At a steady speed, steady rpm between 2000 and 3000, on flat surface the rpm suddenly drops 200 to 500 rpm then jumps back up to cruise.
Does this every fifteen seconds or so almost all the time.
Dealer service says "Oh yeah, that's what Corollas do"
"There's no fix"
It's VERY annoying.
May have something to do with Downhill Braking assist of the electronic transmission.
Many other owners have reported exact same thing and Toyota doesn't appear to be doing anything about it.
I would avoid Corrollas until they fix this.
I looked over many cars and narrowed 'em down to the Ford Focus and Toyota Corolla. The 2012 Focus is all new styling for body and auto transmission. The front of this Focus looks cheesy and isn't functional, being nothing more than mostly a bug catcher. A new, double clutch auto transmission, worried me also - no track record regarding functionality and durability. The Focus gas cover was cheap plastic with matching body paint.
The Corolla I chose was an S model. I've owned for 1 month. This had the 16" wheels I liked. The steering is TOO responsive, but i'm used to it now. Terrific gas mileage at 31mpg driving 75-80mph. Comfortable. Too much static creating vinyl and plastic inside tho.
2011 Corolla S w/o sunroof
Purchased new: $17,500 exclude TTL. (Sticker: $20,120)
This is a very smooth riding car for this class and seems very solidly built. This car rides like a Camry on smooth roads but the short wheel base gets a bit unsettled over uneven pavement and it crashes over rough patches and potholes somewhat.
The powertrain also runs very smoothly and acceleration is adequate. All in all the best value in the class.
I have tested and driving and owned Honda Accords (nice car but the year I had it, they engine light for low oil didnt come on until you were already out.. hence the car burned out.. nice..) and I have owned Civics and felt like I was driving a speedy but bumpy car, and the recent Mazda 3 with the larger 2+ engine, and BOY did that have nice power and luxury items.. and I just bought a Corolla.
You know why?
None of those other cars, though sporty and full of styling ideas, and lots of toys, drive as nice or as quietly.
And it has great safety features.
That seems to be discounted too quickly for flash and speed and I got really tired of the bumpy drives of my Civic and especially my M3.
I looked at every car out there and to me the Corolla was the best for what I needed.
Toyota is known for resale and engines that go forever.
I put over 250k on my Avalon and its still going strong.
The mazda's were to loud and will not last, the honda's were to much money and I will not buy a hyuandi because they are simply not on the same level in quality regardless of what they say.
Kia Forte was sharp looking but drove and rode the worst of the group.
The corolla is the best selling car in the world for a reason.
