I just bought a 2012 C- 3 ... Today it's been very cold here (Chicago) the first day it's been this cold since I bought the car last month. Anyway as I'm driving every now and then there's a very loud thump on the roof like the wind is pushing the roof in. It seems to happen as bursts of wind hit the car.
View 2 RepliesIf I drive at higher speeds (anything above 40mph) I get an unusual wind vibration noise when the roof is fully retracted. If I roll it forward an inch or two it seems fine. Seems like a bit of a design flaw.
View 10 RepliesPurchased an 09 Touring and so far enjoying the driving experience. Getting 42/43MPG with mostly short trips. However, I have noticed one thing unusual. Not sure if I should be concerned or if this is a normal thing. I am a rideshare driver, and whenever a group of people get out and I accelerate away from them, I hear a pretty loud thump sound. This happens usually when a group of 3 or more exits and often does not happen when one or two people exit the vehicle.

View 1 RepliesAs it is, my roof racks are separated, as if they were going to carry skis or something else on them. I notice a typical wind noise at highways speeds, not unpleasant, but I wonder if I put them together at the rear, or took them off altogether, it would make much difference. Also, as I take off on cold mornings, I notice exhaust fumes collect on the rear window, then immediately evaporate away.
View 3 RepliesI collected a 6 month old demonstrator Phaeton on Friday to replace my previous 3 year old.
It's interesting all the little changes in the upgrade model, and it has (to me) a different feel. Quite a bit of this may be due to the 19" wheels which do contribute quite a but more road noise at higher (motorway) speeds.
My real query is the sunroof on this car. I hear significant wind noise from the closed roof at higher speeds (an indicated 80 to 90 mph). On inspection I suspect that the front lip of the sunroof is a few mm proud of the roof.
04 GX470 , open the back window while driving also had front windows open and all of a sudden I hear this noise like a helicopter to find that my moon roof was vibrating ? So I closed the back windows and everything was normal?
View 12 RepliesWhen I fuel up I hear a loud thump in the back of my vehicle, I then hear the gas pump nozzle click off after about another half gallon is pumped in. Without understanding the design of a tank or the gauge float etc. I am guessing that something is getting stuck and releasing under pressure once the tank fills up. Of course this has me more than somewhat concerned from a safety perspective. Note that this vehicle was brought in under warranty for the fuel sensor issue and the part was replaced, would this be related to that? Will the repair still be cover as a part of that work even though my vehicle is now out of warranty?
View 5 Replies2007 Camry LE 4cyl 125XXX miles ... The car sounds horrible at idle, but its not rough/shaky, just loud with a constant "thump, thump, thump" sound. It also whines with RPM increases, not just acceleration, but also while in park or neutral. Took it to Auto Zone and it tested with a bad voltage regulator in the alternator. In the process of calling around to different shops, they all seem puzzled that the alternator is bad, even though I replaced the battery 10 days ago and the battery light still flashes off/on while driving. So, before I go sinking a few hundred bucks into a new alternator, should I be looking at something else?
View 5 RepliesI just picked up a used 2009 LS 460 AWD last week with 45K miles. I have put about 1000 miles on it so far myself.
When I hit any small depression in the road at 10-45 mph I hear a thump in the rear. The bigger the depression and the more weight in the backseat, the louder the thump noise and even an occasional bottoming out feeling occurs. It hasn't happened at highway speeds so far.
The bottoming out feel occurs only with a medium to large depression. I am not talking about a pot hole, just pavement depressions where two sections are not of equal height or you are transitioning from a primary road to a side street and the is a depression to allow for water run off, etc.
If I have someone sitting in the passenger seat and the backseat and accelerate quickly from a dead stop, I get a similar rear thump and even a bottoming out feel. This occasionally occurs even without a without a depression in the road. With no one in the back seat it does not do it unless there is a big depression in the road.
Finally, when cornering on a 270 degree off ramp at 40 to 50 MPH the rear end will start to hop and bounce. If I slow down to 15-20 mph it goes away. Still, it is irritating and embarrassing. I have tried all comfort settings and get the same results.
Not sure if normal or a malfunction. Twice over the winter here in MN I have been accelerating and when I hit a icy patch the car made a loud thump/clunk noise loud enough to make be think something broke or that I ran over something like an ice block.
I had it looked at by the dealer and everything is suppose to be working normal. I tried to replicate ite on some ice but the traction control kicks in like normal with the flashing and all. I don't normally accelerate hard so it's rare I get traction control to activate.
