This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) notified the agency on July 2, 2014 that they are recalling 554,328 model year 2003-2014 Cadillac CTS vehicles manufactured August 16, 2001, to April 28, 2014, and 2004-2006 Cadillac SRX vehicles manufactured March 20, 2003, to August 11, 2006.

They played a [XXX] man made him get a timing chain for Morris Cadillac. I have several receipts from the vehicle being serviced because of the faulty windshield washer heater system that was supposed to be disabled caused an electrical short in the vehicle because it was not properly sealed water got in the wires and caused the computer to be fried this happened before the car still only has 67,000 miles and they won’t even take it in. The car stopped in the middle of the road almost killing everybody. I’ve had several technicians explain that it’s because of the faulty. Recall that they did not fix that is still exposed. Maybe they had a worker that was fired in 2017.”

Engine

22 reports2 fires
“Vehicle Purchase Statement – Top Tier Auto I, [XXX] , purchased a vehicle from Top Tier Auto on [XXX]. The vehicle details are as follows: VIN: [XXX] Warranty: 30-day coverage for the transmission and engine After owning the vehicle for only 15 minutes, I entered the freeway, and the car began to shake violently. Shortly after, a gentleman driving behind me alerted me that sparks and fire were falling from beneath the car. I immediately pulled over, just before the engine burst into flames. The Columbus Police Department responded to the scene and had to extinguish the fire. This incident occurred within minutes of purchasing the vehicle, despite the supposed 30-day warranty covering the transmission and engine.”
