Example complaints

“My car has been intermittently displaying ABS vsc and brake warning lights. When they are on there is no brake regeneration. The lights have come on and gone off and now are on again. Getting obd code c1391 (abnormal leak in accumulator) my vehicle is just a small amount over mileage to cover this under enhanced warranty but Toyota knows they have a brake accumulator problem and wants 3k to fix what should have been a recall long ago. Have called and Toyota will not help.”
NHTSA complaint #11154586, filed 2018-11, 160,000 miles“The combination meter went out on my Prius. On multiple occasions, the dashboard went blank. When this happens the driver is unable to see the speed or any other safety lights. The most alarming issue was when our vehicle would not shut off after the dashboard went blank. When we arrived at our destination we were unable to turn the vehicle off with the push button 'start.' the car continued to run on reserve even after the battery terminals were disconnected. …”
NHTSA complaint #11048078, filed 2017-11, 198,000 miles“My 2009 Toyota Prius, since I first purchased it april 2009, the anti-lock brakes seem to fail. When I brake and hit a bump in the road the anti-lock brakes engage and release the brakes. It feels as if I am sliding on ice. I discussed this with the Toyota dealer last month, who dismissed this as normal anti-lock brake activity. I feel these cars need to be recalled and repaired.”
NHTSA complaint #10341484, filed 2010-07, 25,000 miles“I was turning left and was hit by an oncoming car. Most damage done to the front right. The car was totaled. I was going about 5-10mph though the oncoming car was going approximately 40mph. The firemen, police and insurance adjuster were all very concerned that the airbags did not deploy. My babies were safe in the backseat thanks to their car seats. I had to go to the hospital and suffered a concussion. We just had our car tuned up at our local Toyota dealership not even 6 mos ago. They did not say anything about a concern with the airbags.”
NHTSA complaint #11268210, filed 2019-10, 103,000 miles“Display for odometer, speedometer and gas gauge goes out intermittently.the 'combination meter' (a.k.a. 'instrument panel' or 'cluster', the thing you're looking at in front of you) is bad. There are several electrical components in the circuit board that control how it 'powers up', and they fail. Lacking the ability to power up, the display goes black. Joe myers quoted us $1156 for repair, and one week repair time. Service advisor said that repair part is fixed part so that problem will no longer occur. We must drive the vehicle till we replace it. …”
