The first time this happened was in 2024, my Traverse started to sound like a go-cart, loss of power to accelerate, and exhaust smell would leak into the cabin. Being active duty living on base with one car it was more convenient to use an insured Mobile Mechanic. - Front bracket that secures the Exhaust Manifold/ Catalytic Converter in place welds failed resulting in the parts to be under extreme additional stress breaking it. This has happened every year since, everytime Chevrolet/GM customer service has been contacted and we are told that my VIN year make and model are not on the Special coverage list and there is nothing they can do. Three Catalytic Converters in three years from an engineering flaw is not normal wear and tare.

What owners say
1. What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple critical factory components and electronic systems failed or malfunctioned on this vehicle: • Electronic Brake Control / eBoost Software System: The factory brake-life tracking software severely malfunctioned, miscalibrating the braking system metrics. Furthermore, despite subsequent system recalibration confirming over 90% friction material life remaining, the braking system continues to suffer from persistent, severe brake noise. • Exhaust / Emissions System: A premature mechanical failure occurred in the exhaust system, resulting in a loud passenger muffler defect. • Electrical Charging System: The primary vehicle battery suffered from a premature voltage drop/depletion and completely failed standard diagnostics. • Restraint System: The third-row head restraints suffered from a factory defect causing them to jam (subject to active Customer Satisfaction Program N262558680). • Inspection Availability: Yes. The vehicle, its electronic systems, and all diagnostic readouts/replaced components are fully available for physical or electronic inspection upon request. 2. How was your safety or the safety of others put at risk? Safety was compromised across multiple vectors: • Braking Unpredictability: Driving a family vehicle with an active, unaddressed brake system software defect and ongoing noise creates extreme uncertainty regarding emergency stopping capabilities and electronic brake-assist behavior. • Crash Injury Hazards: The jammed third-row head restraints directly compromise the effectiveness of the vehicle’s passive restraint system, increasing the risk of severe whiplash or head injuries to rear passengers (including children) in a collision. • Uncontrolled Stranding: The combination of a depleted primary battery and severe system faults puts occupants at risk of sudden electrical failure or entering "limp mode," risking power loss in high-speed or
2024 Chevrolet Traverse, 2.5L turbo (LK0). The cooling system has repeatedly lost coolant through quick-connect hose fittings. On 4-3-2026, at 36,650 miles, Washington Chevrolet replaced the radiator inlet hose under warranty for coolant loss. After that repair the vehicle kept losing coolant, and I have had to top off the reservoir repeatedly. No low coolant warning or dash alert has ever appeared. On 10-14-2026, at 49,066 miles, the same dealer found the outlet hose at the coolant surge tank leaking, rated it Critical, and quoted $480.30 to replace it. The dealer declined warranty and goodwill coverage. Safety concern: coolant loss with no driver warning can lead to overheating, reduced power, or engine shutdown while driving, including at highway speed. GM has acknowledged quick-connect coolant leaks on this vehicle under Special Coverage N262546590 (radiator inlet hose, 2024-2026 Traverse) and bulletin PIT6494A (the same seal failure on GM's 2.7L turbo trucks). My second leak is at a different quick-connect in the same cooling system, which those programs do not cover. I am asking the federal safety agency to investigate the quick-connect coolant fittings across the entire LK0 cooling system, not just the radiator inlet.
My 2023 traverse rs experienced a loud grinding noise and sudden loss of power, almost like i slammed the brakes on while moving. I was in the middle of the road and i could have been rear ended. 10/12/26. This matches the GM recall N222389310 exactly but my vin is currently excluded. I am also experiencing a heavy vibration since 9/13/2026 similar to diving over rumble strips, it is intermittent and will not throw a code, its been to the GM dealership where new transmission fluid was put in, however started again, that did not solve the problem . GM does not have a recall for torque converter clutch they are aware and had put out a technical service bulletin TSB-23-NA-072.
My car the steering gets hard to turn I have to turn car off and bk on also at light it lose power and roll and come back on sometimes things work and some times it don’t I have to shut off car and restart for things to work correctly and sometimes it work for a little bit while then start doing it again also feel funny when driving
The high-pressure fuel pump/fuel delivery system failed on my 2023 Chevrolet Traverse at approximately 47,480 miles. The vehicle generated diagnostic trouble code P0091. An authorized Chevrolet dealership inspected the vehicle and documented that the high-pressure fuel pump was “internally faulty” and required replacement. The vehicle and/or failed component may be available for inspection upon request, depending on whether the dealership retains the component after replacement. This failure presents a significant safety concern because the high-pressure fuel pump is responsible for maintaining proper fuel delivery to the engine. Failure of this system can result in hesitation, reduced engine performance, loss of power, stalling, or failure to start. A sudden loss of engine power while traveling at highway speeds, entering an intersection, or merging into traffic could increase the risk of a crash and endanger vehicle occupants and other motorists. The malfunction was confirmed by an authorized Chevrolet dealership through diagnostic testing. The dealership identified code P0091 and specifically documented the high-pressure fuel pump as internally faulty. To my knowledge, the vehicle has not been separately inspected by General Motors, law enforcement, an insurance company, or another independent investigator. Warning lights appeared intermittently prior to the diagnosis. The lights would illuminate and later turn off, despite the underlying malfunction still being present. I am concerned that a critical fuel-system component experienced an internal failure at only approximately 47,480 miles. I am requesting that the federal safety agency document and evaluate this failure to determine whether similar high-pressure fuel pump failures are occurring in other 2023 Chevrolet Traverse vehicles and whether this condition represents a potential vehicle safety defect.
I own a 2023 Chevrolet Traverse. While driving, the vehicle suddenly began jerking very hard during acceleration and shifting. The Check Engine Light illuminated, and the vehicle became unsafe to drive because the transmission was not operating normally. I was concerned that the vehicle could suddenly lose power or fail while driving in traffic, increasing the risk of a crash. I took the vehicle to a Chevrolet dealership for diagnosis. The dealer found the transmission fluid was burned and diagnosed transmission trouble codes P0797 and P0700, indicating an internal transmission problem. Transmission .PDF Before the failure, I experienced harsh shifting and jerking that became progressively worse until the warning light came on. The problem has been confirmed by a Chevrolet dealership. The failed transmission is available for inspection upon request. I am submitting this complaint because I believe this transmission failed prematurely at approximately 68,933 miles. I am concerned that other owners may experience the same failure, creating a serious safety risk if the transmission loses power or fails while the vehicle is in motion.
Lost power to transmission at 36k miles. Transmission replaced by GM. Currently, the vehicle lost transmission power while driving and had to be towed to dealership. Notified that the transmission needs replaced again
The contact owns a 2023 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle unintendedly shut off, the instrument panel went black, and the vehicle lost motive power, and the vehicle lost power steering and power brakes functionality. The vehicle was shifted to neutral(N) and restarted, and regained power, and the vehicle returned to normal functionality. The failure also occurred while depressing the brake pedal. There were no warning lights illuminated. The failure had become more frequent and occurred approximately 3 - 4 times a day. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 20,000.
After refueling we re-entered I495 Northbound. While traveling in the fast lane of traffic my vehicle shut off. I lost all power, including the ability to use On-Star. The vehicle refused to start for thirty minutes. This problem repeats within a mile of refueling. The vehicle has been taken to the dealer. The first time the said it was a sensor in the stable trak. This last time they claimed a bolt on the battery was loose. There was no pre-warning the car just stopped in rush-hour traffic on the busiest highway in America.
