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.

POWER TRAIN
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.

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.

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.

STRUCTURE:BODY, FUEL/PROPULSION SYSTEM
I was driving down the road at roughly 30 mph when my fuel tank dropped. The front fuel tank strap fell off and the bolt was gone. The fuel tank drug on the road, which prompted me to stop driving. There are scrapes on the front of the fuel tank and the strap was bent. This is a huge safety concern because had the fuel tank cracked or fell off completely this could have caused a fire. Had we been traveling at higher speeds, this could have been a very serious accident. The potential for gasoline or diesel to ignite was absolutely present. It could cause a fire or even an explosion, potentially injuring occupants and causing damage to the vehicle. I was travelling with my kids and mom, so the risk of injury to multiple people was present. The manufacturers only response so far is that it was not an open recall issue so it is not covered. No warning lights came on when this happened.

ENGINE, UNKNOWN OR OTHER
I’m filing this complaint regarding a serious safety concern with my 2023 Chevrolet Suburban. The vehicle is affected by NHTSA Recall 25V274 related to a potential defect in the crankshaft or connecting rods. GM has confirmed the recall, but there is currently no fix available, and dealerships are not equipped to inspect the engine to determine if it’s defective. This leaves us driving a vehicle with a known risk of sudden engine failure, especially at highway speeds or while towing. In addition, my vehicle is also experiencing a transmission issues and is expected to be in the shop for up to three months for repairs. The combination of an unresolved engine recall and a failing transmission makes this vehicle unsafe and unreliable. We are a family of six with four small children (two in car seats, two in boosters). We purchased this Suburban specifically for safety, towing capacity, and long-distance driving. Right now, we are left without a safe or functional vehicle. GM refuses to provide a comparable rental and has offered only $44/day, which doesn’t cover anything close to what we need. We’ve attempted to work through GM and our local dealership to resolve the issue, but we’ve been passed back and forth with no solution. I’m concerned that GM is knowingly allowing vehicles with unresolved safety defects to remain on the road with families inside them. I’m asking NHTSA to investigate the handling of this recall and the delays in the transmission repair that are putting families like mine at risk.

Without warning my 2023 Chevy suburban started making a terrible noise, lost all power and died in the middle of the road. I was unable to restart the vehicle. It was towed to the nearest dealer 75 miles away and has been sitting there for 30 days with no idea when an engine will be available.