Car is TDI SE
The other day, I was coming home from work. After dropping off co worker, an old man pulled out infront of me. I applied the brakes. As car came to stop I heard a loud thump come from rear. Sounded like i was either bumped by a car, or maybe my entire rear end slid up 5 inches. But that's kinda what it was like. Then after the thump, I put my foot on gas pedal, and instead of car moving forward, the engine just revved. No movement, revved to like 3 grand. I let foot off gas pedal. And tried again. Car moved as normal. Then on the way home i attempted the same combo of rather quick brake and then gas. Same kinda thing happened. Not so hard of a thump. But noise from rear followed by the car no moving, just revving up till i stop and then try again. So even tho my story may suck n my explanation my suck more, whats going on? I just picked this wagon up. 01 glx 65k.
View 3 RepliesVery loud very violent thump while driving at all speeds. Becomes more often and not as loud while accelerating. Decelerating becomes loud and violent again. Tranny fluid is fine and doesn't smell burnt. I haven't owned the vehicle very long but my family enjoys it.
View 7 RepliesToday my car made a pretty loud thump when I put it in reverse and slowly let go of the brake. I haven't driven the car in 2 weeks. Afterwards, every time I brake there is a soft thumping sound that I can feel through the steering wheel, and the sound slows down with the speed of the car. I think I can also hear a very slight grinding noise while driving slowly in a quiet area.
I read in this forum to use the parking brake in an empty lot to see if its coming from the back tires. My question is, what was that loud thump in the beginning? Also, is it safe to drive to the mechanic (or can I fix it myself..)?
On the way to work this morning in stop-and-go traffic, I noticed a new, weird noise from my week-old 2012 GTI with less than 500 miles on it.
The noise happens when letting of the gas in gear. Doesn't matter what gear you're in or what the engine speed is. Around a second after getting of the gas, there is a loud, depp bass thump, almost like a subwoofer hit from a close-by car. That's what I originally thought it was, but later determined it's something from my car.
What it could be? An exhaust noise? Something hitting? Is this a common noise on the new GTIs?
On my way home from work tonight cruising on the highway, heard a loud thump followed by continuous thumps thereafter. Knowing this wasn't good pulled over to find a nice big nail in my passenger side front tire, great. thought I could make it home, I was about 6 exits away...one exit later nail flew out and tire was loosing air.
- luckily for me, I had a friend who lived nearby the exit the nail flew off and put on the spare.... now my question is I noticed some camber wear on the tire.. 15,200 miles to be exact on the stock oem bridgestones.
- I know these tires are complete crap but... is this camber wear normal? I've seen other posts about it but, is it the tires? or something to do with the car? I am pretty sure my alignment is fine. If I buy a new set of tires eventually will this end up happening again? Trying to gain some knowledge for the future.
Also is it true that with AWD cars, if you change one tire you have to change all 4? because it might mess up the drivetrain or something, at least that's what I was told.
What can I do about my car it's not shifting, it's stuck in high gear and when I go from park to reverse it makes a loud thump. The check engine light came on and the codes are transmission control module it's a 2006 and only has 30,000 miles on it. It's hard to believe it's the brain so we changed the fluid and cleaned the sylinoids but then when I drove it around the block I put it in reverse it didn't make the loud noise and it shifted fine for a minute before I got around the block and almost home it made a loud banging noise and went back to not shifting again. What the problem could be.
View 5 RepliesOur excursion usually sits unless we are towing or need to haul a group of people. The past three days my wife has been using it as a commuter. Yesterday she told me that two times at start-up she has heard a loud clunk/thump sound coming from the rear of the vehicle. At first she thought it was happening when she engaged the brake to put it in drive. Today she called me and told me the sound came just after start-up while the vehicle was warming up before the brake was applied. What this could be? I wish I would have observed it so I could give more details.
View 2 RepliesV6 Touareg, Sunroof, roof racks (locked together at rear.) At certain speeds (40-45mph) there is a loud vibration on the roof. If the sunroof is opened or raised, the vibration stops. Nothing visible on the roof or sunroof which would suggest the cause of the noise.
View 4 RepliesPurchased a new 2.0T Santa Fe this weekend. While driving it home from the dealership noticed a loud wind noise between 60-80mph. We took it back to the dealership within 30 minutes and talked to the service manager. They put us in a loaner Genisis and said they would take the front end apart and see where the noise was coming from. The dealership called back this morning and said they can't figuer out what/where the noise is coming from but they do agree it is a wind noise.. They are offering to swap the vehicle out with another one next week when it is delivered. High pitched noise while driving on the freeway?
