The 2023 standard version Rubicon has an issue where if it's left for two nights, the brake pedal becomes very hard in the morning when I press it to start the car. I'm wondering if anyone else has experienced this issue with their Jeep. I went to the 4S dealership, and they checked the vacuum pressure, which was at 620 and held for a morning without any signs of leakage. Is using a smoke machine the only way to check it? Sigh 😮‍💨

My 2018 automatic car with a turbo is losing engine oil. I've checked with the service center; there's no blue or white smoke from the exhaust, and there's no sign of oil leakage on the engine exterior. Both the oxygen sensor and spark plugs are clean. The service center couldn't find the problem. Anyone knows what might be wrong?

It seems like your car's brake pedal is hard to press in the morning when starting the engine, but it becomes lighter after the engine is on. This issue didn't exist before, and you're wondering if it's due to a vacuum pump leak. The dealership mentioned it doesn't affect driving. What should you do?

Hey folks, my headlights work during the day but not at night. Has anyone encountered this issue before? Help needed!

Hi everyone, has anyone experienced water seeping into the back seat after heavy rain? I can't find the cause, and there are no signs of leakage.

Dear car enthusiasts, has anyone added a catalytic converter cleaner to the fuel tank of a 2011 manual Touran? After I added this kind of cleaner, it started emitting white smoke and the check engine light came on. Has anyone experienced this situation?

17 Leading Edition... 220,000 km driven. The engine cylinder head is damaged, causing water leakage. Has any other owner encountered the same issue?

This morning while driving, there was a sudden jolt as if the car was about to stall, but then it was fine. Has anyone experienced this? What could be the issue?

I'm driving a 2017 model 1.4T automatic 2WD luxury version. Last year, I replaced the recalled vacuum pump. When I used to drive it daily, I didn't notice any issues. Recently, I've been using the car less, and after it's been parked for a day or two, the brakes feel hard when I start it in the morning. I wanted to check if the vacuum is sufficient, so I tried coasting in neutral and after pressing the brakes a couple of times, they become hard. I want to ask fellow car owners if they've experienced the same situation. Thanks.

When driving on the highway, if the steering wheel starts vibrating when you exceed 100 km/h and the vibration becomes more pronounced at 120 km/h, it could indicate a few potential issues. It might be related to wheel balancing, alignment, or tire issues. You might want to have these checked by a professional to ensure safety.
