| I have a 2006 lexus is250. i noticed rough starts and idle. this was at or around 65k miles. i assumed it was related to super cold weather or bad gas (after the car sat unused for 2-3 days+) at around 84k miles during warm weather - i experienced both a rough start and stalling at a stop sign. i took the vehicle into my local dealership where it has been meticulously maintained. they did an extended diagnostic (kept the car over a long weekend) and advised my car was not firing 65-85% of the time and that it was caused by the valve springs. this is a $5,000 repair. lexus claimed because the issue was outside the 70k mike warranty they would pay for the parts of roughly $4,000 as goodwill but i would be responsible for the labor at $945. i did a search for recalls and learned that the exact issue is under recall for other models inclusive of the is350 v6 - which the company regularly refers to as my car's sibling and has shared previous recalls with. i've contacted lexus directly and they have advised the offer is final. they have refused my request to speak with the manufacturing rep. i believe this stall issue is a significant safety concern (per the recall noted) i've asked lexus whether or not they have researched this issue on the v6 250 for which i've not received a response. i believe that lexus would have used the exact same manufacturer for these value springs and or very similar design specifications. it is incomprehensible that given this specific diagnosis they would not resolve this immediately. i believe absent a nhtsa investigation lexus will continue to hold customers hostage to pay for their safety although every indication is that this is a design/manufacturing defect for this model as well. | |||

| I own a 2006 lexus is250 and there is a problem that i cannot see to handle nor the dealer can handle. the problem with the car is that when i'm going over 60 to 65 mph the check engine light blinks and the vsc light comes on. the car does not accelerate and just the rpm would go up. i took the car in to the dealer with extended warranty in hand on 4 now 5 different occasions and everytime i'm hearing different stories. here is the list. * may 22, 2009: 60,000 mile service done. * sept 6, 2009: took the car in for check vsc & check engine. next day they told me nothing was wrong with the car. * oct 10, 2009: towed car to dealership. check vsc & check engine light came on again. pulled over on the highway 3 times to reset but the lights did not go away. pulled over twice earlier that day, twice the day before also. * oct 14, 2009: (lexus told you that the issues were resolved by swapping the engine coils the day or two before. no charges.) i requested an emissions test before i came to pick it up. lexus called back and told me that the engine light came back on again during the emissions test. still looking for the problem. * oct 18, 2009: lexus called, told me that the problem with the engine is because of the carbon buildup. they were going to cover the valve springs but i would have to pay for the cleanup which is $ 960. not covered by ext. warranty. 2 other dealers told me that the carbon buildup cleanup was an injunction service and it is supposed to only cost 190 dollars. the funny thing is that the dealer wrote the problem is caused by carbon buildup cleanup? with a question mark. took the car and had the injunction service done. i took the car to another lexus dealer and they told me that while the other dealer was doing the coil swap they cracked the cover for it and now gas was leaking. had to get it fixed and also did the carbon buildup cleanup (injunction service). feb 2010 same problem occurred. *tr | |||

| Car started to run rough, slowed down, check engine light and sbs light came on (ithought it was an oxygen sensor). book says to take to dealer immediately. i took it in, they did a check, told me it was a 'loose gas cap'. a month later - same thing happened. i took it back, they kept the car for two weeks - told me the valve springs were not the correct length and had to be replaced. *tr | |||

| I was operating my 2006 lexus is250 awd at very low speed in a parking lot when the engine began to surge. i could not bring the car to a stop using the brake pedal and could barely keep it from creeping forward. i shifted into neutral and the engine really began to roar, revving very high, but i was then able to stop the car and turn it off using the stop/start button. when i restarted the car it operated normally and the problem did not re-occur. the floor mat had nothing to do with the problem, as it was a factory mat held in place by the little hooks, and was not the all weather mat. the mat was in place after the incident. i reported the occurrence to my dealer, warnock lexus, in livingston, n.j. they checked the car out and found nothing wrong and no evidence of anything wrong in the computer's memory. the problem did not recur and the car was returned to lexus at the end of the lease. i now have a 2009 is250 awd and am concerned about the reports of this problem. i don't feel the floor mat had anything to do with it. the date below is approximate, but lexus should have a record of the incident from the dealer service department. *tr | |||

| I purchased a 2006 is 250 in october, 2005. the vehicle has been driven for 2,500 miles. after the engine warms up, smoke and a burned smell come from the engine compartment. the first time i brought the problem to the dealers attention i was told that everything was normal. i brought the vehicle in a second time and it was discovered that oil was leaking from the passenger's side valve cover onto the hot exhaust manifold causing the oil to smoke and burn. the vehicle is now at the dealers service department and i am being told that they do not know how to fix the problem and that they have no parts to use for replacement since the design is so new. the problem is related to the high oil pressure maintained by the engine according to the dealer. the engine is covered with plastic panels and i have advised the dealer that continual leakage of oil onto the hot exhaust manifold with a plastic cover on top of the engine could result in an engine fire. smoke is visible from the engine compartment when the engine is running. *jb | |||
