On the 2012 Toyota Highlander Hybrid, the failure owners report most often is other body or interior problem, with 3 reports on file. Across every failure mode on this year, half the dated reports were filed before 85,000 miles.
What owners report breaking
Owners have reported 7 named failure modes on the 2012 Toyota Highlander Hybrid, and the three most-reported carry 55% of everything filed.
Other body or interior problem leads with 3 reports and about 0.1 per 1,000 vehicles.
Sunroof failure or glass breakage follows with 2 reports, median 105,000 miles.
CV axle or driveshaft failure follows with 1 report, median 25,000 miles.
By system, the reports fall mostly into body (5), drivetrain (1) and fuel (1).
The mileage the reports cluster at
11 of the reports on the 2012 Toyota Highlander Hybrid came with an odometer reading, and half of those were filed before 85,000 miles.
Cumulatively, 27% by 50,000 miles and 55% by 100,000 miles of the dated reports had been filed.
The busiest stretch is between 80,000 and 90,000 miles, which alone holds 27% of the dated reports.
27% of the dated reports were filed below 36,000 miles.

What happens when these parts fail
Nothing in the reports on the 2012 Toyota Highlander Hybrid mentions a crash, a fire or an injury. That is the ordinary case and it is worth stating: most defect complaints are about a car that stopped working, not one that hurt somebody.
The average severity weight across every report on this year is 3.45, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other body or interior problem at $200–$2,000, sunroof failure or glass breakage at $700–$4,500, CV axle or driveshaft failure at $450–$2,200 and fuel tank, filler or EVAP failure at $250–$1,800. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
9% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.
Every reported failure mode

|---|---|---|---|---|---|---|---|---|---|
| Other body or interior problem | body | 3 | 3 | — | 103k | — | 0.1 | $200–$2,000 | Moderate |

This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2012 Toyota Highlander Hybrid draws about 0.3 per 1,000 vehicles, which puts it in the 73rd percentile of complaint rates among 2012 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model.
The working figure is 43,197 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2012 vehicles, which is what the risk score uses, is far more robust than the rate itself.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.
Other body or interior problem
Several small paint bubbles on rear hatch. One had burst at seam of trim and is rusting. Screws holding the license plate light and assembly are rusted. Underside of "highlander" emblem trim where rear camera is located is corroded and rusted. *tr
CV axle or driveshaft failure
The vehicle was taken into dealer for a factory recall to replace the rear driveshaft assembly. The car was driving completely normally when taken in for this service. But when picked up, the car was unsafe. It drove normally at low speeds leaving the dealership. But a couple of miles later when getting onto the freeway, at about 50 MPH, the rear end started to feel like it was a drag on forward movement, and felt like it was swaying from side to side, making the vehicle very difficult to control. No unusual noises were heard. Emergency flashers were activated and speed reduced to 25 MPH to try to maintain control of the vehicle. The first off ramp was taken, and the dealer notified. The car was towed back to the dealer, who kept it for the next 36 hours. The dealer reported no problem could be found, and no repair had been done. The vehicle has driven completely normally again since then. *tr
How 2012 compares with the other years
Across the 6 model years of this car that carry enough reports to score, 2021 comes out best at 64 and 2006 worst at 68.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
What this page cannot tell you
11 owner reports; fleet size borrowed from other years of the same model. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 11 reports, 11 carried an odometer reading, so the mileages here describe 100% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 2012 Toyota Highlander Hybrid?
The most-reported failures are other body or interior problem (3 reports, median 105,000 miles), sunroof failure or glass breakage (2 reports, median 105,000 miles) and cv axle or driveshaft failure (1 report, median 25,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
