2025 Chevrolet Tahoe Transmission Problems

While driving, your Tahoe started lagging and possibly misfiring, and a 'Service Four-Wheel-Drive' warning appeared. When you tried to park and turn off the engine, the parking brake wouldn't release even when you pressed the button, trapping you in two-wheel drive mode. You had to manually put the car in reverse and apply the gas to force the parking brake to disengage so you could shut off the engine. The issue likely involves the four-wheel-drive system, the electronic parking brake release mechanism, and a potential engine misfire that needs diagnosis.
