Verbatim from NHTSA complaints, newest first
“The vehicle contains a known manufacturing defect where the engine coolant bypass valve cracks internally, leaking pressurized fluid directly into the main electrical connector (covered under Toyota CSP 24TE04). This fluid intrusion has caused active electrical short-circuits to the battery and ground networks. As a direct result of this progressive component failure, the vehicle is actively dropping into 'Limp Mode' and experiencing severe transmission shifting failures while being driven on public roads, creating an immediate safety and crash hazard. Furthermore, a franchised Toyota dealership actively turned away an attempted preventive repair under the 'Prior Sought Remedy' rule while the vehicle was under the 100,000-mile warranty threshold, stating the dashboard light had to be on first, which directly allowed this hazardous electrical degradation to progres”
“Went in to get a service done for my vehicle and all the highlighted areas were the problem. They stated models from 2019-2022 The Camrys all have had transmission issues. I still have my car and it’s working, but I don’t want to pay for a new transmission when Toyal manufacturing has been aware of these models and issues.”
“Transmission began failing. Whining coming from transmission when accelerating and shifting becoming more rough. Dealership said transmission is failing and needs to be replaced. Mileage is at 89,000 miles. Rough shifter made it dangerous to drive on the highways. Was inspected by warranty adjuster. No warning lamps or lights ever appeared.”
“This 2020 Camry's transmission will be fine and then when you let off the throttle it will begin to slow as it should. However, when you reapply the throttle the transmission slams very forefully into gear and jolts the car forward violently. Idl'd heard about this on numsrous Camry's before, but until I owned one I had no idea how bad this is... it is not safe. Toyota needs to correct this problem for all their vehicles.”
“The check engine light illuminated on my 2020 Toyota Camry XSE 2.5L with approximately 132,798 miles. An OBD2 scan revealed fault code P26AE — Engine Coolant Bypass Valve 'B' Control Circuit High. This is a known widespread defect affecting 2018-2022 Toyota Camry, RAV4, and Corolla vehicles equipped with the 2.5L Dynamic Force engine. The plastic valve casing is prone to cracking, allowing coolant to seep into the electrical connector and corrode the pins, triggering the fault. Toyota has acknowledged this issue through a Customer Support Program offering free replacement on qualifying vehicles, however many owners are still being quoted $900-$1,300 at dealerships. The faulty valve affects the engine coolant flow control system and transmission cooling circuit. Warning light appeared suddenly after a routine fuel fill. Vehicle has not yet been inspected by dealer. Component is available for inspection upon request."”
“I purchased my vehicle from a certified used car dealership in Connecticut in 2020 with a little over 1800 miles. Since purchasing the vehicle, it has been very reluctant to down shift and had slight transmission whine. I was notified of a recall for I believe the TCM a few months after purchasing it, which i had remedied by the dealership. Over the years, my car has been maintained completely to Toyotas manufacturer standard. Around 50,000 miles i started experiencing shuddering during shifts and slipping during shifts and a louder whine Around 89,000 miles my transmission symptoms worsened. Sporadic shifting, obvious whine, grinding and clunking during shifts and shifting between gears, and clicking from a stop. At 97k i serviced the transmission fluid which seemed to help a little bit but did not get rid of the symptoms fully. The fluid was dark brown, which was serviced 3,000 miles before Toyotas recommended interval. I then replaced the driver side cv axle shaft which also did not remedy any symptoms and i was notified by my shop that it was premature transmission failure. Now at 100,998 miles, my transmission grinds and clunks during all lower gear…”
