How to handle a mechanic who messed up brake repairs

Bad mechanics often leave safety hazards like air in brake lines or incorrectly installed shocks that cause new noises and loose bolts. When you have to keep returning for the same unverified fix, it destroys your trust and forces you to drive an unsafe car.

I brought 2020 VW Jetta into the dealership I purchased it from for an oil change (free oil changes for life).source ↗

I drove a total of 17 miles away from the dealership, and the low oil pressure light turns on, I hear a knocking sound from the engine, and the error stop start light turns on.source ↗

Popped the hood and the car was bone dry of oil, and there was oil all over the splash guard of my car and all over the car and engine bay.source ↗

Towed it back to the dealership, and they determined the tech installed the wrong oil filter and it failed!source ↗

They are having me speak first with what I would like the resolution to be but I can’t think of any other resolution than a new engine. Who knows what could be damaged internally.source ↗

Our 1995 barn roof started leaking in 2021. Had two roofers for advice—both said the first step was to replace the screws. We went with a highly-rated local roofer and they replaced the screws in 10/2024 for $4K. Leaks persisted.source ↗

The guy who checked the roof showed me the photos you see—there’s an empty hole next to every screw over the entire roof (27 squares.) He said that this wasn’t normal.source ↗

I contacted the original roofer. His exact response was—“all our crew attempted to do was replace the old screws with new ones. Is this a situation where our company is trying to be blamed for a very old roof leaking after a repair was attempted at fixing it?”source ↗

2 days after, I notice a yellow marking on my tire around a bulge.source ↗

If they would have told me about it when they called when it was ready for pickup or when I got there. I would have just decided to get a new tire or drive 2 blocks down the street to the tire shop the same day on my own acknowledging the risk.source ↗

Today I was told my calipers were wound up to retract the piston(is that the right term) rather than put in service mode to electronically retract the piston(not sure I’m using the right terms) when looking at the calipers the rubber that goes over the piston is all chewed up. There’s junk and metal flakes all in the piston jamming it up. I’m being told I need new calipers now because of all of this and it’s expensive.source ↗

Would you just pay the new shop to do the work or should I mention to the high school friend that one shop is saying the brake job was done wrong and parts now have to be replaced.source ↗

I was driving normally when I suddenly heard a massive grinding noise from the right rear wheel, and the brakes essentially locked up.source ↗

The roadside technician removed the wheel and found that the lower guide pin bolt on the brake caliper was missing (either fell out or sheared off).source ↗

However, I had the car checked in a new independent mechanic to fix the recent breakdown. The new mechanic showed me the old pads and discs: the pads were completely worn down to the bare metal backing plate, and the brake disc was heavily scored and completely destroyed.source ↗

He explicitly stated that there is absolutely no way these pads and discs were changed or properly serviced 40 days ago, given the catastrophic level of wear.source ↗

I dont trust him because he did this job and shes now going back for the 3rd time.source ↗

He first left air in the break lines he said by mistake and now hes claiming shocks he installed are rubbing on the top peice of steel you see in the photo cause the bolt came loose in the trunk he saidsource ↗

When I first got it a full tank got me around 400 miles, but now it's about half that, and it genuinely feels like on the distance to empty screen whenever I drive a mile it drops 2 miles.source ↗

I've taken this vehicle to the dealership and I'm driving a rental for work. It's been a week and so I checked with the dealership and they said they are throwing spark plugs and ignition coils in.source ↗

I call b******* and think that they have no idea what they're doing.source ↗

If this were my personal car I would be livid. It's at the dealership because they are supposed to be familiar with these issues. Otherwise I could've just gone to express oil. Or pep boys. Or meineke.source ↗

After they looked at it, they said it was the rear differential that was acting up. He quoted me two prices ~$1700 for parts that have a 75% of fixing the problem or $5100 for a whole new rear differential that would definitely fix it. I didn’t want to gamble, so I opted for the higher price.source ↗

I picked it up after a few days, 15 minutes into driving it I had the exact same issue.source ↗

He said it was probably the tires being worn down. Paid $500 for new tires. The issue still wasn’t fixed.source ↗

I feel like I was kind of being taken advantage of.source ↗

Don’t think it’s covered it’s cowboy garage I gave the car in for inspection test. He’s not owing up regardless I gave him the car and keys so it should be his responsibilitysource ↗

Mechanic said they had to cut in order to get the bolts out that were spinning in order to change the alternator and replace the belts.source ↗

Used zip ties to re secure one of the motor mounts and welded another to the frame.source ↗

Also did it without telling me or my consent.source ↗

I drove the car 20 minutes had gas leaking from a gas line and stopped at a shop and that’s how I found out.source ↗

I recently got all 4 brake pads and rotors replaced. The service advisor was somewhat very hesitant to replace the rotors and he said only brake pads needs replacement.source ↗

In the service record I see a note that my rotors were resurfaced but I was charged for the rotors.source ↗

Advisor says it’s replaced but wanted a second opinion from folks who are more knowledgeable.source ↗

I am getting suspicious because the service team called for a feedback after a week and when I asked them they said the rotors were resurfaced.source ↗
