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.

Brand new 2023 suburban radiator ruptured at 14,000 miles. Radiator and hoses replaced April 2024 and the car has ongoing issues since then. Most recently the car has a strong coolant smell and the dealership states they cannot find a leak or source of the smell. I have worked with 2 different dealerships on this matter. I was told that the radiator was a “poorly manufactured part” when it originally ruptured. No safety warnings ever appeared even when the oil was dripping out of the bottom after the original rupture. Oil and coolant had mixed in the coolant reservoir and no warning light ever signaled. The most recent coolant smell poses a safety risk to my families respiratory system as the manufacturer states they cannot find the source of the smell and have tried to return to vehicle to me twice with the strong odor coming out of the vents. We have had the coolant reservoir flushed several times as oil remains in their, hoses replaced, and ongoing service visits for a year for the same thing since the original rupture in April 2024.

The 2023 suburban started shuttering on idle and loosing power on drive due to a misfire in bank 4, the fuel injector was changed, but the problem persisted. And now the dealer says that I need to change all 8 injectors. 2900 job on a car with 54000 miles. Crazy

The engine seized while I was driving. The dealer discovered a crack in the engine block, which caused the oil to leak out. Unfortunately, the warranty had expired at 60,000 miles. The dealer replaced the engine with a brand-new one. So, I had to cover the full repair cost of approximately $6,830.29 out of pocket.

I was driving my family to San Antonio for a vacation when the vehicle suddenly stopped working. The display read restart engine but the car just abruptly stopped and I was forced to pull to the side of the road. Once the car came to a complete stop the car shifted into park and could not shift out of park. The car would not start, display would read conditions not met? I had to have the car towed to the dealership. They are giving me a hard time.
