I think Yerena's scammed me. My Trailblazer 107k, never had a major problem, went in for a standard oil change. I drove half a block from their shop and threw a rod. They hooked up equipment to diagnose the noise and said it was my timing belt flapping...lol, right. Didn't offer to fix it, just said it wasn't a rod. Took it to my step dad's mechanic who said it definitely threw a rod. I wouldn't know if they forgot to put oil in the first time, because they took it back into the shop, probably to put oil in to cover their butts. My Charger went in for AC servicing. They took it around the back of the shop. Suddenly it developed a problem & wouldn't start. It magically started before AAA came to have it serviced somewhere else.They tried to blame it on my shifter being out of place, because the car had a recall years earlier for the plastic shift interlock latch, which when broke, it would lock people's cars in park. However, my interlock latch already broke years prior and I got a new metal one for the car. The problem was NOT my interlock latch causing my shifter to be out of place. Funny how it never had problems starting before I went to Yerena's, nor have I had any problems over a year later. Same with the Trailblazer. Never a major problem before Yerena's, go in for an oil change, drive 1/2 block from their shop and it throws a rod?I am sad to say that I feel Yerena's tried to scam me with the Charger, and they did not provide reliable service on my Trailblazer, then lied to cover their butts. Why did I bring my Charger in after the incident with the Trailblazer? Because I wasn't sure who to believe. My step dad's mechanic would have made a heap repairing my engine. Needless to say, I don't trust mechanics. The Charger was scheduled to come in just days after the Trailblazer. I got a third opinion weeks later who confirmed it threw a rod.
