Big John’s Performance

Big John’s continues to be my go-​to place for my auto repairs. The guys are extremely knowledgable and always get the work done quickly. And most importantly, I trust them completely. I won’t take my cars anywhere else.

Extremely unhappy with Big Johns. I live in Washington state and was passing through town on my way out to Texas for a job. On the way from Seattle down, a seal where my driveshaft meets the rear differential gave out and was spinning out oil under the whole underside of my hummer. I called up big johns (only place open on Saturday) and asked if they would be able to replace this seal. I was very very specific which seal considering my hummer is 4wd and there are two driveshafts and two differentials (front and rear). To properly replace this seal, the differential piñón nut has to be torqued accordingly which is why I didn’t do it myself. They let my know that they had the resources and tools to complete this task but today being 1pm on a Saturday, they wouldn’t be able to finish it. They let me know however that they would put it on the rack to take a look and get me a price by the end of the day. I had my phone by my side the rest of the day but no phone call. Monday morning I called them at 8am to check up (a.k.a I need my car guys). They told me they would get it up on the rack (same thing they said Saturday) and get me an estimate. 11:30 AM i called again to see what’s going on, getting kind of frustrated at this point. They again told me they are about to put it up on the rack and midway through his sentence one of the guys cuts him off and tells him the estimate created for my car. It was reasonably priced and AGAIN I explained which seal it was and how vital it was to me getting back on the road again. They said it would only be an hour or so (to be completed 12:30pm). 1:30 I showed up thinking all I had to do was sign the papers and had the piece of plastic over to pay. I stood there for 35ish mins before the guys upfront ended their conversation and asked if I had been helped yet. I let them know I’m the owner of the hummer and they said it was still on the rack and should be only 10 or 20 more minutes… 4 HOURS PASSED. I REPEAT FOUR HOURS. It was kinda hysterical at that point because I heard them tell the same information to people who brought their cars in for a simple tire nail patch. Each person ended up staying there for hours… I do not understand how this place keeps its business. 5:30 I finally get word that my hummer is finished. They apologized and said that a car was blocking my hummer and the parts for that car arrived late so they could not move it out of the way of my hummer. I paid early to get it out of the way since I was anxious to leave. Walking out the door, the technician drives by in my hummer taking it around the block (not even sure if this is legal) he came back and said everything was good. I went on the ground under my rear axle, showing him all the oil that had spewed out on my drive down, he looked at me kind of weird and said «yeah you should get that fixed». Confused, I asked him what he meant. He said that he noticed this leak as he was changing the seal. After going back and forth I realized HE DID THE WRONG SEAL. THE WRONG SEAL WHICH I THOROUGHLY EXPLAINED more than twice. He gave me the sheet of paper explained the repair requested and apparently whoever I spoke to about the issue wrote down a very simplistic description on the work order «seal from driveshaft to differential». Not once did I describe the problem this simply. I was very very clear that it was the piñón seal where the drive shaft meets the rear differential. The mechanic changed the front axle seal. A seal I could’ve replaced in a driveway. I am extremely unsatisfied with this business and I would encourage people to go else where. At this point I’m concerned because I’ve just wasted a bunch of time at big johns, and the problem is still occurring. The leak was so bad, I would not make it to Texas without constantly refilling my differential fluid or without completely blowing a differential.
First thing Tuesday morning, I found a jeep shop in Santa Clarita and explained my story to them. They were just as amazed as I was with my experience at big johns and put my hummer on the rack in under 5 minutes. I was expecting to be there for hours. The technician changed the seal out in under 30 minutes and I was on my way.
Listen to these bad reviews. I looked past the negative reviews and boy was I wrong. Never again

This place is the best!!! Thank you to Rob, Nathen and especially Little John. They went above and beyond taking care of my needs and wants. This establishment has a great selection of products and services. The customer service is unmatched in Santa Clarita Valley. I am a returning customer and will continue giving my business to them. Again, thank you Little John for your patience and outstanding service.

Poor customer service! Do not shop here if you value honesty and integrity. I was told that they had time to work on my truck. 30 minutes later I showed up and was told they did not have time for me. They said, «sorry. first come, first serve». Have a nice day!

Was not happy at how my car was poorly worked on. My car sat there over a month waiting for them to complete repairs, they couldn’t get the parts. I had to find a vender to ship them my own parts to try and finish my repairs they missed half the list I had gave them to work. Definitely don’t recommend poor customer service!

I’ve used Big John’s for several things over the years. This is my first review. I have a 2014 Ram. I walked into Big John’s with the desire for a 4″ Superlift. Because Dodge puts that on their trucks in the factory and warranties them. Big John’s was pushing BDS. That sort of put me off so I went elsewhere for the Superlift… which was crap! I did more research and found out that most lifts, will not void your warranty. I crawled back to Big John’s feeling dumb. I bought the 4″ BDS. They gutted the old kit and installed the new. 1^st of all Big John’s did an incredible job. 2^nd of all… BDS is the best. Big John’s was right!

There are as many tire shops in Santa Clarita as there are sushi restaurants. I choose Big John’s because of the friendly and honest employees. They don’t push you to replace all four tires if let’s say the rears or fronts still have some life in it. That’s exactly what happened to me. There are so many other tire shops ran by corporations that love to scare their customers to replace all four tires when not required.

Came in for leaking tire. Could of taken me, but fixed tire instead of for a very reasonable amount. Thanks guys!

