Two years at the same age, so the older one is not punished for having been on the road longer.

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 1990 look busier because it has been on the road longer. This page counts reports in the first 432 months for each year, so both years are the same age.
In that window, the 1991 has 40.9% more owner reports than the 1990.
The mix also shifted: Engine is a smaller share of reports on the 1991 (11.1 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 Engine. Do not pick a year from the percentage alone.

Frequently asked questions
Which Volkswagen Jetta year had more problems, 1990 or 1991?
In that window, the 1991 has 40.9% more owner reports than the 1990. 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 432 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.
