Be polite. Treat those asking for help with respect, and answer without bias toward them, their situation, or their knowledge (or lack thereof) about the repair issues. Also respect those that take the time to answer questions and remember that many are professional mechanics, who normally get paid very well to diagnose automotive repairs.
We're here to help you, but not to assist in negotiating with mechanics (this is business/life advice, not repair advice) or to tell you what car you should buy.
*CAR REPAIR RELATED MEMES ARE OK *
Get OBD codes! If you have a Check Engine (CEL) or Service Engine (SEL) Soon light on, get the codes read and have them available if possible befoer posting. You can have codes read at Auto Zone, Pep Boys, O'Reilly's, etc., for free in most states. Write them down. They will have a letter followed by four numbers, for example "P1234". You can get a code reader from Amazon that works with 1996 and up vehicles for about $15. It will let you read and reset the codes.
Some examples of things that are NOT GENERALLY ALLOWED: links to articles or videos that are for profit, professional-level body work repairs, detailing or cleaning questions, aftermarket car stereo questions (/r/CarAV), car reviews (r/Cars), new & used vehicle recommendations, price comparisons for tires, stereos, exhaust, etc, and especially questions regarding cost of repairs or the legitimacy of a mechanic's quote. *
*Remember that posting here is not a substitute for using Google. Most repairs have already been covered multiple times somewhere in great depth that will satisfy your needs. YouTube has many helpful topics. *
If you still aren't sure about something you are about to post, please look at the links down below for other subreddits that might be better suited for your question, or message the moderators.*
Have as much information as you can about the issue before posting. Attempt to investigate the repair issue on your own. Take pictures, crawl under the car, look under the hood. By making a good attempt to narrow down where and what may be causing the problem you save those trying to help many steps in diagnosing the problem.** Be sure to also include the year, make, model and engine size of you car in your title, along with your main issue.** For example "2003 Ford Crown Victoria 4.6L exhaust manifold bolts rusted off" would be an acceptable post title. If you do not take the time to include this basic information your post may be removed until it is revised.

I have a 2011 volkswagen jetta with about 127,000 miles on it. A few times while I’ve been driving, if my car is idling (ex: behind red light), sometimes the engine will turn off and the red battery symbol will appear. I’m unable to accelerate and the wheel is very stiff. I have to put the car into park, and then turn it back on. Then, the symbol disappears and I’m able to drive like normal. Generally, I have no lights on the dashboard at all. The only other “issue” my car has is that it sometimes shakes too roughly when idling, but the solution is the same (turn the car off and turn it back on).
We took it to the mechanic and no codes came up at all; all car components checked out fine on the computer. What could be the issue causing the car to just shut off?
Hello everyone, I have a 2014 mini Cooper F56 manual with a 1.5L B38 engine. I bought it used half a year ago and ever since the clutch biting point has been near the floor, which I found strange. What's even more weird is that at lower rpms(1000-2000) when taking off the clutch starts biting near the floor and fully grips soon after, like when the pedal is less than half way up. When I take off at higher rpms(about 3000) the clutch starts biting near the floor, but fully bites when the pedal is fully up, near the end of the travel. Would this mean that the clutch is almost toast? I tried flooring in when going up a hill at low/high gears and there is no clutch slip at all. Also I've been told by my mechanic that it needs all new engine mounts and I figured out as it's a FWD car that the engine might be moving so much at higher rpms affecting the clutch biting point. Could this be the case?
Tried to restore my headlights with polymerisation kit today. One headlight turned up amazing, but the other has a cloudy spot on it. Is there a way to save it?
I installed and wired up some new fog lights on a 2000 xj, and I'm getting no power to them. They're wired to a 4 leg relay, standard wiring the way you'll see every diagram, but no light on the switch or the lights themselves. Im going to check my grounds but is there anything obvious that I'm missing?
In my country, LED replacements for standard headlight bulbs on older cars were made legal earlier this year. In the past, these were usually chinese stuff of very questionable quality, which mostly blinded other drivers without much improvement to light output.
However, I just found out good brands like OSRAM, Philips etc have begun selling LED replacements for standard H4 bulbs etc. They are not exactly cheap though.
