I have owned several brands
I have owned several brands of vehicles and have never had a positive experience any dealer service department.
BMW:
1) told dealer to check belts and hoses while having coolant changed. Two days later lower coolant hose explodes leading to warped head and gasket failure
2) Driver's wiper arm linkage snaps during monsoon. Can't see anything.
I tell the "Service Manager" that I left the wipers running while warming up car and they got stuck in ice and that probably bent something. Check motor and entire assembly. They replaced a $10.00 part plus $150 labor. 1 week later linkage snaps during another monsoon. I go back and dealer quotes same repair. I tell them that something is bent that is causing stress on the part that is breaking. They tell me that they are just trying to save me money. How about saving my life by knowing how to repair a kind of important safety feature of any car. They only fixed the real issue after I screamed at them to replace the whole bleeping assemply or sell me the part and i'll bleeping do it myself.
Audi:
Quoted $2500 to fix a pin hole in exaust. Went to local shop and they welded in a flex pipe. $150.00 repair. Drove anther 50 K mikes, no issues.
Ford:
Sued Ford because my wife's Fusion had transmission issues.
Dealer continually denied there was any problem and said the the tranmission was slamming 2nd and 3rd gears because it had to learn my wife's driving habits. I finally demanded that I go on a test drive with the shops transmission specialist, and after 20 miles and countless gear slamming issues, he admitted that there was a problem.
Dealer made 2 attemps to fix with no improvement. I Googled the issue and found the cause. Ford actually had a TSB for the repair. I printed out the TSB and gave it to the service manager when I went in for the 3rd attempt. The ignored it and tried a different repair. Needless to say it did not work.
One day my wife and I were shopping for an new car when the transmission suddenly went into limp mode just as we were crossing a busy highway. We were nearly T-boned as a result. We had the car towed to a different dealer and they towed it back to the original dealer. Somehow they could not find any issues with that death trap and told us to come pick it up.
Mazda:
Cross threaded oil plug. I fould leaking oil before and damage occurred.
Mechanic was also lazy and only attached the skid plate with a few bolts.
Dealer also did tire rotation and overtorqued lugnuts making it impossible to change a flat tire. Called AAA and they towed the car to a tire shop. Because the shops were closed I had to hotwire a hotel. That screwed up my vacation.
Sorry for the rant, but why should I have to tell a so called expert how to fix something. And pay $$$$?
I now do most simple repairs myself (oil changes, brakes, shocks) I also re-tourqe lugnuts any time a shop removes a wheel. I also found a really good local mechanic. My nightmares are gone and I have saved a huge amount of time and money.
