If either diameter is less than 11.3 mm (0.445 in), Do not reuse old bolts. Use new bolts coated with clean engine oil. Tighten all bolts to finger tight then continue on with the following procedure.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2006 Civic Hybrid represents a dramatic inflection point in this generation's federal record, with complaints surging from 48 in 2005 to 1,457 — roughly a thirtyfold increase — alongside recalls jumping from 6 to 17 and technical service bulletins more than doubling to 107. This pattern is consistent with a major redesign year introducing multiple systemic issues, and the complaint volume remains elevated for several model years afterward (1,267 in 2007, 979 in 2008) before gradually declining to a low of 166 by 2011, suggesting the underlying problems were progressively addressed over the production run. The 2006 model's top complaint areas — Visibility (195), Engine (193), Air Bags (155), and Suspension (148) — are broadly distributed, indicating no single isolated defect but rather widespread teething issues across multiple vehicle systems, and the 81 crash-related and 21 fire-related complaints further underscore the severity. Notably, investigations dropped from 4 in prior years to 1 in 2006, though the data does not specify why; it does not identify root causes for any of the complaint categories. The 2006 model sits squarely at the peak of the generation's problem arc, making it the least desirable year to purchase. A used 2006 Civic Hybrid is a poor choice relative to later years in this generation — buyers should strongly prefer 2009 or later models, by which point complaint volumes had fallen to roughly a quarter of the 2006 peak.