Are these any good, and can they be used without being an annoying asshat to other drivers? I drive a lot at night on rural highways with plenty of wildlife, and every bit of extra light is welcome.
My car has a dual setup of a combined high+low beam H4, and a high beam only H3. One possibilty would be to convert the H3 ones only, but I don't know how much good that would do.
Any idea what’s going on with our car? We had thought the engine seized up but are able to turn it on, have it run like this for a while, then it dies on its own.
Started this morning, 8:18am, was fine when I started her, pushed down on the brake just fine and went into reverse, then it started up with that weird whine. Recently replaced the water pump, but she’s been fine that whole time, so I don’t know what the hell is going on.
Cloth seats, 2020 crv. Various spills over the years, have water vacuumed a few times but still a musky smell when I go in that seems to disapate after I drive for a few minutes. Have changed the cabin filter recently too. Any ideas? I've read mixed things about ozone in terms of damaging plastic, not sure if there's any other effective treatment
Something has left this stain mark in the felt lined dash compartment of my Cadillac XT5. I don’t want to make it worse using a product that may itself leave a stain ring. Can anyone suggest how a detailed would deal with this…any product suggestions appreciated.
Hello, I have these not deep scratches. What product can you recommend to cover them up? I've read about the use of Meguiar's plastx in several places, but I don't know. I've read about Heat gun but I haven't used it yet and I don't dare. I'm afraid I'll make more trouble.
Hi :) , recently i started noticing that when idleling , my car's engine sometimes shakes a bit aggressively. The shaking is not constant but is happening is bursts. I also noticed that this happens after driving a bit , not instantly when starting up the car. The car is a 2000 golf MK4 1.9tdi engine code AHF
Also no other symptoms like loss of power is happening. Thank you :)
That's a screamer pipe! Someone's definitely tankered with this.

My car revs fluctuate with the cold engine. I have a Bmw 318i 2008 (N43b20a). What might be the problem? Could it be a vacuum leak? Where I should start looking?
I have a 1995 Honda Civic 1.4L Petrol (Gas)/LPG non-VTEC. Im thinking about doing a stage 1 remap, ita bone stock, no turbo, maybe fit a sport intake or cold air intake. Would there be any benefit of the remap, if so around how much?
I scratched the side of my car on a yellow pole in the parking garage and this was the result. What’s the best way to get the yellow paint marks out? Thanks!
I have a leaking brake master cylinder in my car. It has left a substantial puddle under my car. I don't plan to drive it except to the mechanic on Monday. If I add brake fluid can I drive it to the mechanic? It's about a 20 minute drive, I plan to use the manual setting so I can use engine braking on the way.
Also, this is the 3rd master cylinder to go bad in my car in 3 years. What could cause an issue like this? It's driving me crazy to keep having leaking brakes. It's a 2014 Subaru Outback.
Car squeeling only when turning right! Please help.
Hi, I have a 2018 Audi A4 2.0TDI. I have an issue where when I go around right hand corners/bends there is a slight squeal. You can barely hear it, only with windows down.
This doesn’t happen when turning left, my Audi being a B9 apparently doesn’t have power steering fluid (Electronic apparently) so I’m concerned what is making the noise. It’s at 80K miles.
Note: I did take to Audi for a free health check and they did say I need new Banana arm bushes? Im not sure what these are, however I would like to know from you experts, could this be the reason. Thank you in advance guys/gyals!
I've recently installed and hardwired a front and rear dash cam on my vehicle, but along the way I had a short in slot 15 of the passenger fuse box (driver's seat recline). This was fuse tapped with the 20A recliner fuse (battery power) and with a 15A dash cam fuse. (Too big I know, that's my bad).
The fuse tap's metal end touched the ground bolt and sparked, and the 15A fuse blew. I then replaced it with a 7.5A fuse and finished the dash cam install, which works fine now. The seat recliner also works.
However, the IMID screen no longer comes on at all. And the radio only comes on when the car is in accessory mode. When I go to turn the engine on the radio shuts off and stays off.
There's no other issues with the car as far as I can tell. I've checked the audio fuses in the passenger and under hood fuse box and they're all fine. Tried leaving battery disconnected for 20 minutes to see if it would reset but no luck.
Anybody have any ideas? Thank you
