Cadillac original battery warranty is 4 years or 50,000 miles.
The 6 year pro-rated warranty marked on the top is only valid for purchased batteries; originally installed batteries or batteries installed under warranty still end their warranty at 4y/50k.
SOURCE: I have a cadillac 2002 dhs. It has an idling problem!
You MUST determine ("Due to Check Eng. Light") What the Code / Codes are stored in Computer , as they May Lead us DIRECTLY to the Problem.
Having Said that and with & In my Experience, the Throttle Bodies, AND the EGR Valves Get "CARBONE FILTH " Badly and Block Passages that Are in the "IDLE" Circuit of Throttle Body
side, and In the EGR Valve side of things it causes VACUUM LEAKS @ EGR Valve, This Requires physically Removal of and the Cleaning of these parts by hand. Also the IAC> Idle Air Control Solinoid Can Cause this too Or a Mix of All 3, BUT >>>>>>>>>>>>>>
First thing is I need to know Why Check Engine Light is on that is Determine What Codes Exist On Compter P L E A S E RESPOND BACK TO ME WITH This Information and we can go on from here. I Truely Hope I Can Be of Good Help to you. Waiting for Your RESPONSE.
