My 2023 Lexus RX350 with 67,000 miles displayed a check engine light along with a Drive-Start Control Malfunction warning. The vehicle was brought to a Lexus dealership where it was diagnosed with fault code P25B372 — Turbocharger Wastegate A Actuator Stuck Open. The dealership confirmed the wastegate actuator has failed and requires replacement. The part is currently on backorder with over 800 units backordered nationally, indicating this is a systemic issue affecting multiple vehicles. Toyota has issued Technical Service Bulletin T-SB-0084-23 covering this exact fault code on the same 2.4L turbocharged engine used in the 2023 Lexus RX350. The bulletin states the repair is covered under the Federal Emission Warranty for 96 months or 80,000 miles. However, the Lexus dealership has declined warranty coverage citing the absence of a Lexus-specific bulletin, despite the identical engine and fault code. The failure puts safety at risk as the Drive-Start Control Malfunction warning indicates loss of traction and stability control systems. The problem has been confirmed by the Lexus dealership. Warning lamps appeared on the dashboard prior to the visit. The vehicle is available for inspection upon request.

While driving the engine stalls. It has jolted back-and-forth at times and had to be taken to a dealer. It’s still stalls when trying to slowly accelerate especially uphills. Low gas mileage barely getting 18 miles per gallon. Warning lights flickering while car stallling. It’s like it’s having a seizure. This has happened a few times.

I am experiencing ongoing issues with my 2023 Lexus RX500h related to the powertrain/transmission. The vehicle has exhibited abnormal shifting behavior, including hesitation, jerking, and inconsistent acceleration. At times, the vehicle does not respond smoothly when accelerating, which raises safety concerns, especially when merging into traffic or driving at highway speeds. The issue occurs intermittently and has persisted despite multiple attempts to diagnose or address the problem. The condition affects the drivability and reliability of the vehicle and has not been resolved.

2024 Lexus RX — LANE DEPARTURE

When in cruise, the car will merge itself into the next lane if you hold the turn signal partially. If you keep holding it or fully engage the turn signal (maybe you forgot to turn off you signal, or held it too long), the car will merge through the solid white line off the road into a ditch. This h...

When in cruise, the car will merge itself into the next lane if you hold the turn signal partially. If you keep holding it or fully engage the turn signal (maybe you forgot to turn off you signal, or held it too long), the car will merge through the solid white line off the road into a ditch. This happened to me once, and I noticed it trying several other times.
