"Sometimes" when I start my car (2015 2.4L GL base) there is a clunk like something is disengaging or engaging i.e., torque converter or transmission.......??
View 4 RepliesWhenever I park on an incline whether it's upward or downward the car seems to roll about an inch or so after engaging the parking brake and then taking my foot slowly off the brakes. When I engage the parking brake I have the transmission set in neutral so the weight of the car doesn't put stress on it.
View 26 RepliesMy '05 F150 (92,000 mi) 4 wheel seems like it is engaging and disengaging when activated. Makes a clunking sound on light acceleration then quits when I back off the gas. Not sure if it is engaged then or not. I noticed this on a gravel road when I had turned 4x4 on to distribute oil around the system since I had not used it in a while. What it might be and if it is any easy fix or a trip to the shop.

View 3 RepliesI have an '05 Pathfinder w/ 93k miles. Recently noticed a uneven feel in the power steering, most noticeable at slower (less than 30mph) speeds. Feels like the power steering pump is intermittently engaging/disengaging. As I turn the steering wheel I feel random "tight" or "hard" spots in the steering. Similar to what you would feel if the wheel was against a curb and you were trying to turn into it. Doesn't make any appreciable noise, but can just feel it in the steering wheel.Checked power steering fluid, no issue. Replaced power steering pump, had no effect. Power-flushed the power steering system, had no effect.Oh - and my wife says she hasn't hit any large rocks, logs, or potholes recently!
View 5 RepliesSo I brought the Sonata home and she sat in the garage for 5 days as I was traveling. Then when I got back, I was so eager to take her for a drive. At this point she only had 72 miles on the Odometer. When I started her up, I thought the engine sounded rougher and louder than usual. My other car is a Turbo Diesel and that does not make this loud a clatter. After a few minutes of idling and driving, the engine quietened down quite a bit.
Video of the sound at cold start up.
I own a 2002 Chev. small blazer with 4 wheel drive available. Largest V-6 available. There is a clunk sound I can hear and feel as this vehicle is shifting OUT of 4 wheel into 2 wheel drive. Going from 2 to 4 wheel drive is perfect. First mechanic (test drove alone) said he would have to tear apart the front transfer case to determine fault. 2nd mechanic (with me along) did power brake slow turns in parking lot. Said the electric shifter was bad and would have to tear apart the transfer case also. Neither mechanic put the vehicle up on a hoist.
View 2 RepliesI have a 2015 Sonata Sport 2.0T with less than 7k miles on it. I commute about 14 miles to work. During this drive, I hear a clunk/thud in the undercarriage that occurs usually 2 or 3 times each drive. It sounds like it might be coming from the wheel well. Originally I thought my tires were picking up rocks on the road and throwing them up into the wheel well. If any of you are familiar with the sound of dried mud releasing from a tire or the wheel well while driving a truck, this sound is very similar. It might just be me, but I feel like it is occurring while turning the wheel/straightening it out after a turn. Today it happened while changing lanes twice, and once taking a right hand turn semi-quickly at a green light. I know that I am not running anything over that is visible while driving.
View 4 RepliesHad an odd event this morning on my drive into work. Put the cruise control on at about 75 mph, after several mins came up to traffic and as I pressed the brake the car began to speed up and the engine revved up, I had to press the cancel button on the cruise control to disengage it. Immediately after disengaging it, the ESC came on solid. Once at work, I re-started the car without issue and the ESC light went off. Didn't try the cruise control again on the drive in.
2011 Sonata Limited with approx. 55K. Bought new in Feb in 2010. I have had the brake stop recall performed several years ago.
I have been reluctant to post another clunking thread because it's nearly impossible to accurately describe what is happening. But I have reached by breaking point and I wanted a few opinions before I take it into the dealer. I am still under powertrain warranty, but I want to be confident I am not wasting mine and the dealers time if I am just missing something easy. I also know dealers don't always take clunks seriously so I want to pinpoint it first.
Symptoms : Car has 50k miles. I am the original owner.
