I am officially the biggest loser when it comes to cars. Bought a new 2018 Max Steel SXT on January 27. Traded my 2014 SE which a different dealer had poisoned by putting the wrong coolant in. Car was puking dissolved aluminum into the coolant. Maybe could have fought them, but decided to cut my losses. '14 had 92k on it. Anyways, on January 30, car popped a CEL at about 130 miles. P06DE. "Engine Oil Pressure Control Circuit Stuck On" Car to dealer on Jan 31. 80 miles from my house since I'm not going back to the other one. Tech decided bad oil pressure sensor. Went back Feb 2. Replaced oil pressure sensor. Oil pressure still high - 55psi idle - compared to '14, and to another '18 sitting in lot - both mid 20's at idle after warm up. Went home. Later that night went to WalMart. Ding... CEL. Read code when I got home. Same. Off to dealer on Feb. 5. Tech opened Star case. Answer.... Bad oil pump. So I have a car where they have to do major surgery for a problem that was basically out of the gate. I got a loaner - a minivan - and went home. Fast forward to today Feb 9. Called and "should be ready in an hour" at around 11:00. Drove out. 1:30, still putting together. afternoon goes by, and he's ready to test. Comes out and tells me he has to replace the radiator. Apparently poked a hole in it. More time goes by. He test drives it, and says all is well - except for the CEL when I got in it. Don't remember code, but it was Intake air temp open. Ooops... forgot connector. So I take off and get to the highway. 70 mph highway, and car does a lurch, and a crapload of lights come on. ABS, ESC, CEL, etc. Car grinds down in speed. I pulled over, and tried to take off. Nope. Barely accelerates. Eventually get up to about 40mph. Didn't want to shut it off, but had to. Limp home mode I guess they call it. Start cycle it, and it drives. Meanwhile I'm calling dealer to tell them they better be there. Get back, and codes are read. Crank / cam position sensor (not sure which). Tech says it's picky, and he had to pull sensors when replacing oil pump. Says probably needed to reseat. He does all that, and I leave. All seems OK. Then I stop at Mcdonalds. When I restart car, engine clanks like a diesel for a couple seconds. Goes away, but I still hear ticking. Step on gas, and ticking goes away. I continue home. Car drives OK. So, new issue: Every time car started, get a loud rattle - like maybe what's been described if the oil drains out of filter. Not sure what the hell to do now. Attempt at recording it. Two starts. First it's pretty obvious. Second, not as bad, though the ticking is there after starting. Be aware, that it was raining when I did this, so the sharp continuous ticks are irrelevant. It's rain. Maybe try to get another better recording tomorrow morning.
