aftermarket part. The manufacturer was notified of the failures but declined assistance. The owner expressed concerns that the remaining factory rims might also crack and were prone to failure while driving. The failure mileage was approximately 100,000.

Transmission valve control failed. Rear wheels locked up. Vehicle downshifted quickly. No injuries. Vehicle is at dealership for repairs. No warnings.

I brought my Chevrolet Suburban High Country in to the dealer pursuant to a recall for engine issues due to a manufacturing defect in connecting rods and crankshafts that can cause catastrophic engine failure. The service center changed the oil viscosity and fill cap and stated that the change should eliminate the issue. I have had persistent engine knocking upon acceleration since then and it is getting louder and more prominent. A suspension warning intermittently flashes as well. Please advise, thank you

Vehicle had 14,000 miles and tires were rotated by dealership twice, last one 3 weeks ago. Was driving 55 mph and had a sudden complete deflation and stopped immediately. Tire is completely separated. The outer sidewall is completely separated from the rest of the tire. The tire has never had an injury or other issues. The tire rotation was at Gerry Lane Chevrolet in Baton Rouge, LA. I took the tire in the same day to Gerry Lane Chevrolet service department and they were not helpful. They did not even look at the tire. I am having all 4 tires replaced tomorrow at Costco and will keep the damaged tire and 3 others for any forensic evaluation by your department or designate. I am concerned that this maybe the canary in the coal mine and if there is a manufacturing defect other lives may be at risk. Look forward to urgent follow up. Continental tire has had similar problems with sudden blowouts. 14000 miles properly maintained.
