    MAY 9, 2024 SO I had to go back to Diamond bc my POS 2018 Encore has a recall for the Turbo and a separate recall for the purge valve. The check engine light came on and i guess enough people complained about this crappy engine GM decided to repair it for free. Diamond fixed the problem at no cost, However, I started smelling something coming from the engine compartment after a few days. Then the check engine light came on. So I took it back, and they told me the check engine light was bc of an O2 sensor and the smell was a leaking turbo oil line. Ready for this, They wanted ****** to replace this line. And an additional ****** to replace the O2 sensor. It gets better, they suggested I replace my spark plugs, ****** which was done 6000 miles ago LOL, maybe they go by miles, but either check one, or have a conversation. I also asked about the transmission flush ******, but they wouldn't apply my "Diagnostic fee " towards that purchase. I took my car out of there and went to *******. Ready for this. The oil line for the turbo was hand tight, gee, wonder how that happened? ( Recall repair, maybe somebody tampered, or "checked it") So they tightened it , All fixed, charged me *****, I gave the guy a tip for being so gracious. As for the O2 sensor, miraculously, NOT throwing a code now, WTF Diamond, you are a bunch of scammers and I am calling GM. That's the last time you get Any money from me.JUNE 2023 Be very careful before you sign on the dotted line. The free oil change and battery for life protection is VOID if you go anywhere else for anything for your car. I mean anything, wiper blades, tires, light bulb etc. I understand they need to make some money, but the last time I was there getting service, they charged me 90 dollars to change my cabin air filter and 65 to change the engine air filter LABOR only another 30+45 on top (it's almost criminal) . oh, after examining the bill, there was an additional 1/2 hour of labor, so after I called them o y
