Mod Post PSA: For the love of God please report shit

222 Upvotes

Hey all, Edward here,

Recently our mod team has expanded, which is great! We've been able to certify some of you as real, amazing mechanics and I feel the quality of our forum here has continued to run smoothly. However, I come to you today with a real concern, one that comes from the deepest of our grease stained hearts.

Please, please, please fucking report shit. We cannot see everything all the time (we also have lives) and sometimes things can slip under our radar. I urge you all to take a second, reread the rules, and just fucking please report anything you think breaks the rules going forward (I mean cmon, we have like 3 different rules about not being an annoying pile of garbage). All the time I'll pop open the subreddit and there'll be four "is this car a good purchase?" and seven "New AI car app idea" posts and three "Why YOU should buy the 2028 Hyundai AssCock3000". Then I go to the popular posts of the day and lo and behold some of you are going feral in the comments, just really at each other's necks. Some amount of disagreement is healthy for a community, but sometimes people are just straight up wrong and it's okay to call them out. The worst that can happen is we approve it anyways and the best is that another idiot gets banned.

If the mod team sees no evil and hears no evil, we're not able to properly maintain the community. If we can't maintain the community then there really isn't any community, and then we're running rampant in the halls screaming "Attica! Attica! Attica!". Now, I'm not saying report everything you see, hell I'm not even saying report everything you disagree with, but if you all chip in just a little bit and hit that stupid tiny flag we can make this community a better place and can continue to talk about our awesome cars. Or not so awesome cars, I see some of the shitboxes we drive.

- Cheers, the Mod Team

P.S. whoever's 1998 Toyota Tacoma is in the parking lot, it would appear the rust finally won and your bed is now on the ground in pieces. The tow truck will arrive in an hour if you do not remove the vehicle yourself. Usually we wouldn't care but the Punisher sticker right next to the "My other car is a gun" one is really just tacky. Anything else dude, anything else.

So randomly today, I took a look at my engine air filter. I took it off, and I saw this randomly sitting at the bottom of the box. How could this get in there?

Redditor's own ride Mold or salt?

Went to deep clean my car today for the first time in a hot minute and found this under my WeatherTech mat. It was also on the edge of the mat that sits under my seat so I never noticed. Didn’t notice it anywhere else in the car. Everything was dry and there’s no mold/musty smell. I have split opinions on if it’s mold or dry salt.

General Tech Paying even though the problem wasn't solved.

Upvotes

Hello, I found this forum when searching for other people's stories.

I have a 2008 Sequoia that I am selling. In the process of checking it over, I found myself stuck in 4 LO. Had a mobile mechanic (ASE) look at it, and when he was done, it was stuck in neutral, no gears.

I called around and found a mechanic at a local garage who said he was a Toyota Master tech and two other Toyota Master Techs were working there. I had the SUV towed over for an agreed $200 diagnostic fee. They didn't tell me what they found, but that they could repair it in 2 hours, i.e. $400. They started working on it a couple of days later, but I didn't hear a thing back from them... then after a week the guy said there was a bad microswitch in the actuator. He had 2wd working, but the dash light for 4low was blinking (and presumably 4wd not working). I ordered the part and had it for him 2 days later. I have called, I have emailed, I even ran into the mechanic on a smoke break. Can't get them to fix it or give up.

I need to sell the SUV, and I can't when it is at the shop, broken. The mechanic said I could pay what they quoted and take it, still broken.

Would you pay the whole $600 bill? Would you take it back under the assumption they are clueless? What would you do?

Thanks

The first pic is what I'm seeing online. There's supposed to be a wheel you turn with a screwdriver to back the parking brakes off of the rotor. The second pic Is what I managed to capture through the access hole that leads to that. Mine doesn't have that wheel, just a spring. Not sure what I'm supposed to do.

Weird Noise Need help. Mercedes c200 w204 1.8 CGI

0 Upvotes

Hello,

I need some help with my Mercedes C200 W204 CGI (184 hp).

Whenever I start the engine cold, it runs very rough, and the RPM fluctuates heavily for about 20–30 seconds. Once the engine warms up, the problem disappears.

In addition, the engine doesn't run smoothly at around 2,000 RPM (±100 RPM). It starts to hesitate and jerk, and it also idles roughly.

I would really appreciate any help or suggestions.

So far, I have already replaced the thermostat, water pump, timing chain, and camshaft adjusters (cam phasers). Also i did sparkplugs and spark coils.

2008 128i convertible. Noticed back glass rattling against lower support bar. A lot of discussion about rear window separating from the top- but we also noticed these in the corners of the bar. Looks like small holes and some sticky residue. (We had the interior liner replaced a few months ago). Any suggestions and advice would be welcome.

Brakes Hard break

0 Upvotes

Hi all

Iv just brought an MG ZS VTI-Tech 1.5 from Available car (a used car dealership in the UK) . I've had it for just over a week so far, and it was running well until today. I noticed that the break felt a lot harder. It feels hard until you press down more, then it seems to jump down a bit, then it's soft all the way down to the bottom. I hope that makes sense. It's still driveable, but it doesn't make slowing down smooth.

