The suburban pulls to side. I got it into the service center and they tried to fix the alignment but when we got it back it still does it. So im not driving it til it gets a second opinion because its definitely not the alignment if it is still doing it. So I dont feel safe driving it with me or especially my kids in it.

The check engine warning light and traction control warning light were illuminated. The contact pulled over to the side of the road. The contact continued to drive the vehicle; however, the vehicle hesitated to accelerate as intended. The contact was able to drive to the residence.

Transmission started shifting very hard while in motion. The vehicle shudders while at speed. Extremely loud vibrations coming from under the vehicle. This vehicle only has 75 k miles on it. Mechanic first flushed and changed transmission fluid. Vehicle still shifting and running rough. Mechanic says we have to replace the entire transmission. Vehicle has always had top routine maintenance done. This suburban is too new to require a new transmission. Chevrolet needs to recall this issue and replace at their cost! Lost power while on interstate at 65 MPH. Extremely unsafe!!

I have a 2019 Chevy Suburban 5.3L, 6-speed autimatic transmission. I recently started having real bad hesitation while in any gear and can feel it going into any gear real bad. Was quoted filter, fluid and gasket replacement. I had that work done at $459, which didn't fix the problem. Then they said, "it's possibly the clutch." Apparently after talking to a mechanic (who also has the same transmission with problems) and reading reading online, there are a bunch of people having problems with this transmission. This vehicle is only 6 yrs old, it shouldn't be having problems like this. GM should do a recall on these transmissions. I'm on a fixed income and don't have money to get it fixed.

The tow light was intermittently illuminated without the vehicle being placed in tow mode. The contact stated that while accelerating and shifting gear, the vehicle hesitated and was sluggish while accelerating. The vehicle was taken to a certified mechanic who diagnosed that the transmission fluid was black, due to the transmission burning. The mechanic stated that flushing the fluid would cause more issues and advised the contact that the transmission needed to be replaced. The vehicle was not repaired. The vehicle was taken to the dealer; however, the contact was only quoted the cost for the repair because the vehicle was not covered under warranty. The manufacturer was informed of the failure and confirmed that there was no recall on the vehicle. The manufacturer also confirmed that the VIN was outside of the 60,000 miles warranty. The manufacturer opened a case for the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 77,000.

Catastrophic transmission failure while brining my children to school. Mechanics states the clutch pack possibly went bed causing the transmission to fail. Vehicle services appropriately. Chevy warranty refused to help claim.

This vehicle has broken down for times now. The latest is from a failed transmission that needed replaced.

My certified used 2019 Chevy Suburban, with all routine maintenance completed, transmission abruptly failed. The vehicle was just serviced the month prior and with no current issues revealed during that appointment. We have never seen a transmission just fail suddenly with no warnings, no light on dash, and the transmission fluid was a good color and with no burn smells. My wife had just been on the 35 freeway and a moment before exited off to where we were going to eat breakfast, had she still been on the freeway, it could have been catastrophic as she had three of my children in the car with her. I researched the internet; GM has had many transmission problems on Suburban and other model cars from 2015-2019 with their currently being a class action on the other models.

My transmission went out at 116,000 miles. We were having intermittent issues since 100k miles.

Catastrophic transmission failure while driving on highway trip with family. Thankfully did not completely lock up drive train, but such a catastrophic failure could have caused a transmission/engine lock up leading to a serious accident. Drove to nearest Chevy dealer (Everett Chevy Morganton NC), inspected, validated catastrophic transmission failure. Vehicle towed back to Hendrick Chevy Monroe NC. Hendrick confirmed catastrophic transmission failure, required complete transmission replacement. I requested failed part evaluation/warranty review. Escalated to Chevy customer support. Hendrick replaced transmission 1/29/2025. Hendrick upgraded to new Thermal Bypass Valve per service bulletin #21-NA-199 as part of complete transmission replacement. Vehicle was serviced previously on 11/1/2025 for routine oil change and inspection, with transmission noted as "good." Onstar monthly diagnostic for December 26, 2024 indicated engine and transmission system "good/OK".

Car jerking and lurching forward in stop and go traffic. Mechanic confirmed transmission failure.

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission failed due to transmission oil that went bad and subsequently damaged the transmission. The failed transmission is available for inspection upon request. How was your safety or the safety of others put at risk? The transmission failure created unsafe driving conditions by reducing vehicle control, particularly in situations requiring acceleration or deceleration. This could have resulted in a collision if the vehicle lost power while in motion. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the problem has been confirmed by an independent service center, which diagnosed the transmission failure as a result of degraded transmission oil. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. It has only been inspected by an independent service center. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, there were symptoms prior to the failure. These included occasional transmission slipping and delayed gear shifts, which began several months before the complete transmission failure. No warning lamps or dashboard messages appeared. This issue is of significant concern as the vehicle was purchased as a Certified Pre-Owned vehicle in 2022 and the transmission should not have failed this early. I am requesting an investigation into this issue to determine if it warrants a recall to prevent future safety risks for other drivers.

Suburban needs a new transmission with 85,000 miles.

2019 Chevy Suburban Premium at approx 121k miles whole body of vehicle starts shaking & vibrating at 45 mph, behaving like like torque converter going bad. Transmission intermittently acts like its slipping in 2nd & 3rd gear, when it does catch it shifts VERY hard. ..No dash lights. No warnings. Nothing....

transmission is slipping, can’t find replacement anywhere seems that even dealers don’t have replacement parts was told that there are a lot of 2018–2019-2020 that have same problems when i called Chevy they said they are sure there are parts

My transmission is slipping, my neighbor who's a mechanic looked at it and luckily this vehicle has a transmission dipstick, fluid level was still good but we checked the Trans filter and we saw metal bits. We did a transmission fluid change and filter. It's not doing as bad but still will need to get transmission and converter replaced. Talked to a few places and they all say that this transmission always having problems and need replaced. I have supposedly a warranty but fighting with dealership about coverage. The amount of regularly seeing problems with this transmission from repair shops surprised that there isn't a recall. They say they replace the style on my car all the time on gm products supposedly it comes from the Ypsilanti plant in MI.

Transmission was slipping, took to dealership to check, serviced it by changing filter and transmission fluid and gasket. At 80k miles transmission was slipping again and jerking from stopped position. Took back to dealership now they are saying I have metal in fluid and internal transmission failure? Cost to replace $13,000? This car barely gets 10k miles per year and serviced appropriately. Recall on this power train?
