2015 Toyota Avalon Problems

The contact owns a 2015 Toyota Avalon. The contact stated that while driving at an undisclosed speed, there was an abnormal grinding sound coming from the brakes. The contact stated that the brake warning light illuminated, and the brake independently activated. The vehicle was taken to a specialty brake shop, where it was diagnosed that the brake actuator had failed, causing the ABS system to activate independently. The vehicle was repaired. On the drive back to the residence, the failure recurred. The vehicle was taken to an independent mechanic where it was diagnosed with brake master cylinder failure. The brake booster, gasket, and brake actuator were replaced. The contact stated that two weeks later, the failure reoccurred. The vehicle was taken to the dealer where it was diagnosed and DTC: C1441 and C1431 were retrieved, indicating an issue with the ABS system lateral acceleration sensor circuit or the brake booster. The dealer became aware that the front bumper bracket had paint on the part that did not allow for the vehicle to brake correctly. The brake pedal support assembly with sensor was replaced, and the paint was removed. The vehicle was repaired. The contact related the failure to NHTSA Campaign Number: 15V728000 (FORWARD COLLISION AVOIDANCE). The manufacturer was made aware of the failure. The failure mileage was 83,829.

05/04/2025 First of all, we love our Avalon. However, for the last 6 months or so, water is getting in the car and ends up soaking the carpet on the left front floorboard carpet. We have checked everything we can think of to find the source of the leak but was uneasily. We had to have some scratches fixed and took the car to a body shop to see if they could find the source of the leak. They sprayed water on the sunroof for about an hour but no water leaked inside. We have also taken the car to the local Toyota Dealership (Sheehy Toyota in the Fredericksburg area, they could not find the source of the leak. It rained here (Fredericksburg, VA last night and the left front floorboard was soaked. I need help finding the source of the leak(s) so we can continue enjoying our Avalon. Any help would be appreciated. Thank you, [XXX] [XXX] Phone number [XXX] (cell phone) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving the pre-collision system (PCS) turns on unexpectedly, without any warning lights or sounds, and applies the brakes. This happens when I am driving in traffic with plenty of space between the car in front of me. I typically drive between 3-6 seconds behind the car in front of me to allow for at least 300 feet in space when driving at highway speeds. Despite leaving plenty of room for cars in front of me, on multiple occasions the car has started braking abruptly while going anywhere between 50, 40, 30, or 20 miles per hour. This can be verified for inspection upon request. Despite there being a recall for my specific year, make, and model car (2015 Toyota Avalon) for this exact issue my VIN number is not covered. Toyota is requiring me to pay out of pocket for them to 1) determine if its malfunctioning and 2) replace the system, which is a huge conflict of interest. Even though the Driver's Manual says that I can disable the PCS by clicking on the PCS on/off button within the driver's glovebox, there is no such button, only a blank button cover. Not having the ability to disable the PCS system, or worse, allowing it to continue braking while I'm driving is a serious hazard. The car can start braking while I am accelerating to merge onto expressway on-ramps, or while changing lanes at the same speed of traffic. The car can also unexpectedly brake while cars are traveling too close behind me. I want to know why my VIN was not included in the initial recall and why I now have to pay to have it looked at or repaired when its clearly malfunctioning and can't be turned off as the Driver's Manual says it can. I should not have to pay $175 an hour for several hours for a Toyota dealership to diagnosis it and then another $175 an hour for 2.5 hours for them to install the fix and whatever the new component costs. I recently bought this car at 35,500 miles and the issue immediately started occurring just as the warranty expired at 36,000 miles.

The body of the car, clunks when making a right or left turn while leaving the road and entering a slightly raised or lowered entry. A very clear clunk sound occcurs emanating from the overhead, just behind the driver's seat. It doesn't happen every time, but is increasing in frequency. I don't know if this is or will be a safety risk. This has not been witnessed or confirmed by Toyota and cannot be verified by inspection because it is inaccessible, behind the overhead. It first occurred and was reported around the 50,000mi servicing.

