ENGINE
Not sure the exact cause yet. But another big leak of coolant from the car. This is the 4th big problem with the same issue. I have been dealing with engine/radiator/coolant problems with this car since April 2024. It has been in the shop 2 separate times for 9 weeks total. With other visits in between. There is something wrong with this car.

ENGINE
Was driving about 45 mph on 2 lane road. All of a sudden, without warning we lost power (had no propulsion). Luckily there was a residential side street that we were able to turn onto and get off of the highway with no shoulder. We coasted to the side of the street and called a tow truck. Had we not been able to get off the road, we would have been dead in the road, blocking an entire lane of a busy 2 lane highway without a shoulder to pull off on. There was no warning prior to incident but a message did appear during the incident. I believe it said "Loss of propulsion." We turned off the vehicle, then tried to restart it. Engine attempted to restart, but it made a horrible noise & wouldn't restart. Still had battery power. Vehicle was towed to a local dealership where it is currently being evaluated. We know of a massive recall on the 6.2 l engines. Ours is a 5.3 l engine. So far I'm seeing many people having problems but no official recall for the 5.3 l engines that are having THE SAME issue as the massively recalled 6.2 engines. This needs to be looked at. Our Vehicle only had less than 30k miles on it. We bought it new and have done routine maintenance.

ENGINE
The coolant control valve malfunctioned on this vehichle several times during the course of ownership. It causes the vehichle to run in limp mode. This part was replaced in July 2023 at ~40,000 miles as a result. The part again began to fail in june/july 2025 with a dealer visit and diagnostic in July. This causes a check engine light, reduced milage, reduced acceleration, constant fan running and fails state inspection Google searches indicate this is a very common problem, yet no recall has occured to date. The first repair was in warrantee and now the vehicle is out of warantee. If the part was not covered under the vehicle warrantee, the part and repair would have been covered by the part warantee. Becsuse of the initial powertrain warrantee repair, the part warrantee does not apply. This is clearly a defective design and part that requires recall and replacement at GM cost

This vehicle shifts hard and was identified to have a transmission valve issue. It should be under the same recall that other Chevrolet vehicles have with same issue. On top of this, Chevrolet cannot keep up with demand for this part making only 500 per week. I’ve been told it may be 2 months before I have my vehicle back.

ELECTRICAL SYSTEM
After a major HVAC repair involving the evaporator core (performed at a Chevrolet dealership), my vehicle began experiencing serious electrical issues. The second-row 12V outlet no longer functions, and the vehicle has gone completely dead three times while the engine was off due to the auto stop/start system — once while stationary on a major highway, creating a dangerous situation. Each time, the engine failed to restart automatically, and the entire electrical system became unresponsive.

ENGINE
On 7/26/2025 approximately 8:30pm (PDT), driving south on CA I-880 in third lane from right traveling at approximately 50mph when vehicle engine died and went into neutral gear. Dashboard alert indicated to press start engine button, but would not start. Managed to maneuver vehicle to right shoulder amid rush hour traffic. Fortunately, a CA Highway Patrol officer saw us and was able to render assistance. Vehicle would not restart or go into neutral after several attempts to restart engine. Special tow vehicle was called to give us a tow home. This incident happened after we received a Chevrolet recall notice back in May or June about the engine and did take the vehicle in for service on 6/10/2025. The dealership service recommended using higher weight oil and it would help mitigate any potential issue. Obviously, this was not the case. We were very fortunate to avoid any serious injury or damage on the highway due to engine failure.

Its been over a month and the dealership is unable to remedy this defect. I also called GM and they said the recall in incomplete and its in the preliminary stage. We are concerned that this is a serious safety recall and GM will not offer alternative solutions in a reasonable time.

Almost got killed doing 75 miles per hour, engine sputtered, totally shut down. Coasted onto an exit ramp thank God it was right there or we could of been killed. Tow truck towed to Davis Chevy Gainsville, they called me on Monday said good news I have a warranty bad news Total Engine Failure, will take 3-4 weeks to replace.

NO NOTICE FROM GM ABOUT ANY POSSIBE PROBLEMS....WE ALMOST GOT KILLED AND CRASHED along with the other drivers on the road. Thank God it was a Sunday and 6 am so not much traffic or it would of been worst.

SERVICE BRAKES
My wife was driving the vehicle and was pulling into a parking lot. The brakes failed and would not stop the vehicle. She pressed on the brakes very hard, multiple times, for several seconds, before the vehicle finally came to stop. She then proceeded into a parking spot where the brakes again failed to stop the vehicle promptly. Several lights illuminated and a “System Brake Failure 43 MPH Top Speed” message appeared, alternating with several other messages appearing. The vehicle is in for service at Classic Chevrolet in Granbury, Texas. They are telling me that they reset the codes and that the codes are not returning. I am extremely concerned that if I pick up the vehicle at this point, the brakes could fail again and cause an accident with serious injury.

