Rip off I don't understand the point of a factory 5yr 100k mile warranty. Dealership tried to charge $1600 for a new radiator. Because it had a crack. The tru I don't understand the point of a factory 5yr 100k mile warranty. Dealership tried to charge $1600 for a new radiator. Because it had a crack. The truck is a 2015 with 42k miles and would not cover it. The radiator is conected to the motor which is power train. Also they said I needed a new lower a arm because the ball joint boot was ripped?? Couldn't they replace just the $50 ball joint? Sounds like they take advantage of people. Had to go into the dealership to talk to anyone bc they wouldn't call me back. More

Quick and pleasant I decided to get my oil changed and tires rotated along with a request to check the transmission for slipping. It was Monday so the it was a busy day I decided to get my oil changed and tires rotated along with a request to check the transmission for slipping. It was Monday so the it was a busy day in the service drive although I was greeted quickly and I chose to wait for the services to be performed. Ray was my advisor and gave me a tip about my sound system I wasn’t aware of. Transmission was fine and my vehicle was ready sooner than expected! Will always use Mark Christopher. More

Alison Transmission repaired efficiently I was recommended by Reynolds GMC Buick dealership in Covina, Ca. because they could not do the repair. My problem I had was with the Alison transmis I was recommended by Reynolds GMC Buick dealership in Covina, Ca. because they could not do the repair. My problem I had was with the Alison transmission. It shifted hard on a down shift between 50-70mph. Reynolds diagnosed that I needed a new transmission or it needs to be rebuilt. After 3 long weeks at Reynolds they did nothing to my transmission but talk. I then drove my truck to Mark Christopher service department in Ontario, Ca. and they repaired my Alison transmission in less than a day. They found two issues: 1. 2 quarts of fluid low 2. An upgrade software from GM that fixed the hard shifts. I totally recommend Mark Christopher for your servicing needs. Thanks a million Juan Fletes! Regards, Mark Galves More
