4 Vehicle Speed Control problem

Failure Date: 09/02/2005

Volvo C70 presented a problem with the engine revving and down by itself, and mostly noticeable while standing still at idle. I took the car to the dealer, and they informed me that they had to replace the electronic throttle module (etm and throttle) body along with some other parts. I paid and had the repairs completed. The dealer informed me that they put a new etm in, but that the etm light indicator on the dashboard came on, which was not the case when I brought the car in. They put a second one in and the light came off. I took possession of the car and drove to work. After work I drove home, and the etm light came on again. I thought the light was not a problem since I was told so by the dealer. A few months later while navigating the web I found a forum mentioning that Volvo has a problem with the etms. Several sites claim Volvo is trying to hide the problem and not taking sufficient actions to inform customers. Since light is still on now, I will take my car back to the dealer and fight with them, but wanted to inform NHTSA of my experience so far.

Dt:the problem began last year while driving in the neighborhood at about 25-30 mph, the owner felt tugging and hesitation. There were no lights on to warn owner of a problem. The car experienced a loss of power until the operating temperature went up to normal temperature problem happened every time the car was driven, and got worse with time. The problem happened about 20 times, then owner took the car to the dealership. The dealer notified owner he would need to replace the electronic throttle module ( etm). The fault codes that showed electronic control module (ecm 9150 and 914f). The owner did not have the repairs done and the problem got worse. Then about 9 months later, the owner experienced the significant loss of power while driving/coming on to the off ramp, and merging into traffic. The owner tried to speed up. There was a feeling of complete loss of power at 3000 rpms. The owner pushed the accelerator to the floor. There was no response. There was no power after 3000 rpms. There was a feeling of the car having only one gear. The owner coasted off the road and restarted the car and it was fine for a while. The problem is staying the same now, not getting worse. The owner wished to have it repaired, but could not afford it. The owner has spoken with Volvo, who won't offer any assistance. They say the car was out of warranty.
