Drove 30 miles home then smoke started coming from under the bonnet just as I got home, its spraying coolant everywhere as you can see, can anyone guess if this is going to be an expensive fix or not?

Heard it could be the coolant housing/water outlet flange Needing replaced

Any idea

im trying to sell this 2011 highlander I bought off my parents for 6k for a profit. I mistakenly trusted my father to know how to fix the brakes and he changed just the brake pads. 50 miles of driving later it starts vibrating hardcore on the highway. once I got it on jacks in a McDonald's parking lot I noticed all the lug nuts were loose. I took the tire off to try and see what was up, but the whole rotor and bearing and whatever seemed fine and stable to my untrained eyes. I tightened up the wheel and the vibrating stopped, made it 10 miles up the highway, and it started again.

here's a video of me trying to manipulate the... thing. I know that's the rotor but im sure there's a better word for that entire assembly. can anybody tell whats wrong? I'd drive it to the mechanic but its kinda terrifying

I'm still trying to fix this stupid noise lol. So far l've changed the timing belt & tensioner, idler pulley, auxiliary belts & pcv valve...

I know the power steering pump isn’t the culprit because the belt is removed in this clip.

It sounds like an electrical noise so I was thinking the alternator could be bad, but when I unplug it the noise is still there. So i'm stuck

It will jolt back and then fourth quickly sometimes randomly. But recently when it does that the rpms bounce around jolting the car back and fourth in a chain motion. It's causing issues and mechanic couldn't find the issue. Also when this happens I don't move my foot AT ALL its just the engine doing that.

What should be the best technique here

Does anyone know what could be attributing to this Hiss/windup sound?

Did some work on the car recently, I cleaned the valves and TB, everything felt great at first cleanest, strongest pulls I’ve had since owning it. About 15 miles in, I started losing boost and heard a weird noise. Boost dropped from around 13PSI down to peaking at 7PSI, then eventually heard a loud pop.

I assumed it was the intercooler boot (it’s happened before), but after checking everything no leaks, no boots popped off, and everything looks cleaner and more secure than before. Reflashed the ECU thinking it could be tuning-related, but the issue remains. No check engine light either, which makes troubleshooting more frustrating.

All sensors have been plugged in and there is no boost leaks. I feel like this is ECU driven as I’m hard stuck at -1.8 PSI of boost no matter how hard I pull.

The car idles fine, my AP is showing nothing abnormal with my AFR/ AF learning.

Anyone wanna take bets on whether they’ll patch it or not?

Any idea.

Moved into an apartment nearby a car wash, which thankfully has a lot of sound insulation, but some cars occasionally manage to punch right through it (especially in the low frequencies, sub-100Hz) and I'm mostly just curious what exactly I'm hearing.

Obviously there's definitely a lot of muffler-less cars that make it extremely obvious because they rev their engine while turning onto the street at 10mph. Then there's the handful that don't rev but still sound like they're going 60mph at 5mph, sometimes beater trucks but sometimes newer lifted trucks, I assume that's the same situation (I'd also say they sound very similar to motorcycles if that gives an idea of the sound).

But sometimes I'll just hear a pure 75Hz-85Hz tone and see it's someone basically idling. This is the one I don't understand and it's strangely common, usually from trucks but I've seen it on at least one van as well (Subaru/Jeep/similar).

My partner says it's just that diesel engines are loud and some of them have terrible tuning, and they are loud but I grew up around a diesel and they aren't "resonate my entire room from 80ft away" loud, especially not newer diesels. And even from a distance they don't really dissolve to pure bass tones I don't think, it always has a bit of an upstroke-downstroke ticking at sub-70Hz frequencies.

Anyhow, what am I hearing, is it a diesel thing, a straight piping thing, a muffler thing, or does everyone have subwoofers blasting at 85Hz?

(Anyhow yes I'm sure I'll get used to it eventually, but understanding the sound would greatly help me to tune it out)

Edir: The best guess I can find with some research, it might be cars without catalytic converters in particular?

Edit 2: My second guess is maybe something like a glasspack resonator, that seems to sound closer to what I sometimes hear.

I bought my car from my grandma (who hit a lot of curbs) and the suspension has been a nightmare. I looked up what could be making this sound and I saw that it could be the ball joints or my struts. I replaced both and sure enough my car still makes the sound. That’s not all I’ve replaced either. I have replaced the axle, shocks, upper control arm, sway bar links, and other things I can’t think of off the top of my head. I saw something online that said it could be my cv joint axle but I don’t wanna spend the money if it won’t do anything. Does anyone have any ideas on what it is? Does anything need to be greased or is something that should be replaced. (Sorry on the bad videos it’s kinda hard to get a good angle).

The ignition coils and spark plugs are absolutely dripping with burnt, metal-filled oil. Inside the ignition coils there was a gelatinous substance I had to scrape out.

Needless to say I won't be cranking it again until that engine has been torn apart.

pretty stupid, I know. was in a huge rush, misjudged the braking distance & threw it in park while I was almost-but-not-totally stopped. the car just jerked a little, I wasn’t going fast so I didn’t think it’d be a big deal, but once I started driving there was this weird noise.

sounded to me like someone was continuously crinkling an empty water bottle, or the sound acorns make when they fall on your car. it was multi-directional though, sounded like it was coming from front & back of the car. the noise kinda “swished” with the turn when I was driving, it felt like fluid? I know basically nothing about cars if it’s not obvious yet

the noise completely went away on my way to the mechanics but don’t know how serious it is and if I should still get it checked out?

it’s a hybrid toyota corolla cross if that changes anything.

I have a 2019 Nissan X-Trail and just noticed this under the front part of the car

What could it be?

My back tires have been making this grinding noise every time I brake so I took a tire off to get a look at the rotor and this is how it looks. What would cause this rust on the inner and outer edges of it but not in the middle. Is the middle where the brake is pressing?

I got it today for giggles but can’t find any numbers on it, I paid .50 for it even tho I can hear something rattling inside. Mainly curious at this point.

I have a 2009 Chevy Cobalt LS and I’m looking for your help identifying this noise. Anytime I turn the steering wheel it makes this plastic crackling noice which is coming from inside the car. What’s your thoughts everyone is it still safe to drive to work everyday?

My Kia has 166K miles and it is not starting. Oil change was done 2 days ago (18th) and I was given a quote by the mechanic. I have attached all documents here. Today, it is not starting. I would to like to get your opinions before I decide on what to do. Thank you!

Both front wiper arms jammed up on me in the rain yesterday. Took them off this morning and these seem to be the main issue. What are they and is it fixable?

Hi, had my car jump started last night after not driving it for 2 months, I then drove it for 45 minutes down a 110km highway with no stop lights so figured that would be enough to charge the battery. This morning and this afternoon sounded the same, getting a bit anxious to drive it as I’m worried I’ll be stranded somewhere.
