I wanted less vague, more up-to-date car reliability information. So in 2005 I started getting people together to make this possible. TrueDelta now updates actual repair frequencies, not just dots, four times a year, to report on new models sooner and track cars closely as they age.
We've been providing reliability stats for the Malibu, Cruze, and Sonic for a while now. We'd love to do the same for the Spark -- just a matter of getting enough people involved.
Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, at the end of each quarter.
To encourage participation, participants receive full access to all results, not just those for the Spark, for free. I'll share results in this thread when we have them.
