Beginning January 2007, our 2001 V70 would "shift hard" when shifting from "p" to "d" or from "r" to "d" or when accelerating from a low speed. We thought it was the weather causing the issue due to it being intermittent. It became worse and shift became harder. Appt in April concluded it "may be" the tcm. Software was upgraded and we were told there would be an "adjustment" period. All under warranty. Took a week to fix what was noted as only needing 30 minutes to fix. End of June, called to state same thing is happening that the issue wasn't fixed. Volvo checked warranty and contract ended just three weeks prior. July 10, took V70 in for "diagnostic" and we need a "new transmission". Volvo will not take responsibility nor see the problem as pre-existing. Nor will they see the issue as unresolved from the initial visit. No diagnostic apparently done the first time. Coincidentally dealer reported there were more issues with the car such as suspension which was fixed just recently. We had put no more than a few hundred miles on the car since the last visit and all of these issues are just appearing, coincidentally after warranty expired. There were no issues less than 60 days ago, at least none reported to us. This incident has happened to other consumers at the same dealership. Volvo is not cooperative and we had caught the mechanics in deceitful statements by "reminding" them that was already dealt with. . . Funny how it was no longer something that needed to be fixed. The "new transmission" is still needed apparently after a total of only 80k miles on the car. It was at about 42k when we bought it in Dec of 2003.

Etm/ecm replaced 1/2006. Subsequent software upgrade 05/08/2006, 08/09/2006. Rough cranking idle. Subsequent shifting problem with transmission. Follow up with software upgrade tcm on Aug. 9, 2006. Problem still present. Transmission shifting jerks between 2 and 3rd gear upon acceleration/deceleration. Rough shifting with kick down shifting at speeds +60 mph.
: the contact stated while driving, at various speeds, the electronic throttle control module light illuminated followed by the vehicle operating at a reduced speed. The vehicle was seen by an authorized dealership for inspection and replaced the computer, but the problem returned. The vehicle was taken back to the dealer. The service department replaced the battery. Afterwards, the problem persisted and the vehicle was again seen by the dealer. The dealer determined the vehicle needed a new computer and the vehicle is currently at the dealer awaiting this replacement. The consumer stated he is still experiencing stalling problems. The manufacturer will not authorize the replacement of the ets. The dealer stated no codes were showing up. Updated 08/25/06.

Volvo V70 2001 station wagon. Car accelerating and traveling in the 40 to 50 mph range vibrating as if problem maintaining pressure to hold the speed. Took to 2 different dealers - 1 replaced cars main computer (was under warranty)- problem was not corrected, then problem was diagnosed as a secondary computer, replaced at a cost of almost $1500. Problem appears to be reduced but still happens. Vibration in the 40 to 50 mph range --like the car is lugging in too low of a gear or not getting enough gas-- have been afraid to take car on highway trips because it was after/during these trips problem was most pronounced.
Mileage approx 115,000 when purchased now 120,000 within 8 months. Hardly hard use. Failure of ecm and O2 sensors, on two occasions the second within 1000 miles and 1 month of first repair. Caused the car to surge, if restarted might stall and generally become dangerous to drive. No warning of failure. Volvo dealerships well aware of problem and offered immediate and correct diagnosis prior to checking the computer codes, without needing much investigation. 2 dealers worked on the car one don bayer in washington and independence Volvo in charlotte. Instructed independence Volvo dealer to make car safe and roadworthy. Uploaded faults and downloaded onto vehicle, new software. Within 1 month new symptoms appear. At various times these lights show and reset abs warning, engine warning, traction control warning, speedo failure, check engine, service warning (even though service is just carried out). Symptoms include lack of throttle response when pulling away, when speedo fails. No warning of change in status means this happens during turning maneuvers with potentially dangerous or lethal consequences. Checking various sources note that abs module failure is common making the car potentially unsafe in emergency, not only for braking but during acceleration as the cars ability to pull at its normal rate is vastly reduced, adding throttle does nothing, but if the system turns back on again no warning, the speedometer just comes back to life ) this can cause unneeded fierce acceleration. I noted one death on the highway of a young woman who appeared to accelerate off the road during a benign maneuver and am concerned that this on/off speedometer/abs transmission problem might have been the cause rather than the ecm currently the focus of the investigation.
While on a vacation in montana our 2000 Volvo xc70 had rought idle, stalling, no response to accelerator (would not go above 20 mph) and eventually would not start. There were no Volvo dealers in montana for repair and a local mechanic instructed us to pull the main fuse to re-set the computer. This would get us going again but it would happen again every 50 or so miles. Dealership back at home replace the electronic throttle module at a cost of $1200. There appears to be a high number of etm failures in these cars and it is a known problem with Volvo.
Abs anf tracking system off warning lights come on. Sometimes at startup, while driving or braking. Dealer has serviced system with new sensors and resetting computer with no success on numerous occasions. They say it isn't important.

Consumer believes there may be a malfunction in the traction control which caused the vehicle to skid, with less than 1/2 inch of snow on the ground, and crash into a pole . Nlm.
While driving abs/ tracking light illuminate on dashboard. Please provide any further information.
