Chart is based on 2516 vehicles in TrueDelta's reliability survey.
These are the problems owners most commonly reported on TrueDelta's Car Reliability Survey. For many models not all entries have been coded yet, so focus on the relative numbers rather than the absolute numbers. Usually when people say "they all have this problem," the problem in question actually affects between 10 percent and 20 percent of all cars. We aren't counting wear items like brake pads and rotors that truly do require periodic replacement on all cars.