I have tire size P225 / 45 R 18. Michelin Primacy mxm4. The compalint tire exploded at 65 MPH (the speed limit). The falure caused the car to swerve into the next lane which was occupied by another car at the time. My safety was at risk when I momemtarily lost control of the vehicle and others were at risk when I enetred an occupied lane. Problem was inspected and confirmed by Mavis (formerly NTB) in Keller TX. The only warning was that a couple of weeks prior to the incident while rotating my tires the Mavis location found a bubble in the sidewall of another tire (not the one that exploded) that was in the same lot as the one that exploded. It was replaced under the warranty. I now beleive that the entire lot of tires are defective and have asked for a completely new set of tires.

Tire Size 225/45 R 18. The tire had slightly over 3,000 miles on it. 1. Rear driver side tire that is in my possession and available for inspection, but is in 2 parts. 2. My wife and I traveled from Brandon, MS to Birmingham, Al for a medical appointment early the next day. In Tuscaloosa, Al driving in right hand lane approximately 60 MPH the handling became rough, the tire blew out, causing loss of control and throwing the vehicle in center lane, fortunately no other vehicle was there, I regained control and moved to side of road without out any physical injury. 3. After attempting to change the tire, a wrecker had to be called and towed to the only tire store open, Firestone. The technician removed the tire and said the tire separated and was replaced with a new tire. 4. Upon returning home, the tire was taken to my dealer who inspected the tire, said it was too torn up (2 pieces) to tell if it was structural failure and Continental would not do anything. He said if tires fail it is in 1st 1,000 miles and something must have been hit. I advise that nothing was hit, that Continental needed to know about the tire. He offered no further assistance. 5. Tuscaloosa & Birmingham are roughly 50 miles apart, a little prior to reaching Tuscaloosa, the low tire sensor came on, which it will do occasionally, did not notice any change in how the vehicle handled and planned to have it checked out at a Continental dealer in Birmingham the next day.

ON FEB. 5, 2020 AT ABOUT 6:30 AM, MY WIFE WAS PULLING UP BEHIND CARS STOPPED AT A RED LIGHT, AS SHE APPLIED THE BRAKES TO STOP, THE CAR SUDDENLY ACCELERATED, SHE PRESSED THE BRAKES AS HARD AS SHE COULD, THE CAR CONTINUED TO DRIVE FORWARD HITTING THE CAR AHEAD OF HER IN LINE. SHE COULD HEAR THE CAR ENGINE RACING AND TRIED TO PUT THE CAR IN PARK, BUT IT WENT INTO REVERSE AND RAPIDLY MOVED BACKWARDS, EVEN WITH HER FOOT ON THE BRAKE, HIT THE CAR BEHIND HER. SHE THAN ONCE AGAIN TRIED TO UP THE CAR IN PARK, BUT PUT IT BACK IN DRIVE AND THE OUR CAR ACCELERATED FORWARD AGAIN FILL SPEED HITTING THE CAR AHEAD FOR A SECOND TIME, ALL THE TIME HOLDING HER FOOT DOWN AS HARD AS SHE COULD ON THE BRAKE. AFTER HITTING THE CAR AHEAD FOR THE SECOND TIME, SHE PUSHED THE ENGINE STOP BUTTON AND THE ENGINE STOPPED RUNNING AT FULL RPM. SHE NOTED THAT THERE THE FRONT TIRES WERE SMOKING ALOT SINCE THE TIRES WERE ROTAING EVEN THOUGH THE CAR WAS AT A STOP, DUE TO THE ENGINE RACING FULL RPM. POLICE WERE CALLED AND THEY DISPATCHED A TOW TRUCK FOR OUR CAR. THE POLICE NEVER ARRIVED, THE TOW TRUCK LOADED OUR CAR AND TOWED IT TO THE AAA STORAGE YARD .

