I started having a problem with my 09 Impreza automatic when it was just under 60K miles (aka under warranty), nearly 3 years ago. While driving it would slam and feel like it had been shifted into Park for a split second, sometimes one big slam, sometimes several shudders. Some but not all the time 3 lights would come on- AT oil temp and 2 icons to do with AWD (can't be exact, don't have the car now). Repeated trips to the dealer never yielded a read of ANY codes. Things seemed to get better when I had a routine change of transmission fluid.
Fast-forward to August of this year, the problem happened yet again. This time they got a code read and replaced the valve body, a $1300 job OF COURSE not covered by the warranty, even though the problem is well-documented as ongoing from when it was covered.
When I picked up the car I was told this is a "highly unusual" problem caused by metal fragments in the fluid, but there might be further repairs needed which would only be known after I'd driven it more.
Three weeks later, same problem. NOW they say it's a short in the transmission harness wiring and the transmission is not faulty at all, while still stating that the valve body did need replacing last time. So, TWO separate problems both causing the exact same symptom? Really? And today I was told that the metal in the fluid is normal. So why did the valve body need replacing, then?
Meanwhile my August case with national Customer Service has somehow been closed for the valve body issue and they take no responsibility. As of yesterday, however, I had been told it was still being investigated. They are willing to cover the harness replacement but given the conflicting info I now don't trust anything I'm told. HELP!
