2019 Chevrolet Suburban Engine Problems

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.

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.

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.

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.

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!

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.

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.

Our transmission when out while driving at high speed down the road, which could have caused a serious accident. There was no warning light to alert the driver before this incident occurred. We had to pull over and have our car towed - and it was dangerous to be along side of the road. We had to pay over $4000.00 to have our transmission replaced and the mechanic, who is an independent dealer, said "in his opinion, the transmission problem was caused by the defective GM automatic 8-speed transmission". We have a detailed bill of all work completed by our independent transmission dealer - dated Feb 2025.

At a stop light the stabilitrack and check engine light came on. Engine began running very rough. I pulled around the corner and was able to get into a parking lot. When I stopped the vehicle the car shutoff completely, including all the electrical. I tried to start the car but when I did there was no engagement of the starter and all electrical shut off again. Car was towed to a mechanic shop and was advised that the engine was seized after they could not turn the engine using manual means. I had to have the engine replaced.

The lifters failed in April 2024 and was replaced by the GM dealer and then the engine failed again in September 2024 however I couldn't afford to pay GM $2000 for a diagnostic and they still have my vehicle and only offer me $1500 off of a new or unused vehicle.

The contact owns a 2019 Chevrolet Suburban. The contact stated that while driving at various speeds, the check engine warning light illuminated. The contact took the vehicle to the dealer and was informed that the grille shutter was defective and needed to be replaced. The manufacturer was not notified of the failure. The vehicle was repaired. The failure mileage was approximately 81,000.

While driving the Suburban I am hearing and feeling the transmission slipping and jerking during shifting. Is there a recall on the year / make and model transmission.

The contact called on behalf of his daughter who owns a 2019 Chevrolet Suburban. The contact stated that while his daughter was driving approximately 55 MPH, the vehicle began to shake and lost motive power. The driver pulled over to the side of the road and turned off the vehicle. The contact noticed that the check engine warning light was illuminated. The vehicle was towed to the dealer and the contact was informed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 98,000.

Weld on the radiator failed at 50,000. Dealership said they don't know why but this is common in Chevy Suburbans, GM Yukons, and pickups. From research online I saw that there were repair bulletins for earlier year models. Is the problem continuing? Luckily we were close to home when this failed.
