I have a 2021 Chevy Suburban with the L87 6.2L V8 engine. At 7k miles, we have lost propulsion, leaving the car undrivable. resulted in the dealer replacing all 16 lifters under a recognized bulletin. I never received extended 6yr 100k mile powertrain warranty as described in the bulletin. Since then, There have been 3 other issues with loss of propulsion, resulting in replacement of fuel pump modulator. belt pulley system, One of the incidents left us without power or control of our vehicle on the interstate, with no where to pull over or get out of the way of oncoming semi trucks. The last incident again left the vehicle undriveable at 84k miles, with the dealer currently reporting that it is a lifter and cam shaft issue. Resulting in a 10k bill. They state that it is not covered under the recall of these engines because it is the top of the engine versus the bottom. Clearly, the engine oil problem noted in the recall has contributed to these issues . and the crankshaft not syncing properly with the lifters.

Driving vehicle on a highway at 55mph, tried to speed up, no propulsion. Fuel injector went bad.
I was standing at a red light with my foot on the brake and the car went into neutral and stalled. I could not restart the vehicle and had to be towed to the dealership where there confirmed a fuel pump module failure. There were no precipitating factors or warnings. This is extremely dangerous. The car is only 4 years old and many people have reported the same incident online, which often recurs, even after replacing the fuel pump. The dealership has ordered the part however it is on backorder without any estimated ship time. For a vehicle I paid over $70K for, this is concerning and frustrating. There is a known recall for 2021 Suburbans for this exact issue.

Hi, my name is [XXX] . I have two major issues with my 2021 Chevrolet Suburban: The value body failed for the 2021 Suburban in December, causing engine power reduction and the engine transmission was not shifting properly. This was covered by my extended warranty, which I paid $2500 extra for at the time of purchase. Also, this VIN is for a Chevy Suburban Duramax Diesel. The Emissions Control Module ( ECM ) light has come on several times, starting from about 20K miles to now 61K miles. I noticed the ECM light comes on at about a 8K mile interval. I take it into the dealership and they have told me this is due to a software issue and then they reset the light. This has happened on at least 4 occasions since about 20K miles. However, now at 61K miles, they are telling me that the exhaust system has a leak and it may not be a covered repair under even my extended warranty. Basically, General Motors has kicked the can down the road on the ECM issue until it is no longer under warranty, and now they want me to pay for this expensive repair. This is wrong, I hope you can protect me and other Duramax owners from GM's unscrupulous business practices. You can reach me at [XXX] for more details. Thank you, I am considering legal action against GM for this issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The fuel tank strap bolts became loose and fell out, causing the fuel tank to drop. The vehicle has the original fuel tank and to our understanding, it has never been removed. We purchased the vehicle new and are the only owners.
The fuel pump power control module (p129F, I believe) failed. I was in the carpool line when the engine sputtered then turned off, and would not turn back on. The engine light also came on. I had to walk my children the rest of the way, then got a tow truck. There were no dash light or other indications of a problem ahead of time. My local GM dealership was not able to get to me for multiple days, so I towed the vehicle to an independent mechanic. The mechanic informed me that there was already a recall on this part (Recall number N212332040). I paid for the repair, and when I contacted GM, was told that my VIN was not included in this recall. I would like my VIN added to the recall and other VINs with this same part that were not originally included in the recall.

Vehicle stalled while driving in center lane on I-4 in Orlando in traffic. There were no warnings prior to the vehicle stalling. When trying to restart it, the low fuel warning appeared along with the check engine light. I was unable to restart the vehicle leaving us stranded in the middle lane of I-4 in heavy traffic. FL Road Rangers arrived to offer aid and had to manually place the vehicle in Neutral under the vehicle at the transmission. Vehicle was then pushed off the highway onto the shoulder. Vehicle was towed to Starling Chevrolet which was the closest Chevrolet dealer from the incident. Starling's Service Department had to replace the battery in order to run a diagnostic. Once the battery was replace, the diagnostic indicated that the issue is with the Fuel Pump Power Control Module Part No. 13544060 / 13554821. This part is on back order with no known availability time provided. Vehicle is still sitting at Starling Chevrolet. Although my vehicle does not show any open recalls, I found that the fuel pump power control module for the 2021 Chevrolet Suburban is part of a known Product Safety Recall N212332040 Stall While Driving.
The fuel pump power control module caused the fuel pump to fail and resulted in unexpected engine stall. The issue cause me and my 4 children to be stuck in the middle of the road waiting for a tow truck for over 3 hours. The vehicle could only be put in neutral while the car was on. Since I couldn’t start my car I could not put it in neutral to move the vehicle out of 2 way traffic. We want the issue confirmed by the dealership but the police who aided me and my children inspected the vehicle and recommend getting the fuel pump look at. No warnings were displayed.
Fuel pump incident identified in recall N212332040. the federal safety agency says our 2021 Suburban was not involved in the recall. But the incident happened 3 separate times. Our dealer made the repair under warranty.
While driving on the I-4 interstate on Saturday August 5, 2023 - my 2021 Cheverolet Surburban stalled as if it had no fuel (had 3/4 of a tank). I was barely able to get over to the shoulder across three lanes of traffic on an overpass before it completely shut off! The Surburban would not start - when pressing the start button the ignition clicked for an extended period of time. We used On Star to contact GM/Chevy roadside support. They ran a remote diagnostic stating an issue with the Fuel Management System. I was told that this is a common problem with the fuel pump failure. I see there are open recalls for many other GM vehicles but not for my VIN currently. My Surburban has 40,669 miles. We waited over 3 hours for the tow truck that was dispatched by GM/Chevy. We were not in a safe location. Turns out my Surburban cannot be placed in neutral without the vehicle being started, which means it had to be dragged on and off the tow bed. I had to pay $450 to have it towed to my my home town dealer as we were 90 miles from home. We were originally going to tow it to a local dealer when the Surburban stalled but they told me not to as they are backed up and could even look at it for 9 days. I am now waiting on word from my dealer. Clearly the recall needs to be expanded based upon what we are finding online and from what everyone is telling us locally.

On 27 Feb 2023 the vehicle started as usual. After parking and letting the engine idle while I assisted my elderly mother into the car, the vehicle unexpectedly stopped running. Several attempts were made to restart the car, but it only sputtered for a few seconds as if it were out of fuel. I then called GM roadside assistance and the vehicle was towed to Sandy Sansing Southern Chevrolet in Foley Alabama. My service Advisor Ronny advised me that this was a common failure of the Fuel Pump Power Control Module, however, there is no current recall. Except I did find a recall for a similar issue for other GM vehicles (Product Safety Recall N212332040 Stall While Driving) The dealership currently has 25 other vehicles awaiting a new module which could take up to 2 months.
My vehicle died unexpectedly in the middle of the road while backing out of my driveway with cars coming and going around me. It would not start up again nor could I put it in neutral to move it out of the way. I’ve learned my 2021 Suburban has a defective high pressure fuel modular. Also learned there is a parts shortage as well.
