On August 5, 2024, plaintiff Jessica Huang purchased a 2021 Toyota RAV4 from Pacific Coast Motors (a licensed used car dealership in Portland, Oregon) for $28,500. The vehicle was listed as "Certified Pre-Owned, 120-point inspection passed, 90-day powertrain warranty." On August 29 — 24 days after purchase — the transmission began slipping violently while Huang was driving on I-84 at highway speed, nearly causing a rear-end collision. She had the car towed to an independent mechanic who diagnosed a failing torque converter and worn clutch packs. Repair estimate: $4,800. Huang immediately demanded a full refund under Oregon's Used Car Lemon Law (ORS 646A.402), which allows rescission if a substantial defect manifests within the warranty period and cannot be repaired in a reasonable time. Pacific Coast Motors refused, arguing: (1) the defect was caused by Huang's "aggressive driving" during the 24 days; (2) their 120-point inspection showed no transmission issues; (3) they offered to repair the vehicle rather than refund it. Huang rejected the repair offer and filed suit seeking: full purchase price refund ($28,500), towing costs ($385), independent mechanic diagnostic fee ($275), and attorney fees. Pacific Coast counter-claims Huang voided the warranty by failing to bring the car to their authorized service center first.
Vehicle listing and sales contract
Online listing: "2021 Toyota RAV4 XLE AWD, 38,241 miles, Certified Pre-Owned, 120-point inspection PASSED, clean Carfax, 90-day/4,500-mile powertrain warranty included." Sales contract signed August 5, 2024 includes Addendum C: "Powertrain Warranty — covers engine, transmission, transfer case, and differential for 90 days or 4,500 miles from date of sale. EXCLUSION: Damage caused by misuse, racing, or failure to maintain." Key dispute: what constitutes "misuse" is undefined in the contract. The listing also states "clean Carfax" — but the Carfax report actually shows one prior service record flagging "transmission fluid dark, recommend monitoring" from 14 months before the sale.
Pacific Coast Motors 120-point inspection report
Dated August 2, 2024 (3 days before sale). Performed by dealership technician Brad Kowalski. Transmission section: "Fluid level: OK. Fluid color: acceptable. Shift quality: smooth. No codes present." No test-drive record attached. Plaintiff argues: a visual fluid check and code scan cannot detect a failing torque converter — a proper inspection requires a road test and fluid sample analysis. Defense argues: the inspection followed industry-standard procedures and the vehicle showed no symptoms on August 2.
Independent mechanic diagnostic report (plaintiff's evidence)
Prepared by Green Valley Auto Repair (ASE-certified shop), September 2, 2024. Findings: Torque converter clutch material degradation, clutch pack wear exceeding service limits, metallic debris present in transmission fluid sample. Mechanic's opinion: "This level of internal wear is consistent with a pre-existing condition developing over thousands of miles. It cannot be caused by 24 days of normal driving (approximately 850 miles based on odometer). The transmission fluid sample shows contamination levels that would take 8,000–12,000 miles of operation to accumulate." Estimated repair: $4,800 (torque converter replacement + transmission flush). Defense objects: Green Valley is not a Toyota-authorized service center and the mechanic is not qualified to determine when the wear began.
Carfax vehicle history report
Report shows: 1 prior owner (lease return). Regular maintenance documented at a Toyota dealership. June 2023 service record entry: "Transmission fluid appears dark. Recommend monitoring at next service interval." No subsequent transmission service documented before the vehicle was traded in to Pacific Coast Motors in July 2024. Plaintiff argues this proves the dealer knew (or should have known) about a developing transmission issue before certifying the vehicle. Defense argues: "dark fluid" and "recommend monitoring" is a routine observation, not a defect diagnosis; the dealer purchased the vehicle at auction and may not have reviewed the full Carfax before listing it as "clean."
Huang's driving records and vehicle use documentation
Odometer at purchase: 38,241 miles. Odometer at breakdown: 39,087 miles. Total miles driven by Huang: 846 miles in 24 days (avg. 35 miles/day — normal commuter use). GPS data from Huang's phone shows routine trips: home to office (12 miles), grocery store, one weekend trip to Mt. Hood (124 miles). No evidence of racing, towing, or off-road use. Defense argues: highway driving (I-84 trips to Mt. Hood at elevation) can stress the transmission; plaintiff argues: manufacturer-rated highway driving is by definition normal use, and 846 miles cannot cause the documented wear patterns.

When I dropped the transmission pan, I found significant metallic debris — that tells me the torque converter has been shedding material for a long time. You don't get this level of contamination in 850 miles. This is thousands of miles of progressive wear. The fluid was dark brown and smelled burnt, which is consistent with overheating that pre-dates Ms. Huang's ownership. In my professional opinion, this vehicle should not have passed any legitimate pre-sale inspection.

I checked the transmission fluid level and color — it was within acceptable range on August 2. I scanned for diagnostic codes and got none. The car shifted fine when I moved it around the lot. Our 120-point inspection is the industry standard for used vehicles. I can't explain why the transmission failed 24 days later, but it was fine when I checked it. Sometimes things fail suddenly — that's why there's a warranty for repairs.

Based on the fluid sample contamination levels and the clutch pack wear measurements documented by Green Valley Auto, this transmission was in a state of progressive failure well before August 5, 2024. The metallic debris concentration in the fluid is not consistent with 850 miles of any driving style — normal, aggressive, or otherwise. That said, I cannot pinpoint with precision when the failure began. The June 2023 Carfax notation about dark fluid is a red flag that, in my opinion, should have prompted further investigation during the dealer's pre-sale inspection.
