    Recently I've been having to use the manual release to open the door on my car. Is this a major problem? No, but it sure is annoying. If you know the 2013 CTS coupe you know it has a button to open the door instead of a normal door handle. This feature is awesome, however within the last month...

Fast Forward: New Alternator, Relay, Starter; it did it again! Do you recommend a 2nd Battery or a small amp to regulate how much the system drains in motion or...

    Hello! I need some advice. Took my 2012 CTS in for routine oil change and they said my right rear axle seal was leaking. Quoted 450. The part is 16.00. I had a different mechanic look at it and said it was "slinging grease" and that it's the whole axle. Quoted me 500. Called the dealership and...

    Hey everyone, I’m looking for a way to replace the USB port in a 2009 Cadillac CTS. I can provide a VIN directly to parts dealers/Cadillac Service rep. We used to plug in and the entertainment system recognize a USB connection and play whatever audio with title info on screen. The issue now...

    Hi there. I have a 2009 CTS 3.6L DI and I recently installed a K&N Typhoon CAI on it. It sounds amazing! Buuuut, it has my car acting wonky. Service Traction Control came on about 12 miles into the test drive. Then, another 45 miles later, my check engine light came on. Sounded like maybe my ECM...

    Hello, I have a 2014 CTS and the interior cabin lights immediately turn off when coming on. Even when turning on the switch for the interior lights it still turns off after a second or so, so I’m assuming it’s not the day/night sensor. I’m an electrical engineer and have checked the basics. Any...

    Hello, this is a guide on how I replaced the ECM on my '05 CTS. In total it only took me 30 mins. If you haven't bought one yet stay away from Flagship One and All Computer Resources. Step 1: Make sure you disconnect the negative battery cable before starting, the bolt size is 8mm/5/16" Step...

    My heater core is leaking and I’m trying to avoid replacing it entirely if possible. Someone mentioned using two tubes of Alumaseal would fix the problem but I wanted to ask around before I do something that damages my car permanently. Has anybody had success with radiator sealant? And if so...
