Open the full vehicle complaint log (all categories)WHILE DRIVING THE CAR COMPLETELY SHUTS OFF AND I'VE HAD CLOSE CALLS. I WAS DRIVING ON THE HIGHWAY AND SIDE STREET WHEN THIS HAPPENED.
IVE BEEN COMPLAINING ABOUT THESE PROBLEMS SINCE I PURCHASED CAR. I HAVE A 2008 BUICK LACROSSE. SHAKING ,NOISES, WHEELS, TURN CAR ON AND IT TUNS OFF., IVE HAD 3 ENGINE LIGHTS COME ON SINCE IVE HAD CAR. P0300 CODE. PAID 495 FOR THIS CODE.VERY UPSET TO FIND OUT ITS A RECALL ON WHAT THEY FITS. AND THE CALL IS MESSING UP AGAIN.IVE ONLY HAD CAR BACK 6 DAYS. ROTORS HAVE A RECALL ON THEM. NO ONE HAS SENT ANY NOTICE. THIS NEED TAKING CARE OF ASAP. TURNING STEERING WHEEL AND HERE ALL KINDS OF CRACKS. TURN HEATER ON AND IM FREEZING FOR 30 MINS. BEFORE GET ANY HEAT. IM SCARED I MIGHT HAVE A WRECK. I CANT ROAD AT NIGHT WITH LIGHTS.
THE TRANSMISSION FAIILED WITHOUT NOTICE. HOPE IT DOES NOT HAPPEN WHILE AT A STOP LIGHT. I JUST BACKED INTO A PARKING SPACE WENT TO PULL OUT AND WAS NOT ABLE TO PUT THE CAR IN ANY DRIVE GEAR AT ALL. VEHICLE MILAGE 79850 MILES.
THE ENGINE DIED WITHOUT WARNING AND WOULD NOT RESTART. FORTUNATELY, I WAS ON A QUIET STREET AND SO I COULD STOP CURBSIDE. LIGHTS ETC. WORKED BUT POWER STEERING, POWER BRAKES, ENGINE WERE ALL DEAD. THE CAUSE WAS A CRACKED IGNITION COIL THAT SHORTED AND "FRIED" THE IGNITION MODULE. THIS WAS AN ORIGINAL-EQUIPMENT PART, PROBABLY A DELPHI GN10123 (FROM MY INTERNET RESEARCH; I COULD BE WRONG). HAD THIS HAPPENED ON A HIGH-SPEED ROAD, THE RESULTS COULD HAVE BEEN DISASTROUS. *TR
FOR THE THIRD TIME, THIS VEHICLE HAS DIED AT A STANDSTILL FOR NO APPARENT REASON. IT WILL BE PERFORMING WELL UNTIL PARKED. AFTER A SPAN OF TIME, IT WILL NOT RESTART. WHEN THE KEY IS INSERTED INTO THE IGNITION, THE MOTOR WILL NOT CATCH OR TURN OVER, THE KEY WILL FREEZE OR LOCK IN THE IGNITION IN THE "ON" POSITION, NOTHING IN THE VEHICLE CAN BE OPERATED - GEAR SHIFT, RADIO/PLAYER, DOOR LOCKS, TRUNK LID, ETC., ETC. ETC. THE CAR IS COMPLETELY SEIZED UP. INSPECTION WILL DISCLOSE THAT BATTERY, INCLUDING BRAND NEW BATTERY, IS DEAD ( NO VOLTAGE WHATSOEVER). ONLY WAY TO RESTART VEHICLE IS TO RECHARGE BATTERY. THIS HAS HAPPENED THREE TIMES OVER SPAN OF 9 TO 10 MONTHS. WHEN BATTERY IS RECHARGED, VEHICLE WILL OPERATE FOR MONTHS UNTIL IT IS DEAD AGAIN. SOMETHING IS DRAINING THE BATTERY, BUT THERE NO LOGICAL EXPLANATION; NOTHING SUCH AS RADIO, LIGHTS, ETC., IS BEING LEFT ON. SOME AUTO REPAIR PEOPLE BELIEVE THERE IS A SHORT IN THE CAR'S WIRING HARNESS; OTHERS BELIEVE THE DEFECTIVE IGNITION SYSTEM IS AT FAULT. *JS
