Was working fine and now does not crank over no sound at all battery is new
Got codes P0014 - P0015
Repair man said that all valves were warped but could be fixed and no piston damage, after having it for a month now they said that the entire engine may need swapped. What does this sound like to you and what kind of money are we looking at?

cools for a little while then shuts off or blows hot can cut off a few minutes and then turn back on and its ccol again.
I can see where coolant is leaking from two hoses and took it in to be serviced. The est. came back at just over $900 to repair the Gasket-Thermostat, hoses, and coolant system service w/ extended life. Is this all necessary. I guess what I'm asking, does the gasket/thermostat need to be replaced if the collant is leaking from the hoses?
I was at a redlight and about to make a turn and the car just shut off. I did not see any warning lights on just the oil light/ car did come back on/ what should I do? It had never done that before
Hey everyone I've recently been having some issues with my headlights. I have a 2005 Volvo S40 2.4i that came stock with Xenon lights. Question number one.... I've had to replace my headlights 2 times in the past 3 years, am I buying the wrong bulbs? I dont know if theres a difference between Bi xenon and HID lights and when the stock ones went out I switched them with D2S bulbs from (Meng motorsports). Anyway the first time they went out I put in D2S bulbs and they worked great, no conversion kit needed. I just swapped bulbs and it was golden. 2 years went by and the bulb exploded again so I changed them with the same bulbs as the first time. They worked fine for about a year and just recently I've be driving and my lights or just one light will flicker and shut off. All I would have to do to fix it is turn the lights to the off position and then back on and they worked fine for about 10 to 20 more minutes. Even more recently however its been getting worse. The trick of shutting them off and back on only works for a minute or two before it fails again. I've tried to disassemble the light and shake wires looking for a looking for a loose connection but to no prevail. One thing I noticed is a weird humming sound that is interrupted when that fail. If anyone has any knowledge on what the cause is I would really appreciate it. Whether its the ignitors, the ballasts or the bulbs Id love some help!


A few days ago, I came out of a mall and the flashers were going off. I unlocked the car, thought that I mistakenly hit the panic button and proceeded to start it. Then, the flashers started again. The horn started honking and the screen said "crash mode". After that, I turned it off and on again and it flipped from crash mode to "valet mode". Turned it off and on again and proceeded to try to drive home. About a mile in, it stopped on me, went to crash mode and I called triple a.

While parked outside my house, the alarm and flashers started going off again due to no apparent reason. I have since disconnected the battery.

Does anyone know what could be causing this?

I may have pulled the seatbelt too tight when moving passenger seat forward to make room for an infant car seat to be placed in rear seat base; the passenger seat belt retracts okay now and works well but light still on
Been on and off for a few months. Ill be driving and all of a sudden I get a brake failure stop safely light and all my gauges go dead. Sometimes from there the MPH will come back on and only the ABS service light stays. Turn the car off turn it back on and it says check engine, engine system service urgent turn it off take out the key and turn it back on and the urgent light is gone only the check engine light stays on until I turn if off and on again. Sometimes ill also get a power steering light as well. Also if I dont wait till the MPH comes back on and I turn off the car while the gages are dead ill get an immobilizer message for ten minutes then it starts up fine. Radio still works windows still work but sometimes driving is rough while its happening. So it definitely a High Speed Communication error. Already tested the alternator and changed the bad battery. I bought a new ecm but havent spent the money to take it to the dealer to get it re programmed cause I want to make sure that its the problem before doing so. Does anyone have any ideas on the issue? Its so frustrating and makes driving anywhere painful.
