Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Passenger rear brake line corroded and burst causing loss of brake fluid. Due to the loss of brake fluid, I lost 95% of brake pressure making it very difficult to stop. Only reason I say 95% is because the brake system is designed to still function in limp mode, but still terrifying while driving. The problem was discovered by myself as I was a certified technician for over 10 years for this brand. The vehicle hasn’t been looked at by anyone but myself. The brake lamp indicator did come on shortly before the line burst.”

NHTSA complaint #11500035, filed 2023-01

“While driving the brakelines were affected and brakes weren't working any longer. I see online there is a recall for my specific car. The recall is for corrosion of the brake lines in specific snow states and the use of salt. I live in CT and bought the car from a private owner. I looked to see if the car was ever serviced for the recall and I am finding nothing on it. Thr exact spot indicated in the recall is exactly where the brake lines corroded so much that there is a hole now. Thanks for your time.”
