GarageCalc What the data says
Electrical system accounts for about 39% of this year's Jeep Gladiator complaints. That is a moderate concentration; worth knowing, but complaints are spread across several areas.
The 2021 model year contributes 40 complaints (29%). No single model year dominates, so this looks like a line-wide pattern rather than one bad year.
Complaints are essentially flat year over year (149 to 136, -9%), in line with a market that rose about 2%. Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Jeep Gladiators are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.
