The contact owns a 2000 Volvo V40. The contact shifted into reverse with the brake pedal engaged when the vehicle unintentionally accelerated and drove over a plastic trash receptacle, ceramic pot and then crashed into the side of a nearby house. There was no personal injury and the exterior side of the house sustained minor damage. A police report was not filed. The rear bumper completely detached and the vehicle was in the process of being towed to a collision center. The manufacturer was not made aware of the failure. The failure mileage was unavailable.

2000 Volvo V40 - very well maintained, 2nd owner, approximately 83,000 miles. I started noticing that the car would surge on the highway with the A/C on and when I had steady pressure on the accelerator (I.e. icruising at a steady speed). The surge in RPM's would be rhythmic, very subtle (100-200 rpms) and continue indefinitely until I turn the A/C off - at which time they would cease. They would sometimes resume when I turned the A/C compressor back on. This happened infrequently over the past month (it's June in ct, my state of residence) and would not happen every time I ran the A/C - but only occurred when the A/C compressor was running. Then a remarkable thing happened today - while cruising on the highway and with the A/C compressor on - the care suddenly and violently surged in a way that it had never done previously. The increase in RPM's was significant enough to cause the automatic transmission to downshift into the next lowest gear. Fortunately, I had enough space between my car and the car in front of me to allow me time to respond without having and accident. I immediately put the car in neutral and the RPM's started spiking to almost 4,000 then quickly back down to 1,000. The RPM's continued to this rapid back and forth spiking and dipping for almost 30 seconds. I turned off the A/C/ but that didn't have an immediate affect (as was the case in the previously mentioned episodes when the spikes and dips were much more subtle). When turning off the A/C didn't do the trick ((as it had in the past) I then immediately checked the cruise control - it was off. I then stabbed at the accelerator with my foot several times before it finally settled down. And I have the factory Volvo rubber mats that are secured to the floor by a positioning pin (I'm meticulous about my car the mat was no where near the accelerator). I am naturally very wary of this car now, especially after reading the many complaints about unintended acceleration for this model. Why no recall?

Vehicle idle increase on braking to about 1500 rpms. When put in park, idle increased to 4500 rpms. I tried taping the gas to see if rpms would go down. Instead rpms increased even higher to over 5500 rpms. Turned the car off. Tried to restart car and rpms immediately went high again. Turned the car off a second time. Could not restart the car. A similar incident happened 36 hours later after the car had been at the repair ship. That incident happened after driving around a parking lot looking for a space. RPM's increased. When put in park the RPM's increased to over 4000 rpms. Car towed to repair shop.

The vehicle both accelerated and decelerated without input, placing me in a very unsafe situation. When I stopped the car the engine, which had overheated, the radiator hose blew out. The radiator hose was replaced. I am currently discussing correction to the electronic throttle module which appeared to be a problem with this make and model.
