general problems of the 2010 Lexus IS

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.

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.

The coolant valley plate seal on many 2008-2014 Lexus Is f models fail prematurely causing loss of coolant and cause damage. I was changing the oil on my 2010 Is f when I noticed the pink coolant all over my transmission and I have to top my coolant off weekly so I don't damage my vehicle. Lexus has many cases of this documented but wont say that its an Issue.
