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.

Latest IS250/350 engine complaints
Hello: I own a 2007 Lexus IS250. My vehicle has had an ongoing engine misfire issue and has run extremely rough. In addition, my SRS light and there is an issue with the driver's side knee air bag inflator connector. Finally, my dashboard, front and rear door panels have been sticky and melted over time when it is hot and there is no reason why this is occurring. The dashboard and door panels become glossy, crack and have broken off into pieces and the shine/gloss from the dashboard causes blinding while driving...

due to the reflection of the sun on the dashboard. These issues have been going on for a period of over 10 years and I had multiple accidents due to these numerous issues. I have reported these to Lexus corporate on multiple occasions, including in 2016 and 2017. However, Lexus has refused to fix them stating that they are aware of these issues and had the ZLJ, ZLD and ZLA warranty programs but that they had expired in 2017. However, I later found out that none of those programs had expired at the time I called Lexus's corporate office. One of their programs, the ZLD warranty program, was apparently extended until 2021, however, Lexus failed to inform most vehicle owners of this. These issues are a safety issue. They have caused my car to malfunction for over 10 years and to have accidents. Many Lexus owners have also reported about these issues in Lexus owner forums on the internet and have stated that they have had accidents due to these issues, but Lexus failed to properly inform customers of the extended warranty and refused to fix these cars. With these issues continuing and becoming worse over the years, they are no longer a warranty issue, but a safety issue for drivers. I am requesting that the NHSTA investigate this issue and require, if possible, that Lexus issue safety recalls for these known defects and fix these issues immediately to prevent car accidents.
Engine is consuming too much oil regularly. I have to fill in a quart every 600 miles or so. Interior panels are melting
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...

engine is running, especially at idle or when the car is warm. I am worried that this may be related to catalytic converter damage caused by prolonged oil burning. I believe this may pose both a safety risk and an environmental concern, especially if the catalytic converter is compromised. I have not yet received any recall notices or service bulletins related to this issue, but I am aware that similar Toyota and Lexus models have had oil consumption problems tied to engine design.
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
The vehicle is burning engine oil at an increasingly severe rate, with the manual stating that burning 1.1 quarts every 600 miles is normal. This consumption is excessive given the 5.5-quart capacity and the requirement for expensive full synthetic oil, causing frequent and costly top-offs. This poses a safety risk due to the potential for engine damage or failure if oil levels are not closely monitored. Some owners have had the issue inspected, and Lexus has acknowledged the problem. However, they have stated that...

repairs require replacing components costing multiple thousands of dollars just for parts, leaving many owners without a feasible solution. This problem is widespread, with numerous reports of similar issues in online forums ( [[redacted]] ]). A thorough investigation and a more customer-friendly resolution are needed to address this design flaw and ensure reliability and safety.

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.
This is happening on the lexus is250 as while as the 350 the loose bolts could cause the VVT gear housing and sprocket to separate and result in the engine stopping while the vehicle is being driven, increasing the risk of a crash. Toyota is recalling certain model year 2007-2011 Lexus GS350 vehicles manufactured June 19, 2006, through July 12, 2011; and model year 2006-2011 Lexus IS350 vehicles manufactured May 27, 2005, through July 13, 2011; and model year 2010-2011 Lexus IS350c vehicles manufactured November...

25, 2009, through July 19, 2011. These vehicles, equipped with the 2GR-FSE engine, use bolts to secure the housing and sprocket of the Variable-Valve Timing (VVT) system gear assembly. These bolts could become loose due to abnormal impacts generated within the gear assembly immediately after a cold start-up.
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...

problem but my 2010 car just missed that window but I am having the same problem many IS250 owners have. It is really unsafe when you're driving in the freeway then it suddenly loses power. Hopefully this problem gets resolved by Lexus soon.
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.
Power steering keeps going out and steering wheel making grinding noise. Almost crashed when lost steering on freeway. Car also makes noise while starting cold
While driving there was no warning lamps messages or other symptoms to any problems. I went to slow down so I could turn around because I missed my stop. The brakes started feeling less pressure I looked up and there was black smoke coming from under the hood then I saw flames. Then the car blew up
Camshaft problem. Loud rattle at start up bad ticking. Transmission fluid needs to be changed and serviced at a schedule time. Bad performance all together with only 119,000 miles. I have now rebuilt the motor paying $3000 to fix the cams and now have to repair the transmission
The car is consumed alot of oil. I've been using 5w30 motor oil. 2/6/2022 had my oil changed, 2/8/2022 oil light came on saying low oil level.