UNKNOWN OR OTHER
There is an issue with the transmission when i accelerate at a slow pace. The car shakes and vibrates. Theres a possibility of an issue with the transfer case 4x4. When i turn the steering wheel and drive, it feels like it locks. It feels like 4x4 is on and theres a odd sound as well. I took my car to Hamilton Chevrolet and paid for inspection. They told me that there was no issue, but the issues i mentioned earlier in this message was mentioned to them. Those issues are still occurring. This is a recall issue but when i put my VIN number in, my car shows that there is no recall on it. There was many people who mentioned this problem.

POWER TRAIN
Our 2022 suburban with the diesel motor has had 3 separate incidents where by all accounts the wheels have locked up while driving. The incidents mirror what has been described in the recall N242454440. The first time the incident occurred, we were driving while towing a light load (boat ~2500 lbs) at a steady speed of 60 mph. While driving the vehicle shook violently once, and then again about 2-3 seconds later. I immediately pulled over suspecting that maybe there was an issue with our trailer. After finding nothing we drove home without incident. Shortly after this incident we had the transmission flushed for regular maintenance at about 50,000 miles. Approximately 5-6 months later the second incident occurred. While driving with no trailer, up a mountain in NC at a steady speed of 35 mph, the vehicle shook violently and then again approximately 2-3s later. Each time the vehicle shook a loud "BUMP" noise would be heard. The road was smooth and was later driven on without issue so it was not the terrain. I once again got out and inspected the vehicle and was unable to find an issue. We drove to where we were staying and immediately took the vehicle to a dealer the following day to be inspected. The dealer found no issues and we did not report any similar problems. The last incident occurred after another 8 months while towing a light utility trailer at a steady speed of 60mph. Same thing happened with a shake and loud BUMP. However this time it was not followed immediately by an other instance. Those came approximately a minute later and then again after about 10 more minutes. I cannot recreate the issue and it seems to be at complete random and is happening while driving steady rates of speed where the transmission shouldn't be trying to shift. It seems like a safety hazard that could cause an accident.

ENGINE
Our Chevrolet suburban has 57,000 miles on it. We have started getting a check engine light and I’m getting code P1098 for the cooling control valve. This is a very common issue on these vehicles I’m noticing now. From what I’m reading in February of this year (2025) gm gave this issue an e code so these valves would no longer be covered pay the powertrain and they would now fall under emissions for a much shorter warranty coverage. This has been and ongoing issue since 2020. These valves are also commonly found to be on national back order causing long lead times and driving of the vehicles without properly functioning. GM knows these are and issue and shortening the warranty is not the fix. These vehicles weren’t bought with a short warranty and shouldn’t be able to be reduced to a short warranty.

ELECTRICAL SYSTEM
Issue: The vehicle intermittently displays a “Key Not Found” or “No Key Detected” message on the dash and refuses to start, despite both original factory-issued key fobs being present and having fresh batteries. The issue began in summer 2023 and has progressively worsened. The vehicle has stranded our family multiple times, sometimes requiring a tow, family impact, missed obligations. Luckily for all urgent needs like trips to the ER or Urgent care, we were able to use our other vehicle, but we no longer have that vehicle and it is important that our sole vehicle be a reliable one. Impact: •Two emergency room visits and multiple urgent pediatric appointments affected •Forced to rely on one family vehicle for months •Paid for tow and fob batteries •Multiple instances of no rental coverage •GM and dealers often declined documentation or action due to the issue being “intermittent” ⸻ Request: We believe there is a systemic defect in the Suburban’s keyless entry/ignition system (likely receiver or antenna module). We request that NHTSA investigate and that GM be required to issue a recall or permanent repair for affected models. This issue poses a safety concern and has created financial and logistical hardship for our family.

ENGINE AND ENGINE COOLING
The contact owns a 2020 Chevrolet Suburban. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact stated that on several occasions while checking the oil level, there was no oil on the "dip stick". The contact stated that the engine consumed 2-3 quarts of oil approximately 4,000 miles. Additionally, the contact stated that while driving on several occasions at various speeds, the low oil warning light illuminated. The vehicle was taken to a dealer where it was diagnosed that the piston and piston ring were damaged due to excessive wear and sticking. The vehicle was repaired but the failure persisted. The vehicle was taken to the same dealer where it diagnosed that the cylinder head had failed and needed to be replaced. The vehicle was repaired but the failure persisted. The vehicle was taken back to the same dealer where the failure was not replicated. The manufacturer was not notified of the failure. The failure mileage was approximately 3,000.

POWER TRAIN, ENGINE
When attempting to drive from a stop light or stop sign, after taking your foot of the brake, the vehicle intermittently completely turns off. It will not immediately restart and you find yourself stuck in the middle of an intersection creating a safety issue. The vehicle has been in to Chevrolet to have this issue fixed once already and it continues to repeat. I doubt the dealer has been able to replicate the issue as they haven't gotten the vehicle back into the shop after it's been sitting there for a week. There were no warning lights, messages, or other symptoms. It has happened to both myself and my wife, most recently on or about 7/1/25 where it happened to my wife multiple times causing us to leave the vehicle at the dealership for service. Just to be clear, the issue with the vehicle turning off is different from the standard auto stop/start feature.
