Four problems related to transmission failure have been reported for the 2001 Volvo XC70. The most recently reported issues are listed below.
Several computer problems that arose suddenly. 1) transmission lights fail to light to indicate proper gear and car enters limp home mode (I. E. , sluggish acceleration) when starting car. No accidents. Occurs when starting cold engine and goes away after several minutes of warming the engine (inconsistent times). Dealer has installed a software upgrade, but it has not corrected the problem. The problem began without warning or other incident and happens during warm or cold weather. 2) other safety issues that arose at the same time include rear seat passengers being unable to open rear doors (stuck in child lock override mode) and driver override button is nonfunctional. Failure has not been corrected (dealer wants $900 to fix and I rarely have rear seat passengers).
Transmission failure on Volvo model year 2001. Failure not due to abnormal driving conditions. Normal driving conditions, mostly highway transmission failed at 99,000 miles. The vehicle was well maintained with all dealer suggested maintenance completed. Transmission failure, according to transmission experts due to poorly manufactured "cheap" components.
2001 Volvo Xc70 - transmission failure - when stepping on accelerator engine will increase rpm but not speed, then a surge/bump as engine seems to engage.
2001 Volvo Xc70 transmission fail at 97k miles. Transmission has never behaved appropriately, up/down shift erratic, etc. Vehicle has been the recipient of numerous software upgrades, transmission flush/filter, and a new valve body. Transmission still failed and Volvo says I'm out of luck. Bought new in 2001 for $42,000. Vehicle also failed to operate March of 2006 where a "performance reduced" message was exhibited. After turning car off for several moments, the car ran fine. I suspected a possible issue with the etm. Portland Volvo installed an etm software upgrade on April 6, 2006. Car has not had a repeat occurrence of this nature but was shifting oddly as previously described.
