The car has problems starting and takes a few tries before starting up. Have also had a problem where the car was in park with the parking brake engaged and the car was revving on its own. There have also been problems while the car has been slowing down on the freeway, specifically when the brakes are being engaged the car will attempt to move forward as though it is trying to push pass the fact that the brakes are being engaged. As well as the car will accelerate faster than the gas pedal is being pushed e.g when the gas pedal is slightly pushed the car will accelerate quickly as though the gas pedal was being pushed upon firmly.

I was pulling into my parking garage and my 2000 Volvo S40 began to accelerate on its own. It revved up to 3000 rpms and I had to press hard on the brake for it to stop. I pulled over in the garage and placed the car in park. The car continued to rev. I stepped on the gas a couple of times and after about 4 minutes it returned to its normal operating RPM after which I was able to park the car.

My 2000 Volvo S40 had another unintended acceleration episode on April 12, 2010 (I filed a previous complaint #10288666 in Oct 2009). On the highway it would go 60 mph without depressing the gas pedal (and no it was not stuck and there was no floor mat in the way). The last time this occurred was six or seven months earlier. The ect sensor was replaced at that time. This last time the Volvo memphis dealership replaced the ect sensor and it has not occurred again.....yet. This was the third ect sensor replaced in about a year's time. I asked that Volvo corporate be involved to check out why this was happening. They had a field technician ride in the car with me and check it out. Basically they shared no reason for the recurrent replacement of the ect sensor and even though I continued to try to get an answer (and reimbursement for the repeat repairs). This is one of the emails I received from the Volvo investigator after their inspection and my continued dissatisfaction with not identifying a root cause ---- "[xxx], I can certainly understand your disappointment in having to replace the same part three times. As stated, if the symptoms reoccur, please either contact me directly, or contact the service manager at Volvo of memphis, randy pearson, so that we may get been involved once again to review your concerns regarding your vehicle. To date, your vehicle is performing as designed. Thank you for allowing us the opportunity to inspect your vehicle. Erica kirsch product investigation coordinator Volvo cars or North America" I am not interested in continuing to pursue this just because of repair costs I feel should be covered by Volvo. The symptoms I have repeatedly experienced are scary and a huge safety issue. I also saw an on complaint #10288666 filed on Feb 18 2010 that sounds like the same issue as mine.

Unintended acceleration on my 2000 Volvo S40. Accelerating in traffic without pressing pedal. Must press brake hard to stop. Continues to rev high. This has happened twice in the last month. After the first time, my service shop replaced the idle air control valve but it occurred again about a week and a half after that. Service technician has indicated he cannot potentially diagnose unless it is occurring when he can drive and look at it. It is a serious risk for crash or injury.

The vehicle was towed to the dealer to diagnose the failure. The vehicle and failure mileage was 73,000.

Vehicle: Volvo, S40 (year:2000), miles: 95,000 vehicle has problems in line with the other 360,000 recalled Volvo involving ETM. Why is S40 not part of recall? last weekend vehicle had recurrence of continuing problem. Vehicle suddenly and violently down shifts at road and highway speeds. This has results in rapid slowing of vehicle and a massive RPM surge. This could result in a serious accident at highway speeds. Vehicle acts like it shifts into "safe" or "limp" mode, but there are no trouble lights that come on. Have replaced mass flow censor, which did not help. When it occurs, shutting vehicle off for a couple of minutes seems to "fix" the problem for awhile. In my opinion, this is a serious safety concern and appears related to the ETM that has been the source of problems in other Volvo vehicles. Please add the S40 to the recall campaign.

The key has been sticking in my ignition when I park. This time when I could not get the key out, I restarted the car in park, of course with my foot on the brake. The car jumped into reverse and flew backwards out of my garage at a high rate of speed. It crossed the road and ended up knocking down a garage and totaling the car. The brakes were on as evidenced by the tire tread and skid marks. It was a bizarre occurrence and very frighteningly.

Three times my daughter's 2000 Volvo S40 accelerated unexpectedly. Twice (on the same night) it almost pulled her into a busy intersection. The third time it happened to the service manger (jeff) at a local Volvo dealership. After two visits from a technician from Volvo it was determined that a temperature sensor had failed. This failure led to excess air being fed to the engine which in turn led to excess fuel being fed to the engine, which in turn accelerated the engine. Volvo replaced a temperature control sensor that operates the air slide in the engine on 12/7/05.

While slowing to a stop in a parking place (1-2mph), the vehicle suddenly accelerated. Within 2 seconds, the vehicle jumped the curb, spinning the front wheels fast enough to dig 2 deep troughs in the gravel, and crashed into a brick wall 10 feet beyond the original parking space. The passenger airbag deployed shattering the windshield. The driver suffers only minor soreness thanks to the short distance between the parking space and the wall. This is certainly a defect in the S40. Two other customer reports exist concerning a runaway throttle on the Volvo S40: 879358 & 878201.

Dealer/manufacturer claimed that no known problems existed, but NHTSA had complaint ODI id 879358 since 7/1/2000. No safety defecgt listed.
