| Description of the problem | 1. Even to go on a small uphill slope, the vehicle(v6) really struggles. And when i try to accelerate, it kind of stalls or slows down for a moment, then tries to speed up but its still very slow. I'm facing this issue every day. My other car 2011 camry(v4) is very smooth at the exact same places. Cant believe the pickup is this poor with a new car. 2. On highways, just to maintain the speed over 65 mph on a recent trip, i had to press real hard on gas the whole time, even after that, i can clearly tell the vehicle was working extra hard just to be over 65. This issue is consistent every time i go on highways. Many owners have reported the above issues at toyota owners forum: https://www. Toyota. Com/owners/community/ask-an-owner/question-details/id/62777282 both issue#1 and 2 might lead to/trigger a back end collision because the cars coming from behind wont know that the vehicle will slow down (due to poor pickup) all on a sudden on even a smaller slope. Same with highways too and got tailgated on many occassions on highways. Recently did the diagonostics at the dealerhsip recently but they said everything looks good. |
