1 Brake Sensor problem

Failure Date: 05/02/2014

(s40 2. 4i) initial car message: "brake failure, pull over safely. " I continued to drive home since I was a few blocks away. Message changed to "anti skid service required" then back to brake failure again. Difficulty accelerating after stopping, felt like the parking brake was on but drove ok once accelerated. Attempted to turn off car but message changed to "immobilizer, check manual" and could not turn key to off position. From what I read in the manual, it appeared that the card didn't recognize it was in park. Turned parking brake on and off a few times and was able to turn off car. Brought to local mechanic who replaced brake pad sensor and anti-stop switch. --in and out of auto repair shop 4x over the past month w/the same issues and new symptoms: wipers turned on automatically and don't shut off and new message: engine system service urgent. --mechanic replaced some rusted wires, brought to a Volvo dealer who reset computer and did not find any problems. --still having same issues. Cannot put car into drive or turn off car when brake failure or anti-skid message appear but if I wait a few minutes, I can turn the car off and on a couple of times to get to the engine system service urgent message and I can then put it into drive. Sometimes all messages go away and it is fine for a few days but then the car jerks forward as if someone bumped the car and all messages appear again. New message: power steering message flashed briefly . . Although there was no problem w/the steering. Bringing to another Volvo dealer. . The saga continues. --I read prior consumer complaints on this site and I also had the sunroof leakage problem in 2013. Entire floor of car was soaked, especially passenger side. Took 3 visits, weeks and $900 to get it fixed. Volvo first cleaned out the clogged line but carpets were wet again so they then replaced the entire line.

2 Brake Sensor problem

Failure Date: 12/06/2012

Car stalls with out warning when travel at speeds of 0-65 mph very dangerous!! there are recalls fuel pressure sensors for nearly all Volvo makes except the S40 2005 this part is truly a defective item and needs to be recalled before a death occurs on the highway!! I thought Volvo was a safe reliable car but I can honestly say this car is the biggest piece of junk I have ever spent a lot if money on. The tires blew out on the sides which also put me in danger the interior headliner fell off as well as all other material on the doors all leather is loose gear shifter cover fell apart. Gas cap broke gas builds too much pressure loosening the gas cap frequently these are just some of the issues I have. Very disappointed in this vehicle I keep my car in the garage. Only drive to and from grocery shopping and dr appts please consider recalls on the important parts of the vehicle that can save lives!.
