Mileage counters do not always tell the real story, and plenty of cars start causing trouble long before they reach middle age. The entries below draw on owner complaint records that log when each problem appeared and what the repair averaged. Here are eleven vehicles that ran into costly problems before 40,000 miles.
1. 2019 Toyota RAV4: Hesitating Hard At Walking Pace

Owner reports compiled in the CarComplaints Toyota listings put a hesitating, lurching RAV4 at an average of just 3,000 miles, with an average repair bill of $20,000. That is the earliest and most expensive entry on this list, and it sits on a mainstream compact crossover.
Anyone shopping this generation should test-drive it at parking-lot speeds and ask the dealer for the service history. A complaint database reflects owner reports, not recall data, so treat the figure as a warning flag rather than a verdict on every unit.
2. 2013 Hyundai Elantra: Mileage Far Below The Sticker

The Hyundai complaint records show the top Elantra gripe is fuel economy nowhere near the EPA figure, appearing at an average of 10,000 miles. No dramatic breakdown is involved, just a steady gap between the window sticker and the pump.
A buyer who relies on the rated mpg for budgeting should log real fill-ups during the first few thousand miles. A persistent shortfall is worth documenting early, while the car is still well inside its warranty coverage.
3. 2015 Jeep Grand Cherokee: Shifter Trouble At 12,000 Miles

Unreliable electronic shifting is the headline complaint in the Jeep complaint listings, averaging $7,500 to sort out at around 12,000 miles. The Grand Cherokee’s shift-by-wire setup has no direct mechanical link, so a fault can leave the driver without a dependable gear selection.
Any odd shifter behavior, such as the wrong gear engaging or a delayed response, deserves a dealer visit right away. Waiting until the warranty period ends can turn a repair covered at no charge into a bill in the thousands.
4. 2019 Volkswagen Jetta: Grinding Before 17,000 Miles

A grinding noise from the transmission is the worst-rated Jetta problem in the Volkswagen owner complaints, reported at an average of 17,000 miles and averaging $26,000 to fix. That repair cost is the highest figure anywhere on this list.
The number likely reflects full transmission replacement, so a prospective buyer should listen for grinding on a long test drive. Paperwork showing prior transmission service is a useful point in favor of any used example.
5. 2015 Nissan Murano: Jerking Through The Gears

Jerking is the Murano’s worst-rated fault in the Murano complaint page, with owners reporting an average repair cost of $6,500 at about 21,000 miles. The complaint points toward the drivetrain rather than a cosmetic or comfort issue.
Used shoppers should drive the car through a full range of speeds and watch for surging or hesitation. Because this SUV’s repair average is steep, a pre-purchase inspection costs little compared with the potential bill.
6. 2017 Chevrolet Silverado 1500: Surging At 22,000 Miles

Surging and jerking tops the whole Chevrolet list in the Chevrolet complaint listings, averaging $4,100 at around 22,000 miles. That is notable because the Silverado 1500 is one of the best-selling pickups, so the issue touches a large pool of owners.
Truck buyers should confirm that any open transmission bulletins or recalls have been completed on a specific VIN. Towing and hauling put more strain on a drivetrain, which makes early symptoms worth reporting promptly.
7. 2014 Ford Focus: Stop-And-Go Shudder

Bad hesitation and jerking from a stop is the Focus complaint highlighted in the Ford complaint records, averaging $1,200 at 25,000 miles. Compared with the rest of the list, the bill is modest, yet the symptom appears in everyday traffic.
A shopper should test this car from a dead stop repeatedly, including in slow traffic, since the fault shows up at low speed. A repair history showing the issue was addressed is a strong point in a used example’s favor.
8. 2011 Buick LaCrosse: The Light That Won’t Quit

An engine light that keeps coming on is the LaCrosse entry in the Buick complaint listings, averaging $6,500 at about 26,000 miles. A recurring warning lamp can point to many underlying faults, which helps explain the high average repair cost.
A recurring light is easy to dismiss, but a shopper should scan for stored codes before buying. Repeated visits for the same lamp are a sign that the root cause may never have been properly found.
9. 2015 Nissan Rogue: Climate Control Gives Out

A/C and heater failure is the Rogue complaint in the Rogue owner reports, averaging $2,200 at roughly 32,000 miles. It is not a safety fault, but losing cabin heat or cooling is a costly annoyance on a car this young.
Buyers should run both heat and cold for several minutes during a test drive and check airflow from every vent. Climate repairs can be expensive because dashboard components are often involved, so an early check is worthwhile.
10. 2014 Subaru Forester: Thirsty For Oil At 33,000 Miles

High oil consumption is the Forester’s worst-rated problem in the Subaru complaint listings, logged at about 33,000 miles. Burning oil that early matters because an engine run low can suffer serious, expensive damage.
Owners should check the dipstick between changes and note how much is added. A buyer can ask for oil-consumption records or a documented consumption test, and a car that needs frequent top-ups between changes is a better candidate to skip.
11. 2011 Chevrolet Cruze: Sweet Smell In The Cabin

An antifreeze smell inside the car is the Cruze complaint in the Cruze complaint page, averaging $1,300 at around 33,000 miles. The odor usually signals a coolant leak, often near the heater core, and the problem arrives just before many warranties end.
A sweet odor, foggy windows, or a dropping coolant level should lead to a same-week inspection. Ignoring a leak risks overheating, so the cost of acting quickly is small compared with engine damage.
