In the sample of engine complaints we read, owners describe several things. Three talk about oil use or low oil. Four name a vacuum pump, camshaft part or vacuum leak. Four describe stalling, hesitation or losing power at a stop. Two say the engine was replaced after a failure[3]. One describes a fire in a car that was turned off[3].

Exterior lighting. There are 8 complaints, with no crashes, fires or injuries[4]. In the sample we read, seven of the eight describe water or moisture inside a headlight housing, often on the driver side. One describes dim back-up lights[4].

Electrical system. There are 5 complaints and 2 injuries[8]. In the sample, two describe doors that stayed locked with people inside, and two describe the dashboard or radio going dark while driving[8].

Fuel and propulsion. There are 4 complaints, with 1 crash and 1 injury[9]. The sample is mixed. One owner says the emergency fuel shut-off did not work after a collision[9]. The other texts cover rough idle, oil burn and a warning light, one each[9].

Air bags (3), visibility and wipers (2) and electronic stability control (2) have very few complaints[10][11][12]. We do not treat them as common problems.

Complaints submitted to NHTSA by owners; unverified reports, one complaint can name several components. Complaint counts are not normalized by sales; compare years of the same model, not different models. EPA annual fuel cost uses EPA's current fuel price assumptions, not the price when the car was new. Horsepower is the rating listed for EPA test vehicles. Dimensions are Canadian-market specifications and can differ slightly from US models.
