1 Vehicle Speed Control problem

Failure Date: 10/06/2018

Driving 70+mph on freeway in fast lane. Car stop accerlating and no rpm the steeling wheel then locked on me while in the fast lane on freeway. I immediately pulled over restarted the car and was able to move safely off freeway.

2 Vehicle Speed Control problem

Failure Date: 04/02/2016

When the car is driving at 50 mph or higher a message is sent across the dashboard saying to "service stability system" I took it to a mechanic so sensors were bad and he could not find the issue, when this message appears on the dashboard at high speeds it feels like abs kicks in without me touching the brakes at all, so the car will brake on its own and almost caused a multi-car pile up because my car started braking on its own out of my control.

3 Vehicle Speed Control problem

Failure Date: 06/25/2014

While driving turning left onto an expressway entrance my engine shut down I believe it was the ignition switch. Ive taken the vehicle to the dealer numerous times and they can't seem to find a solution. I am in fear that one day this car will lose power at the wrong time and cause a serious if not fatal accident. I would like the problem fixed or a reimbursement to invest in a new vehicle before it is too late.

4 Vehicle Speed Control problem

Failure Date: 01/12/2014

When driving it would engage to stability mode and also service satbility. . However the car would get out of control and it would be as if you put you brakes on when you were in water. . . But no water and I hadn t put the brake until I had to. . Because it went out of control for a quick (but more frequent) time. . . I took it in finally and asked if there were any recalls becausewhen I purchased it in 2003 new. I had to have the shaft bolt fixed . . . Then I had to have the air bag serviced and they charged me for that another time. Then my seat motor went out. Etc. All within the 1st 5 years with low mileage too. So I've bee waiting to fix this since I am a widow and don't who to trust anymore. . . I was told this time it is leaking in the differential and thats why it runs rough and jolts when I put in gear. . . And the thermostat and 2 caps in front leaking . . . Who knows. . But tomorrow they will call me with the amount it is going to cost. . . Aporx. 13 hours of work. . . .

6 Vehicle Speed Control problem

Failure Date: 07/11/2012

We own a 2003 Cadillac Cts that we bought new back in late 2002. It currently has about 85,000 lightly driven miles. About 1 1/2 years ago, the engine become stuck at high revolutions. In other words, the car accelerated to high speed and would not slow down. Had to turn off the engine to regain control. We referred to this as a "throttle control" problem--although that may not be the correct terminology. It was repaired by the Cadillac dealer at that time (at considerable cost). Since then, the same problem has occurred two more times. It was repaired by the dealer about 6 months ago but the problem has now returned for a third time. The car is unsafe to drive as unexpected acceleration may occur at any moment. Most recently, the dealer claims that the problem is due to the engine control module (computer)--but it remains to be seen if that will indeed repair the problem. On another occasion, while on a short trip about 9 months ago, the engine began to run extremely unevenly--barely functioning. We limped into a Cadillac dealer who diagnosed the problem as two faulty coils. They replaced those (again as considerable cost) and the car ran well again--until this latest episode of unexpected acceleration where the engine becomes stuck at extremely high revolutions.

7 Vehicle Speed Control problem

Failure Date: 01/02/2012

I was driving home from work when this first happened. All of a sudden a loud screeching noise and the brakes would not stop in time. I had to pump the brakes to work. I took my car to Cadillac in arizona and they had it for 2 days and could not find an issue. I drove home that day with it and sure enough it did it while I was home. It had now began to jerk me to the right and left when I press on the brakes, scaring me thinking I am going to hit the car next to me. I took it to midas this time and they noticed a problem and said maybe its a wheel barring. They replaced issue duplicated itself shortly after. Since I did not have a second car or pay for a rental I had to take my car home to go back to work the next day. This problem is a safety hazard and I have even been pulled over because the cop asked why I was swerving while driving. I told the office its the code that comes up on my screen and it makes my car halt while driving and I can not control it. He stated that its a very serious issue and if another officer was on duty they might impound my car due to a safety hazard but he would give me a chance to take it home to go to the shop. I am almost close to trading in my vehicle and buying a new one, but not a Cts. If Cadillac can't solve this, the creator, who can? I am scared I'm going to veer off the freeway or hit a car on the way to work. I drive an hour to and from work everyday and my safety is the utmost concern to me and my family.

We have a 2003 Cadillac's Cts with about 77k miles. On 7-5-2010 as we were pulling into a parking spot in a shopping plaza at less than 5 mph, all of a sudden the car went to full throttle, jumped the curb, thru bushes, and onto the hood of the car facing us. Within a few weeks prior to this, while sitting at a red light with our foot on the brake, we notice what seemed to be the engine revving up. The car is in the shop now.
