2019 Chevrolet Suburban

I was driving yesterday when my car began to shake at low RPMs. The traction control light came on steadily and the check engine light was blinking. I was unable to safely accelerate. I took it to my mechanic who tested spark plugs and coils, which he confirmed aren't the problem. He informed me that this is a common issue with the GM 6.2L engine, but mine isn't part of the recall. After checking online I see that this is exactly what many others are reporting and that there's an NHTSA investigation as well as a class action lawsuit tied to this issue.

The contact owns a 2019 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the vehicle slowed down and failed to properly shift gears. The contact shifted into neutral while stopping the vehicle. Additionally, the contact stated that the vehicle failed to accelerate as needed. The vehicle was driven to a dealer, where it was diagnosed with severe fluid leakage and torque converter shutter. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 112,000.

Two years ago, we had to have the transmission rebuilt after it kept slipping. Yesterday, as I was driving on I-95, I was passing a vehicle and pressed on the gas. There was a loud crunching noise and I lost acceleration. The check engine light came on right away and I couldn’t press on the gas without a noise and limited forward momentum. I then had to maneuver the car across four lanes of traffic with limited control over speed. There was no warnings an issue was going to occur. We had it towed to our mechanic who said there was low compression in cylinder 1. Less than 90 psi. Again, we had already had the transmission replaced and now this major engine issue. We are in the process of getting it to a Chevy dealer.

Year: 2019 Make: GMC Model: Suburban Mileage: Approximately 125,000 miles (purchased under 90,000 miles) 1. Transmission Failure My vehicle is experiencing clear signs of transmission failure, including: •Hard downshifting/clunking •RPM fluctuations while cruising •Shuddering between approximately 30–50 mph •Vibrations while idling •Hesitation and irregular shifting These symptoms have progressively worsened and are consistent with widespread complaints I have found from other 2019 Suburban owners. This appears to be a known issue affecting multiple vehicles. 2. Rear Liftgate / Electrical Malfunction The rear trunk/liftgate has closed on its own without warning multiple times. I have personally been struck in the head several times as a result. This presents a serious injury risk, especially for families loading children or cargo. There is clearly an electrical or sensor malfunction causing this behavior. 3. Automatic Emergency Braking (AEB) System Activating Randomly The most alarming issue is that the automatic emergency braking system has activated on its own multiple times while driving on the turnpike with no obstruction present. This has nearly caused accidents on several occasions. Unexpected braking at highway speeds creates an extremely dangerous situation for both my family and surrounding drivers. These issues are not minor inconveniences — they are serious safety hazards. Sudden braking, unintended liftgate closure, and transmission failure all create significant risk of injury or collision. Given the number of similar complaints publicly reported by other owners, I am requesting that NHTSA formally investigate these defects and determine whether a recall should be issued for affected 2019 GMC Suburban vehicles. I am extremely concerned for the safety of my family and others on the road. Please confirm receipt of this complaint and advise if additional information is needed. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)

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 contact owns a 2019 Chevrolet Suburban. The contact stated that while stopped at a traffic light, the vehicle failed to accelerate as intended while depressing the accelerator pedal. 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. The vehicle was then towed to the dealer, where it was diagnosed, and it was determined that the transmission had failed and needed to be replaced. The contact stated that, as per the two truck drivers, transmission fluid was leaking onto the street. The vehicle remained at the dealer unrepaired due to the cost. The manufacturer was notified of the failure. The failure mileage was approximately 95,000.

The contact owns a 2019 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, a loud knocking sound was heard coming from the engine compartment. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the rod bearings had failed due to a large amount of copper found in the engine oil. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The dealer was contacted, but had not diagnosed or repaired the vehicle. The manufacturer was not made aware of the failure. The approximate failure mileage was 113,000.

Major engine failure in my 2019 Chevrolet Suburban Premier equipped with the 6.2L V8 engine (L87). Despite routine maintenance and responsible operation, the engine recently suffered a serious failure that has rendered the vehicle inoperable. After researching the issue and speaking with several service professionals, it appears this type of engine failure may not be isolated, but part of a broader pattern affecting similar models. Given the vehicle's relatively low age and the severity of the problem, I believe this may be indicative of a manufacturing defect or premature engine wear that should not occur under normal operating conditions.

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!!

The contact owns a 2019 Chevrolet Suburban. The contact stated that while driving at various speeds, the vehicle hesitated upon depression of the accelerator pedal and made an abnormal whining sound. The contact stated that the check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the torque converter had fractured, and further diagnostic testing was needed. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 130,000.

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.

Lifter stuck in cylinder 3. Cost to repair $13,000 on a 2019 Chevrolet Suburban with 101,000 miles. We have owned vehicle since new. Vehicle routinely maintained.

The contact owns a 2019 Chevrolet Suburban. The contact stated that there was a winding sound coming from underneath the body of the vehicle in the center of the cabin. 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.

Statement of Incident and Repair Costs While driving on the expressway at approximately 70 mph in the express lane with my family in the vehicle, the engine suddenly began to stutter and run rough. Within seconds, the vehicle lost engine power, the oil light came on, and the check-engine light started flashing. The sudden loss of power caused another vehicle to almost collide with us from behind, narrowly missing my family when our truck slowed abruptly. Because of the immediate danger, we were forced to cross two lanes of interstate traffic to reach the shoulder as quickly as possible, putting my entire family at further risk. We were then stranded on the side of the expressway. The vehicle was taken to the Chevy dealership in DeMotte, Indiana. Their diagnosis determined a catastrophic engine failure caused by lifter failure, resulting in bent rods and damage to the camshaft. Despite widespread reports and known issues involving lifter failures in this model, there is no recall for this year and model. As a result, we were left to cover the full cost of the repair. The dealership did not provide a rental vehicle, even though this truck is our family’s only means of transportation large enough to safely haul all of us. Insurance would not cover the failure due to the numerous notices and documentation showing that GM/Chevy is aware of this problem but has not initiated a recall. Total cost of repair: $8,801.53, paid out of pocket. Of which we had to borrow and scrape to figure out how to pay for it, due to it being our only vehicle for our family. Now we are left with the uncertainty as to whether the same thing will happen again, endangering the lives of our family yet again, due to living out more in the country and having to drive 30+ miles one way to get to grocery stores etc… on roads that have a speed limit of 55mph rt 49 going north from south of the Kankakee river or the expressway again where the other incident occurred I65 by Lowell Indiana exit.

I have a 6.2 v8 engine and the transmission failed and is not currently covered under the class action lawsuit!

The contact owns a 2019 Chevrolet Suburban. The contact stated while stopped, the vehicle was slow to accelerate. The contact stated that the vehicle was shuddering while driving at undisclosed speeds. Additionally, the contact stated that the vehicle was hard to start. While the vehicle was in the driveway, the vehicle failed to start. There were no warning lights illuminated. The vehicle was towed to a transmission shop, and it was determined that the failure was due to the transmission. The vehicle was repaired, but the failure recurred. While her husband was driving at undisclosed speeds, the vehicle hesitated while in third gear. The contact stated that while her husband was driving, the vehicle was shifting hard. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, who confirmed there was no recall and opened a case. The failure mileage was unknown.

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.

My engine had a defect which required the entire engine to be rebuilt. The engine lifters, push rod and crankshaft all failed and I had to incur a $9000 repair. I believe this is in line with the current recall of Chevy 6.2L V8 engines like mine. I believe this is defect of Chevy's that they should be required to reimburse.

Engine failure due to bearing wear per independent service center diagnostic. States that engine needs to be rebuilt or replaced. There was no forewarning of this engine failure. I believe this issue is subject to ongoing investigation PE25001.

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