Other Fuel System Problems of Chevrolet Suburban - part 2

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).

Wife is rn at a trauma hospital going to work in the morning on a busy highway. While in front of hospital truck started to indicate to hit starter button. Truck was already running! wife stopped at red light. Truck stopped running would not start. Stuck in middle of morning rush hour traffic had to have truck towed to dealership. At the dealership they indicated they found metal parts in the oil pan. They indicated a further look into the engine indicated it was beyond repair and had to be replaced. Truck only had 42k miles on it. They stated they had another one same situation in the shop as well and that it would take several weeks to repair. I have learned that this is a major problem with this make and model and engine. Engine quit with no warning in middle of major highway. Thank god not in an intersection or freeway.

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.

The fitting on the fuel pressure regulator on the engine began to separate from the housing and started spraying fuel all over the firewall and the fuel ran down the firewall onto the exhaust pipes. No check engine light signaled. The only way I knew that it was spraying, was I started to smell raw fuel through the air conditioning vents. Luckily I was able to get it to a dealer before any fuel caught fire. The dealer repaired it but gm stuck me with half of the bill for the repair. I have pictures of the failed part if necessary. This is extremely dangerous to anyone that may not pay attention to car issues unless a check engine light comes on.

The active fuel management valves in cylinder 1,4,6&8 failed prematurely.

Car jerks with initial acceleration.

Fuel pump modulator, which has a recall for other vehicles for same part, malfunctioned which caused the vehicle to cut off while my son was driving on the highway without notice, where he had to avoid being hit while trying to make it to the shoulder for safety. The fuel pump module was tested by a service mechanic and was found to have corroded due to moisture. Prior to vehicle cutting off, there were no warning signals/signs, it just cut the vehicle off while driving on the highway.

Started car, noticed check engine light on and rough idle. Car barely would go in reverse to exit parking spot, so I attempted to pull back in. Car would not move forward. Able to switch to neutral and push back into spot. Could have been a very dangerous situation if it had occurred while driving or with my children in tow. Car would not restart at that point. Failed fuel pump @ 50,000 miles.

Def sensor has failed and required placement. Required three visits to the dealer to get them to address it (grayling, mi, white lake, mi and charlottesville va). Transmission throttle body failed and required replacement. Took 2 visits to get it addressed.

High pressure pump failed at 73000 miles.

Fuel injectors are malfunctioning. Engine light has come on multiple times flashing and goes off. Took it to ernie lee's service center & told fuel injectors are not functioning properly. I will be glad to allow it to be inspected upon request because they all need to be replaced & told there's a bulletin out but universal Chevrolet told me it excludes 2017 Suburbans. . It started around 100,000 miles & I only have 125,000 miles on it.

Fuel injector failed and pumped too much gas into cylinder causing gas to get into engine oil and ruin engine. Gm claims they are building the replacement engine, but won't give any estimate of when it will be fixed. Other dealers that are receiving these engines will not sell the engine to my dealer. I believe there is a bigger problem that gm will not admit to and they should be held accountable. Four months is too long for this situation to exist!.

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. Nhtsa 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.

Stopped at a stop sign. The vehicle suddenly lost all electrical power. Lights began flashing. Traction control system turned off and on. Then it went back to normal driving. I just had the chassis control module recall taken care of as well. The air conditioning is intermittently cutting its ability to cool then suddenly cooling again during this time. When the vehicle turned back on, the strong odor of fuel was present from the air vents. I had reported the issue before but was told by a dealer there is nothing wrong they could see beyond a visual inspection.

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.

My wife called me and said she could smell gasoline in our 2015 Suburban. I went to the store she was located at and it smelled like raw gasoline. I called a tow truck company and to haul our Suburban to the shop. The fuel line has been rubbing against the vehicle frame and rubbed a hole in it. This is very dangerous as the fuel take and line is located right underneath my kids seats.

When I started up the vehicle with the key fab button I noticed the cabin air blower came on as normal however when we went to the cockpit we noticed the engine was not running. When we went to start the vehicle (holding break and pressing start button) the dashboard started the z71 launch sequence and then went to a dashboard as if I was in the normal drive mode however the dashboard was extremely dimly lit as if the backlight was not on and the engine still was not running. After several attempts to start using the brake+start button method we noticed a clicking sound that seemed to be coming from the engine cabin just in front of the passenger cabin however it would never ignite/start the engine. After several attempts to start the engine through the brake+button, we tried to just press the start button, which would sometimes be prompted on the dashboard, and get some feedback from the dashboard through better backlighting and messages I now cannot recall but never ignited the engine. When we tried again with the key fab x2 button (hoping it would either start or "cancel" the current vehicle state), we received no response from the vehicle. When we attempted to shift, it stated the "conditions were not met", which I perceived as the correct response. The vehicle was stuck in this "mode" with the air blower still running and exterior lights still on and it was only a matter of time until the battery ran out. When it ran out later that day (though not completely ded) in rebooted in the same tweener mode. However, when we came the next day with a tow truck and a fully dead battery in the Suburban, the vehicle booted right up as normal. The tow truck driver indicated several new tahoe drivers experiencing the same issue. To me, this is a software launch issue. While the vehicle was not perceived to be in danger, it left us stranded in what could be a dangerous location. Several episodes as reported by tow truck. Unsure if inspected. No symptoms before problem.

