2018 Lexus IS300Acceleration & cruise controlEngine & coolingFuel system

When I accelerate from a stop or while moving on a roadway, the engine seems to stall. I'm not talking about the normal turbo spooling stall. It lasts for about 3 to 5 full seconds. When you need power to prevent an accident, you can't afford that time lag, as it could cause your death. The dealer told me that lexus says it's normal, they all do it. I don't feel any manufacturer would deliberately build and sell a vehicle that would put the occupants in danger of possible death. The dealer picked up the car and...

I have only driven it about 188 miles since buying it almost 1 month ago. I called the dealer about my concern after having the car only 20 days.

running rough. I said no it just quit. This question should have been ask by the toyota dealer that did the first repair. Community toyota, baytown texas. I made a good faith effort to get the dealer and toyota co. To acknowledge they made a mistake and take corrective action so they will not do unsafe work in the future. I believe in the interest of public safety some one should see that the mechanic and service manager were properly trained. So they do not make the same mistake in the future and put drivers their passengers and other vehicles at risk. I sent certified letters to dealer and toyota co. Dealer did not respond toyota co. Said they did not get involved with service complaints. Properly training and supervising mechanics has to be somebody's responsibility. Please advise me if you can help.

2004 Lexus IS300Engine & cooling

The lexus is300 have the worst dash, I don't understand why lexus didn't have a recall on them as they did for the is250 or the is350. God forbids you park your car at work and at the end of the day when you get in your vehicle and you touch the dash or around the shifter, it feels like it is melting. And sometimes I wonder if there is some type of fume radiating from the dash itself. #2. The throttle body issue-apparently I am not the only one who is having the issue, sometimes it takes off, sometimes it doesn't push air through and there is a 2-3 seconds delay which can cause an accident especially if you are crossing an intersection. I almost got hit twice

is 300 cd changer mechanism but I wasn't notified. I took my car to westside lexus regarding an ongoing dashboard melting situation and cd player issue. Lexus finally agreed to replaced dashboard after 3 years and I am grateful but the cd changer jams now. If I haven't done my research I wouldn't know there was initial complaints regarding the cd changer. Over the month-to-month weird cd sound of tumbling then playing it progressively gotten worse. My 5- disc cd player will not play cds at all and sound is cd tumbling around in the player. Westside lexus stated I needed to replace the cd player at $500.00 And I should not have the issue at all. I should have been notified as soon as the issue was addressed. I shouldn't have to pay $500.00 For a 2003 issue. *Tr
