Lexus IS250 Engine problems by year

Valley Plate Leak. The Valley Plate Leaks are notorious on this vehicle. There have been several forums about it.

While stopped at a stop light vehicle RPM went very high. It reached the red zone. Vehicle started moving forward (while still on Drive and the brake pedal fully pressed). I immediately put the vehicle in Park. RPM continued to remain high. I removed my foot off the brake when the vehicle was in park. I turned the engine off, waited couple of seconds and turned it back on. At that point everything worked normally. Outside temperature was about 38 deg F. Car was not fully warmed up at the time. Floor mat had...

Tl* the contact owns a 2014 lexus is250. The contact stated that while driving at an undisclosed speed, the vehicle stalled with the check engine warning light illuminated. The vehicle was taken to an independent mechanic and was diagnosed that the fuel pump failed and needed to be replaced. The vehicle was not repaired and was not taken to a dealer for a diagnostic testing. The manufacturer was not made aware of the failure. The failure mileage was approximately 69,000.

Valley plate leak due to the fact that toyota/lexus utilized the improper sealant and used the improper amount, leading to the heat exchanger leaking coolant once the original, inadequate sealant begins to disentegrate. This could cause a condition where the engine could fail and someone could get hurt. Furthermore, all isfs will eventually have a cracked rh manifold on the #8 runner. This can cause a fire hazard in addition to carbon monoxide poisoning.

Fuel is not delivered to firing chamber due to failure of fuel pressure sensor. This will cause engine to shut off when on the road. No obd-ii code is present since the failure of the fuel pressure sensor will put the car in protected mode, no code can be read. When engine is shut off, it will have no power to steering or brake system, put driver in a very dangerous situation. I was lucky enough to find out after arriving home. The problem appeared the next morning.

Takatabrantakata recall my vehicle was rear ended at 34 to 50 miles an hour. The vehicle behind me impacted me so hard that it pushed me into the vehicle in front of me and in turn she hit the vehicle in front of her. There was damaged to the front and side panels of my car as well. The air bags failed to deploy. I sustained and suffered injuries. This occurred on a busy city street while at a traffic light.

Unintended acceleration while inching into parking space at very slow rate of speed. Engine raced unexpectedly and car jumped curb with all 4 tires, across a small median, and down another curb with 3 tires, striking a parked car, which stopped forward motion.

The engine could stall in the middle of driving because of misfire. My lexus 250 only 40k mileage and always do proper maintenance to the engine every 3000 mile. I do research that lexus is 250 cause carbon build up because of the wrong design of the direct injection. Here's the youtube link: https://www.Youtube.Com/watch?V=ytquqflawr8. I brought the car to lexus dealer, they won't admitted, instead they blame me using a wrong fuel. Before I used 91octane shell, then I switch to 91octane chevron. Still has the problem. They should recall for this matter, because it's about safety and the engine could suddenly stall in the middle of driving.

Engine stalls after coming to a full stop and then trying to accelerate. Car will creep out into an intersection, then will suddenly accelerate. This leaves me vulnerable to being hit by on coming traffic. Happens on city streets after coming to a complete stop. Can happen when I am going in a straight line or turning. Happens often, but not always.

Without warning, the vehicle stopped accelerating as I was driving so I pulled off the road onto the shoulder. Once the car stopped, smoke began to come through the vents so I exited the vehicle. Several minutes later I could see flames coming from under the hood. Before the fire department could make it to the scene, the entire front end of the car burned completely. The fire department said they were going to classify it as a "mechanical failure". *Tr
