Kestrel Take

Fifty-one complaints, and 45 of them are wheels — the same cracked rears and bent fronts that dominate the 2017 record, on the last of the C7 run. That is a thin file overall, which reflects how few of these were built and how gently most are driven, not a reliability grade. The one safety campaign on the record is the 2025 electric power steering gear replacement, which is free but often still open on cars that changed hands. So: read the rims on a lift, run the VIN, and drive it cold to feel the eight-speed for yourself. Do those three things and this is a good car to own.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 51 owner complaints for the 2018 Chevrolet Corvette, and 1 recall campaign.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 88% of them are about one thing — wheels and bearings. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

One recall campaign covers this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Looked at and set aside: the brakes (2) — Two complaints total. One is a pedal that went to the floor repeatedly and is logged with a crash; the other is rust banding on the rotors that scored the pads, which GM called cosmetic. Two filings with two unrelated causes is not a pattern we can write up as a defect of this year. Check pedal firmness and rotor surface on the test drive as you would on any car; electrics and electronics (1) — A single complaint, from a buyer whose trunk popped open when he sat down and who heard a popping noise reversing under lock. One filing is one car, and a trunk latch switch is a cheap part. There is nothing here that tells you anything about the 2018 as a model year, and nothing worth pricing into an offer.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2018 Chevrolet Corvette

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Original wheels crack at the rim lip and bend at the front — 88% of the filingsHigh — wallet impact

Forty-five of this year's fifty-one complaints. Owners describe a rear tire that keeps losing air, then a tire shop finding cracks along the lip, and often bent front rims discovered at the same visit — several cars under 10,000 miles. GM declined most of these under the bumper-to-bumper warranty as pothole damage, and at least one owner had cracked rims welded and kept losing air afterwards. The check is five minutes on a lift: run a finger around the inside of each rim and look for weld beads that say it has happened before.

Repair cost (estimate): $600–$1,800 per wheel, at the top end for the Grand Sport and Z06 rears

Source: NHTSA complaints filed under wheels and bearings (45).

Electric power steering gear replacement campaign, notified in 2025High — wallet impact

Campaign 25V175000 covers 2016-2018 Cadillac CTS and 2017-2018 ATS, Camaro and Corvette: the electric power steering assist can fail, leaving you pushing a heavy wheel exactly when you need it most, at low speed in a turn. Dealers replace the steering gear assembly free of charge and owner letters went out in April 2025 — which is recent enough that plenty of used cars on the market have not had it done. Check the VIN on NHTSA's lookup and, if it is open, book it before you drive the car far.

Repair cost: $0 with the recall — verify it was performed

8L90 eight-speed shudder is a C7 pattern worth a cold test drive, even though this year's file is quietMedium

Only one powertrain complaint was filed on the 2018, which is not the same as the transmission being different — this is the same 8L90 automatic that draws the largest complaint cluster on the 2015 Corvette. The symptom is a shiver at a steady 40 to 70 mph under light throttle, and it is fixed with GM's revised transmission fluid and a calibration before it becomes a torque converter. We are listing it on general knowledge of the gearbox rather than on this year's record; drive the car from stone cold and judge for yourself.

Repair cost (estimate): $500–$1,200 for the revised-fluid service and reflash

Walk-Away Red Flags

✗A single tire that needs air more often than the other three
✗Cracks or weld repairs visible on the inner lip of a rim
✗Power steering warning message in the history, or heavy steering at parking speed
✗A vibration at a steady 40–70 mph under light throttle
✗Seller who cannot say whether the 2025 steering recall was done

Good Signs

✓Recall 25V175000 shown closed on the NHTSA VIN lookup
✓Replacement wheels fitted, with the invoice to prove it
✓Transmission fluid service on record with GM's revised fluid
✓Even tire pressures across all four wheels after sitting overnight
✓Brake rotors with a clean, even wear face and a firm pedal on the first stop
