Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The contact owns a 2015 Toyota Corolla. While driving at an unknown speed with the air conditioner activated, there was a strong mold odor coming from the vehicle. There were no warning indicators illuminated. The vehicle was taken to the dealer were the air conditioner charcoal filter was replaced and a chemical spray was applied to destroy the mold. After the repairs were performed in the spring, the vehicle was not driven again until the summer. While on a long road trip, the mold odor was detected again and the contact became ill. The dealer stated that nothing could be done because the vehicle was repaired according to the Toyota manufacturer's protocol. The manufacturer was notified of the issue. The failure mileage was 25,697.

Bought May 2015, warm day, firm brakes. Wet, cold fall months brakes became soft w/ excessive travel & erratic during 40mph & under. Took to dealer Sept 2015 at 1,562 miles. Tech performed road test. Couldn┐T duplicate conditions. Checked for codes. Stated ┐found normal braking conditions┐. I started driving again & noticed during warm days around 70 deg brakes changed hardness with A/C on. More firm. During colder days brakes would go within 2 inches of floor before working. Took to dealer on ┐walk-in┐ basis when car was acting up. Drove w/ tech 1 hr tried to get him to notice difference in brakes. Tech stated brakes were acting ┐normal┐ & that I just wasn┐T familiar w/ how the systems operated. I insisted it wasn┐T normal. Tech contacted manufacturer. They said replace master cylinder and bleed system. Returned car & stated ┐driving correctly now┐. I started driving again & noticed whistling sound coming from engine compt when driving under 30mph between bdlgs w/ window down. Brakes go all the way to the floor at times & they grab & the car stops abruptly. Especially in stop-&-go traffic. Took to dealer March 2016 at 4,800 miles. I suggested checking entire vacuum system for leaks. Tech only checked line to brake booster. Tech made ┐little┐ adjustment to E-brake & rear brakes. Tech stated brakes ┐feels similar to new Corolla┐ & no whistling sound. I can still hear whistling sound & brakes still have same issues! I think it's a design flaw related to the entire vacuum system & should be recalled! told dealer. Test drove 2016 Honda civic w/ similar braking systems it performed like a new car should! other issues w/this Corolla are the suspension is too ┐loose┐ when traveling above 55mph & changing lanes, the engine is way too loud when accel & often knocks during accel & idling (changed gas stations & checked fuel type, still same problem), & headlights R 2 bright...

The new Toyota Corolla's have several issues with their headlight design. First, the daytime running lamps on vehicles with the xenon or led lights appears to be the same lights that run at night when you turn on the switch. This means that people in oncoming lanes constantly flash their lights thinking the bright lights are on during the day because it is extremely bright. I've also noticed that a lot of other people with this same car don't realize they have to manually turn on their lights since the brightness of the daytime running lamps is the same as when the switch is turned on. People must think they have automatic headlights and subsequently fail to turn their light switch on which means they have no rear lights. I can see this causing so many accidents, especially in the rain or at night. It is extremely dangerous. People have also complained to me that it looks like the bright lights are on when they're not and the headlights are "blindingly bright", but how the lights are aimed or designed, they don't cast much light on the road ahead. It seems like the light is just diffused in all different directions instead of in a beam like normal headlights. There is a huge issue with these new Corolla models' lighting systems and Toyota needs to retrofit them immediately to prevent accidents. In addition, this car basically has no power which makes it next to impossible to pull out in traffic as the awful cvt transmission takes forever to respond. Once the engine has finally woken up from its sleep, it offers terrible response and is extremely slow picking up speed. This is an issue with all Corolla's because of how heavy the car is for how little power Toyota gives it. I also hate the huge blind spots created by the awkwardly shaped rear end. I'm glad this is just a rental car, but I feel so bad for owners of this type of car.

Stopped at a red light with foot on the brakes. Out of nowhere the car accelerated forward extremely fast. Forced to hit an car in front of me within a car or two, distance wise. After the incident the RPM gauge fluctuates from low to high. In addition, once gas pedal is pressed car slows down and eco activates, then after about 5 seconds car accelerator extremely fast.
