The 10-year-old Galant has driven over a hundred kilometers on the highway, and the gearbox is making a whistling sound. What's going on? It seems fine when the car is cold.

The battery is new, and the car starts fine when it's cold. But after driving for about ten minutes, sometimes when I stop and try to restart, it makes a squeaking sound and won't start. If I turn it off and then gently start it again, it works. I'm asking if anyone knows what might be causing this issue and if anyone has experienced something similar?

I've got a 10-year-old imported 1.6 Mazda3. Lately, I don't know what's happening, but I can shift to the D gear, yet it doesn't show on the screen. I have to jiggle the gear lever a bit for it to display. Feels like a loose connection. 🤦‍♂️ Other gears are working fine.

My 10-year-old car makes a strange noise when I accelerate hard or when going uphill. The sound is like "pop, pop, pop." Does anyone know what the issue might be?

My car is automatic, and I recently noticed that when I start on an uphill, there's a kind of "bo bo" sound when I press the gas. It seems like it's coming from the transmission. But when I'm driving normally, there's no problem. Even when I hit the gas hard or drive on the highway, it's fine. It's just when I start on an uphill. 😂

The loudspeakers in my RDX are making a popping sound and sometimes they fail. Previously, there was an occasional popping sound when starting the car cold, but recently it happens every time I start the car. The car's Bluetooth seems to be working fine, and the screen shows that music is playing, but there's no sound. Sometimes restarting the car fixes it, but sometimes it doesn't. This is happening more frequently now. Has anyone else experienced this? What could be the issue?

I bought a second-hand 2014 Kia Sportage, and the exhaust smells really bad. I hadn't driven it on the highway before, but a few days ago I did, and the engine warning light came on. The check indicated an issue with the oxygen sensor. After replacing it, the error code was cleared, but a few days later it came on again. It seems fine when not driving on the highway, but as soon as I do, the light comes on and stays on. Can any experts advise on how to fix this issue?

I've driven my father's manual Volkswagen Santana for over 10 years. It's quite durable, performs well on the highway, and the wind noise insulation is decent. It hasn't had any major issues. I'm planning to switch to an SUV to experience driving one. I want to ask T-Cross owners: Is the T-Cross reliable? How is the driving experience on the highway, and what about the wind noise insulation?

The 10-year-old 1.5 manual car experiences severe vibration in the gas pedal at 3000 RPM in any gear, making it difficult to press. Does anyone have a solution for this issue?

My 10-year-old 1.6 manual Peugeot 307 sometimes makes a sharp "squeak" sound, like metal rubbing against metal, when I'm shifting gears, releasing the clutch, or letting off the accelerator. Does anyone know what might be causing this? 🥲

Hi everyone, I need some advice. I have a 2016 Nissan X-Trail with 70,000 km on it. The AC blows cold air for about 10 minutes, but then the airflow decreases. If I turn off the AC for a while and then turn it back on, it works fine again, but after a few minutes, the airflow decreases once more. Alternatively, if I turn off the AC, the airflow increases, and when I turn the AC back on, it runs normally, but after about 10 minutes, the issue returns. What could be the problem? Thanks!
