The above vehicle was recently in a shop for brake pad replacement when my mechanic discovered that there was a leak of lubricant in the rear end of the automobile. Upon further inspection he discovered that the rear axle pinion seal was leaking. The automobile has just 60,000 miles. After checking the NHTSA he found that a recall, gm recall number 07204 had been issued for this very problem. However, when I presented the vehicle for repair this morning at marion Chevrolet Cadillac they refused to cover the problem under the recall stating the VIN does not meet the recall range. I find it untenable that gm could recall nearly 300,000 vehicles for this very issue but refuse to cover an identical problem in a vehicle that does not meet the VIN range set by gm.
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).
All cars and suvs manufactured by gm's Cadillac division have been built with instrument panels (ips) that do not allow the driver to know how fast he is going above a certain speed when the speedometer has been calibrated in kmh. The us is now a metric country and all measurement systems should be in both english and metric calibration. Every other domestic and foreign manufacturer is required by law to have ip speedometers that read in both systems. These speedometer faceplates have a larger mph reading and a smaller kph one below it so that drivers always know how fast they are driving all the way up to the top speed of the vehicles. But not so Cadillac. Cadillac only has one numeric reading on the speedometer face. The speedometer face therefore reads to 160 in the case of the Cadillac srx for example. However if the driver decides to switch the ip to metric he will not know how fast he is going above 160 kph which is 100 mph. You might say so what since you are not allowed to legally drive 100 mph plus in the us. Perhaps, but many people take their cars to mexico, canada and europe - all places where those speeds are either tolerated or in some cases legal. If Cadillac continues to sell vehicles with this quirk they should allow as an option the ability to get the kph graded speedometer (ie the one sold in canada, mexico, europe, china, japan, australia and everywhere else). It is a safety issue to always know your correct speed in the two systems mandated by us law.
Vehicles voice recognition & blutooth telephone system are unstable/unusable. Vr system recognizes stated cxommands approx. 10% of the time. System miss-identifies commands 90% of the time causing improper/incorrect execution of wrong command. Servicing dealer states this is a known issue with all owners and there is no service bulletins or fix actions at this time or known. Cadillac customer assistance center in response to a written letter infomrs they have no knowledge of this being a major concern and inferred it was a "user" issue in properly operating the system. Research among Cadillac owners boards shows a large sample of owners with similiar/same concerns. Blutooth system was 100% unrealiable with a qulaifying cellular device and completely unusable. With a second device system partially works but user also experienced a system "lockup" of all user features including hard kets, touchscreen and steering wheel controls while driving at highway speeds when using the bluetooth feature on one occasion. Vehicle had to be stopped and completely shut down to remedy situation which has not as yet repeated itself. Again Cadillac was unable to assist and the ccac representative said only a "few" phones actually worked with the system that they knew of. Vehicle is designed around the vr feature for drivers use and this has proved to be a major area of concern for us. Still working with Cadillac but unsure of what resolution may be. . .
Pretty much the same as complaint # 10120320 contact states the vehicle's voice recognition system is not working. If you state a command a majority of the time it will execute a different command. Once a command has been executed it is difficult to stop the command. The manufacturer has issued a file number(gm file no. 1322945605) but not yet fixed the problem.
