“My car will lunge forward when idle and with my foot on the brake. It's very dangerous and has nearly caused an accident on several occasions. This has been occurring since I bought the car used in 2013.”
NHTSA complaint #10981314, filed 2017-04, 30,000 miles“Purchased (new) - july 4th, 2011. One month in, the front driver tire blows out on the 55 freeway in costa mesa. The car is driven to the dealer the next day - to have a tire placed on. The price was surely surprise surprise - $250.00. We push to know why the tire was so expensive, it's because the size is new for this size vehicle and there's one maker of the tire. Bridgestone. We pay for it begrudgingly, and go about our way. February 6th, 2015, 3 years, 6 months of owning the vehicle. …”
