2011 Toyota Camry - noticed acceleration during slow braking

[krisgg]

Hi all, I have Toyota Camry 2011 4-dr LE. While I was on a road trip recently, the car did something very odd. The vehicle started to cut out and it then stopped. I have to note that it was at a high altitude (somewhere in the Colorado Mountains). After the incident I was able to start up again and the vehicle operated as expected. This is not the problem I wanted to ask about, however I thought I would mention it in case you think it might be related.
Here is the problem I have: When coming to a slow stop or driving in the slow traffic, sometimes the vehicle seems to accelerate when the break is released, as if I have pressed the gas pedal. I would expect that once slowed down the Camry will maintain its speed. Other times while my foot is still on the brake pedal (lightly pressing it during a slow down) I would feel as if I have released the brake for a second and the car accelerates (at which time my reflexes kick in and I press the pedal harder). In addition, the transmission seems to hesitate on up shift. I have noticed multiple times that the transmission does not shift on-time and I could feel it when I drive slower.
So here is my question: Does any 2011 Camry owner has had similar issues/problems with their vehicle, or does anyone that works for a Toyota dealer has had similar complaints from other customers? Could the problem with acceleration during braking be also related to transmission down/up shift problems?
Since the problem with brake malfunctioning and engine acceleration is very infrequent, when I took the car to the dealer they could not find anything wrong. Before I take any other steps in resolving the issue I would like to take this issue to the community at large to hear some feedback. Any general comments on the 2011 Camry transmission quality/functioning will also be appreciated. Thank you very much for your help.

I never noticed any acceleration or trans issue like some have posted in the '11 LE but do feel the car seems to roll(coast) faster downhill.
No big deal,though.

I have not noticed this issue you mention. However, i too agree that it seems to coast must faster downhill. However if you take it off Auto and put in the the "manual" mode and lower the gear that is supposed to slow you down without using the brake.

It might accelerate briefly if it downshifts.

[tengiday]

It may be a jerk when downshift, making you to feel as if the car accelerates a bit. Anyway, how long have you been driving your car? Break-in or not?

[njerald]

It's not the car.....

The car is downshifting which would cause a jump in rpm and a slight acceleration feeling.

[islandboy57]

Are you sure it's not the A/C compressor kicking in? It bumps the RPMs up a little to compensate for the additional load and it's more pronounced with the 4-cylinder for sure.

I have had the same observation when driving my 2011 camry xle v6. I notice when I am slowing it does a little acceleration. Also when accelerating the transmission stalls when shifting gears almost like it needs and oil change, the car dips back and then plunges forward like I am pedal to the metal but I am not. I thought it was just me, guess not.

Ive noticed these cars do coast alot farther. Thats really good for fuel economy since you can use it your advantage when approaching lights. When i first purchased my 2007 I noticed the car would not down shift when trying to pass cars. It was really dangerous but i took it in for a TSB and problem solved.

I have had the car since June 30th and I have put on 4.7k miles on it. I noticed the issue since day one but I thoguht it was me. After a while though I started to realize that the issue was consistent.

Here is a quote from a reply from antoher thread I started. I guess it's not just me:

It's very interesting running into your posting. I am from Minnesota, and had a very similar experience. My camry was one week old with less than 400 miles on it. I was coming to a stop sign at slow speed. I was about 10th away from stopping when the car noticeably shifted down and at the same time shot me forward about 2 car lengths into the intersection. My head flew back and hit the headrest. I was injured. I took the car to the dealer they found no problems. A representative from Toyota out of Chicago came and also found no problems. I asked if they would like to take the car home and put their family in it and of course no one will. I included my email feel free to contact.

Any others with similar experiences on the 2011 Camry?

Negative. 5,200 miles on mine and it's been problem-free.

[Pete Toyota]

No problem with my 2011 either.
