#1 of 19 Lexus ES350 Transmission Issues by rosstek Jul 02, 2007 (8:06 am)
I've had my car approximately one year now and drive it regularly. It has about $26K miles, but just recently ( two months) I've noticed some performance issues. Regardless if it was in the morning and the engine was a little cold or in the middle of day, the acceleration would slip. It was difficult to replicate the issue, but it was consistent enough to notice. On several occasions, I would redline or come very close to redline. It was as if the car was in neutral, but then immediately adjust. I took the car back to Lexus twice, but they were unable to identify the problem. Finally, just last week it happened again and Lexus finally decided to replace the transmission. They said they were unable to identify the problem, but would replace it anyway. In lieu of my problems, I was given $1000 in service credits. Overall, I really like my car, but now I'm somewhat skeptical that I might have more issues down the road. I am leasing, so I guess that helps in some degree. Thought I'd share this information.   Fred Replies to this message: ycu (Dec 13, 2007 10:14 am)
#2 of 19 2007 lexus 350 axcelator problem by wrh2 Jul 20, 2007 (6:33 pm)
i own a new es350 with about 10,000 miles. at 3000 miles they put a new transmission in my car due to a shift malfunction. my most recent issue was when the car exclareted from about 80mpg to 140mpg. i braken continuesoly for about 10 min while shifting into neutral. i was fortunate not to be killed or kill another. the car slowed to about 60mph and i coasted. the end result is the i recently had knee surgery to repair torn mincus due to the pressure put on my knee from brakeing.   Has anyone else hada this problem.   royhaassbcglobal.net Replies to this message: wrh2 (Jul 20, 2007 6:41 pm) jaspalb (Jul 20, 2007 7:24 pm) warty (Oct 04, 2008 8:57 pm)

Replying to: wrh2 (Jul 20, 2007 6:33 pm) has anyone had an issue with the axcelator locking up? I recently had my car axcelarate from 80mpg to 140 mpg while traveling on the interstate. I braked continuesly for over 10 min. The brakes burned up and I required surgery to repair my knee from the continuous pressure. Has any one else experienced this problem?   royhaassbcglobal.net Replies to this message: jaspalb (Jul 20, 2007 7:24 pm) warty (Oct 04, 2008 8:57 pm)

Replying to: wrh2 (Jul 20, 2007 6:41 pm) Did your accelerator pedal get stuck under the All Weather rubber mat? It can happen if it is not properly held by clips?
#5 of 19 Transmission Issues? by praz Nov 13, 2007 (3:23 pm)
I always wonder what the transmission issues are with ES350. It is my second car and first luxury car that I have ever purchased. I had rattle issue which is fixed now. But, can anyone please enlighten me on the issues regarding transmission and what I should look for to check if my car has issues? Thanks in advance.

Did you mean 30% of owners or 30% of people on the ClubLexus forum? That could be a huge difference.

My ES 350 with 10000 miles is shaking the car between 30 and 50 miles per hour. It sounds like I am going over some small speed bumps . I have balance he tires so that is not the problem. Please help as the dealer is not . Anybody else having problems with the transmission, Also my dash has all kinds of rattles in it. Is this common as this is my first Lexus.

Replying to: rosstek (Jul 02, 2007 8:06 am) That trans problem that you have > it's not a probem !   Its just happens when your trans changes major gears as it changes energy output. Most often it occurs when you apply sudden move from over 2500 rpm to 3,000 rpm, and then right away, the rpm suddently move down by a few hundred clicks - this is the slip you described. There is another one between 5,000 to 6,000 rpm. You see this has to happen because the large horsepower (272 hp) and the way the trans is designed. I have them on mine and its completely natural ! It happens everytime when I apply really fast Accell increase from 2500 rpm to 3000 rpm. Also, after this slip, the engine sound changes from a desel to a race car like sound. These things that you experience is all due to major Torque, Horsepower changes with respect to changes to gearshift. Oh ya, it happens again at the upper rpm near the redline and another one somewhere between 5,000 and 6,000 rpm.   The one at redline is due to high fuel input as hp decrease after hp max. at 6,200 rpm. Don't do this to your car - its damanging for your engine because when hp decreases over 6,200 rpm alot of energy is transfered to the engine and not released to the environment as hp and torque. When you have large energy transfer to engine > engine wears.   Also, Lexus agreed to give you a trans changes just to satisfy you b/c they can't have a bunch of unsatisfied buyers or sales will decrease dramatically.
