Content Guidelines

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. *

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.

2015 Ram 2500 6.4 Hemi Intermittent Start/Idle/Run Issue

I have a 2015 Ram 2500 crew cab laramie 4x4 that has been having intermittent running issues. Currently have 81,XXX miles on it and over the last two weeks it has randomly started to have choppy idle, while searching for rpms, and then stalls out. This has mostly happened when parked and only one time where I was driving down the road where it died and could not get it restarted. There were no codes when it stalled but the service electronic throttle control came on the dash once.  I had it towed to the dealer after I went through trying to find connection or other issues I am familiar with. Once the dealer actually looked at it, sitting for 4 days, it fired right up but ran "a little" rough. Then it started running just fine. The only thing the dealership found was that it threw a code for bank 1 and 2 02 sensor out of range and it lost communication once to pcm. After them "looking" at it for 3 more days, they could not find any issues and it was running fine. They said they checked all the connections for main wiring harness and could not find anything. I drove it home with no issues and drove it several times over the next week. The weather was around 20 to 40 degrees with no precipitation while all this was going on.

 

Once home, I did several checks for grounds and wiring harness connections at the pcm, sensors, etc., with finding nothing loose or issues. I opened up the fuse panel and made sure everything was secure down for fuses and harness. I did checks of hoses, etc. for any kind of vacuum leaks, and found nothing. I tightened down the intake 8mm bolts, which I have done before, and nothing was overly loose. I decided to go ahead and change out the front 02 sensors myself ,based on mileage and low cost. It seemed to run just fine.  I cleaned the throttle body as it had some build up and a little bit of oil. I threw in a standard paper air filter to rule out any kind of oil interference that some could say coming from the standard airbox K&N filter. The K&N has been in there since 3,000 miles and cleaned every 20K. I found no miss fires logged on the scan tool while watching live data and nothing stored.

 

After not driving it for two days, I went out to run an errand. It started fine but then went back into a choppy idle and then died out after about 20 seconds of searching for an rpm. It started right back up but then died. You could smell it running rich and I also smelled a hint of oil. I looked at connections for maf, map, iat, throttlebody, battery, etc. and found nothing. Throttle body checked clean, no oil on the back or build up hindering operation. I pulled the connection to the MAF and it popped the service throttle control error on the dash. I also pulled the MAP sensor and it lit the CEL for a MAP sensor out of range and it seemed to start to smooth out the idle.  I jumped back in, shut it off and started it up again, and now running fine. I had left both the MAF and MAP unhooked when restarted so I plugged them back in and still runs fine. I cleared the codes I took it on a run and it is not in limp mode and idles fine.  Battery is full charged, full of fuel, 35 degree weather no precipitation. I turned off the heat / defroster when it started to choppy and nothing changed. No missfires registered on scan tool.

 

Any ideas on what else I can look at or missing for this intermittent?

 

Truck has always ran smooth until at 72K, about 6 months ago,  the MPG started to drop from just below 15mpg to 12.5 to 13 all the time. One day I left to go to work and it seemed like it was going in and out of limp mode after I got a mile away from my house. It was a standard warm summer day. It cleared it self up as I was turning around to head back home.  I checked and there were no codes, no misfires, or nothing else as I backed into my garage. The service throttle control did not show up at that time. I shut it off and went under to see if I see anything or find anything else. I started it back up and it was the choppy idle and then stalled out. I could get it started but loopy idle and die out. I took a shot, based on something I experienced with another 1500 with the 5.7 hemi, and changed out the MAP sensor, MAF sensor, and PCV. As soon I did that, it started and ran fine. I decided to change out the plugs at that time too. It had been running fine until this happened at 80K

 

I appreciate any ideas.

ChargePoint in trouble?

My home ChargePoint Ev charger stopped working, called the company it was out of the 3 yr warranty 2 months ago, they said it was stuck in a ‘bootloop’ and I would have to replace the whole thing. He couldn’t help me as they weren’t selling any chargers at the moment. The store is offline too. Has the company gone belly up and they’re switching off the technology after warranty’s expire??

Cracked rim? Is this a concern?

Disclaimer: I dont know too much about cars so this may be a dumb question. But i just notice that its cracked here and I don't think it happened recently. Is that bad for the tire and should I get the rim replaced?

Opel Corsa D 2011 1.4 check engine light issue

So as title states.. I have a check engine light on my Corsa D 2011. I just bought this car second hand, I drove it 1000km on a small road trip, this is my second car, I havnt been driving for long, I love the car, it’s great. Faster than my old car, more modern etc etc.

But, during the trip the check engine light came on, it was on for a few days so I checked the oil level added some in, the coolant doesn’t have a “min max” level so I don’t know if that’s the issue, was about to get it checked out by a mechanic, but then it turned off. Thank god I thought. Then a day later it came back on and now I’ve just driven it again and it’s off again 😂

It’s yellow, so not red or blinking. And my trusted mechanic is away on holiday until next week.

I ALSO noticed that there is a small ticking noise coming from the right front end of the car everytime I’m in low gear and Accelerate (it gets faster as I accelerate) and when I start driving I have to really give it more revs than I would have in another car to make it not feel like I’m about to stall.

TIA

Is it normal if the turbo charger has a sound?

I have a hyundai i30 1.6 crdi (diesel). If the engine warms up, there is a humming whistling? sound from the direction of the turbo. Its not very loud, but it’s definitely hearable, a bit annoying. Its hearable in the range of 1000-1500 revs. Above that I dont hear it, maybe the engine’s sound suppresses it. My question is, is it normal? I sat in a few other type of cars with turbo, but I definitely didnt hear anything like that in any of them. I attached a short video about it. Should I visit a mechanic? Thanks.

