Why does the start-stop function in the 2009 Smart cause the vehicle to stall? It usually happens when waiting at a red light. When the start-stop function is on and the light turns green, I find that the vehicle has already stalled, and I have to wait a moment before I can restart the vehicle.

Dear fellow car enthusiasts, I've been experiencing an issue with my 2008 Yaris where it occasionally stalls while idling at a red light. After restarting, it might stall again at the next red light. This happens two or three times, but then it runs fine afterwards. There are no error codes on the dashboard, and when I took it to the repair shop, the diagnostics showed everything was normal. Does anyone know what the problem might be?

My HS's electronic start-stop function isn't working. Is there any solution?

When I put it in drive, the engine stalls. I have a 2017 model 95 with over 70,000 kilometers now. Recently, I've encountered a problem where the engine stalls when I put it in drive while waiting at a red light. It's happened a few times already, but the 4S shop couldn't find the issue. Has any fellow car owner experienced this problem?

Why does the car show a transmission fault warning during a cold start, but it goes away after waiting and restarting?

While driving normally and making a U-turn, the gears suddenly started jumping. The engine didn't stall, but there was no power. The engine malfunction light came on, and the ECO indicator disappeared. After restarting, the car drove normally again, but the malfunction light remained on.

4WD light is flashing, and the vehicle won't start.

Is there a problem with the car if the auto start-stop system, once activated at a red light with a deep press, automatically reignites due to the long red light duration and causes noticeable shaking?

Today, while driving, the engine warning light suddenly came on. No other lights were on, but I felt the engine trembling and it lacked power. After driving for about 150 meters, during idling at a red light, the engine vibration was quite noticeable. When the light turned green and I accelerated, the trembling became more pronounced and it lacked acceleration. I pulled over immediately, waited for about 10 minutes, and after restarting, everything was back to normal. I restarted a few times afterward and everything was fine. The last time I started the car, I drove a few kilometers home and it was normal too. Has anyone experienced this issue? Does anyone know what might be going on?

Jeep Liberty, 2012 model with over 170,000 km. It often stalls, especially when reversing with the AC on. When waiting at a red light with the brakes fully pressed and the AC on, it occasionally stalls too. I can't read any error codes. Does anyone know what might be the issue? Could it be a compression problem?
