2023 CHEVROLET SUBURBAN Complaints

Check engine light came on Then : message saying power reduced. Then: Service transmission, unable to shift soon. While driving on the highway. Vehicle has been at dealership for a month with no idea on when parts will be available. They say they have no idea on when a valve body part will be available.

The engine stopped working. I was stranded on the highway and needed a tow. It was towed to a Chevrolet dealership in Alexandria MN, where it was diagnosed with a spun rear main bearing in the engine needed to be replaced. There were no warning lamps or anything prior to the engine completely shutting off and not being able to start again.

The contact owns a 2023 Chevrolet Suburban. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

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 need replaced because the common lifters problem in 5.3L engine. It happens at 41k and now at 100,00k. Dealer don’t want to admit this safety issue and need to be investigated this is not acceptable.

Transmission valve control failed. Rear wheels locked up. Vehicle downshifted quickly. No injuries. Vehicle is at dealership for repairs. No warnings.

Lifters failed again for the second time. First time was at 41k miles fixed by dealer under warranty, it happened again today 05/02/2025 with 100k miles on the engine with ticking and cranking noises and being told it need an new engine. 5.3L suvs need to be investigated and be recalled for engine failure it is a common issue please help.

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.
