A model with a bad reliability reputation is usually treated as uniformly bad. Splitting complaints by model year shows how often that's wrong.
| Model | Worst year | Share of model's complaints |
|---|---|---|
| RAM 2500 | 2018 — 2,489 | 54% |
| Dodge Ram Van | 2,268 of 4,600 | 49% |
| Nissan Titan | 34% | |
| Pontiac G6 | 32% | |
| Dodge Journey | 29% | |
| Chrysler 300 | 28% |
2017 versus 2018: nearly four times apart
The RAM 2500 accumulated 4,592 complaints across fourteen model years. The 2018 alone accounts for 2,489 of them, with brakes as the leading component. The 2017 — the same truck, one year earlier — produced 670.
Anyone shopping by model reputation treats those two trucks as the same purchase. The complaint record says they aren't remotely.
Why single years go wrong
A supplier changes. A new brake component, a different sensor, a revised pump — introduced for one season and quietly reverted after the reports pile up.
A generation launches. First-year builds of a redesign carry the teething problems. By year two the fixes are in production.
A running change mid-cycle. Manufacturers alter parts without announcing model years, so one production window differs from the ones on either side.
This is why averages mislead in both directions
Complaints are extraordinarily concentrated generally: 76.1% of all model-years in the database have zero complaints, and the top 1% of those that do hold 15.1% of the entire volume. The top 10% hold 61%.
So a model's average is usually dragged by a small number of bad years, and a model with a clean reputation may simply not have hit its bad year yet.
How to shop with this
Search by model AND year, never model alone. The gap between adjacent years of the same truck can be four times.
Look at what the complaints are about. The 2018 RAM 2500's leading component was brakes — that's a specific, checkable thing, not a vague reliability concern.
A cheap example of a notorious year is cheap for a reason. The market prices these in, so a bargain on a known-bad year is usually the market being right rather than an opportunity.
Check the individual truck. Complaints describe the population; recalls and title history describe the vehicle. A VIN check shows what's open on that one. We looked at how complaint volume builds with age in a car's complaint count multiplies by six, and which model years drew the most overall in the worst era for complaints.
Frequently asked questions
Can one model year be much worse than the others?
Dramatically. The 2018 RAM 2500 generated 2,489 complaints — 54% of the model's total across fourteen years — while the 2017 produced 670. The Dodge Ram Van shows the same pattern at 49%.
Why does a single model year go wrong?
Usually a supplier change, a first-year build of a redesign carrying teething problems, or a running change made mid-cycle without announcement. Any of these can affect one production window and not the ones either side.
How concentrated are car complaints overall?
Extremely. 76.1% of all model-years in the database have zero complaints, and among those that do, the top 1% hold 15.1% of the entire volume while the top 10% hold 61%.
How should I use complaint data when shopping?
Search by model and year together, never model alone, and read which component the complaints name — brakes on the 2018 RAM 2500 is a specific checkable thing rather than a vague reliability worry.

In 2014 the Number of Recalls Jumped 55% in One Year and Never Came Back Down
You'd expect a bad year for recalls to be followed by a return to normal. Counting campaigns by year shows 2014 wasn't a spike at all — it was a step change that stuck.
Tyres Were the 7th Biggest Source of Car Complaints. Then They Went to Zero.
Whole categories of car defect don't usually vanish. This one did, in about five years, and the reason is a single scandal that reshaped how tyres are monitored.
Cars Built Between 2000 and 2006 Generated More Complaints Than Any Era Before or Since
Reliability is supposed to improve steadily. Plotting owner complaints per model against the year the car was built produces a hump in the middle that doesn't belong there.
