This complaint pertains to GM recall #14405-2. also listed under the National Highway Traffic Safety Administration campaign id number of 14V542. Here is my issue: When a manufacturer, in this case Cadillac, issues a recall that is an inconvenience to their customers, why doesn't the government require them to give a loaner car and/or additional compensation to the vehicle owner to cover the cost and hassle of taking off work and getting a rental car to use? I asked the dealership, the Cadillac customer service line representative, ahmed, and the Cadillac customer service supervisor, michelle for a loaner car and the request was denied. I think that as part of the cost of recalls the manufacturer should limit the customer's inconvenience to an absolute minimum. Please consider requiring manufacturers to provide a loaner car when a recall is issued in the future. This is not a "free" repair if I have to take time off of work and pay for a rental car. Also the need for this repair has been determined by the government and/or the manufacturer's lawyers so that further cost and lawsuits will not be incurred. You would think that the manufacturer would want to limit delays in getting repairs done due to additional costs and inconvenience to the owner of the vehicle.

Air bag light constantly stays on, along with the check engine light. Seat belt chime constantly rings with the seat belt connected. Gas low notification light does not come on until on empty. No heated seats. I think the ECM needs to be reset.sun roof goes up but not slides open. Passenger side door won't open.automatic car starter doesn't work. 2 years ago, my son in law, started this car in below zero temp and it started on fire. He put it out and restarted it and it was ok. Something makes noise occasionally for no apparent reason.

4/14 - car was shutting off intermittently, pulled over in hotel parking lot and a gentlemen came up to car to tell me that it was smoking, got out and there was a fire at the rear of the car. Ran into hotel and got fire extinguisher to put it out, had towed to repair shop. There determined that the terminal on the top of the fuel pump over heated and melted a hole in the top of the pump, causing fuel to leak out and catch fire -$6000 worth of damage, only used parts available to fix car. 8/14 recall was released about fuel module and harness. 6/15 - called dealer about unrelated issue (door lock), VIN# was ran and was told parts were available to fix recall. I mentioned I did not receive the letter that parts were available and was told dealer had to order them, 4 days later parts came in and work was scheduled. Car was there for 10 days "having trouble getting parts". when car was picked up the fuel gauge was now off only reading 3/4 when full and check engine light on. Told harness is not available to finish recall and it will take care of both problems. This safety recall is beyond a reasonable amount of time for repair. The dealer should not have torn into car if all parts were not available. Car is due for inspection 9/15 and as it currently stands it will not pass inspection due to the check engine light being on and now the gas gauge does not read at all. This has been a huge inconvenience and am very displeased with the lack of support from Cadillac and the dealership. I now have a vehicle that I can not get parts to fix recall, will not pass inspection, and I can not sell it or trade it in.

The contact owns a 2006 Cadillac Sts. While driving at 60 mph, the engine stalled. The vehicle was taken to an independent mechanic who diagnosed that the fuel pump wiring needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.

The fuel delivery system has been failing in the same manner that I have seen many other Cadillac owners have gotten repaired through a recall already in place. Every single time I put gas in the tank the car refuses to turn on with the first attempt. The only way to get the car to turn on is after multiple attempts and finally enough fuel gets delivered to the system. Similarly, the car will hesitate or feel like no gas is being delivered to the engine while driving on the highway. Often, it will cause a dramatic drop in speed causing a dangerous situation. GM definitely needs to take this into consideration because it is faults equipment rather than wear and tear. Also, there seems to be a some major issue with the oil system in the car. One week after a synthetic oil change, there is over 1 quart of oil missing in the reserve. There has been over 4 quarts missing at a time.

The engine shut off when I was driving on a side street at 20 mph, and also shut off 5 times as I was driving on the highway at 65 mph. The cluster panel turned off, but the radio stayed on. The odometer showed a message engine control module (ECM). I pulled over, put the car in park, and restarted the vehicle each time. The Cadillac dealership said that rear axle pinion seal was the only recall for my Sts, but I am experiencing NHTSA campaign number: 06V020000, and NHTSA campaign number: 06V007000 also.

Car stalled on busy street and would not restart. After later investigation it turns out that the electrical connector in fuel module assembly shorted out and melted the plastic connector. It also melted part of the bottom side of the top of module. GM has recalled earlier models of vehicles for the same situation. I believe this to be very dangerous for multiple reasons:stalling on busy street and not being able to restart, fuel leaks due to hole melting in module top, and its a fire hazard.

After purchasing a used 2006 Sts AWD from Cadillac NJ in December 2009, wife noticed while making right hand turns on smooth pavement, car seems to stall temporarily not allowing me to accelerate for a few seconds and message traction active is displayed. January 18, 2010, I brought the car back to dealership to complain. They said prob bad gas in lines. Put new gas in and gas treatment for water in tank. Did that, didn't help. February 1, 2010 I returned to dealership to complain it was still doing it on occasion. I asked if there were any complaints on this vehicle. Got a no response. May 2010 brought car back to dealership to complain. By this time my wife has refused to drive it for safety reasons (people think she is letting them into oncoming traffic when car slows down). Looked on internet and found other complaints. I was told GM engineering is aware of issue and are working on solution. Made complaint to GM in Sept 2010 was told software update will be ready in 2 months. After getting dodged for 2 1/2 more years, made second complaint to GM April 2012. GM executive stated I can use a rental due to the seriousness of the condition losing power while driving. They said it was fixed. A week later it started again. GM executive and service manager of Cadillac called to say that the car was designed that way. There is no fix on it. I told them the 2011 Sts rental I drove did not have any problem losing power while in a turn. They said it is a different system. I said "so there was a problem with the old system". I was let out of the door with an offer from GM exec's, $4,500 off price of a new car at their dealership. I asked, what about safety? I told them I own a car that my wife refuses to drive due to loss of power. I only drive car because my wife drives my truck. GM knows of this safety issue. Service said problems on 2006-07 Sts's. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

Catalytic converter failed at approximately 83,000 miles. Check engine light comes on and the manufacturer and the dealer replaced the converter. At 93,000 miles, received check engine light warning again and the code indicates that the catalytic converter is a problem. The side affect is that the car lacks power when having a need accelerate. GM has recalled the 2005 converter, but not the 2006.
