2020 Toyota Camry XSE, VIN [XXX], 2.5L 4-cylinder A25A-FKS engine, built at Toyota Motor Manufacturing Kentucky (TMMK) during the production window covered by the federal safety agency Recall 20V‑064 (Toyota campaign 20TA04), which addresses porosity in engine castings that can cause internal and external coolant leaks, engine overheating, and possible engine failure. Toyota’s VIN lookup returns this vehicle as not affected by the campaign, but the failure pattern matches the recall defect exactly. Timeline of failures and repair attempts: XXX, at approximately 92,832 miles, Camelback Toyota in Phoenix, AZ (RO XXX). Check engine light active. Diagnosed DTC P268115 (Engine Coolant Bypass Valve Circuit, Short to Battery or Open). Battery also failed load test. Overheating symptom noted on the same repair order. Coolant bypass valve replacement recommended. Following that visit, water pump and thermostat were replaced at Berge Toyota (Mesa/Gilbert, AZ area). Camelback Toyota stated the vehicle was fixed. Vehicle overheated again the next day after being returned as repaired. XXX, at 93,034 miles, Camelback Toyota (RO XXX). Oil and filter change performed under good faith goodwill service, transmission fluid exchange completed. Overheating condition persisted. Vehicle continued to overheat through the summer and into September 2026. Current dealer now recommends head gasket replacement and states that if the head gasket does not resolve the overheating, the engine block is cracked and the engine will need replacement. Dealer describes the engine as “sucking air,” indicating combustion gases entering the cooling system and/or a compromised block-to-head seal. This failure sequence — persistent overheating, multiple failed repair attempts across two Toyota dealers, replacement of water pump, thermostat, and coolant bypass valve without resolution, and dealer conclusion pointing to a cracked engine block — matches the failure mode described in the federal safety agency Rec INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)

Forward facing radar system malfunction. If vehicle is parked in the sun and windshield is hot the forward facing radar is overheated and when you start the vehicle the safety system fail to boot up. If this isn't enough of a safety concern the error messages obstruct your instrument cluster screen so you can not see important things like your speedometer. You can cancel the warning but with in a few seconds it reappears and obstructs your view. Vehicle was taken to dealership. There are no recalls or safety bulletins on it from toyota corp and no known fix. This problem did not exist until toyota moved forward radar from grill area and placed it inside windshield top center. If I manually cool the area with cold water or prolonged fan blowing on the area I can restart and safety system boots up fine. This continually happens over several years, and yet still no recall. Several discussions on toyota's forum about this exact issue. Yet neither toyota or the federal safety agency are addressing it. Lets recall and fix this before someone dies as a result of the safety system malfunction or the warning message obstructing the instrument cluster.

engine coolant bypass valve 'a' control circuit/open: circuit short to battery or open I honestly feel like this is not safe. If you’re driving your engine could possibly overheat or it can crack the engine block and several different others I’m not a familiar mechanic this code just popped up My car is running a bit funny I would say that’s what made me do the scan in the first place Nobody has looked at it. I used a code scanner. I cleared the code and then I re-scanned it, and it was still there. Just for a future note, this is for a 2020 Toyota Corolla at 141,000 miles I have seen where the Toyota Corolla is having the same issue several different people at that so I do think they need to have a open investigation about this issue because it is an outgoing issue

If vehicle is parked in sun the front facing camera and laser located at the top of the windshield overheat then when the vehicle is started the overheated front facing camera is offline so the collision, lane depart/assist and auto dimming system will not boot so those safety features are offline and your screen with your instrument cluster is obstructed by warning messages. If you park in the shade or cool the top of your windshield with water prior to starting the processes boot normally and your safety systems are available. Problem is reoccurring if vehicle is parked in the sun.
