Comparing two older enthusiast cars: one has lower mileage but thin history, the other has higher mileage with years of invoices and owner notes. Assuming both inspect well, how much value do you put…
A/C gets properly cold on the highway but becomes noticeably warmer at long lights. It cools down again almost immediately once the car is moving. Could this still be a refrigerant issue or does that…
2023 GMC Sierra 1500 AT4, about 78,000 miles. Truck is within published ratings, but with a tall enclosed trailer it gets pushed around in wind more than I expected. Before changing trucks, what woul…
2023 GMC Sierra 1500 AT4, about 37,000 miles. Filled the DEF tank but warning returned sooner than expected. Before blaming the sensor, can old/contaminated fluid or crystallization create this kind…
2023 GMC Sierra 1500 AT4, about 4,800 miles. Front tires look fine from the outside but the inner shoulders are nearly done. Car is lowered a little. I'd rather fix the alignment than just keep buyin…
2023 GMC Sierra 1500 AT4, about 48,000 miles. I saw a recall announcement that includes my model year, but my VIN currently shows no open recall. Is that usually because only a subset is affected, or…
2023 GMC Sierra 1500 AT4, about 62,000 miles. Front PPF did its job but now has a small nick that catches the light. Paint underneath appears fine. Is spot repair realistic or do most installers repl…
After lifting the vehicle, it drives okay but steering feels different and the wheel doesn't return to center as strongly. What alignment/geometry values matter most after a lift rather than just acc…
I am selling privately for the first time. I want serious buyers to drive the car but do not want to be careless with keys, insurance, license info or where we meet. What is a sensible process? Inter…
2023 GMC Sierra 1500 AT4, about 22,000 miles. Car only has 32k miles but the coolant is several years old. Would you change it based on age alone? I'm trying to prioritize maintenance that matters ra…
I want reliable fridge/lights/device power for weekend trips without making the vehicle electrical system unnecessarily complicated. When does a hardwired dual-battery setup beat a portable power sta…
2023 GMC Sierra 1500 AT4, about 54,500 miles. I want reliable fridge/lights/device power for weekend trips without making the vehicle electrical system unnecessarily complicated.
This started as a small annoyance and I finally decided to track it down. News says my model year is involved, but the VIN lookup shows no open recall. Is that usually because only certain build rang…
2020 GMC Yukon Denali, about 74,000 miles. I have brought the car in twice for the same intermittent warning and both visits ended with could-not-reproduce. I have video and timestamps. What is the b…
2023 GMC Sierra 1500 AT4, about 42,000 miles. There is a light buzz from the dash at one narrow RPM range. It disappears above and below that speed. Any good method for locating trim resonance withou…
A windshield was replaced and now there is a whistle around highway speed that did not exist before. Glass looks seated. Any simple way to locate the air leak before taking it back?
There is one front-end clunk over pothole edges and driveway lips, but larger smooth bumps do not reproduce it. How would you isolate end links, strut mounts, control-arm bushings and ball joints? I…
The car is smooth at the same road speed when I lift off, but under moderate acceleration I can feel a vibration through the floor. What would you inspect first to separate axle/driveline issues from…
2023 GMC Sierra 1500 AT4, about 50,500 miles. I have brought the car in twice for the same intermittent warning and both visits ended with could-not-reproduce. I have video and timestamps. What is th…
