2023 Cadillac Escalade ESV: check engine light

Filed Oct 26, 2026 · Electrical, Engine · FL

Since May 24, 2026, my 2023 Cadillac Escalade ESV has repeatedly experienced reduced engine power, check-engine warnings, multiple dashboard alerts and loss of propulsion. During one incident, the motor stopped responding, the vehicle lost power and came to a complete stop in the middle of a public roadway. This exposed me and surrounding motorists to a serious collision risk. Whether the shutdown resulted from an internal engine failure or an electrical/control-system malfunction remains UNKNOWN. OnStar documented recurring warnings and fault codes, including engine/transmission communication faults. The same condition returned after multiple dealership visits and repair attempts, including module resets/reprogramming. At times the check-engine light was no longer illuminated upon arrival, but the dangerous symptoms and OnStar reports had already occurred. An authorized Cadillac dealership blamed alleged aftermarket alarm/tracking equipment and proposed charging approximately $1,900 to remove it. I paid $250 for an independent inspection, which found no such aftermarket equipment and identified the questioned component as a genuine GM part. This incorrect diagnosis delayed meaningful investigation. GM escalated the matter to a specialized field engineer at Braman Cadillac. I was informed that the senior engineer could not identify the cause and requested another engineer. The promised follow-up inspection was still pending nearly three weeks later. Despite repeated visits and manufacturer involvement, no confirmed root cause or permanent repair has been provided. GM did not arrange towing for the latest return. I drove the malfunctioning vehicle in the emergency lane everyt time because it could not be trusted to maintain normal operation. The vehicle remains at the dealership and is available for inspection. I request investigation of the recurring shutdown/loss-of-propulsion safety defect and the unsuccessful diagnostic and repair history.

About 11pm Driving 70 on freeway started feeling pull back and then started to hear a knock noise. So turned down the music and the knock noise was getting louder as I was driving so I went to the right lane as I went to the right lane I felt like the car was pulling back and slowing down even as I accelerated… knock got even louder and I decided to exit the freeway early instead of getting to my destination. As I exited the freeway the entire car shut down lights flickered check engine went on and low oil pressure flickered once but then turned off. I couldn’t get it in park couldn’t get the car to turn over. I was able to get out of the middle of the intersection turning off the freeway and pulled gas station called AAA. I’ve had no prior problems or warning lamps before this problem happened with the vehicle. I have videos of the whole incident that will not let me download on bottom of page. “2023 Escalade ESV, VIN [XXX]. Towed to Cadillac of Laguna Niguel.

In August of 2025 my escalade went t the dealership to perform the engine recall test. It passed the test and the oil change fix was completed. However, within weeks or so the engine began to experience some issues. It was taken back to the dealership and a full engine replacement was performed. Fast forward to the beginning of August 2026. The new engine is experience the same symptoms as before. Flashing engine light, rough idle, loss of power, and excessive gas consumption, knocking, etc. I took the car to the dealership and this is the service advisors message to me about the car: "Cylinders one and six are causing the misfires, he sent some information to our technical assistance center because the cylinders walls do not show a lot of damages but, like I said before it was low in oil with no present oil leaks. He has to capture some freeze frame data for technical assistance and send in so it has to be driven some more. They want it driven over some miles. They will determine if we replace the engine or not, I may not have an update from them until Monday. They do not work on Saturdays and Josh your technician has to perform all of the test they sent over. A lot of the extra testing has come from this possibly being the second engine that could go in the vehicle. The car remained for about 2 weeks and gm refuses to pay for a new engine until because there isnt enough data. Meanwhile I am stuck driving a car that can seize up and leave me at any time. They also refused to buy back or help me into another vehicle without coming all out of pocket on my end

