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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

As I was turning into a parking spot to park my car, the car accelerated on its own and ran into a concrete wall. I have had issues with this car's programming, including when I took my car in to get fixed after the safety recall in January '16. As I realized the car was accelerating - and pushing on the brake would not stop it - I lifted the emergency brake. The crash ultimately stopped the car - not the brake or emergency brake, and the airbag deployed. Less concerned about the damage to the outside of the car, and more concerned that I had zero control over the car and any ability to stop it.

Harsh vibration in cabin similar to an engine misfire occurs randomly near idle or immediately after ignition. The dealership and manufacturer have been made aware of this concern and were unsuccessful in reproducing or isolating source of the vibration. Video documentation of the failure during its occurrence has been provided to both parties and has been forwarded to the senior regional engineer for analysis. Current owner has an open vehicle repurchase claim under lemon law with the manufacturer pending investigation of fault.

I initially had issue getting into and out of the 3rd and 4th gear (manual transmission car). I could feel gears grinding during shifting (with the clutch fully depressed). The dealer replaced the third gear. After the fix, the car now has difficulty getting into and out of gear 2 and 3. this problem is intermittent but is more noticeable after the initial start-up of the car, especially if the weather is cold (50F or colder). With the clutch fully pressed, I can still feel the gear rotating and grinding during shifting. When the car is cold, a lot of force is needed to shift the car into 2nd and 3rd gear. The shifting issue is less noticeable when once the car has been operating for 20mins.
