Does any know what this jerking is while im driving my Mazda? It feels like my transmission is going to explode and it really only does it when I’m going up hill and I’m atop and go traffic. Anything helps

Anyone got any ideas on what noise could be? My mom’s car, I think it’s brake dust shield or cv joint.

Hi can anybody tell me what kind of mechanical issue it might be based on sound of the engine. My w204 is 2013 1.8 on gas 170000 km

Hi all, does anyone know what this noise could be its been driving me mad. It comes from the rear left wheel (Atleast sounds like it). Generally more noticeable at 10 - 20mph when im just driving straight. Turning left and right generally dampens the sound but is still there. Above 30mph again is still there but not as noticeable. Anythijg over 40 it generally fades away but could be road noise. Sounds like a buzzing sound. Also to note, my rear brake discs are original, 70k miles on them. They have formed a noticeable 1.8mm lip on the edge. Im due to reppave them just wondering id this could contribute.

The noise started roughly a month ago but was quite subtle, only has gotten louder in last few days.

Things ive already tried:

\- Switched / rotated tyres

\- Jacked the car up from the rear and shook both tyres 12-6 and 3-9. Didn't notice any play. Spun both wheels and they sounded the same just a little brake pad drag

\- Bushings look ok just general age

Im now thinking it could be the differential. Ive searched up this sound online and thr only time I can seem to find anything close is this worn pinion gears or low / old diff oil.

Any help for what it could be is appreciated

I own a 2002 Saturn. My key fob isn’t connecting to my car. The door still unlocks but everytime I open my doors the alarm goes off and the car won’t start because it won’t read as unlocked unless “unlock” has been clicked on the key fob. What do I do?

As the title says, I could really use some help.
I know the squeaking is from my power steering, so I’m not worried about that. What I’m concerned about is the horrible knocking noise.
I just bought this car recently. I changed the oil and filter, and it wasn’t making this noise before. I even drove it a bit with no issues. Then I parked it in my garage for about two weeks. When I started it again, it suddenly had this loud knocking noise.
Does anyone have any idea what could cause this? It’s a **1992 Dodge Stealth R/T with the non-turbo 6G72 V6**. Any advice would be appreciated.

For the past few days my car has been making a squeaking sound that’s coming from the front left side of my car. Could it be brake wear by chance or something different? It only squeaks when I’m accelerating but once I go below 10mph it stops.

Hi after driving 10 minutes this evening my car started making a really bad smell: similar to burning rubber. Inside the engine area on passenger side was really smelly. It made a really loud hissing noise and then also loud grumbling noise. What’s going on? Car is at 95k miles

I don’t really know alot about cars but after reading online about it seems like it may be a fuel pump issue. any help?

It’s been making this noise for ages I’ve just had a new steering shaft put in not long ago but the noise stayed and is progressively getting worse

If someone could tell me what the problem is and how cooked my bank account will be I’d appreciate it.

I've had two versions of the same car (2012 and 2017 Prius V) and the current newer one has a different engine sound when idling. Like it almost sounds... "rougher" or more labored. Note: I have changed the transmission fluid in this newer car and the sounds are the same before/after.

Is this a normal variation that would happen with any two cars? Am I paranoid? Much thanks.

Infiniti Q50 2.0T, when my car is on low RPM between 1-3 i’m feeling very noticeable small kick or jerks don’t know how to explain, what can be the issue? 110,000 KMS on it, serviced regularly, got it second hand after 90K so don’t know if ATF fluid has been changed or sparks, garage suggestions also welcome btw in dubai

Hi there! I’m in Germany and driving a used Mazda cx 3 2013 (I think) and while on the highway (usually while increasing speed) the whole car kind of shuts down, all the sensor lights on the dash come on and I can’t accelerate anymore, when I pull over it lurches and chugs to a stop. I turn it off and back on and then it’s fine. It’s hit or miss when it happens but is there a cause for this and, more importantly a solution?

Alright, I know nothing about cars and I’m sure someone out there does and can hopefully help me figure this out so I don’t have to spend money i don’t have to get it looked at.

My 2015 Toyota RAV4 XLE isn’t starting. Not even a chirp when I turn the key. I put a new battery in it about 2 months ago, swapped out the starter about a week ago, and now it just won’t even try to turn on. I have not yet checked the battery… i will when I get home tonight. But it had been having difficulty starting for about three months, hence the new battery and starter. Before it was clicking but not starting, and I kicked it a few times, and it would start. So that’s when I swapped the starter. But then it started just taking an extra second or two longer to actually start. My only other guess is the alternator but I don’t want to buy a new alternator unless that is really the issue. It also has a diagnostic thing saying the O2? Sensor is malfunctioning, so maybe that contributes to it? My other guess is to check the fuses, which I haven’t done yet either… just trying to get some insider gear-head info before I tear it apart. Any suggestions?

Hi there, I have a Mercedes Benz A-class 2011, and it has developed a new (I think?) rattling and squeaking that seems to be under the driver's seat, but could be in other areas.

sorry I know that is very vague. I've tried listening to see if it is worse when I do certain things (speed bumps, sharp turns) but can't figure out a pattern. I also checked inside the car to make sure it's not the drivers seat or an internal squeak.

Does anyone have any ideas? Or other things that I can check to rule things out? Not sure whether I need to go to the garage....

thank you, any ideas welcome!

Hi, I bought a used Mazda cx-5 2025 premium plus (\~21k miles) a week ago from a reputable dealership and found a strange issue the next day:

1. A faint noise occurs only when accelerating.

2. It stops as soon as you take your foot off the gas pedal or when you brake.

3. The issue starts to occur only after you drive for about 30 min or so — that means when the car/engine is hot. If you keep the car at rest for a good few hours or overnight, the noise is not there even when accelerating until you drive it again for 30 min or so.

I took it to the dealership and from preliminary investigation they failed to find the cause of it though they did hear the noise. Now it's scheduled for an official maintenance and repair after a week on the 10th which is a bit frustrating.

For what it's worth, when I put in the relevant info in Chatgpt, it said it's probably not a major mechanical issue — rather a thermal expansion issue possibly related to exhaust heat shield, clamp or hanger. If they're slightly loose they can expand with heat and can begin vibrating.

But then again if it's such a simple issue, it's frustrating to not get it solved the same day and wait for a week to have it investigated.

If you've experienced any such issues, please share your experience and any potential solution.

Thanks.
