Kestrel Take

The 2018 carries the same two faults as the 2017 — the battery control module and the "Shift to Park" nonsense — but in a noticeably calmer record: 222 complaints against the 2017's 697, and no fire reports at all. It also has two recalls the 2017 does not, both cheap to close and both worth confirming. If you are choosing between the two years, this is the better bet, but not because the faults went away; they did not. The purchase still turns on one question, and it is the same one: has this car's Battery Energy Control Module been replaced, and is there paper to prove it? The 8-year/100,000-mile propulsion coverage runs out right about now, so being a year out of luck costs real money.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 222 owner complaints for the 2018 Chevrolet Volt, and 2 recall campaigns.

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. 39% of them are about one thing — electrics and electronics. 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.

2 recall campaigns cover 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.

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

Known Issues for the 2018 Chevrolet Volt

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

Battery Energy Control Module failure — reduced propulsion, then the car stopsHigh — wallet impact

Owners describe a "propulsion power limited" warning and a check-engine light, then "Engine unavailable", then a car that shuts off — on an interstate on-ramp, on a road trip, in heavy city traffic where one driver's speed fell to 5 mph with a child aboard. The word BECM appears 43 times in this cluster alone. A Chevrolet dealer can tell you whether the propulsion coverage is still live on this VIN and whether the module has been replaced already; treat that answer as the price of the car.

Repair cost (estimate): $1,800–$3,000

"Action Required: Shift to Park" — the car will not accept that it is parked or switch offMedium

Thirty-eight percent of this car's complaints are this one message. The shifter is in park, the power button does nothing, and the screen demands you shift to park; owners clear it by squeezing the shifter trigger repeatedly, and it comes back. Two consequences matter: you cannot lock and leave the car, and it sits awake overnight flattening the 12-volt battery. One driver reports the message appearing at interstate speed and coasting to a stop. Chevrolet has published more than one bulletin on it; ask whether any of that work was done. Shut the car off several separate times during your visit.

Repair cost (estimate): $300–$700

Source: NHTSA complaints filed under the transmission and drivetrain (84).

No drive when you select a gear, and cold-weather fault codes at startupHigh — wallet impact

Distinct from the reduced-power pattern and more frightening: the car appears to wake up, you select reverse, and there is no motor power at all — one owner rolled backwards down their own driveway before the engine caught. Others report warning lights after a cold remote start around freezing, with OnStar reporting stored powertrain codes. A tired 12-volt accessory battery causes some of this and is cheap; the high-voltage control module causes the rest and is not. Ask for a 12-volt load test and a full code scan before you agree a price.

Repair cost (estimate): $200–$400 for the 12-volt battery; $1,800–$3,000 if the high-voltage control module is at fault

Rear brake calipers may have too little corrosion protection, weakening braking (recall)High — wallet impact

Recall 18V576000 covers a long list of 2018-2019 GM cars including the Volt: the rear brake caliper pistons may have insufficient coating, which can reduce braking performance. The remedy is simply bleeding the brake system, free at a dealer — one of the cheapest safety recalls GM has ever issued to close, and no excuse for an open one eight years on. Check the VIN on NHTSA's free lookup and ask when the brake fluid was last changed while you are at it.

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

Rear seat belt retractors may not lock for a child seat (recall)Medium

Recall 18V673000 covers 2018-2019 Volts among other GM vehicles: the rear seat belt retractor may not automatically lock when the belt is pulled all the way out, which is the mechanism that holds a child seat tight. Dealers inspect and replace free. This one matters only if you carry children, but it matters a lot then. Pull each rear belt fully out and let it retract — it should click into a locked mode at full extension.

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

Walk-Away Red Flags

✗"Shift to Park" appearing even once while you are there
✗Reduced propulsion or "Engine unavailable" on the test drive
✗Hesitation or nothing at all when you first select drive or reverse
✗Seller who has owned it long enough to know the module history but will not say

Good Signs

✓Battery Energy Control Module replacement invoice with a date and mileage
✓Both recalls shown closed on the NHTSA VIN lookup
✓Rear belts that lock audibly when pulled fully out
✓Four clean shutdowns in a row with the shifter in park
✓Chevrolet service history showing the propulsion warranty was used
