2003 Cadillac CTS recalls 4

Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do

Electrical system: ignition

14V394000554,328 vehicles affected

The problem
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. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
The risk
If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
The fix
GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 15, 2014. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14172.

Service brakes: hoses, lines / piping, and fittings

10V105000139,131 vehicles affected

The problem
General motors has notified nhtsa of a defect in certain model year 2003-2007 cadillac cts vehicles currently registered in or originally sold in connecticut, delaware, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, washington d.C., West virginia and wisconsin. Some of these vehicles have a condition in which the front brake hose fitting at the caliper may corrode due to snow or water, containing road salt or other contaminants, entering and being retained in the routing sleeve. If the fitting corrodes significantly, the brake hose-tube interface may develop a leak.
The risk
The brake hose-tube interface may rupture suddenly without prior warning and increase vehicle stopping distance may occur increasing the risk of a crash.
The fix
Dealers are to replace both front brake hose assemblies free of charge. The safety recall is expected to begin during may 2010. Owners may contact cadillac at 1-866-982-2339 or at the owner center at www.Gmownercenter.Com.

Equipment: owners / service / other manual

03V2500001,707,825 vehicles affected

The problem
Certain minivans, passenger and sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 225, "Child restraint anchorage system." The owner's manual does not explain the meaning of the location symbols for the child restraint lower universal anchorage system.
The risk
This does not meet the requirements of the standard.
The fix
Owners will be provided with a supplement for their owner's manual. This supplement describes and shows the location symbols for the child restraint anchors that are located in the vehicle and on the child restraint or booster cushion. Owner notification began august 18, 2003. Owners should contact buick at 1-866-608-8080, cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, pontiac at 1-800-620-7668, or oldsmobile at 1-800-630-6537.

Steering

03V11500047,835 vehicles affected

The problem
Some passenger vehicles have a condition in which the intermediate steering shaft bolt may be loose.
The risk
An improperly tightened bolt could loosen, resulting in separation of the upper and lower steering shafts causing a loss of vehicle control. If this happens while the vehicle is moving, a crash could result without prior warning.
The fix
Dealers will inspect for the presence of the intermediate steering shaft bolt and ensure that it is tightened to the proper specification. Owner notification began march 20, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact cadillac at 1-800-458-8006.

shredded, I called and got it towed to the nearest place I could to get it looked at. When replacing the serpentine belt they said it'd be good to check the timing belt as well just in case. Upon checking it they noticed pieces of serpentine belt had gotten inside of there somehow causing the timing belt damage. With this type of engine if timing belt gets ruined 98% valves and pistons kiss which causes bent valves on the head. I was told the car would not run anymore unless I put a brandnew engine in and they wanted to charge me 6000 for that, I looked up a used engine on ebay for 650 they still wanted 3000, I don't have that kind of money sitting around and have been suffering without my vehicle since this happened. I've missed work and am lucky me or child weren't hurt during this situation. I called the local cadillac dealership this morning and explained what happened the guy I spoke with was very rude and told me theres nothing the could do to help me, I asked about the recall again and he said I need to call corporate I dialed the number he gave me and didn't get thru to anybody. Lucky I looked up the number myself explained the situation to them they gave me a case # and said I'd be contacted within 1to 2 business days by a senior advisor. Bottom line is I'm still stuck without a working vehicle due to this recall.

I was driving down hwy.78 West when the lights first came on and continue to do so at random times. My wife is short so she is almost up to the steering wheel. I also have a 5 yr old daughter. I am in constant fear and worry that the airbag will deploy prematurely or when hitting a small pothole. I have checked for any recalls from the manufacturer and there are none. I would truly appreciate any assistance I can get to correct this problem. It is an accident waiting to happen.
