May 26 2020 dropped off 2011 Ram Laroma 1500 truck engine light on told needed cam/lifters &;;;;; transmission. My son made arrangements to have engine work done. After discussions & quote my son & Ryan the manager agreed(altho now Ryan back tracking says there was no discussion) my son would purchase cam/lifters since he was going to be charged approx $3000 for same parts my son could purchase for approx $1100. Aamco wanted a 300% markup...ridiculous! After having truck for close to 2mths truck went to tuner to remove mds codes once at tuners the same codes my son took truck into Aamco for came on...& paid Aamco close to $4000 to fix. Truck had to be towed back to Aamco it was there for another 2wks son was told "we" are doing research can't figure out issue. I had enough & called spoke with Ryan myself of course he kept denying sny conversations or other topics that indicated Aamco was a part of problem. Funny tho the next day my son got a call saying cam/lifters were wrong. Blaming him for truck not getting fixed. Truck was towed back to my house the tow truck driver who said he was friends with Ryan said " Ryan immediately started saying the guy brought us the wrong parts". Once again he's covering his back side. We, as consumers, depend on these so called "professionals" to know what they are doing. The time to do research was BEFORE putting parts in NOT afterwards so that makes these people incrediably arrogant or ignorant one of the 2. Let's add my son was told they'd fix it for another approx $1200 just depends on labor. My son is out alot of $$$$ & still has same issues....THIS IS NOT GOOD SERVICE!
