I added my V50 to help...

Are you combining the S40 and V50's? It would make a larger sample size pool, and there is no mechanical difference AFIK.

 

Thanks for joining. We are combining them.

So, how have these cars been doing lately?

Our reliability stats for the S40 now include owner experiences through March 31, 2015. (Others are nearly a year behind.)

In terms of repair trips per 100 cars per year ("low" is best):

2007 S40: 59, moderate, small sample size
2006 S40: 99, high, small sample size
2005 S40: 69, low, small sample size

No stat for a model year? Then we very much need more participants for it. Same for those with small sample size notes. Next updates in August and November.

Our reliability stats for the S40 now cover the year ending June 30, 2015. (Others are over a year behind, and so report how these cars were doing when a year younger.)

Repair trips per 100 cars:

2007 S40: 65, moderate, very small sample size
2006 S40: 91, moderate, very small sample size
