2024 Chevrolet Traverse problems

“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…”

“I have a 2024 Chevy Traverse with 32,000 miles. It has been using a quart of oil every 4,000. Bulletin states less than 1 quart every 2,000 miles is okay. Unbelievable that a new car is allowed to use any oil. Did not know I purchased a two‑stroke engine. If someone does not check their oil they could be running 2 quarts or more low in between oil changes, which could damage the engine. Just checked my level, see photo. Drove 3,000 miles and the level was almost at the bottom of acceptable. I still have 60% oil life before the next change. After another 1,000 miles probably would have gone below the low line. Not good for the engine. Mentioned to the dealer during the first oil change and they started overfilling. Told them to stop that as that is not good for the engine. I am worried the engine will fail prematurely.”

“Master cylinder failure on interstate caused complete loss of braking. No accident. Shop replaced master cylinder per GM bulletin. Warning light for brake assist failure came on and pedal went to the floor. This could’ve ended in a mass casualty situation, thank god we were in wide open territory and could coast to a stop which took over a mile in neutral.”

“A software update caused the warning lights to go on and off despite no issues surrounding the vehicle (lane assist, forward collision warning). While driving on the interstate going 70MPH the forward collision light flashed a warning which then reduced the cars speed from 70MPH to 40MPH within a very short period of time. This is a huge safety concern and no accident happened as there were no other vehicles around at the time.”

“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 NHTSA to investigate the quick-connect coolant fittings across the entire LK0…”

“My 2024 Traverse was delivered with defective third-row seat headrests that do not return to their normal upright position after being folded, compromising passenger head and neck protection in a collision. On October 28, 2025, the vehicle developed a coolant leak confirmed by the dealer, but repairs have been delayed due to a national parts backorder, creating a risk of engine overheating or sudden breakdown while driving. Additionally, the front brakes began squeaking excessively about one year into my ownership, and the brake pad wear sensor shows only 18% life remaining at 18,454 miles, which raises concerns about reduced braking efficiency and increased stopping distance. All issues have been reported to an authorized dealer and remain unresolved except for the third-row headrests. These conditions pose significant safety risks to occupants and other road users.”
