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.
Valley plate leak.
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.
Tl- the contact owns a 2008 Lexus Is250/350. While driving 60 mph the vehicle jerked and shut off with warning. The contact stated it would take several tries in order to restart the vehicle. The vehicle was towed to an independent mechanic. However. The vehicle was not diagnosed or repaired. The VIN was available. The manufacturer was not notified of the failure. The failure mileage was 15000. Lj.
Car shakes when stopped, hesitation when pressing gas pedal.
Constant engine repairs out of pocket within a short period of time. I have more receipts other than the ones shown.
Why Is there a recall for the Is350 vvt cam gears and not the Is250 ???.
I took my car to the local dealer for the carbon buildup recall in the motor. They rebuilt parts of the internal motor. After they rebuilt the motor for carbon build up, my engine light started to light up for bad catalytic converter. I told them that the light never showed up before and could've went bad from all of the miles of carbon build up that damaged the catalytic converter. They couldn't repair the catalytic converter because I was out of the warranty period.
Airbag recall in incomplete and engine Is knocking.
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.
When coming to a stop or when at a stop, my car would shake very hard as if it was going to turn off. Fortunately, it never has. I would have to put the car into neutral to stop the shaking or it would stop on it's own after 10-15 seconds. During this time, no lights have ever turned on to indicate there was a problem. The first time this happened was in late July 2009/ early August 2009 and ever since then, it would happen at least 2 times a day. My car has been in the shop multiple times for this Issue.
