Our reliability stats suggest how reliable the
BMW X5 has been in the past year. But which way has it been trending?
And how does one model year compare to others when they were the same age?
To provide some insight into these questions, the graph below
draws from up to two dozen quarterly surveys.
Each dot represents a quarterly update stretching (where we have
enough data) from when the cars were new through age five.
If you see a bump, this often represents a single problem that was common for a few quarters. You might be able
to identify it from the problem descriptions. If you do, you can share this information
in the comments.
