FUEL/PROPULSION SYSTEM
Check engine light comes on. Car suddenly stalls and engine shutters, shuts off and on. Goes into limp mode as engine shutters at about 15 miles per hour. GM has not included this 2021 Tahoe which is the same exact condition under Product Safety Recall N212332040 "Stall While Driving". That recall was issued at the same time or month as this Tahoe was built and sold and should have been included. This Tahoe was towed to the dealer and GM has not been able to supply parts. The Tahoe will soon have been at the dealer for 60 days with no solution. The recall build dates should be expanded to include all GM vehicles with this defect. It is explained as: "The fuel pump power control modules in these vehicles may contain a supplier manufacturing defect that can cause the fuel pump to fail or operate intermittently, interrupting the flow of fuel to the engine. If the engine does not receive adequate fuel, the vehicle may unexpectedly stall. The driver may see a check engine light, receive an OnStar notification that a Diagnostic Trouble Code has been set, or experience a rough running engine. The vehicle may also be placed into a reduced power mode. A vehicle stall without warning could increase the risk of a crash, especially at high speeds"

UNKNOWN OR OTHER
My vehicle is a 2021 Chevrolet Tahoe with less than 90,000 miles and the catalytic converters have internally failed causing a $3000 complete replacement of that system in which they state should last a lifetime of the vehicle and it is not even five years old.

ENGINE, LANE DEPARTURE: WARNING, POWER TRAIN
While traveling on the highway one day, my 2021 Chevrolet Tahoe began warning lights on the dashboard. Shortly after, it running roughly,, and jerking, so I pulled over to investigate. There no visible smoke, so I drove to the nearest auto parts store, where they ran a diagnostic test that returned a code of P0306. I then took vehicle back to the dealership where have always received oil changes and repairs. I have never visited any other dealership, relying on certified GM/Chevrolet dealerships. After inspecting the vehicle, they informed me that the lifters needed replacement advised that it would be best to replace the engine entirely. Upon further research, I discovered that issue has been affecting many people in our area and across the United States. This needs to be addressed, as the vehicle is only three years old, purchased brand new with zero miles, and I have not done anything out of the ordinary to cause this problem. The vehicle being 70,000 and 12.000 for repairs is insane.

ENGINE AND ENGINE COOLING
The contact owns a 2021 Chevrolet Tahoe. The contact stated while driving 70 MPH, the check engine warning light and other unknown warning lights illuminated. The message "Loss of Oil Pressure" was displayed, and the vehicle made an abnormally loud banging sound. The contact was able to continue driving at slow speeds with the hazard lights engaged. The contact drove to the dealer, where he was employed. The dealer diagnosed that the engine lifters had failed. The vehicle was then towed to the Chevrolet dealer, where it was diagnosed that the lifters had failed. The dealer provided an estimated fee for the repair. The vehicle was towed to Redline Performance LLC, where it was diagnosed that there were metal shavings in the oil pump, camshaft, and in other unknown parts, along with the lifters failure. The mechanic replaced the lifters, the connecting rod, the camshaft, the oil pump, and other unknown parts; however, the failure recurred after picking up and driving the vehicle to the residence. Additionally, there was smoke coming from the engine. The vehicle was towed to Stan McNabb Chevrolet Columbia (101 S James Campbell Blvd, Columbia, TN 38401), who informed the contact that the vehicle would not be diagnosed by the dealer. The contact became aware that the VIN was included in NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), which the contact related to the failure; however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 66,000. VIN tool confirms parts not available.

FUEL/PROPULSION SYSTEM, ENGINE
On May 14, 2023 I was on a trip driving the Tahoe (midnight blue Tahoe in the pictures) about 60 mph, on highway 41 (middle of nowhere, no cell reception) south of kettleman city, CA when, without any warning or symptoms of any problem whatsoever, the engine lost propulsion and died. I was able to coast onto the shoulder and tried starting it. It started again and I continued driving and about 35 minutes later I stopped at a red light on Highway 41 in Lemoore, CA. Again the Tahoe engine died without warning and would not restart. When I tried starting it I could smell a burning smell. The engine cranked but wouldn’t start, and then the check engine light came on. I was at a stoplight on a major highway and was unable to move the vehicle, and was scared to sit in it, so I put on the vehicle hazard lights, got out of the car and ran to the side of the road for safety. Luckily I did not have my children with me. I called 911 and a police officer came and parked behind my vehicle with his lights on so hopefully no other vehicles would hit it. A tow truck was immediately dispatched as high priority by the police. I had it towed to Hedricks Chevrolet dealership in Clovis, California, who informed me there was metal parts in the oil and that the engine was destroyed and had to be replaced. It took several months to get the engine replaced and in the meantime, I bought a new 2023 Cadillac Escalade so I would have a vehicle to drive. The Cadillac Escalade ended up having an extremely similar problem (and I will file a separate report for that vehicle). A few months later when the Tahoe replacement engine was installed I picked up the Tahoe from the dealership and sold it to Carmax.

The contact stated that while her husband was driving at an undisclosed speed, several unknown warning lights illuminated, and the engine made knocking sounds. The message "Service Transmission" was displayed. The contact's husband pulled over and turned off the vehicle. The vehicle failed to restart immediately.

POWER TRAIN
My vehicle has a little over 15000 miles on it. On Thursday April 3rd, while driving 35 mph in town, my RPMs shot up to 4 and the vehicle would not respond to accelleration. A few seconds later the engine light appeared. I managed to get the vehicle home going no faster than 42 mph off and on. Upon arriving home I realized I had no reverse in the vehicle. I immediately called the dealership and was told to bring it in. They didn't look at it until the following Monday April 7th when they determined the Transmission Control Module went out. GM told them they "couldn't find that part anywhere". Thr vehicle still sits behind the dealership and GM has no answers and has already hinted that it may be at least 60 days. This is unacceptable.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS
We had a failed lifter that caused bent rods which caused scratches on the crank shaft which caused us to have to replace the engine. After a simple internet search I have found the lifter failure is very common with gms 5.3 v8. We were told oil needs to be changed at least every 5000 miles although the vehicle prompts you around 7000.

ENGINE
Traction control light came on and the vehicle felt like it was going to die/low idle. I took to dealership on 9/13/22 (5months after getting vehicle) and the codes P03000 00 which is an engine misfire, P050D 00 which is cold start rough idle and it was noted by service tech that engine making a clunk and ticking noise. There was a misfire on cylinder 6. They removed the valve cover and the intake valve rocker arm was not moving at all and when the rocker arm was removed they noticed the push rod was also bent. They verified the DFM lifter was collapsed.

FUEL/PROPULSION SYSTEM
I was driving the vehicle, exiting the parking lot when the engine and all electrical components turned off. This could have easily caused and accident as there were multiple vehicles that had to go around me while I tried to restart the vehicle. The engine would crank but not start up and left me stranded in the middle of the road AND in the middle of two lanes. When I finally got the vehicle towed several days later (which was not easy because in order to put the transmission in neutral without the engine being on, a special tool is needed) I took it to the dealership. They confirmed it was the fuel controller that went bad for the second time. The first time the vehicle was stuck in my garage at home with the same symptoms. They apparently replaced it with another faulty part that is a ticking time bomb. I have no faith that this won't happen again.
