I replaced radiator myself and did not measure how much fluid I lost when trans. hoses were disconnected.

Been noticing a rattling noise the car is idling in park it's fine
Shift into reverse it rattles for a second
Neutral is fine
Drive it rattles 3 times
And when accelerating past 20 or 30 it rattles for a second as well feels like it's on the left.

Joints maybe or mounts my drive in Houston always has a ton of bumps and it rattles when I go over those as well.

01 s40
173k
Had battery tested and fully charged at autozone
Then figured it was that alternator
Had that and the serp belt replaced.
Ran fine for a week then I had the door open for maybe 10 mins (car off light on) and then it wouldn't start.
Jumped it and took a drive for 30 mins to see if it would charge up, and wouldn't start again.

Thinking there's a power drain from a light or something any clues on common issues or where to start looking?

Mechanic said there was corrosion but didn't tell specifics. What should I look out for and what areas would make it not worth purchasing the vehicle.

I went to the dealer to have all of the faulty codes reset. They told me that I could just drive it for 50 miles as the drive cycle. The car passed everything except the OBDII based on drive cycle. The dealer will probably charge me again if I go in regarding the failed smog. I need to know if there are any shops that do the DRIVE CYCLE.

Car dumped all the fluid and will not reverse

After driving a small trip ( round trip 3 miles ) after the light turned green I went press the gas pedal and got no accrleration and crept back home at 2 to 4 miles an hour. Please Inform me of any known issues that would cause this problem

same all the time sits for awhile then 15 great minutes of cold air then hot all the time ..this goes on

Started after having the tires rotated

I just got the car today and I am having some issues with the sunroof. Basically the buttons do not correspond at all with the correct actions. I have yet to successfully do anything but tilt and un tilt. I have never actually seen the sunroof retract. Even with the titling it was pretty random which buttons worked and were almost always wrong. I checked and replaced the two corresponding fuses just to be safe with no fix. I also tried turning the key a bunch of times in the drivers side which apparently resets stuff but that did not work either.

The computer is having trouble recognising sensors and as a result the engine light will not turn off all the time and when it does turn off, the computer still does not recognise this(the sensors).
The ABS module/brake light will not go off. The odometer will not work either, which affects engine idle. I have been all over the place in our area trying to get help with this problem so my car can pass the annual smog inspection,I have spent a lot of $ but have gotten no solution to the problem. Time is running out. If anyone reading this has any answers, please let me know. Thank you

Just purchased a 2007 S40 2.0L diesel. I recently noticed that it's leaking oil. As I took the engine tray down to do an oil change since it's last one last April. I power washed the oil that was welded to the subframe before I left work to come home but when I got back I noticed it's leaking oil from the back of the engine, the flywheel seems to be wet from the oil. What would it be? The oil return pipe from the turbo? The oil filter housing O-ring is perished? Crankshaft seal is gone? The front of the engine doesn't have any oil in it not on the auxiliary belts. You can see up from underneath it at the back of the engine it's wet from oil.

When I am driving my car when I hit 40+ mph, my car sound like I'm going through a tunnel and it's egg is and shakes a little. My dad thinks it might be my wheel bearings.

can you call me please 336 287 0711 Rochelle

We're reading code P0237 on our Volvo. We replace the boost sensor and reset the check engine light. Light hasn't come back but the code is still popping up. Can't pass the emissions check with the code. Any ideas on what to check next?

the speedometer and the fuel gauge no longer work. the indicator light of the fuel gauge is on no matter the quantity of fuel in the tank

We have had the vent blown out with air by general mechanic. That solved it for 1 fill up. Volvo dealer says they cleaned out gas tank fill vent filter and checked lines and all clear. That helped for 1 fill. Dealer mentioned replacing a pump?

Even with headlamp switch off, everything is on

Middle of driving and the emergency lights come on. It will stop for a few mins and do it again. The batter in the car is brand new.

and right now my right tire is hanging onto two good studs I can't move my car at all I was driving and I heard rattling or knocking in that same tire and the two studs broke

At what mileage do I need to replace the front shocks?

Having noise in the right front end. Had the CV joint replaced. Still there and getting worse. Checked motor mount. Is ok. Please suggest what other things this could be. I am very limited financially and cannot afford another shop looking and fixing something not broken. This car has 60k miles on it and has not been driven roughly at all. It is adult driven. No teenagers have abused it.
Though the roads here in Louisiana are horrible.
Please any suggestions are helpful.
Thank you

Had the belt, fuel pump, rebuilt engine replaced. There was fluid at the bottom of the right front wheel well. The mechanic says the leaked onto the timing belt and it needs to be replaced. I was told that can't be the case because the belt is encased.
