2016 Toyota Corolla

Purchased set of 4 Cooper CS5 Ultra Touring 195/65R1591H tires on 26 Jun 2026 @ 48,847 miles on the odometer. Three of the tires had the same serial number of U9AE1CR2622, with the 4th of U9AE1CR4822. Brought car in for service on 20 Oct 2025 @ 65,340 due to a slow leak on the rear passenger and was informed the rear passenger and front driver tires had tread separation and needed replacing. The tires both had a serial number of U9AE1CR2622. Tires were replaced. 15 Aug 2026, the front driver tire (the remaining tire with the U9AE1CR2622 serial number; it had been rotated to that position during the 20 Oct 2025 service) the tire pressure indicator light came on and discovered a slight (~7 psi) drop and aired up to correct pressure. However the tread appears rounded as apposed to flat across like the other tires and have confirmed the tread has separated. The car is driven moderately on paved roads and does not sit for extended periods of times. The tread depth is still quite deep. I expected much more out of these tires and do not plan on buying Cooper again. I believe the Cooper CS5 Ultra Touring 195/65R1591H tires (and perhaps more specifically, the U9AE1CR2622 batch) is defective and dangerous.

The CVT transmission on my 2016 Toyota Corolla initially suffered a complete mechanical failure and was repaired on 01/08/2024, forcing me to pay $3,696 out of pocket for a replacement at an independent shop. Last week, the transmission experienced issues again, and this time a certified Toyota dealership serviced it for free under an active factory recall. This proves the vehicle has a documented factory defect. However, Toyota is currently refusing to reimburse me for the original $3,696 repair expense incurred due to this exact defect.

The factory-applied Super White (paint code 040) paint on my vehicle has peeled down to bare metal on multiple exterior body panels. The peeling is not the result of any collision damage, scratches, or external trauma — it is consistent with the known factory paint adhesion defect that Toyota itself acknowledged through Customer Support Program ZKG, which covered this exact vehicle model, year, and paint color. Toyota's own program documentation states the defect occurs when sunlight degrades adhesion between the factory paint primer coat and the base metal electrodeposition layer. With paint peeled to bare metal, the affected panels are now exposed to moisture and the elements, creating a risk of structural rust and corrosion over time. I purchased this vehicle used in 2023 and was never notified of the Customer Support Program. By the time I discovered the program existed, the coverage had expired. Toyota has declined to provide any assistance. Toyota acknowledged this as a manufacturing defect affecting approximately 1.74 million vehicles under Program ZKG. Owners of 2016 Corollas who purchased their vehicles used were not adequately notified, and coverage has now lapsed for recently expired vehicles despite the defect being identical to those Toyota previously covered. I am requesting that NHTSA investigate whether Toyota's Customer Support Program ZKG adequately covered all affected vehicles and owners, and whether an expanded or extended remedy is warranted.

I was driving on the highway and the transmission gave completely out!! with no warning! No check engine light no error message. Car only has 160000 miles on it, if i wasn't calm as I was that could've been lethal!!!!

I have super white (040) paint and it's flaking off due to original manufacturer paint defect. Paint is flaking off my passenger back door and a large piece/area of roof. flakes of paint will come off at highway speeds, creating a vision hazard for drivers behind me or a distraction when flakes hit the windshield.
