I purchased a 2011 Jeep Grand Cherokee from a private seller in September 2016. March 2017, the check engine light came on, so I brought it in for service. Turns out it had a cracked cylinder head (which was covered under an extended recall). I told them that while the engine was torn apart, they should replace the spark plugs, since I was unsure if they had ever been replaced. When I arrived to pick up my vehicle, they told me the cost of replacing the spark plugs was somewhere around 450 dollars. I was blown away, so I asked to see the invoice. The invoice they showed me showed me being billed for parts and labor for replacing 16 spark plugs. I don't have a Hemi in my Jeep, so I don't have 16 plugs. I asked them how it was possible for them to replace 16 spark plugs in my vehicle, and they told me that it's because I have a Hemi. I stared at him for a second and told him that is not true, I have a V6. He called his manager over, and I explained how they were trying to screw me on parts/labor. He corrected the bill, but it still left a sour taste in my mouth.
Fast forward to today. I brought my Jeep in for an oil change. As the vehicle was finishing up, the service writer came to try to up sell me some "recommended" services. He started by trying to get me to agree to a 110 dollar brake fluid flush, since, in his words, "your brake fluid is very dark and needs to be replaced". I let him finish his BS he was trying to sell me before I told him that the brakes were just done a month ago, including the brake fluid. In fact, there was a brake fluid leak, so I was constantly having to top off the fluid until I got it fixed, so it's kinda hard for my fluid to be "old and dirty". He then backpedaled and said that it was just recommended based on the mileage of the vehicle. Strange how just a second prior, he was claiming my brake fluid was old and dirty.
I will be taking my Jeep to the GM dealership next door from now on, I don't care if they are not Chrysler based.
