Toyota carries a reputation for durability, yet owner complaint records show that no brand escapes expensive trouble. Oil consumption, rust, and transmission failures recur across several of its best-known nameplates, and the costs vary widely by model year. Here are twelve Toyotas that collected the most owner complaints, with the worst years and priciest repairs for each.

1. Toyota Camry: Oil Use Leads Camry
The Camry draws 3,617 complaints, the most of any Toyota, and the Camry complaint page rates 2008 its worst model year. Oil consumption fixes in that year averaged $2,700 at 107,000 miles.
High total counts partly reflect how many Camrys were sold and driven. Even so, anyone shopping a 2008 should check oil level history and ask whether the engine has already been repaired. Complaint totals reflect owner reports, so they follow sales volume as well as reliability.
2. Toyota RAV4: A Costly Oil Habit
The RAV4 has 2,666 complaints, and its 2008 model tops the site’s cost list. CarComplaints’ Toyota page records excessive oil consumption fixes averaging $35,600 at 105,000 miles, plus a 2019 lurching complaint averaging $20,000.
Those averages come from a small number of reports, so a single large bill can lift them considerably. The figures still show how severe the worst cases can get, and why oil checks matter on older examples. Records of past repairs matter more than the model’s overall reputation.
3. Toyota Corolla: Thirsty Early Engines
The Corolla has 1,568 complaints, with the 2002 model year rated worst. The Corolla complaint page lists engines using excessive oil as the problem, a repair averaging $2,500 at 99,000 miles.
Oil consumption comes up again here, hinting at a recurring weakness in certain Toyota engines of that era. Owners of an older Corolla can head off trouble by watching the dipstick between changes. Reading the model-year pages gives a clearer picture than the brand average alone.
4. Toyota Prius: Hybrid With Oil Woes
The Prius has 1,530 complaints, and 2011 is rated its worst year. CarComplaints’ Prius page shows excessive oil consumption in that model averaging $3,000 to fix at 113,000 miles.
Hybrid ownership is often assumed to mean fewer engine headaches, but the combustion engine still needs lubrication. A used 2011 deserves a close look at oil records, not just battery health. A pre-purchase inspection by an independent mechanic is inexpensive insurance.
5. Toyota Tacoma: Paint Peels Away
The Tacoma has 1,174 complaints on CarComplaints, and 2005 is rated its worst year. The Tacoma complaint page lists paint peeling as the leading problem, costing an average $3,300 to fix at 101,000 miles.
Cosmetic faults rarely stop a truck from running, yet repainting can cost as much as a mechanical repair. Inspect the finish carefully on any older Tacoma, since large flaking areas are hard to hide. Maintenance records help separate sound examples from ones with a troubled past.
6. Toyota Sienna: Power Loss Hits Early
The Sienna has 1,002 complaints and a worst year of 2007. The Sienna complaint page points to loss of power after slowing down, a problem that averaged $3,000 to fix at just 37,000 miles.
Such low mileage means the fault tends to appear while a van is still young. Families considering a 2007 should confirm whether the repair was done and whether the work carried any warranty. A thorough test drive helps reveal problems before any money changes hands.
7. Toyota Highlander: Stripped Bolt Threads
The Highlander has 821 complaints, with 2003 rated worst after stripped engine-bolt threads averaging $3,200 to fix at 123,000 miles. The Highlander complaint page also lists a 2017 transmission failure averaging $8,600.
The newer failure is the pricier of the two and arrived at a modest 57,000 miles. Buyers of recent used examples should not assume that age alone separates the costly cases from the cheap ones. Comparing several model years on the site helps pinpoint which ones to avoid.
8. Toyota 4Runner: Rust And Airbag Concerns
The 4Runner has 652 complaints, with 2005 rated its worst year for undercarriage rust costing about $2,000 at 140,000 miles. CarComplaints’ 4Runner page also lists a 2015 airbag failure to deploy averaging $9,000.
Rust is a concern for any older truck-based SUV, particularly in regions that salt roads. A frame and underbody inspection should come before purchase, and airbag complaints deserve follow-up with a dealer. Owner narratives on the site add detail that the headline totals cannot capture.
9. Toyota Avalon: Only A Headline Count
The Avalon has 590 complaints on file, according to the Toyota brand page at CarComplaints. That total places the full-size sedan well below the Camry and the RAV4 on the same list.
The source offers only the count here, with no worst year or repair figure. Prospective buyers wanting more can consult the model’s own pages, since a raw total says little about which years carry risk. Cross-checking recall status for the exact vehicle identification number is wise.
10. Toyota Tundra: Pump Repair Pricey
The Tundra has 547 complaints on CarComplaints, with 2012 rated its worst year. The Tundra complaint page lists an air induction pump repair in that model averaging $2,900 at 78,000 miles.
The pump is part of the emissions equipment, so a failure can bring dashboard warnings long before drivability suffers. Owners of a 2012 should ask whether the repair has been done on a used truck. Service records showing prior repairs make a used example far easier to judge.
11. Toyota Sequoia: Transmissions Give Out
The Sequoia has 339 complaints, led by 2002 models. CarComplaints’ Sequoia page lists transmission failures from that year averaging about $3,500 to fix at around 97,000 miles.
A transmission repair is among the larger bills an SUV owner faces. Anyone eyeing a first-generation Sequoia should look for fluid service records and test shifting carefully, including on hills and in stop-and-go traffic. Pricing in a reserve for major repairs, especially on high-mileage examples, keeps ownership costs predictable.
12. Toyota Yaris: Light On Detail
The Yaris has 237 complaints on file, according to the Toyota brand listing at CarComplaints. That makes it the lightest complaint load among the twelve models in this gallery.
Only the total is available, so no worst year or repair cost can be cited. A small count is encouraging but not conclusive, since fewer sales also mean fewer owners who might file a report. A broader look at model-year pages would fill in what this single count leaves out.
