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.

My engine leaks oil from the seals. It was always dealer maintained for regular maintenance with low mileage. It started 3 years ago. I noticed you recalled other vehicles for this problem. My engine is a V8. Regular oil changes etc. It continues to leak. Dealer wants $2,500 to fix seals. The way I drive it with low millage of 60,000 miles it should not have leaked. Just read about recall of other GM cars on 27 Oct. 2015.

After taking off from a stop sign, I drove up over about 1 1/2 inch vertical rise in the pavement (small bump). The engine and electrical systems shut down. I lost power stirring and power brakes. I got stopped and restarted the engine. This occurred about 3 days after I had taken my car to the GM dealer for repairs covered by GM recall 14299, "unintended ignition key rotation". my key did not rotate. Yesterday April 2, 2015 when driving 45 mph on a state highway, the engine stopped again without hitting any bumps. I was able to coast, put the car in neutral, and restart the engine, before the car behind me could hit me. There was no shoulder to pull off.again there was no key rotation. I called my GM dealer after the first occurrence and was told I would have to pay for a new ignition switch or what ever was causing the problem. The recall only removed all other keys from the ignition key ring. This is a very dangerous defect that GM needs another recall to fix this sudden engine and electrical system shut down because if there is a crash the air bags will not deploy. Also lost of power steering and power brakes makes control of the car very difficult.

Notified last summer (2014) about recall...in September (2014) notified to schedule an appointment for the repair...have called the local dealer several times....dealer does not have the necessary materials to correct the problem. Have experienced several times the ignition turning off....(the reason for the recall)...fortunately have not had an accident. What is holding up the repairs" why send a letter instructing us to now get it repaired when the local dealer does not have the materials needed" very frustrating!!!!

I was driving at approximately 60 mhp on I77 North - without notice of any kind it became very difficult to steer my vehicle and I lost control as well as all power & acceleration. All of this happened so fast but I looked down and noticed several dash board/warning lights on. These lights normally only go on for a second or so when starting the car. Having no power or acceleration I was able to navigate my car to the side of the road with out an accident but immediately noticed that my ignition was already turned off. The ignition key was not all the off - just in the position as if I was parked and wanted to listen to the radio. Once pulled over I placed the car in "park" turned the key all the way off and restarted the car. It started right up. However, now both my "service engine soon light" and "air bag" light stays illuminated at all times. They do not go out once the car is started. I am not able to notice any difference in the performance or handling at this time but am concerned with the lights remaining on at all times when driving as well as the safety of the air bags.

Engine shuts off without warning, sometimes when stopped and/or while moving.this has happened about 4 times in the last year. Suspect a defect ignition switch and/or a crankshaft position sensor.