From a stop, when getting the car rolling moderately aggressively there is a clunk/pop noise from the car. I can slightly feel it in the pedals and it is fairly loud. Almost like a distant hammer and nail pounding. It's a single clunk, with sometimes a double "pop pop". It's noticeable even with the radio turned up a little. If you are smooth on the throttle it doesn't make the noise. It seems random, like something is hitting something which only happens under certain weight shifts.
It sounds like it's from the rear and the front. It seems to switch. But honestly I am not confident either way. Where it is. It is silent on turns, bumps, speed bumps, driveway, etc. I don't think it's the suspension. It is not a clicking/tapping, only a single clunk or knock.
It also happens in 1st/2nd in stop and go traffic. If you leave it in 1st and the traffic is moving from say 8-15mph where you don't need to use the clutch it will clunk during on/off throttle. Anything above ~30mph I haven't been able to replicate the noise with on/off throttle.
It also does it if I downshift when coming to a stop and don't rev match. Say you are slowing down and you go from 4th, 3rd, then 2nd, let the clutch out and it rev matches up to ~3,000rpm which causes the weight to shift forward....clunk! It is not easy to replicate which is another reason I am slow to bring it to the dealer until I pinpoint it.
Things I have tried:
- Subframe bolt torque check. Installed ECS spacer/bolt kit anyway.
- Sway bar links are tight, or at least they didn't budge at all.
- Adjusted the rear hatch a million different ways as it was making a similar noise earlier.
- Spare tire tightened, tools removed
- Rear seats up/down/mix/seat belts fastened, etc.
I was only able to locate one motor mount? Where they are. Seems fine. Dogbone seems fine, again hard to tell.
Suspect:
I have VWR springs, but I am 90% sure this started happening right before I had them installed. I did the rears myself, a well known shop did the front. I noticed the noise maybe 2k before the springs were installed.
Clutch linkage somewhere - I had issues with my transmission (early build). The clutch was replaced at 7k. I've always had a very loud flywheel and a grinding feeling in the pedal. Maybe the shifter linkage is hitting something? I have little experience with VW's so I am still learning and don't know what to check.
My rear harmonic balancer is cracking like everyone else. I have no vibrations yet and I don't see how it could be causing a clunk in the current state. Maybe a motor mount is bad that I cant see? It feels like something is loose in the drivetrain.
I have a 2015 with 10k miles on it and every once and a while, when I come to a complete stop and shift into reverse, I take my foot off of the brake pedal and the car will sit there for up to 5 seconds. Then, it kicks in and starts rolling backwards. This has happened 6 times now. Giving it gas doesn't seem to work along. I took it to the dealer today for it's 10k service, and they cannot find anything wrong with it. There are no codes in the computer, the fluid is where it should be, and they think the Neuspeed Power Module has something to do with it. I told them it happened before I installed that piece. I can assure you I am not racing in reverse.
View 7 RepliesI've noticed an intermittent clunk which occurs when engaging the hydraulics brakes during reverse maneuvers. It happens with anything from very light to very heavy brake force and typically will happen before driving very far (backing out of driveway, out of parking spot, etc) but does not happen after driving (backing INTO driveway or parking spot). This has been occurring for a while now with no other symptoms (other than some shudder during take off which I attribute to a sloppy transmission bushing).
Front brakes were in great shape when I r&r them a while back to turn the rotors, didn't pull the rears apart but they look good, and I don't have any brake vibrations or issues when moving forward. I can't rule out a driveline clunk or suspension clunk either but the u-joints don't have any slop in them and no squirrely handling issues either.
My 4x4 on my 2000 model f350 will not engage. The light works, comes on briefly on startup of the engine. When I flip the switch nothing happens. When I jumper the relays nothing happens. I do not have the factory hubs, they r warn hubs and the vacuum line to them is capped off. How to figure this out on why the 4x4 will not engage?
