I have a 2003 GMC Yukon XL 1500 4 WD. Ive been getting a loud bang ( like a hammer strike on the front frame) on occasion only after backing up and it happens after the truck moves forward a bit. You can almost feel the truck loading up and then it gives with a loud hammer like bang. Ive had a tech check the front end and do an alignment. I had thought it might be a brake hanging up.
View 2 RepliesLast year I did some major work on my 02. Painted it, new injectors, 38R, and once it was back together, the transmission went south in a month. Got a Ford reman HD4R100. Shortly after the install, when in reverse, the torque convertor would lock up when you stepped on the throttle. As soon as you let off the throttle, it would disengage. Thinking it was a tranny issue, got another one from Ford. This one has been in the truck for about 9 months. And it seemed fine until about a month ago. It started doing the torque convertor lockup thing in reverse like the last one, but not as often.
Then last weekend it did it every time I put it in reverse. Then yesterday, while pulling away from a traffic light, there was a loud bang, and lost power in the transmission. Once stopped, I found out it has manual 1st and 2nd, but nothing else. No drive, overdrive, or reverse. I personally believe something electrical led to these issues, and ultimately, the transmission failure. I know the truck is not stock, but I do not run it hard very much. When it went bang yesterday, I was not being hard on it. Where to look at what is causing this?
I have a 2002 bettle with about 150k on it. was running fine and one day while the wife was driving it she heard a loud pop/bang and it started missing and has low power. Starts fine just dosent have much power and is missing on one cylinder.

If I ease on the brakes ,no problem but if I hit the pedal there is a loud bang or clunk from underneath,sometimes front and sometimes in the back. It's as if the wheels stopped but the chassis went forward and back slightly. As long as I put the brakes on gradually there is no problem stopping.
When I come off the Interstate and leave the off ramp, the low side of the front end sounds as if there is no shock absorber ,doesn't matter which side is low,they both do it on the low side.
Intermittent problems.
Steering wheel turns and grinding,groaning noises from under the hood, not all the time.
Going over a speed bump in a parking lot causes the same noise I get exiting the Interstate.
Was driving down the highway when I heard a loud explosion.
View 9 RepliesMy phaeton's gearbox has progressively gotten worse.. When gearing down after accelerating I am regularly getting a very loud and aggressive bang rather than a smooth gear change, I believe the torque converter is on its way out or the transmission fluid is low.
What transmission fluid I should have in the Phaeton is it the 75w90? I want to try and top up the transmission fluid rather than getting the gearbox serviced as the waiting list in Dortsmund is too long and there is nobody nearby that I am aware of.

I was driving last winter when something bad happened. I was on the highway in 4H doing about 45mph (Really bad weather). Suddenly there was a loud bang, like a shotgun going off. The truck continued to run but it sounded like someone was beating my driveshaft with a metal pipe. There is no apparent damage but it grinds and bangs when it drives. The engine runs just fine. I limped it back home with the noises being constant only when its moving.
Ive got a 2013 Accent with 16,000km on it. It has an automatic transmission. The noise is when i pass from R to D, or P to D. It is an intermittent noise, so it does not do it all the time. But when it does, it makes a loud "bang" that can be easily heard and felt in the floor. Ive had it checked by the dealer, but it never does it when its in the shop.
I always let the idle go down before shifting into gear and even if i hold the brake hard to change gears it does it anyway. It doesnt matter if the trans is cold or hot. And no, i never change gears when the car is still rolling, always when i have stopped completely.
I was driving down the highway when I had this loud bang and twang, after inspecting the car I realized it was the left rear seat belt that was broken. The seat belt fails to retract and cannot be pulled. I'm guessing the retractor is the fault.
View 2 RepliesMy 2006 V6 has about 115k miles. I pulled up and parked the other day and with the car still running, heard a loud "bang" under the right passenger side, and then the compressor wouldn't stop, even with the keys out of the ignition...it was still running an hour later when the flatbed took her away to the dealer.