When pumping fuel the gas is bubbling up and pouring back out of the tank when it isn't full.

Leaking fuel line from pump to engine. Rubbed on frame and wore a hole in it.

We smelled gas inside and outside of the car. Upon inspection, I found gas leaking from the fuel line under the vehicle that comes from the fuel tank. This created a dangerous situation as noxious fumes were introduced to the cabin of the vehicle, and the leaking gas created a fire hazard. We took the vehicle to the dealer, and they confirmed that the frame rubbing on the fuel line created a dangerous leak. They confirmed this is a common problem for this model and a redesign of the replacement fuel line would prevent the problem in the future, but no recall has been issued. We paid $1180. 20 to have the fuel line replaced. No inspections other than the dealer and myself have been performed. No warning lights or messages indicated the problem.

While driving, I noticed a significant smell of gas coming from my 2015 Chevrolet Suburban. When I stopped the vehicle, it was even more noticeable. I pulled over and got out of the car only to notice gas pouring (not dripping, more gushing) from under the vehicle between the driver's side door and driver's side passenger door. I was concerned as I had my young child with me and had no way of having someone pick us up. I drove it directly to the mechanic in which they confirmed a leak coming from above the tank and that they would not be able to repair the leak until they dropped the tank. Once dropping the tank, they found a hole in the fuel supply line above the tank due to a poor design and friction from the poor design. There is a service bulletin, 17-na-304, but it does not protect owners from the cost of the repair. The repair cost was $425. 38 despite it being a known issue with gm. This design is incredibly dangerous. Not only is the raw fuel inhalation through the vents a health hazard, it could cause a catastrophic fire as well. I have four children, the reason why we needed to drive a Suburban. The devastation of the risk of this flaw is incredible. This needs to be considered a recall and the cost should be covered by the company, not the owner. I emailed gm's customer service and they stated that nothing could be done because the vehicle was out of warranty.

Fuel line running from fuel pump to engine rubs on the frame causing a leak in the fuel line.

The break vacuum pump is going out and making vehicle hard to stop and fuel pump or vacuum is leaking gas and smell inside vehicle.

Have had starter problems since we purchased the vehicle. Starter intermittently loudly grinds when pressed 2-3 times a week and won’t start. Dealership could repeat problem once, but never fixed it. Took vehicle in at least half a dozen times. Never fixed. Car also makes an odd humming when gas is applied. This week, car started and died after driving a foot. Then car wouldn’t start at all. Brakes stiffened up and wouldn’t compress without substantial effort. Everything resolved on its own within 30 minutes. But the very next day, pulled inti position in our alley to back our Suburban into the garage. Put car in reverse. While using the back up cam (that came on like normal when car is in reverse), I applied gas. The car didn’t respond at all (didn’t even rev like what happens when you apply gas while car is in neutral). I applied a touch more gas and car all of a sudden lurched forward with the full force of a v8 engine being floored. I tried to slam on the brakes, but the brakes wouldn’t respond in such a way that I thought my shoe must have gotten stuck. It hadn’t. The brakes did not work. I don’t know how long it would have taken to finally stop because we only had 5 feet to go before we slammed into our neighbor’s house (which is what stopped our vehicle). Car is not drivable and I wouldn’t drive it if it were. It is available for inspection. Will be towed once scheduled.

Due to a faulty design, the fuel feed line (gm part # 84200271) has been worn through from vibration resulting in a pin hole in the line at the point where the fuel line is seated in the molded-in clip retainer of the fuel tank. This wear has resulted in raw fuel pouring over the top of the fuel tank and producing a significant risk to life and health from fire and inhalation. The fumes from the raw fuel could be smelled through the a/c vents while driving highway speed (inhalation hazard). Once the vehicle is turned off the fuel leak subsides. However, while idling in park the fuel leak would puddle under the vehicle resulting in a significant and potentially catastrophic fire hazard. While researching the symptoms of my issue, I discovered many complaints of the exact symptoms and findings that I have discovered. I spoke over the phone with a service department employee of a local gm dealership who denied having addressed this issue on other vehicles similar to mine (2015 Suburban lt). I will bring the worn-through fuel feed line to this same dealership to inquire about possible mitigation for this known issue (see service bulletin 17-na-304). The symptoms that I first noticed were a hard start and the smell of raw fuel in and around the vehicle. No check engine light or other warning messages were displayed to alert me of this failure.

We had just completed a 1,000 mile trip for a family emergency. When we arrived at our destination, we found that somewhere during the last 500 miles of the trip, we had developed a fuel leak. After removing the fuel tank, my husband discovered a break in the fuel feed hose, as well as several worn spots in the line and on the top of the fuel tank. We were traveling in 100 degree weather, and I am just thankful at this point that the Suburban did not catch on fire!.

We experienced a massive fuel leak from the top of the fuel tank. The car was still able to run, but there was fuel draining all over the place around the bottom of the car. My wife drove the car with our four kids in it for about 50 miles before we knew what was going on.

I purchased this vehicle in Dec of 2019 used. 35,000 miles. Now has 88,000 and the transmission went out. Regular oil changes. No warning lights. No issues. Stopped running. After having someone look at it to see what the issue was, the mechanic said the entire transmission has to either be rebuilt or replaced.
