1 Alternator/generator/regulator problem of the 2006 Volvo S40

Failure Date: 10/09/2013

At least 5 times I have had the car in the Volvo dealership. The car without warning, powers down to 50%, the windshield wipers start up, all the gauges drop to zero position and abs brake malfunction lights light up. If you pull over and stop, the car shuts down and you can not pull out the key. If I wait 15 minutes, the key can be turned off and you can restart the car. While the check engine light stays on, everything else is normal till the next time. It had done this 6 times in the last 6 months. Dealer can not figure it out other them a electrical malfunction from somewhere in the computer. If it happens going up a grade or hill, the power down slows the car in which is is sometimes impossible to power up over the hill. Every time we take it to the dealer, it then runs with no problem, but lasts 2 or 3 weeks before acting up again. They have changed the batter, alternator, unplugged and replugged the computer terminal. This car is unsafe and unreliable to take on long trips. Do you know of a recall to get this problem fixed ?.

2 Alternator/generator/regulator problem of the 2005 Volvo S40

Failure Date: 01/30/2010

I have been waiting for over 1 month for a new alternator for my 2005 S40 Volvo. I cannot get an answer from anyone in Volvo why it is taking so long. Of course, I can not drive the car I have been told by Volvo that 139 other Volvo owners are in the same condition. Please help.

3 Alternator/generator/regulator problem of the 2000 Volvo S40

Failure Date: 09/21/2005

Bought a new 2000 Volvo S40 in April of 2000. The car now has 60,000 miles on it. . . . Light driving by most standards. At 18,000 miles rear brakes and rotors were replaced at a cost of more than $400. Front and rear brakes have been replaced another time since then. On 9/21/05, I have now also had to replace the alternator at a cost of $600. This car only has 60,000 miles on it. I have read a lot of other discussions online from other 2000 Volvo S40 owners who also complain about the car running through brakes every 15-20,000 miles.

4 Alternator/generator/regulator problem of the 2002 Volvo S40

Failure Date: 01/20/2005

I have had to replace a headlight 3 times and a taillight 2 times, a console light, and the fuse to my cigarette lighter in my 2002 Volvo S40; 5 of these things in the last six weeks. The Volvo dealership says Volvos now ( they didn't specify any particular year of Volvos) are blowing headlights so frequently, that the customer reps keep headlight bulbs in their desk drawers and replace them for free. To me, this means either there is a significant problem with the Volvo voltage regulators or this particular Volvo dealership is putting me off to try keep this repair from being taken care of by my car warranty. I say this because the first time I asked about my lights blowing so frequently, they told me it was because light bulbs tend to blow in cold weather. The second time I asked, they said all Volvos were doing that. I looked on your site about safety recalls on Volvos and saw nothing about voltage problems. Tonight I have also sent an email to Volvo. Com site so obviously I haven't gotten a response from them. Since safety lights (headlight and taillights) are an issue with the problem I'm having with my car and the Volvo dealership says it's a common Volvo problem, I thought I should pass this by your site to see what you have heard.
