The contact's wife owns a 2014 GMC Yukon XL. The contact stated that on several occasions, the vehicle failed to start with the key in the ignition. The failure persisted and a yellow anti-theft warning symbol was displayed on the instrument panel. The contact stated that on one occasion the vehicle failed to start after several attempts and the contact became trapped inside the vehicle for approximately 5-6 minutes and was unable to unlock or open the doors. The contact attempted to use the remote and the key to unlock the doors but there was no electrical functions available. The contact stated that the temperature was very hot inside the vehicle, and he was starting to be deprived of oxygen due to the excessive heat. The contact’s wife who was inside the residence was able to unlock the vehicle from outside after several attempts of pressing and pushing the door handle, the key, and the remote. The contact stated that after the door was unlocked, the contact jiggled the key inside the ignition switch and the vehicle started. Medical attention was not needed; however, the contact stated that the failure could have been fatal if he did not have the cellphone to call for assistance. The contact eventually restarted the vehicle and drove to the dealer. The contact was provided a diagnostic fee and the vehicle remained with the dealer. The manufacturer was not yet notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was 120,079.

State Farm is investigating the accident to see what, if anything, malfunctioned in my braking system. I ran a red light but when I pressed the brake upon approach of the red light my brakes didn't catch and so when I pressed them, I kept going at the same speed. I was going between 30 and 40 miles per hour I believe. Three cars were involved. I have a sore neck, chest, and burn marks in my neck region. I suspect my truck will be totalled. We performed routine maintenance on the vehicle. It had a little over 100K miles on it at the time of this wreck. There is not a recall on braking for 2014 models, but I see there is one for 2015.

I have an outstanding recall on my 2014 Yukon. This recall is several years old. As far as I can tell nothing has been done on this recall. This is a safety recall! Previously I owned a 2008 Chevrolet Suburban with the same recall on it. I was told that no parts were available for the repair. I repeat this is a SAFETY recall!!! We had a wreck in the 2008 chevrolet suburban which deployed the airbags. Lucky for us the airbag worked properly. My wife was setting in the front passenger seat. If the igniter had exploded she would have been seriously injured or killed. We bought this Yukon from Carmax. The car came to us from Alabama. Hot and high humidity. As I understand it these are the conditions that make the igniter more likely to explode. Please do something on this recall.

WAS INVOLVED IN AN ACCIDENT UNABLE TO STOP IN TIME. UNINOW IF THIS IS RELATED TO THE BRAKE POTENTIAL RECALL BUT I HAVE NOTICED POTENTIAL STOPING DISTANCE CHANGES WHEN USING THE VEHICLE FOR LONG PERIODS I ASSUME IT IS JUST FROM USE. FIGURED THIS INFORMATION WOULD BE USEFUL WITH THE CURRENT INVESTIGATION

AFTER SWITCHING TO PASSING LANE AND SEEING TRAFFIC IN LANE AT STANDSTILL I SWIFTLY JAMMED ON BRAKE PEDAL. BRAKES FAILED TO PROVIDE ADEQUATE STOPPING ABILITY AS THOUGH THEY WERE COATED WITH GREASE. DESPITE HAVING WELL IN EXCESS OF 100 FT THE VEHICLE WOULD NOT STOP. REAR ENDED VEHICLE IN FRONT WITH ABOUT 12K IN DAMAGE TO FRONT OF THE VEHICLE. AIR BAGS DID NOT DEPLOY. ORIGINAL ROTORS AND PADS WERE REPLACED AFTER EXPERIENCING SEVERE BRAKE FADING WHEN HOT PRIOR TO ACCIDENT. DRILLED AND SLOTTED RACING ROTORS WERE INSTALLED. AFTER THE VEHICLE WAS REPAIRED AND PLACED BACK ON THE ROAD, I TESTED WITH THE SAME BRAKES WITH A HARD STOP FROM 80 MPH. THE BRAKES WORKED SO WELL THE FORCE OF THE STOP WAS PULLING ME OFF MY SEAT. SEVERAL WEEKS LATER, I WAS CUT OFF BY ANOTHER DRIVER ON THE HIGHWAY DOING ABOUT 40MPH LESS THAN I WAS. I JAMMED ON THE BRAKES AND AGAIN THERE WAS INSUFFICIENT BRAKING LIKE BEFORE EXCEPT NO COLLISION. ONCE MORE I TESTED AT A HARD BRAKE FROM 80 MPH AND AGAIN IT STOPPED EXTREMELY WELL. APPARENTLY THE FAILURE OF SUFFICIENT BRAKING CAME WITH APPLICATION OF ABS SYSTEM OTHERWISE THE STOPPING POWER WAS EXCEPTIONAL. I STRONGLY URGE INVESTIGATION OF GM ABS BRAKING. I AM A PROFESSIONAL DRIVER WITH IN EXCESS OF 4 MILLION MILES WITH ALL CLASSES OF VEHICLES IN ALL EXTREMES. THE WORST DAMAGE I EVER HAD ON THE HIGHWAY WAS A BROKEN HEADLIGHT IN 1975 UNTIL THIS ACCIDENT. THE ACCIDENT SHOULD NOT HAVE HAPPENED AS MY REACTION WAS TIMELY AND THE DISTANCE TO STOP MORE THAN ADEQUATE. THE AIR BAGS FAILED TO DEPLOY DESPITE THE ENTIRE NOSE OF THE VEHICLE BEING DESTROYED AND PUSHED BACK TO THE ENGINE BLOCK. *TR

I HAD A FRONT END COLLISION AT 25 MPH WITH A PARKED CAR. MY AIRBAG(S) DID NOT DEPLOY. THE ENTIRE FRONT END OF MY CAR WAS DESTROYED. THE HOOD WAS CRUMPLED AND BOTH FRONT QUARTER PANELS DAMAGED. THE FRONT DOORS ARE NOT EASILY OPENED DUE TO THE QUARTER PANEL DAMAGE. IT IS HARD FOR ME TO UNDERSTAND HOW AN IMPACT AT THE SPEED I WAS TRAVELING AND THE LOCATION OF IMPACT DID NOT CAUSE THE AIRBAG(S) TO DEPLOY. I HAD TO BE TRANSPORTED VIA AMBULANCE FROM THE SCENE AND SUFFERED A CONCUSSION FROM MY HEAD SLAMMING DOWN ON THE STEERING WHEEL. *JS
