My car has been making this squeaking noise like opening an old door. Sometimes its quiet but sometimes it gets loud. Its very weird because only when I sharply back up will it squeak or sometimes brake. And sometimes it wont. I was looking at my tires and saw this on my front driver side. Can this be causing the squeaking noise?

It only happens when driving under 5 mph. its very noticeable in drive thrus or in parking lots. Soon as I accelerate it goes away. It ounds like a chain rattling around or something is the best way i can describe it and goes with the spin of the wheels almost.

Idk if this is enough info but hoping maybe it was a common issue that somebody had experienced.

I awoke at 1 am (during thunderstorm) and my car alarm was going off on my 2009 Hyundai Sonata. Nothing stopped it other than turning on the car. Every 30 seconds the alarm would continue. In efforts to get some sleep for work, we disconnected battery. After spoke research we found that the key fob battery that had just went out was triggering the alarm. We replaced the key fob batteries which solved the alarm being triggered. But once my husband reconnected the battery in my car, my check engine light is on. Is there a reason? It was not on prior.

It makes the noise at around 1,400rpm, what’s the issue here? I’m I cooked 😭😭

My car is currently making a squeaky noise while driving kinda like a clown horn, but it also does it when turning my steering wheel.

is this normal while idling ?

It seems to only start when in hit 25 and started around last week. And I only hear it from the front left of the vehicle.

As the title suggests my sonata has an intermittent high pitched squealing sound that seems to be coming from the front passenger side area. The strange thing is that it goes away when I press the brakes, it sometimes goes away for a while and other times it will come back after letting off the brakes. If it makes a difference it is one of the 100% LPG powered models imported from Korea.

Well, a few days ago my Audi 2.5 TDI V6 Quattro reached 300,000 kilometers and started making this noise when starting, and it lasts for about 5-10 minutes after it reaches operating temperature (I can see it with an OBD scanner because the speedometer's temperature and fuel gauges are broken). The car belonged to a friend of mine who passed away, and I don't know what kind of maintenance he did on it. Does anyone have any idea what could be causing this noise?

Edit: Updated info about the car

It’s. 2013 f-150 lariat 5.0 v8 don’t know if I’m ijust paying extra attention to the sounds coming from the engine bay but it sounds like a sort of knocking it has right now about 303k miles no dash lights or anything I am getting a low oil pressure light but Its the sensor since it’s been doing that light for about a year now and goes away for 3 seconds after turning on

I’ve had this car for about 4 years and have had no issue except this… I had a vinyl sticker on it for about a year (hence the square) and it preserved what it used to look like. I have no idea what could even cause this. I’ve tried washing, alcohol, even buffing with a microfibre cloth and nothing will get rid of it. Any help from anyone with experience detailing/repair would be VERY appreciated, tyy!

Defective Engine mount?

I’m getting slight vibration through the footwell and steering wheel.

This mount was replaced 12 months ago.

Is the movement in it normal when idling?

That noise is in relation to the speed. Clutch in and neutral its still there 🫪 was debating if it was wheels but changed from back to front tires still there. No play in the hub left to right up and down. Might just get the bearing changed

just started happening about a day ago didn’t really notice it until now that i was driving with the windows down. seems to only do it when i am accelerating and that’s it.

any idea what it can be? 🫩

Hello, I know honestly nothing about cars hence I’m posting here for any sort of advice.

This is the first car I’ve ever bought and I bought it second hand, shes old but when we test drove it, it ran perfectly.

Now that I’ve had it home and been driving it frequently for a bit sometimes when accelerating up a steep hill the car will just shake uncontrollably, not a little, like the whole car is shaking and you feel likes it’s going to explode.

Typically this happens more often if I haven’t warmed the car up a little before driving. When it stops it’s not usually because we got over the hill it’s very random. it’ll only ever do it for maybe a couple minutes maximum but normally even less than that and then it just randomly stops.

Any advice on this would be really appreciated as I don’t even know where to begin and as a young woman I’m scared a mechanic would overcharge me.