ON MAY 25TH, 2020 I WAS PULLING INTO A TACO BELL DRIVE THROUGH. IT WAS LOCATED UP A LITTLE HILL. AS I DROVE UP THE HILL I HIT A LITTLE CURBING. I BACKED UP AND ADJUSTED THE CAR TO MISS THE CURB. WHEN I PUT THE CAR INTO DRIVE IT LURCHED FORWARD AT A HIGH SPEED. SEEING I WAS GOING TO HIT THE CAR IN FRONT, I HIT MY BRAKES. THE CAR DID NOT STOP UNTIL I HAD HIT THE CAR IN FRONT WITH A LOT OF FORCE. THAT CAR WAS THROWN INTO THE TRUCK IN FRONT OF IT. THAT WAS THE BEGINNING OF A HUGE SCARE! I PUT THE CAR IN REVERSE SO I COULD OBSERVE THE DAMAGE TO MY CAR THE CAR IN FRONT OF ME. WHEN I DID SO THE CAR ACCELERATE AT FULL SPEED IN REVERSE GOING BACK DOWN THE HILL AND HEADED STRAIGHT FOR A DRUGSTORE. THE CAR WAS MAKING A WHIRING SOUND, LIKE WHEN YOU REV UP THE ENGINE. I PUSHED THE BRAKES TO THE FLOOR BUT THE CAR WOULD NOT STOP BUT KEEP GOING FASTER! I PUMPED THE BRAKES SOME MORE BUT IT WOULD NOT STOP. WHEN I SAW I WAS HEADED INTO THE STORE, I TURNED THE WHEELS TO AVOID IT AND TRIED BRAKING AGAIN WITHOUT STOPPING. I FINALLY HIT THE STOP ENGINE BUTTON BUT NOT BEFORE THE CAR HIT A PARKED TRUCK IN THE STORE LOT WHICH STOPPED IT. IT WAS THE MOST FRIGHTENING EXPERIENCE I HAVE EVER HAD. I AM NOW AFRAID TO GET INTO A CAR. I WAS TOO UPSET TO TAKE PHOTOS. I WILL LIST THE CRASH REPORT IN THE FILE BELOW. *TR *BF *TR

REAR WINDOW VISIBILITY IS SERIOUSLY HAMPERED BY INTERIOR REFLECTION ON INSIDE OF REAR WINDOW. THIS VEHICLE HAS A LIGHT GREY INTERIOR COLOR AND THE BACK PACKAGE TRAY AND SPEAKER COVERS ARE ALSO LIGHT GREY. THIS LIGHT GREY COLOR IS REFLECTED ON THE INSIDE OF THE REAR WINDOW GLASS. WHEN LOOKING OUT THE REAR WINDOW USING THE INSIDE REAR VIEW MIRROR, THE REAR WINDOW LOOKS AS IF IT IS EXTREMELY DIRTY OR FOGGED. THE CONDITION IS WORSE WHEN SUBJECTED TO SUNLIGHT. AT PRESENT, WHILE AWAITING IF/WHEN A REPAIR/MODIFICATION WILL TO BE MADE BY THE SELLING DEALER, I HAVE LAID A BLACK TOWEL ON THE PACKAGE SHELF AS A TEMPORARY REPAIR. THE BLACK TOWEL HAS VIRTUALLY ELIMINATED THE REFLECTION AND PROVIDES CLEAR REARWARD VISIBILITY. TOYOTA IS AWARE OF THIS VEHICLE'S CONDITION AND THE DEALER HAS FORWARDED PICTURES TO TOYOTA SHOWING THE EXTENT OF THE VISIBILITY IMPAIRMENT. UNFORTUNATELY, ANY OTHER AVALON WITH A LIGHT COLOR INTERIOR WILL HAVE THE SAME DEFECT.

The steering tilt lock mechanism is failing. Vibrates loose while driving. It is a non-wear item. Toyota had to recall 2009-2012 models of Avalon for the same problem. My vehicle is a 2015 and is out of warranty and only has 50,000 miles. I did have a service center check it and they confirmed the problem. You can repair this non-wear item you must replace the complete steering column assembly. With parts and labor the cost is @ $1500. Whatever they did to redesign the mechanism since the 2012 model year to fix the problem was not effective. Toyota responded to my letter and declined to take any responsibility.
