Had taken my S80 to the Volvo dealership a number of times complaining of engine hesitation and stalling. Volvo"S diagnostic computer system "vadis" output codes clearly showed default codes indicating a faulty module. The service manager at this steadfastly refused to replace the module "due to cost". I warned him of the potential consequences of trying to operate this vehicle with unreliable engine firing and the associated "stalling" that occurs without warning. I expressed my concerns to him about the danger that this problem presented for me and other vehicles which I had experienced during previous "stallings". unfortunately, after tremendous research and a number of phone calls before I could bring this info to bear to force the dealership to honor their warranty I experienced a "stalling" event while driving on the expressway which lead to a single car accident, resulting in a total loss of my car.

Re:1999, S-80, T-6 Volvo. Saw an ap article in my local paper today re complaint investigation. I experienced virtually all of the same problems cited in the article. Namely stall w/O warning, from a stop, step on gas and barely would move(like slipping clutch on a manual transmission), had numerous incidents where I felt vulnerable and unsafe in traffic, loss of power steering etc. Sounds very much like these other complaints. At same time I had lots of incorrect "readouts" on dash panel. I complained to dealer who said this all could be related to the ABS control module which was replaced at cost of $825. Old part was not given back to me. Of note is that during the same repair a belt was replaced which they did give back to me, but not the module. Mileage was only 61,376. This module did solve the problem however I am now getting another goofy readout that dealer says could be a defective module. Current mileage is 61779. I did not think that failures of this type should occur at such low mileage. At the time I asked if there was a recall for this and was told no. I am not happy with this situation and II do suspicion that a defect exists.
