A whistling noise coming from the transmission I took the car in and the dealer told me the it was the trans. So they change the trans. With a new and the same thing the dealer told me the Toyota knows about the problem my car has been in the shop five times for this problem and still to this day no fix for it. The whistling sound starts in any gear and is very loud and this is a (new car). This is a 2014 Toyota Corolla sounding like this. I'm afraid that the trans. May stop pulling while I'm driving in traffic which could cause and accident.

I was driving my Corolla S plus 2014 on el camino real, san mateo, ca southbound just past hillsdale blvd, when the engine became very noisy. I looked at the instrument panel and found the followings data: 1) RPM meter - 3500 2) speedometer - 30mph 3) lcd display - eco bar gone the car behaved the same even when I took my foot completely off the accelerator pedal. Transmission defect and/or computer malfunction? luckily I was able to pull my car to the roadside and braked to a stop. I turned the engine off. After 2-3 minutes, I started the engine and all returned to normal. The exact same happening occurred to me just 2 days later on March 19, 2014. It could be very scary if the engine suddenly revs up and the car speeds up at the same time. I wonder if other owners of 2014 Corolla have similar experiences. If so, this is something that has to be investigated.

After being driven for less than 200 miles of being received from dealership for a defective cvt transmission replacement, difficulties to keep the car going straight suddenly appeared, trying to do so caused it to pull the opposite during a Suburban trip in a high speed way, so had to be driven to a safer place, (getting worse rapidly), and making clunking metallic noises on the front end when turning at corners and braking, and a loud humming noise when braking from highway speed (appeared at the same time and as sudden as the steering situation) to a full stop or from highway speed to a sudden lower one due to congestion. All this happened to appear on this last trip. Had to be towed back to the dealership. Condition showed up during a continuous rainy condition, perceived like a total loss of front end alignment, plus the noises. As of the writing of this message, just a few hours have passed after the incident happened, but because of the potentially dangerous "collision situation " experienced, due the speed of the highway in which this condition suddenly appeared (nothing warned about something wrong going before) is this report being sent. Maybe caused by or related to the procedure executed during the previous cvt transmission replacement, (my opinion) has not yet been diagnosed by the dealership.

Cvt transmission making erratic ratio corrections when car was being driven at low speed which made the car literally jump at some speeds (0-30 mph) making it difficult to drive for in ex. A traffic jam (stop and go) and loose power when climbing for in ex. Parking places that had ramps (0-5 mph) due to erratic upshift ratio corrections that forces pressing the accelerator pedal to be able to keep the car climbing the ramps causing erratic jumps/speeds/pulls and sometimes the engine to backfire when climbing. Car also had noticeable jumps when braking to a full stop condition from any speed. Tested by dealership, diagnosed and replaced the cvt transmission with a remanufactured unit, got it back after 4 days. Right after driving it out of the dealer who supposedly took care of the 5K miles maintenance as well, maintenance required soon indicator started to light every time the car is started. This condition could increase the chance of an accident when driven under those circumstances due to erratic/unexpected speed variations. Trac off & check engine light came on barely for a day even though the malfunction was present and were off when the car was left for the repair in the dealer, even though the condition started at least 10 days before as an intermittent situation, getting worse at days, not present during normal to hard acceleration but had to be taken to the dealership before the appointment due to worsening of the drivability, but the gauges never lighted up, but for a while, the day before it was taken to the dealer, which may indicate that due to the nature of the problem the on boad diagnostics systems may not alert a driver of the malfunction, even though is present, which may be causing those cars being driven by unexperienced owners/drivers with that fault being present increasing chances of having a accident, fortunately at low speeds.
