Kestrel Take
Nine complaints and no recall campaigns on file. That is a very thin record, and it means few people wrote to NHTSA about this year — it is not a reliability rating and we will not dress it up as one. What is in there matters: three owners describe the car hesitating and revving when they pull into traffic, and three describe the brake booster failing, one of them repeatedly over three years. Both of those are the same faults the 2016 and 2017 Sparks are full of, and the 2018 carries the same 1.4-litre engine, the same CVT and the same brake vacuum setup, so assume the mechanism is shared and test for it rather than trusting the small number.
What we checked
Checked against public records, 2026-09-25
NHTSA holds 9 owner complaints for the 2018 Chevrolet Spark, and no recall campaigns.
That is too small a record to read a pattern from, so we are not going to pretend otherwise — with numbers this low one owner moves the percentage by a lot. What has been filed is grouped under throttle and cruise control (3), the engine (3), the brakes (3). Treat those as things to look at, not as the vehicle's known weaknesses. A thin file usually means few of these were sold or few owners filed. It is not evidence the vehicle is trouble-free, and the issues below are our own research rather than a reading of this record.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
Known Issues for the 2018 Chevrolet Spark
Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.
The same three filings appear under both the speed control and engine headings, which is why this one cluster is a third of the whole year's record twice over. Owners describe pulling into a gap or across a turning lane and having the car sit and rev before it decides to go, or pick a ratio far too tall or too short for the speed. Some of that is how this CVT behaves cold; the rest is a unit that needs fluid and a software check. Drive it from four or five standstills, including one uphill, and count the seconds before it actually moves.
Repair cost (estimate): $0–$300 for a fluid service and a transmission software check; four figures if the unit itself is worn
Source: NHTSA complaints filed under throttle and cruise control (3), the engine (3).
One owner had the brake booster repaired at a dealer yearly and had it fail again, and another says the brakes have simply gone out three times in three years, at freeway speed, with no warning light beforehand. On this generation the assist depends on an engine-driven vacuum pump, and that is where the 2016 and 2017 Sparks trace the same complaint. Do the standing test: engine off, pump the pedal until it is hard, hold it, start the engine, and feel whether the pedal falls away. A pedal that stays hard is the fault, not a quirk.
Repair cost (estimate): $300–$900 for the brake vacuum pump or booster fitted
Source: NHTSA complaints filed under the brakes (3).
Only two filings name the transmission on this year, which is too few to call it a pattern on the 2018 specifically. But it is the same Jatco-built CVT as the 2014 through 2017 cars, where the record is thick with lost drive and replacement units, and a replacement costs close to half what a clean 2018 sells for. Get the fluid checked for smell and colour, drive it long enough to warm through, and treat any shudder at a steady 20 to 25 mph as a reason to walk rather than to negotiate.
Repair cost (estimate): $3,200–$4,800 for a replacement CVT at a dealer, less with a reconditioned unit — around 56% of what this car is typically worth

Walk-Away Red Flags
- ✗A pause and a flare of revs before the car moves off
- ✗A brake pedal that stays hard when the engine starts
- ✗Shudder at a steady 20 to 25 mph
