My Haval HS has been driven for over 12,000 kilometers. Today, after going out and just returning home, the engine emission fault appeared. When I put it in reverse gear, there's no response, but it drives in D gear. Is this issue serious? I'll go to the 4S shop for a checkup tomorrow!

2011 model of the Chery Tiggo 4WD automatic. Recently, while driving in D gear, it feels like it automatically shifts to neutral. The engine revs, but there's no power, and it takes several seconds to regain power! Seeking help from fellow car enthusiasts, what's going on???

Mitsubishi Galant D gear won't engage, does anyone know what's going on?

Guys, I'm really freaking out. Just now, while driving smoothly, the D gear light (the one on the gear shift) started flashing, and the dashboard showed "Please shift to D gear first before selecting the appropriate gear." I was in a panic and didn't know whether to press the brake and shift to P gear or shift to P gear and then to D gear, and then it prompted "Speed too high to shift into D gear (or maybe P gear, I forgot)." It was terrifying, the car felt like it was in neutral and there was no power when I pressed the accelerator. I managed to park on the side using inertia, shifted back to P gear, and then to D gear, and it resumed normal driving. I want to ask you guys, what's going on here exactly? Is there a specific part that's malfunctioning?

MG HS experiences a strong jolt when shifting from P to R or D when the car is cold. This has happened many times. When I went to the service center, the technician connected a computer and reprogrammed the transmission for gear learning. It got better, but after some time, the jolt returns when shifting gears with a cold engine.
