NHTSA Consumer Complaints complaints · snapshot 2026-09-07
Share shifts show how a vehicle's problem mix changed. They do not measure reliability, and complaint counts are not normalized for sales volume.
In plain English
A lifetime total makes the 2005 look busier because it has been on the road longer. This page counts reports in the first 252 months for each year, so both years are the same age.
In that window, the 2006 has 29.0% more owner reports than the 2005.
The mix also shifted: Transmission / driveline is a larger share of reports on the 2006 (10.6 points). That is a change in what owners named, not a score.
Open both year-pages. Check the VIN at nhtsa.gov. Have a shop inspect Transmission / driveline. Do not pick a year from the percentage alone.

Frequently asked questions
Which Porsche Cayenne year had more problems, 2005 or 2006?
In that window, the 2006 has 29.0% more owner reports than the 2005. Lifetime totals are not used here because the older year has had more time on the road.
Why not just compare lifetime complaint totals?
The older year has had more time to collect reports. This page holds age constant by counting the first 252 months for each year.
Does a larger share of one system mean that year is worse?
No. It means owners named that system more often in the file. Inspect it. YearTell does not publish scores or a list of years to skip.
