2016 Cadillac Escalade: misfire or rough idle

Filed Feb 27, 2026 · Engine, Suspension · FL

Suspension failed at 50,000 miles. At 56,000 miles one of the valve components inside the engine (a lifter) has collapsed. This part controls the opening of the engine valve, and because it is no longer moving, that cylinder cannot build compression and is causing the misfire. This is an internal mechanical failure inside the engine and cannot be caused by body work, fuel quality, or anything external.

The engine just stopped working mid traffics shifted to neutral automatically- almost causing a serious accident on a busy interstate . Brought to the mechanic, readings stated misfiring cylinders as engine seized and slipped. Tried fixing issue for $8300.00. Then after trying to fix it with no luck, cylinder 5 and seven were stuck and could not be repaired. Cost of labor to out engine back together was $4600.00 plus $400 to tow it to a dealer. Not only life threatening but also wallet draining with no warning. Will never buy a Cadillac again. This is a serious threat for those driving in it and for those who come across it when something happens.

67 days & 1230 miles after purchasing, just after starting and merging into heavy, fast moving city traffic, the check engine light & several others come on. Then on star text and email diagnostic alert received: "service the engine and transmission in your vehicle immediately". The engine was acting sluggish, rough, jolting, no acceleration, max speed barely 30pmh, A/C stops working. On star diagnostic report (monthly email report) at 1200 miles was perfect, 40 minutes prior. Dealer service diagnosed cylinder #2 misfires, component testing on the threshold of being shorted. Replaced #2 fuel injector. Diagnostic codes avail. If needed. Vehicle is brand new! Concerned about serious future engine problems with no warning and/or possibility vehicle is a lemon.
