“The first thing I noticed was at least two weeks ago when I couldn't adjust the radio volume while driving, thought maybe there was a safety feature that wouldn't allow you to do so if driving. Today we hopped in the car to do a quick errand and noticed the radio had no display on it. While friend was in the store tried turning the radio off and back on again, then tried turning the car off and back on again finally tried pushing every button that was related to the radio. …”

“3 months after purchasing this vehicle, mice starting coming into the air filtration system. I have tried to keep them out however the design flaw in the cabin air intake will not prevent them from coming in. There is a huge opening where they constantly come in. I have 2 small children and this is very very dangerous between diseases and threat of wires being chewed. We also had a Toyota tundra that had this same problem. My husband traded it in and has a ford now and does not have a problem at all with mice.”

“On january 7, 2016 we brought our car to the weston, florida Toyota dealership because a check engine light was on. The service writer said there was a problem with the canister and that it had to be replaced. They gave us a loner-car and said the problem would be fixed in two days. Later that week, the service writer told us the computer had to be replaced and it would be a while until the part arrived. We still have the loaner and the car has been at the dealership since january 7th. Today is april 27th. So far 110 days. The loaner car is very nice (2015 Toyota Corolla). …”

“I drive quite a bit and normally know my vehicles pretty good. I have recently obtained this 2011 Toyota Corolla s and it is in great condition overall. I made a trip 2 days after getting the vehicle and immediately noticed a hesitation between 55-65 MPH. The first time it was approximately 11am in the morning at 78f. Driving on a flat well maintained black top road the vehicle does in fact have a constant hesitation that drops approximately 1000-2000 rpms with a noticeable feel in the vehicle. Immediately (3-4 sec) after the hesitation the vehicle recovers back to the original RPM. …”

“Around 250-300 miles I went over a dip in the road at about 40 MPH and went to hit the brakes while taking a turn that was approaching a stoplight when the brakes would not let me push them down and would give me feedback as if ABS was active. After a couple seconds I was able to reapply pressure to the brakes to stop. This happened a total of eight times in 2,100 miles. The car has been in some close calls, and all the incidents happened after hitting a dip while trying to reduce my speed from over 50 MPH to the time of hitting the dips. …”
