I have a 2001 Volvo V70 T5. This car has the high failure rate electronic throttle module component. During highway driving, I experienced a sudden loss of power while in passing lane of a 2 lane highway. The message window on the dash flashed "performance reduced" this occurred during while passing a semi with other cars following closely behind in a Caravan. It was in pouring rain with water from the semi splashing over the windshield. Needlesstosay, this was a nervous moment when power was suddenly lost. I was able to slow down and pull off to the next exit ramp where the engine was sputtering while idling. Shutting off the engine and restarting made the problem disappear. About 3 months later, I'm getting "performance reduced" message nearly every day. Finally trace it down to the ETM internal fault using a obdii reader I purchased to diagnose this problem. Volvo dealer confirmed the finding and replaced the ETM.

2001 Volvo V70 - traveling on major highway in this vehicle, it lost acceleration and started to reduce power, eventually resulting in complete stalling. Caught between trucks and cars going approximately 65 - 75 mph. I felt hopeless to help myself, fearing I would be killed by traffic.

The contact stated the electronic throttle module (ETM) failed. The engine idle dropped, and surged upon starting the vehicle. While driving the vehicle it surged and then lost power. The vehicle stalled while at a stop light and would not immediately start back. The vehicle started again after the fourth attempt. The ETM was replaced approximately a year ago, but now the vehicle experienced the same problems again. After the repairs the consumer continued to experience problems. Updated 01/04/06.

While driving on I-695 near baltimore experienced six episodes of sudden deceleration, and a almost stalling. Also, was almost rear ended by a dump truck on one occasion, and on another occasion by an 18-wheeler before the contact could cross slowly through lanes to the side of the road. To make matters worse, due to road construction, during two of these unplanned stops, there was no shoulder and the contact blocked a lane of traffic. The message on the dashboard read reduced engine performance. The contact turned the car off, and then a few times, noted a very rough idle and the same message. Then, turned the car off for a few minutes, and instead of the reduced engine performance warning received a needed immediate repair service or some similar message, and the check engine light was on. He drove a few miles at 60-65 mph, but the engine was running very rough. This whole episode repeated by itself 5 times during 50 miles drive. The contact made it home safely with three young children in the back seat. These problems were exactly those documented with the defective electronic throttle (ETM) in most 1999-2001 Volvo. Has an appointment with local dealer, and he will be charged the usual $1000-$1200 to replace the ETM module. Unfortunately, the replacement module was not better than the original module.

The contact stated vehicle was losing power while accelerating and would only go 15 mph. He would coast to the side of the road and turn the vehicle off and back on. This happened daily. He took the vehicle to the dealership, and the throttle box was replaced. The problem has not come back since the repairs. Updated 12/27/05.

Contact stated while driving a message appeared that read engine system service required which internally made the cruise control fail. He took the vehicle to Volvo, and also a private mechanic. The problem was the electronic throttle module.the vehicle repairs will be at the contact's expense. The consequence of not having this repair made could result in the vehicle lurching forward at any speed or it could cause the vehicle to stall out at any time. He is currently not experiencing any problems, however the vehicle is parked at this time. Updated 11/30/2005 - Volvo cover the cost of the new part and has extended the warranty on the part to 200000 miles or 10 years.

I have Volvo V70 T5 wagon with reduced performance and unexpected acceleration and reduction of acceleration. The vehicle stopped on traffic and I was almost rear ended. The vehicle accelerated while entering the garage and causing damage to the body of the vehicle. Additionally, the climate control in the car stopped working. My dealer ed schmidt Volvo in perrysburg, Ohio now saids that I need to replace my throottle module ($1300) and the processor for the climate control ($1400). The vehicle is only three thousand miles beyond warranty. I have a dangerous lemon in my hands and there is nothing I can do. I thank god that my young children where not near the garage when the car accelearted out of control. Please feel free to contact me. This car should not be on the road in its present condition.

Consumer complaint regarding Volvo electronic throttle defect. Updated 11/7/2005 - while driving the performance reduced light and ses light illuminated on the dash. The vehicle was taken to the dealer who determined that the electronic throttle needed to be replaced. Neither the dealer nor manufacturer agree to replaced the throttle free of charge because the vehicle was out of warranty. During inspection the technician found the front control arm and upper spring seat broken. The power steering fluid leaked due to a faulty hose clamp.

Initially noticed erratic acceleration, then my wife was accelerating from a stop light and the vehicle actually lost acceleration and she was hit behind by a pickup truck. The dash readout showed the message "performance reduced". our insurance paid for the $2600 in damages. Our Volvo mechanic determined that the problem was in the electronic throttle module and said that this was a fairly common occurrence in this year model.

Since the car was purchased there have been rough start and rough idle issues and acceleration issues. The issues were raised to the dealer on three occasions all with no resolution. The dealer has now identified the issue as a failure in the ETM after the service engine light came on and remained lit. Dealer quotes repair costs of $1,100.

We purchased a 2001 Volvo V70 2.4T wagon 12-16-01 from the dealer, who had used it as a loaner vehicle. This complaint is regarding the throttle control. For about a month it would feel as if a plug was bad or a fuel line clogged when driving at a steady speed. It wasn't at first noticeable during acceleration. Then a "reduced performance" message came on the dash. Finally, on 8-20-05, the car stalled on the way to the dealer in reno to get it repaired. Fortunately, we were in the right lane and managed to pull off the road out of traffic. Just a matter of timing and this problem could well have been deadly. It restarted and we made it into the dealer. The throttle body was replaced and the pvc system cleaned, as the service manager stated the problem caused it to need cleaning. The total bill was $1,336.49. I feel Volvo has a serious problem here, and judging by the number of complaints, which must be only a fraction of the number of incidents, it is only a matter of time before it causes deaths on the highway if it hasn't already.

The caller said on July 19, 2005 after driving two hours the reduced performance warning light came on. The vehicle started shaking and had no acceleration. The caller said the reduced performance light came on again on the way home. She got vehicle off the road and waited a few minutes and the vehicle started back up. Vehicle was taken to the dealer and the throttle was replaced. The caller just wanted to let NHTSA know about the failure. The caller said dealer was very nice about the repair work.