The car was rear-ended 4 years ago and the back hatch/glass, which operates from the air suspension system, hasn't been able to hold itself up in several years. So there probably really is a real problem with the air system.
Here are questions initial questions I have.
1. From what I've read, it is common that a leak elsewhere in the system caused the compressor to eventually fail. The dealer is telling me that the compressor "blew apart inside" and that it needs to be replaced. Is this reasonable given that the compressor was still audibly operating an hour later?
2. The dealer is telling me that they cannot troubleshoot the rest of the air suspension system without me buying the compressor first. Is this a reasonable approach and level of competence? The service went on to say "We don't see many of these." Should I be worry? I am also concerned that I've read stories about dealer service departments who didn't know/didn't offer up that components of the suspension system can be replaced without the whole, very expensive unit.
3. The SUV was in the dealer 3 days prior for a new drive shaft and some electrical repair in the headlight which included the fuses blowing several times. Could there be any connection or does this sound like coincidence? Any thing I should ask them to protect my interests.
Just a hour ago, driving along about 45, then I hear a loud bang and my truck quits. I get off the road and it won't even turn over. I had a friend tow it back to the barracks and put a socket and breaker bar on the crank and can't move it. All the fluids are fine. Possible seized up? The thing was running great as always then boom. Nothing! It's a 06' F150, 5.4, 97K on it.
View 6 RepliesI pulled the EX into the driveway today and as soon I put it in park as I was turning it off there was a loud pop / bang noise somewhere in the front. My husband was already taking it to get new tires so I told him about it and he left to go get the new tires. He said he right away noticed it pulling real bad to the right (I did not notice this and I am VERY in tune with my truck). When he got to the tire place they brought out a big bolt they found in one of the front tires. He said it drove fine all the way home after he got the tires put on. I get in it to run an errand after he brings it back and immediately notice it rides lower. We had the exact same tires put on it that we always do. I also notice a rattle noise and feeling under my left foot that is sitting on the floor as I am driving. I wonder if I broke a shock or something but he looked and says he can't see anything broken. I have a 9 hour trip to go on with my children soon so needless to say I am a little concerned.

View 16 RepliesLately almost every morning my brakes have been seized. After releasing the parking brake the car won't budge without a bit of gas and a loud BANG from all four wheels as they become unstuck. And I don't mean a small bang, it sounds like someone whacked the wheel with a sledgehammer. It has been cold, snowy, icy, wet, and very salty here lately, but the car is parked in an underground garage overnight where the temperature is above freezing.
After becoming unstuck the brakes are noisy and very rough. They'll also re-seize at each stoplight, but with just a small bang. This slowly gets better as I use them, until the next time. Is this normal?
I can't imagine it's good for the health of the brakes for this to be happening. I've heard of this happening if a car is left sitting in wet conditions for a couple weeks, but only after 12 hours, and again at each light? I also had the dealer take apart and clean the brakes about 4 months ago.
2002 Excursion 4x4. While applying my emergency brake today I heard a loud bang. Now, the parking brake won't come up when I pull the parking brake release. Also, the noise is driving me crazy. Is there a way to release the pedal until I can get the cable replaced?
View 1 RepliesI have a '06 Mercury Mountaineer, right over 100,000 miles. For the past few months the car has started to make a sound and even produce an "clunk" that I can feel when I am slowing down to come to a stop. It only happens when I slow down to around 3-4mph or slower. The transmission has only around 10,000 miles on it. What could be causing this?
View 9 Replies2008 Passat 2.0T auto, started occasionally shifting with a loud bang into and out of park, and from forward into reverse and reverse into forward. No MIL, pending transmission communications error code. Would accelerate very poorly up until about 30mph and then accelerate normally. Shutting the car off and then restarting would usually clear up the symptoms. Started happening about once a week over a 3 week period, and then started happening about about every other day. With it happening more often, had an opportunity to experiment a little, and by shifting into sport mode (which causes the MFD to display the gear that the transmission is in) noticed that the car was not shifting into 1st to 3rd gear, but starting off in 4th. With that and the rough shifts in and out of park, I thought that it was probably transmission related,
With a tranny being $$$$ and the battery being 4 years old, and relatively cheap to replace, I decided to play the long shot and see if a possibly weak battery was causing an electrical problem in the transmission. The battery checked out OK at a couple of places, but decided to give it a shot and replace it anyway.