View 13 RepliesLast night when I started my car before heading home from work I noticed that the engine clunked a couple of times, as if it were slowly combustion or back firing in two cylinders. The car started up fine; however, I've never heard the engine do that before. I don't know if it is because it has been cold up here the last few days (-12C (10F) day time highs) or if there's something else wrong. My EGT has just under 60,000km (37,200mi).
View 2 RepliesThe last couple of weeks a new clunk has appeared on my F350, 6.2 CC LB FX4. If I've been parked for a while, when I drive off, within the first 30 yards or so there's a clunk. Seems worse when I've turned sharply out of a parking spot. Sounds like the rear diff or drivetrain... I have a locking rear diff. Is this engaged or disengaged while "at rest"? Could it be that its slow to unlock when I start?
View 13 RepliesI'm having trouble with my a/c clutch not engaging now for about 4 days. I believe I have narrowed it down to the field coil. I checked and I am getting 14 volts at the wire that plugs into the compressor. Auto a/c function will not turn on the a/c compressor light on the dash, but will turn on when manually pushed. When this first started, the radiator fan would kick on but spin slowly and now does not turn on at all when engaging a/c.
Per an older thread I checked the resistance at the a/c relay, though it did not tell me which pin(s). The only readings in ohms I could find from the a/c relay junction in the engine fuse box said 69-76 ohms, but I am unsure whether I am reading the correct wires or the correct way. Facing the front of the car, I am getting the above ohm reading from the bottom right pin to ground. Which pin is the correct one to test?
I am currently thinking the a/c clutch field coil is bad, but it stumps me that the radiator fan will not kick on either now.
Background of car : PO wrecked car, damaging the front end. I bought the car and fixed it up. A/C Pulley was replaced due to bent flange where serpentine belt travels. Also brand new radiator fan and replaced other seemingly non-related items to this issue.
My RC just hit 22k miles a couple of days ago. This morning when I went to turn on my car, it took a couple of extra cranks for the car to turn on. I am dropping the car off tomorrow at Lexus.
View 2 RepliesI have had this happen the last couple times I use my car in the cold. It has been around 25-30 F and when I pull out of my driveway the first time/maybe second time I touch the brakes it forcefully stops and feels as though only the front brakes are engaging. As I drive the car that trip it has yet to happen and the brakes preform normally. I am not used to disk brakes and I am thinking it is maybe that? The only other thing I could think of is that the brakes need to warm up a bit and pressing them still cold illicit that jerked response. I have read through a number of threads on brakes and I cannot seem to find this happening.
View 4 RepliesWhen backing out of same parking spot, I always hear a clunk, clunk, clunk, noise in the front while turning the steering while back in the fixed position. I have heard this noise in the past but did not think any thing of it.
It's hard reproduce this noise, it seems to only be happening when backing out and turning the steering wheel. Car only has a little over one thousand miles.
I took my car in to get this checked out, but they say they can't hear it.
Sometimes when I turn my car on right after I turn it on, there's a loud humming sound like a compressor or something is kicking on and it's not fully engaging. And it only makes the sound for maybe 3-5 secs. Sometimes it won't happen when I turn the car on, but when I'm driving and I let off the gas and go to touch the brakes, it'll start.
The best I can describe it is a 'hum'...but it's loud, and I can feel it as if it's near the gas pedal right behind the firewall.
Dealer thought maybe it was the ABS switch testing itself..but they could never reproduce....I got in after they replaced my rims and checked it...and it did it 4 times when I started it, then turned it off. He came out to check, and it was almost as if you couldnt hear it outside of the car.
So, what the sound might be...I can't reproduce it anytime I'm there. Figures...... but I hear it almost daily. He put some foam tape on the firewall behind the gas lines saying the 'pulsing' from them might be doing it...but it did it again this morning.
I get a pop or a clunk from the front drivers side when I brake. It used to happen less often but I took it to the dealer to fix and they lubricated the caliper pins and now it happens frequently. I've read that the Sonata has some issues with the calipers. I would like to repair it and lubing the calipers made it worse.
