https://www.hotcars.com/2023-cadillac-lyriq-ev-10-reasons-why-were-excited/ When Cadillac first introduced the Lyriq in 2020, it set a target date of late 2022 for the first deliveries. However, things have progressed quite smoothly for the EV since then and it will now launch 9 months ahead of schedule. US buyers can expect to start taking deliveries in the first quarter of 2022 for the 2023 model year.

Got a check engine light with a couple of codes. Took it in to dealer, and they found the wiring hardness had a defect. They are covering it under the powertrain warranty. Apparently they do see this now and then and it is just situational -- it can mean low transmission fluid, bad sensor, bad harness, etc.

Resto mod for $140K? Sort of a Series 62-V. I do like the look from that era. https://www.hemmings.com/classifieds/cars-for-sale/cadillac/62/2429429.html?refer=saturday&utm_source=saturday&utm_medium=email&utm_campaign=2021-07-24

Info from the Bars site: What if I don’t have a radiator cap? If vehicle does not have a regular radiator cap, remove top hose where it attached to radiator and insert tablets in hose and then reinstall hose. Use extreme caution; the cooling system is under pressure and is not safe to open when hot. If the hose is not properly disconnected and reconnected then the cooling system will not be able to maintain pressure, and engine damage can occur. For this application, the tablets are easier to apply than the liquid. But I believe the mfr's instructions are to remove the upper hose, use a funnel with a tube attached, or other similar method, to pour the stop leak into the radiator, or into the hose connection, then reconnect the hose.

owner notes: Oh I forgot to include some new information I have. The volt reference code is the OTHER side now, so no longer B circuit anymore but A circuit. Not sure how that happened after the new ecu or what it suggests

Thank you for the detailed response, and welcome to Texas & CaddyInfo. I appreciate this may be confusing, but although yes I drive a 2016 ATS-V, this is a "mailbag" post which is to say someone emailed me directly instead of posting it in the forum. That person has an STS-V, which is the vehicle with the issue; my ATS-V is fine. I think your logic still applies for a good approach to diagnosis & I have also forwarded to vehicle owner. Currently he is dealing with a muscle car shop, not a Cadillac dealer, and they were smoke testing the intake to try to establish why it is running lean DTC p0171 p0174 and the 5 volt reference

Sorry things seem to be stacking up. You are more than welcome to vent here.

No no longer p2135, just p0171 p0174 and the 5 volt reference

Owner update: Spoke too soon. Car went into reduced engine power again, giving 5 volt reference on the other side now

Which two door would you pick for $21K? XLR, CTS, ATS Through recent research, I’ve noticed something very interesting: In The Current Year, the XLR, CTS, ATS, and ELR (that’s every two-door model Cadillac has produced since 2004) all command the same money on the used market. Their pricing is aligned at around $21,000 to $24,000 (excluding V variants). That’s fairly unusual given their different ages, power, and overall missions. Today we look at the three most traditional options of those four (not in V guise), and leave out the ELR because it sucked. https://www.thetruthaboutcars.com/2021/07/buy-drive-burn-three-two-door-cadillacs-one-price-point/

In the summer of 1952, 41-year-old Henry Opitek showed up at Harper University Hospital in Detroit complaining of shortness of breath. If ever there was a glass-half-full, glass-half-empty story, Opitek’s is it. Turned out, he had a major heart issue. At the same time, he was in luck. Doctors at Harper had a nifty device they wanted to try out. Opitek was about to become the first human being to be kept alive using a mechanical heart. The thing was larger than today’s microwave ovens, and—not at all coincidentally—it resembled a V-12 engine. https://www.roadandtrack.com/car-culture/a36754269/how-general-motors-modeled-the-first-mechanical-heart-after-a-cadillac-v-12/

Owner Update: So knock on wood. What I was suspecting from the beginning of this ordeal. The ECM. They swapped in a new ecm from the factory and is not pulling any codes after a 30 mile test drive. I told the shop to put at least 100 miles on it before returning to me. Will let you know the verdict tomorrow.

Sorry to hear; sounds like you have a short shopping list though

In our time with the 2021 Cadillac CT5-V, at least a half-dozen people asked us how the car drives. When we told them it was one of the more fun cars we'd driven in a while, half of them rolled their eyes—and the half that didn't still hardly believed it. But our impression was backed up when road test editor Chris Walton came back from the handling track yelling out the window, "I wasn't expecting it to be this fun to drive!" That's from someone who beats on more than 200 cars a year. https://www.motortrend.com/cars/cadillac/ct5/2022/2021-cadillac-ct5-v-sport-sedan-first-test-review/