Installed the new battery (Bosch from Pep Boys $109) and had every warning light on the dash go on with the first restart, along with a return of the harsh shift out of park problem. Shut the car off, turned it back on, drove five miles, all the warning lights went out, and no return of the transmission problem after 5+ months and 10K miles.
Just a heads up - if your battery is 4+ years old, and you are getting any odd problems that could in any way possibly be related to the electrical system - which includes just about every system on our cars - consider going for a new battery. Worked for me.
I have a 2000 Jeep Cherokee Classic with 214,000 miles on it. Ok......this hasn't happen too often, but scares the CRAP outta me when it does.The other day, it happened twice. Traveling on the highway, 65 - 70 MPH, the car suddenly jolts with a loud BANG!I've had the transmission fluid flushed.Each time I go in for service at my local garage, I have them check ALL the fluids. They never find anything. And are at a loss as to what it could be. They've dropped the pan and found nothing wrong with the transmission. No metal in the fluid. They've check the rear diff. Still nothing. I've gone about a year without the issue until this past Monday when it happened twice. I'm a little paranoid to go faster than 60 - 65 right now.

Can be in cruise or not, tow/haul or not, but need to be pulling a decent hill with 7k+ trailer. Running level with air bags. Regardless of speed, cruising at 50, 58, or 65, beginning incline and turbo boost builds normally to maintain speed to the point when it needs to downshift. BAM!!, not just a clunk, 90% of the time- scares the hell out of me. I can make it do it on an incline empty, but it it difficult. If because initial speed is 50ish, a second downshift to 4th may be needed. A bang only 50% of the time.
No codes.
Regardless of the degree incline, (toughest in the NC/KY areas is 6-7% grade, can avoid harsh shift by backing off on throttle and manually downshifting to 5th or 4th, depending upon speed.
Can "make" it do it on level terrain with 7k trailer if I slowly back off throttle and slow from 65 to 50 or so and punch it, but not too hard. Too hard and it goes to 4th, usually with just a modest clunk. Just right and I get 5th with a loud, and I mean loud BAM. Even the tech was impressed.
Afraid to hook up my 17k 5er and take off for the next 3 months, which is the reason I bought the truck to replace my 11...
Carrier bearing has grease coming out of it (400k on various duallies and never seen this), but dealer says not an issue.
Ford told dealer that it had no idea, and advised tech to do a lot of pin point electrical testing and everything checks out. Next stop is the inner workings of transmission.
I have been without it and work for 3 days because of backlog. Running two day load tomorrow, then back in for tranny work.
Bought a 2012 Azera a couple of weeks ago. When the engine is cold and I shift into reverse there's a loud bang and the whole car shakes. Feels as if I've been run into, or the transmission is going to fall out. I have also noticed some delayed upshifting (doesn't accelerate for a second but then really takes off). My 2007 Sonata did that a little, so I thought maybe it was a Hyundai thing, but maybe not.
My main concern is the BANG into reverse. The dealer said they can't get me in for several days, and that they don't have loaners, but they "might" be able to get me something to drive while they look at it. Honestly, the service guy sounded skeptical, and I guess I imagined a little better/faster response for such a new car. I'm almost afraid to drive it right now, the bang is so violent.
I'm pretty upset about this, it's my first really nice car. Has some sort of transmission issue with a new Hyundai? Anything in particular I should look for, say, etc.?
1999MB 320 Automatic trans .... Stopped at a light went to start heard a loud bang car became motionless? Trans has 60k and never a shifting issue.
