Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2018 Chevrolet Corvette shows a notable improvement in complaint volume compared to its immediate predecessors, dropping to 51 complaints from 255 in 2017, while also experiencing only 1 recall versus 4 the prior year, though complaints rose again to 147 in 2019. Within this generation's arc, 2018 represents one of the lowest complaint years recorded, falling between the elevated 2017 period and the subsequent 2019 uptick. The data reveals that wheel-related issues dominate the 2018 record, comprising 43 of the 51 total complaints (approximately 84%), with only 1 crash complaint and zero fire complaints recorded. This concentration suggests the low overall complaint count may reflect a specific component concern rather than broad reliability, though it is worth noting the single recall addressed a discrete issue. Given the low complaint tally, minimal recall activity, and absence of investigations, the 2018 model year appears to be among the more favorable used Corvette options within this generation.
