Lexus IS F Engine problems by year

I've only owned this car maybe 4-5 years and I've had to replace many parts including the alternator. Recently I stopped at Advance Auto and the technician hooked my car up and said the voltage to the battery was pushing over 1000 and shouldn't be no more than 650. Battery replaced and still having problems. Could it be electrical? The catalytic converters are also reading codes and so are the 02 sensors etc. I've replaced them and the car still isn't functioning correctly. I'm not sure what more to do. I've had technicians use scanners etc and at this point I see recalls for other years but not my 2008 Lexus Is 250.

Vehicle: 2008 Lexus IS350 Issue: Excessive oil consumption and fuel/exhaust odor I am experiencing what I believe is excessive oil consumption with my 2008 Lexus IS350. I've had to regularly add oil between scheduled oil changes, and I've noticed that the oil level is frequently low with no external leaks visible. I'm concerned that this may indicate a known issue with piston rings or internal engine components. In addition to the oil issue, I have recently started smelling strong gas or exhaust fumes while the...

From time to time as im driving to either speed up or slow down, my car has no power and then within 2-3 seconds it hits hard back into gear. I researched it on line about other lexus and it stated that the problem is in the computer and it has a glitches in the system that needs to be reset/cleared , there are times when it hits so hard that it feels like you have been rear-ended and hurts your back and neck . This is very dangerous and should be fixed by lexus at lexus expense, thank you

I was driving approx. 60 entering on ramp of freeway when car suddenly loses power to accelerator not entire car, i almost was hit by other drivers i couldnt accelerate or anything. I panicked then started pumping accelerator then it finally catches and sped up. I immediately got off freeway. Then next day CEL, Check VSC light and skid light all came on. This car is very dangerous. WHATCAN I DO??? I refuse to use the freeway until this problem is resolved.

While driving home in the freeway, I felt my car shake then a sudden loss of power. Then my CEL started blinking and my VSC lit. Got a code for engine misfire(P0302). Is250 has a lot of cases on engine misfires because of excessive carbon build up because of how the engine is designed. My car only has 108,000miles. Lexus released a Customer Support Program for this problem but it already expired. They only gave 9 years from date of purchase for it to be eligible for the free fix. It means they are aware of the...

Upon starting vehicle, engine loudly rattles for aprox. One second as if something is loose. This instance is directly in line with lexus tsb "l-sb-0155-08" (engine - brief engine knock/rattle on cold start up). Further investigation shows this is a major concern as this involves a faulty camshaft assembly.

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...

This vehicle has an oil consumption problem the same as other toyota vehicles in the class action lawsuit relating to owners having to constantly spend money on oil due to a defect in the engine. This toyota/lexus engine defect consumes oil and this problem grows worst as the vehicles get older. Toyota knew of this issue but did not inform customers, and will not help in the repair or do a recall. This problem can cause the engine to fail and cause a host of other issues.

The car has extremely high oil consumption. The cylinder walls have apparently prematurely worn down despite timely oil changes and maintenance. I am having to put 2 quarts of oil for every 1,000 miles at this point.

I went to start my vehicle and it started turning but never started. After a few tries it started and then completely went out every time. I haven't been able to use my vehicle for almost a month now. I got 3 different mechanics to look at it and they still weren't able to get it back working and I all they could tell me was it had something to do with the fuel pump and the high pressure pump.

2008 Lexus is 250 exhibits a brief rattle noise (approximately 1-3 seconds) at start-up. The issue was diagnosed by a lexus dealership which recommended replacing the cam gear assembly associated with the variable valve timing (vvt) system. The vvt gear housing and sprocket could separate and result in the engine stopping while the vehicle is being driven, increasing the risk of a crash. The same symptoms, diagnosis, and recommended repair were subject of the toyota safety recall 13v-395. The recall excluded the...

Car shakes when stopped, hesitation when pressing gas pedal

Ever since I had this car, I always had the constant problem of a weird engine smell of rotten eggs, it overheats out of nowhere constantly after multiple repairs and maintenance paid out of pocket. It would shut off while driving anywhere. These are just some of the receipts. *Tr

Constant engine repairs out of pocket within a short period of time. I have more receipts other than the ones shown
