The 2003 cadillac cts has various electrical problems, where the power/instrument panel display cuts out repeatedly. The safety concern that alarmed me enough to find this form has happened 3 times where I am driving on the highway and suddenly the car's power shuts off and the message display is to re-start the car. When this happened, I put the car in neutral, turned off the ignition and re-started the car (twice on the highway at higher speeds and once on a local road at lower 30 -40 MPH velocity. With no reason or warning.
2003 Cadillac CTS electrical complaints
Page 3 of 3: complaints 41 to 56 of 56, newest first, as owners wrote them.
While traveling at moderate speed vehicle began shaking violently and loosing power. The engine was missing on one or more cylinders. Dealer recommended replacing coil, sparkplug, valve cover gaskets and oil cooler. This seems to have been caused by a defect mentioned in cad cts tsb id # 1609265 dated 2005. This tsb states that the crankcase vapors and engine oil will vent through the cam/valve cover seals when the crankcase ventilation system becomes blocked. The oil on this vehicle evidently vented and leaked several places including into the ignition coils causing a short. If this had happened in interstate traffic at high speeds this could have caused an accident or if the oil had leaked on very hot surfaces possibly a fire. The tsb specified kits that were to be installed to prevented this from happening. Evidently, these were never installed on this vehicle.
2003 cts - service tracking system began to display and engage frequently. Took to local dealer and was told nothing was wrong with vehicle. Problem continued and began vibrating badly and pulling toward left (unable to brake). Returned vehicle several times before they replaced "steering sensor" $650.00. Two months later began to lose power immediately after start up, dealer replaced battery. While driving vehicle home problem began again. Displayed low battery, then multiple warning lights for service (ABS, tracking, airbag ect...). Returned vehicle to dealer and they are currently replacing alternator. I have no confidence that this is the real problem based on what I have read on-line regarding this same issue. I also have same leakage issues from both coolant and oil sources that I have read on-line. Dealer continues to tell me to replace both gaskets and thermostat. These again are common issues that are posted consistently on-line by consumers. These are seriously dangerous failures based on people's personal safety. Gm must step up and honor these safety issues by recalling these items. Inability to control vehicle due to tracking system engaging and not able to brake, vehicle losing power and stalling while driving 50 miles an hour, and lastly fire hazard due to leaking plastic valve cover gaskets.
Tl*the contact owns a 2003 cadillac cts. The contact stated that while driving 65 MPH the vehicle stalled and none of the warning lights illuminated. The contact was able to restart the vehicle within twenty minutes. The mechanic stated that the fuel pump caused the failure to occur and it was replaced. During a test drive, the vehicle stalled. The dealer informed the contact that the failure was caused by the anti-theft and on -star features that interfered with the starter and the fuel injection system. The vehicle will be towed to the dealer for additional diagnostic testing. The manufacturer was contacted and there was no favorable response from the representative. The failure and current mileages were 130,000.
Purchased 2003 cts used in 2007 with 54,000 miles. At 60,000 miles, the serpentine belt broke and destroyed engine in the middle of rush hour traffic. 30 days later coil went out and had to be towed again. Approximately 30 days after that the other coil went out and again vehicle was towed to the dealer for repairs. Currently the car is sitting in my driveway and will not start. Took to repair shop close to my house and they said the electrical system is too messed up to run a diagnostic on it. Prior to the vehicle dying in the driveway, the engine shut down in the middle of the road on two separate occasions. I lost steering and had to push it off the road. It is a dangerous and unreliable vehicle and should not be on the road. I contacted cadillac but received no response. The car currently has only 74000 miles on it with a total of maybe 20000 added in three years of ownership mostly due to the car needing constant repairs. I cannot afford to make the payments and pay for repairs both at the same time. I do not trust the safety of this vehicle.
2003 cadillac cts - the backup light assembly came off in car wash... Dealerships are well aware of problem but say their hands are tied because of gm. They said the reason was because the supplier to cadillac used an incorrect epoxy to build the part. Gm knows about the issue but will do nothing. Part is over $550 to replace!! One search on internet brings up hundreds of complaints for same issue. This is ridiculous. I called cadillac and they said they would call if a recall was issued, but they can do nothing more.
Tl*the contact owns a 2003 cadillac cts. The contact stated that the vehicle displayed multiple failures over the last couple of months. The vehicle would shut off without warning. While driving 50 MPH, the vehicle shut off. The contact was able to safely maneuver the vehicle to the side of the road. He attempted to restart the vehicle, but was unsuccessful. The contact heard a ticking noise coming from the engine during this time and was unable to remove the keys from the ignition. The vehicle was towed to the dealer and they stated that the battery needed to be replaced. The battery was replaced at the cost of $106. While driving home after the repair, the failure recurred. The vehicle was towed to the dealer and they determined that the a sensor failed. The vehicle is currently at the repair shop. The contact is in the process of notifying the manufacturer. The failure mileage was 34,000 and current mileage was 36,300.

Tl*the contact owns a 2003 cadillac cts (the contact was not sure if model was correct). While driving 25 MPH, the vehicle stalled. He pulled over and was able to restart the vehicle. The dealer stated that there was a problem with the computer, which caused the vehicle to stall. The dealer replaced the computer. The failure mileage was 29,000 and the current mileage was 29,500.

I am and have been experiencing numerous failures with my vehicle. I have contacted gm numerous times beginning approximately a few months after I purchased the vehicle to inform them that the vehicle is defective, only to be told my vehicle is out of warranty, so they refuse to fix it or give my one that is not defective. My vehicle is still defective to this date.
When driving at varying speeds the stability system comes on, disengaging the cruise control if on, and jerking the vehicle to the left. Took the vehicle to dealer for repair, but situation not resolved. The stability system engaged message comes on at an average of every 2 minutes.
The consumer experienced an electrical defect. Headlights, dashboard, and other illumination components worked intermittently. Also, battery had to be replaced. *ak
(1) flickering display lights; buzzing when turn signal engaged; battery died after 30,000 mile maintenance; eight [8] consecutive times of "engine hot--AC turned off" on dic--last time with check engine light on display.
2002 cadallic ctc has not truck key lock. Adverse conditions occur when the battery fails as all, and I mean all systems shut down. One cannot get into the trunk,use the phone, or even get the keys out of the ignition. But, not having a key lock for the truck is dangerous and unsafe.
Low coolant message three times in my cadillac cts dic. Dealer found nothing wrong, but added antifreeze every time. Antifreeze under the car took to dealer, antifreeze leaking from oil cooler plate. Car would not start even after a jump. Needed new ignition relay and battery.
Vehicle was at a complete stop with foot on brakes, and it accelerated at a high speed.*akconsumer had stopped with foot on the brakes. The vehicle speeded up and consumer had to cut the vehicle off to stop. The vehicle was taken to the dealer and they found nothing wrong. The vehicle is also experiencing electrical problems.