Full coverage on a rebuilt title

I am considering getting full coverage on my car. It’s a 15 ford fiesta. I paid about 5k for it. My insurance said full coverage would be an extra 70 dollars a month. Not sure how much they would pay out or if it’s worth it.

Worth fixing?

I have a 1999 Lexus ls400 (226k miles). My dad damaged the keys, and now it’s just cranking. My buddy installed a new fuel pump and a new ecu and gave me a new key. Still cranks with the new key. Worth fixing it up? Car been breaking down as soon as I fix it. (First issue was transmission, got that fixed, second was a coolant leak, fixed it, next was steering rods, fixed it) idk if it’s worth putting more money into this car

Lost Key Fob but Not Key

I lost the only key fob I have for my car, but not the key that goes inside it. It is a 2010 Nissan murano, push to start. So I can unlock the car with the key, but need the fob to start it. If I order a replacement fob, can I reprogram myself or have aaa do it for me? I’ve looked it up online and I’m getting mixed suggestions. All the answers were for if someone lost the key and fob. I just lost the fob. I heard you can maybe reprogram yourself?

Traction ligh on after passenger side arm control was replaced

My Nissan Sentra 2013 had arm control replaced by a small mechanic shop and when they finished working on it they called me to pick it up, I went there and as soon as I started the car traction light was on, they red the code as “steering angle sensor faulty” mechanic claims he had nothing to do with it, is that possible?

Carpet “qualities”

More or less just want advice here..

Found a website i can finally purchase a carpet for my truck from, but they allow me different options.

In terms of material, they ask if i want: plush cut, ultra plush cut or neon plush cut (bright colors)

Now im currently not overly worried about what color im going for, but im worried about the plush.

I live in canada, where during the colder months it it always wet, dirty, sandy, salt everywhere.. point being i dont want to ruin a brand new carpet.

Question: whats the difference between plush cut & ultra plush cut?

Steering wheel knocking noise

I get this wierd clunking noise when I kinda wobble the steering wheel, could anyone please tell me what it means? I also get the same noise even when the car is turned on, but you wouldn’t be able to hear in when I take a video, so this is why I was wobbling the steering wheel when the car is off

2009 Mazda 6 hatchback interior lights

None of thr interior lights won't turn on in the car. One rainy day something happened to thr battery and it turned on for a split second after never turning on again. My car does have a bit of rust on the and the doors. I also have a sunroof. Fuses are all ok which is the main concern. I'm thinking it might just be the switches which are so rusted they can't give a signal I have a whole new switch module which I will replace.

What do I do?

Car also has some transmission issues and a CEL and dsc ( its probably some sensors and an o2 sensor but thats not an issue for now )

What issues should I expect from a 2010 Acura TL (SH-AWD) with a mileage of only 150 miles?

I'll stick to the important bits to keep this short and forward.

As mentioned, car's mileage is around 150 miles. Owner says car's been sitting in the garage all this time.

A huge point to take into consideration is, he's never changed the oil ever since he purchased it.

Please first explain the LIKELY issues I might face with this car if I decide to buy it. Then add the lesser likely issues.

And most importantly, please, give me an overview of how easy or hard it is to resolve the major likely issues associated with this car, and it would mean the world to me if you gave practical ideas and options of these types of fixes.

FWIW, car's listed for $8K.

And I've test driven it around the neighbourhood and on a few kilometres of highway, and didn't notice anything wrong with the drive (it was responsive and handled well actually!), but I'm no expert obviously.

Please share your knowledge with me. And thank you in advance, everyone.

How to turn off folding mirrors?

I am driving Ford Kuga, 2018 and due to this cold weather if mirrors are frozen, it could easily break the motor inside.

I was thinking to turn off the folding mirrors but i cannot find the option in settings and there is no button for on/off.
Does anyone have a solution here?

Possible belt problem

I’ve had a recent problem with my 2005 hilux n70 where when I accelerate there will be a loud noise until I reach 60-75kph and I wanted to see if it’s more likely to be a timing belt or an alternator belt, I’m having no problems with how my cars runs and starts so I’m leaning towards it being the t belt

Window won’t close

I rolled down the windows in my car and one of the back ones won’t roll up again. It’s midnight where I am right now so I’m thinking of leaving it and fixing it in the morning.

I managed to get it halfway up and I live in a decent neighborhood so I’m not too worried about theft. However, I’m wondering if it’s safe to do this due to environmental factors. It’s only for tonight so I’m thinking it should be fine but it also gets cold enough but moisture and ice to form on the windows so I’m not too sure.

Any advice would be appreciated

Lost the 1 key for car

I'm seriously upset and stressed out rn I've spent the last almost 3 days now searching EVERYWHERE for my keys and no luck it's a 02 Lexus es300 I bought used and only came with one key I know it's expensive because it's a Lexus alone which is dumb but what would be the easiest cheapest route of getting another made I'm broke and not trying to spend a couple hundred. I had a so called "friend" over and sadly she is a thief and stole a few other items,swears she doesn't have them. I know I do have severe ADHD & have lost keys before but have literally searched thoroughly for the best 3 days and can't find them so just trying to figure out best ,& more importantly cheapest option.Yes ,I understand I'm going to have to spend $ just trying to do it as little and cheap as possible

Lotus experience!!

I got a chance to ride in a Lotus recently, it felt pretty different from other cars. It’s not about speed or fancy features, but how it drives. The car responds so quickly to every little movement, and you really feel connected to the road. It’s one of those experiences that’s hard to describe, but definitely stands out...

Considering this vehicle at $11k.

Do you recommend? Is there anything I should be looking out for? I'd like to have my mechanic inspect it prior to purchase... what should I ask him to look closely at?

Thank you.