On [XXX], while driving my 2023 Cadillac Escalade ESV from the Salt Lake City area toward Las Vegas, the vehicle developed a serious loss-of-power condition in Utah. I contacted OnStar, exited the highway, and waited at a gas station. OnStar arranged towing to a Cadillac dealership. GM records document the tow at approximately 56,644 miles. At the dealership, I reported the loss of power. After initially being told they were too busy, I waited about 10 minutes and was then told the vehicle was ready. After returning to the highway, the vehicle suddenly lost power again at approximately 70 mph. Pressing the accelerator did not produce normal acceleration, creating a serious risk of a highway collision. I immediately returned to the dealership. The dealer then performed another repair. The invoice states the Service Engine Soon light was illuminated, soot level was 255%, and a service regeneration was performed. I was charged $406.16 and was again told the vehicle was ready. After leaving again, the same loss-of-power condition occurred. After safely exiting the highway, I recorded video showing the vehicle at approximately 38 mph with little or no acceleration response and the check-engine light illuminated. I returned to the dealer for a third time. The dealer then kept the vehicle, stated the repair was covered under warranty, and provided a rental. The vehicle has remained under repair since July 21. I have not received a clear explanation of the root cause or complete repair details. I have videos, towing records, repair documents, photos, and GM correspondence. I am concerned this repeated sudden loss of propulsion at highway speed could cause a serious crash. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2023 Cadillac Escalade esv has been at the dealership countless times over the last 2 years with strange engine sounds, acceleration issues, 4 wheel drive would top working and I couldn't make turns without a grinding sound coming from under the hood, check engine light (with no issues seen/heard). The engine recall was "passed" in October even after our concern with the engine sounds and strange things occurring while driving. Last week my wife was driving on a 4 lane 70mph freeway with our son in the car at night and the car said "press start again" and then started slowing down. She could not brake or accelerate. Luckily there was nobody to the right and was able to make just across the line to the side of the road when my car just came to a stop and everything turned off. So she sat there with my son in the dark for an hour barely off the side of the the road before a tow truck driver came but he couldn't even get the car into neutral to get it up onto the truck. My escalade is now at Cadillac of south Charlotte in North Carolina waiting for a new engine. We are scared to drive it even after the "fix" hearing that it can happen again with my kids in the car. GM needs to be forced to buy back or lemon these cars before someone gets seriously injured or worse.

On December 19, 2023, when pulling out of a parking lot onto the street, pressing the gas vehicle jerked and would not accelerate. No lights on dash. Drove less than 1 minute and turned down a side street, to get out of traffic while going slow/no power. Stopped at stop sign, went thru intersection. Went to next intersection, at stop sign, vehicle shut off, in the middle of traffic. Still no dash lights. Vehicle would not start. Turned on hazard lights. While waiting for tow truck, tried cranking several times. After about 3 hours check engine light came on, with a red light to the right of check engine light. At the same time as the check engine, I received an alert via the Cadillac App 12V error, please crank vehicle. Each crank try, dashboard would light up/cycle but vehicle never started once it shut off. Tow truck driver thought it may be battery. Tried getting vehicle to crank. No joy. Towed to dealership which replaced Transmission in August 2025, 3395 miles ago to find my engine seized up after recall N252494000 PERFORMED, Picoscope test and oil type changed. NOW THIS. Patience is really being tried. Another month without vehicle. Payments are continuing.

In March 2025, my 2023 Cadillac Escalade ESV experienced a sudden engine failure. The engine began running rough, the check engine light turned on, and the vehicle became unsafe to drive. The Cadillac dealer diagnosed the engine with #8 exhaust push rod bent and metal debris in the engine oil. This matches the defect described in GM Recall N252494000 (connecting rod/crankshaft internal engine defect). I paid $10,000 out of pocket for a full engine replacement at Crestview Cadillac before GM mailed the recall notice. I submitted a reimbursement package to GM’s Recall Reimbursement Center by USPS certified mail. USPS Tracking Number: XXX Delivered on 07/17/2025 at 11:02 AM in Detroit, MI 48226 (“Left with Individual”). GM has refused to reimburse me and will not provide a written explanation. Two other Escalade owners with the same engine and similar failures have already received reimbursement from GM. I believe GM is not complying with the recall reimbursement requirements.
