  • Extremely expensive and scarce replacement parts — taillight assemblies cited as costing over $2,000 USD each, with other unique components (adaptive headlight motors, hardtop hydraulics) being rare and costly. Frequency: very frequent.
  • Northstar V8 engine concerns — historical reputation for head gasket failures, oil leaks, and general unreliability in early iterations; later models (post-2004) noted as improved but still a source of anxiety; widely criticized as underpowered (320 hp) compared to Corvette's LS engines. Frequency: very frequent.
  • Retractable hardtop mechanism failures — hydraulic pump and motor issues leading to inoperable roofs; parts are difficult to source. Frequency: recurrent.
  • Adaptive headlight system failures — motors that turn the headlights fail; units become foggy/faded and are prohibitively expensive to replace. Frequency: recurrent.
  • Electrical gremlins and accessory failures — various electronic issues reported as common in aging examples. Frequency: recurrent.