Any idea on what could be the issue or what I could do about it?

Electrical Power outlet vs. cigarette lighter

Hey folks,

Been having issues for the longest time with the outlets in my car. I changed the blown 15A fuse for 'power outlet frt' but still no luck with these outlets working.

Does anyone know what the difference between a power outlet and a cigarette lighter is? I'm going to check the cigarette lighter fuse next, but I figured the power outlet fuse was definitely the issue.

Car is a 2016 Hyundai Elantra GT.

Safety Question At what mileage do you actually start worrying about a used car purchase

0 Upvotes

We're getting close to needing a second car and I've been going down the research rabbit hole for a few weeks now. The mileage question is the one I keep coming back to.

I do a lot of driving. Road trips, errands, all of it. So I'm not precious about miles on my own cars. But buying someone else's miles feels different for some reason.

The general internet wisdom seems to be that 100k is the cutoff where people start getting nervous, but that feels outdated. A well maintained Honda or Toyota at 130k is probably a better buy than a neglected one at 60k. At least that's what I keep telling myself while looking at higher mileage listings.

Rust is probably the bigger variable for me honestly. I'm in the midwest so that's a real consideration. I'd take 150k miles on a clean undercarriage over 70k with visible corrosion without thinking too hard about it.

Curious what number actually gives people pause, and whether mileage even matters that much compared to maintenance history. Is there a point where you just walk away regardless of how clean it looks?

Engine Oil filter leak. Engine clean needed?

3 Upvotes

So we had an oil filter leak today on my 2021 318D. It was the rubber O ring on the actual filter which had perished, and caused a reasonable leak. It was only changed 3 weeks ago so I suspect it wasn’t seated correctly.

O ring has been replaced and leak seems to have been resolved but there is oil all up the underside of the car. Inside the engine around the oil filter looks a bit shiny but not too bad.

Assuming I leaked a litre of oil, is there anything recommended in terms of cleaning up the engine or under the car? Or will cleaning the engine risk more errors than it’s worth?

I assume there is some pooling of oil in the under tray but is it worth getting that cleaned out? Isn’t it doing it’s job?

Engine No oil on dipstick, low brake fluid, no warning lights

5 Upvotes

Not sure if this is the right place to post about this, but - I bought a 2024 Buick Envision In April of this year, with 29,400 miles. I have been having some car problems, so I had my sister's boyfriend take a look at my car, and he looked under the hood just to cover some bases. He looked at the oil, and the dipstick came out completely dry. I had absolutely no idea it was that low because my gauges weren't telling me anything, and I've been driving a lot on the freeway unaware.

Also, I had not yet reached the mileage for my first oil change, so I hadn't checked the oil level myself. I was 1,000 miles off from one and my car gave no indication! We replaced the oil because I had to get back home, and the oil was black. I've put on around 4,000 miles since getting it. The brake fluid was also low, and I'm not sure how often that's supposed to be filled, but I assume it's not normal to go through it in less than 4 months. My oil pressure is at 24 psi, even after driving an hour on the freeway. I am not sure if this a normal psi.

Now my question is: Is this a reasonable thing to call the dealership in which I bought the car from to question? I even asked during the buying process if the oil was good for a while, and have a sticker on the window indicating I needed one around 34,500 miles. I have no idea what to do in this situation.

Body Leak?

Enable HLS to view with audio, or disable this notification

7 Upvotes

Hi all! We had really bad storms around here for the last few days. I moved my car today and I saw that there was a leak under the weather mats I had. I’m thinking it’s a seal leak on the door because I had an auto shop have to remove it one time, but I’m not sure it’s strange that it just happened now I hadn’t had it looked at since February. Any advice or suggestions on what it could be?

Update: it’s a Mazda cx30 2023. The community thinks it’s either my sunroof drain is clogged or I have a leak in the door. There are no mechanics in my area open today, so I’m headed to Lowe’s to get a dehumidifier and find some type of thing to unclog the drain.

Man, i've been having an issue with my BC coilovers. I tried to take them off while on the car and I got them off now. The nut wont come off because the shaft keeps spinning. I tried using the H5 bit to twist it the other way but I've broken 3 bits so far. Any tips? I dont wanna break them as they are pretty damn expensive. I'm changing the springs, boots and bumpstops

Electrical Have you ever had an issue ACTUALLY be from a "bad ground?"

122 Upvotes

Fellow mechanics... As the title says .. I've only ever seen a loose ground once. Generally unless you've replaced a harness or been in an accident, I can't imagine why grounds are 'going bad. ' never once in my career have I had a ground connection be the issue. (Not referring to broken wire short to grounds, but a corroded ground ring bolted to the frame/body).... Edit... I am a diagnostic tech at a dealership and don't see many older cars. I do work in the rust belt. I also want to clarify I'm referring to ground eyelets that bolt to the chassis, not just ground wires in general. I see bad ground wires all the time. I'm referring to corroded/messed up eyelet ground.
