I tried to explain to the dealership that unaware of the recall my cars breaks had failed and crashed my vehicle. They said the only thing that was affected was the key. I had told her that the result of my crash was from my breaks not working due to the recall. She told me no that that wasnt affected. I just want my car to be safe on the road as i have kids, and family that ride with me regularly.

Takata air bag, do not know if that item is in my car but they say it is. Also like so many northstar engines there is trouble with the head gasket, and according to the hydrocarbon block test, mine must be replaced. In order to replace it, the engine and power train must be removed, at my expense. Due to this issue, my car continues to try and overheat after about 29 miles of driving. After listening to those folks on the cadillac forum, I have been lead to believe, the overheating issue may be, partly the fault...

of the fine thread head bolts and or studs. Many mechanics I have spoken with have said that I need a new engine, although the folks on the cadillac fourm have said that time-serts, or the larger studs/bolts might fix the issue. Never the less, with each cadillac deville dhs with the northstar engine I read about, the same issue exists for almost all of them, which indicates to me that there was an issue in the original design of possibly not using a large enough bolt/stud to begin with. Either that or cadillac may have had a planned obsolescence type thing to get the drivers to keep replacing their automobiles. And they say recalls are not covering this design flaw....

As a disabled vietnam military veteran my 1993 cadillac sedan deville when driving on the highway or anyplace will shut down the engine with no warning. Looking for answers to why. This is very dangerous
Tl* the contact owns a 2001 cadillac deville. While driving various speeds, the steering wheel seized, the vehicle stalled, and the battery warning indicator illuminated. The contact mentioned that the failure occurred several times. The vehicle was taken to two different dealers for diagnostic testing, but a failure code could not be located. The contact spoke to an independent mechanic who informed her that the failure was due to the failure of the upper and lower crank shift position sensors, which caused the engine to stall. The sensors needed replacement. The vehicle was not repaired. The manufacturer was made aware of the failures. The failure mileage was approximately 103,000.
Engine began overheating and took it to our mechanic who replaced the water pump. Engine continued to overheat and same mechanic replaced all of the upper seals. Eventually, a pressure test and camera insert by my mechanic confirmed a blown head gasket. Confirmed that result with pepe cadillac in white plains, ny. Checked the price to have the head gaskets replaced, but since this engine has to be removed from the bottom of the vehicle, the costs are outrageous and the only acceptable fix for these aluminum...

heads are bolts rather than the gm serts. Bad engine design by gm since their bolts were too short and the bite was not large enough in the block to prevent the head gaskets from blowing. Sad epitaph for a car with only 65k lightly driven miles on it having spent all of it's off road life in our garage. After much research, I was able to confirm that this is an inherent problem with the northstar engine during that period and was finally solved after 2004. Gm knows about the engineering northstar engine problem but refuses to accept responsibility for it.

The car while turning intermittently dies and looses any acceleration stalls and most of the time starts back up when lifting foot of the gas and sometimes dies. Also the car accelerates on its own sometimes very quickly. The car stalling while making a left turn got me t-boned by someone while making a left hand turn. I'm not the only one with this problem. This defect is going to get somebody killed.