A year ago when I was attempting to install an interceptor on my Challenger I triggered the check engine light, not knowing anything about cars I freaked out and went to the Valencia Dodge dealership. They were booked but told me they could check it out for $ 200!(WTF). So I went on Unilocal to find an auto shop and found Big Johns Performance right up the street. When I got there it was kind of busy but was immediately greeted by one of the guys at the counter. They did a diagnostic check and determined it to be related to the component I was messing with. I was thinking the price was gonna be at least $ 100 since they were so busy but when I asked so how much do I owe he said don’t worry about it just think of us for your future needs.
2 weeks ago my wife and I purchased our Jeep and wanted to get a lift and maybe tires but didn’t know anything about Jeeps or parts but remembered that Big Johns took care of me so I called Big Johns and spoke with Daniel «Dan» and he was extremely helpful, knowledgeable, friendly, and funny he wasn’t pushy or trying to sell me on what he thought was best just listened to what I wanted and gave suggestions off of that and when I would go against his suggestions he didn’t make me feel like I was wrong and he was right. Fast forward 3 weeks later my wife and I had Big Johns do an entire makeover on the Jeep with custom powder coating and so much more. Dan, Steve, and the rest of the guys took great care of us from begging to end. The entire experience was stress free and Daniel was always willing to answer all my questions and would explain everything in detail. Dan made this experience as easy as possible and made sure I had exactly what I wanted and Steve did a great job putting it all together.
No matter if it’s a Check Engine light or a complete transformation Big Johns will take care of you and your vehicle. Thanks guys!

Best performance shop in Santa Clarita with outstanding customer service. My tire needed a quick patch up and Big Johns took care of it right away. This is the place to check out if you need any wheel, tire or performance questions and service.

Absolutely! The best place to bring your car for service. Talk about customer service.

This review is two months late but I promised i’d leave the review and am following through with that. I called and spoke to Daniel about getting some J.W. Speaker headlight and fog lights installed in my JK Wrangler and he was extremely helpful. The issue was that it was my only day off and he was backed up with jobs for the day so he wasn’t sure if he could get me in. It wasn’t the end of the world, I just work a lot of hours and wasn’t sure when i’d be able to set it up. Daniel understood and told me if I dropped my Jeep off that day he’d try to get to it but there were no guarantees. He told me he legitimately would try to make it work and any cancellation of appointments or any job that finished sooner than expected and he would get right on it. I figured it was worth it so I dropped off my Jeep around Noon and at about 4pm I get a call from Daniel that the job was done and to come pick up my Jeep.
I was definitely appreciative and will be back when I add my Lift, Wheels and tires! I actually work in the auto business and have referred a LOT of people to Big John’s over the years just based on what I’ve heard from other people and customers. This was the first time I’ve used them personally and they did an exceptional job. I was very happy with the service and the install and will be coming back and continuing to refer people to them in the future.

The Lift Gate Struts broke on my 2002 Yukon several months ago and I couldn’t take it anymore (think grocery time), so I took it here this morning for the repair. Dan handled my order and Steve did the job. Here’s how it went: Began my order at 8am, sat down in their plush leather sofa near the gigantic screen tv, watched some news, got thirsty, walked over to the desk to ask for my keys to get some water, (because I thought nothing had happened to my truck yet), and Dan says, «ITS FINISHED!» I was STUNNED, to say the least. And the cost was reasonable (a buck fifty). Other places TAKE FOREVER to do work to it but NOT HERE. I highly recommend this place. The only negative thing is the business’ parking lot seems to always be full which gives the impression they cannot take any new business but apparently that isn’t all ALL the case. I’ll be bringing my baby (truck) here again.

ABSOLUTELY DO NOT do business with this company! I had a lift kit done by them on my new Chevy truck. It continued to rub after the installation. They kept cutting away at my truck but it continued. About a month after the installation, the rear end bolts that hold the leaf springs on the rear end came loose and so did the rear end while I was exiting the freeway at 60 MPH. I slid for about 2 – 300 yards. So to say the least, it scared me and my family to death. THE REAR END CAME DISCONNECTED on the freeway! I had it towed to them and they put it back together. They also informed me that this happened to another customer of theirs and they fired the technician and «apologized». About a couple weeks later the engine started to leak oil as a result so I took it to the dealer. The representative at the dealer called me and said I need to get there ASAP because BIG JOHNS PERFORMANCE cut my frame when they did the lift and my warranty was void on my brand new truck. The Cv boots are torn also. The manager at the dealership told me that the work they did was dangerous as well. I had their tech come out while it was at the dealer and he refused to do anything about it. I have reported them to the Bureau of Automotive Repair. They did an investigation so I have a report showing their negligence. I have had to contact my attorney to file a Civil Lawsuit against them for negligence, personal injury, and property damage in an amount to exceed $ 150,000. These people could have killed me do to their negligence and will not do anything about it. My attorney is also going to seek criminal charges as well. DO NOT USE THIS COMPANY!

Got a flat tire and expected to wait some time for repair. These guys were on top of it! Less than 20mins to wait and they patched it up for $ 15!!! Killed it! Thanks for taking care of me !

This place is awesome! I had been to two tire shops before I found Big Johns and both tried to bullshit me. Big johns was honest gave me a Great deal on a set of tires and got me in and out under an hour on a Friday afternoon. I wouldn’t go anywhere else in Santa Clarita.

There was a leak coming from the timing chain cover. The dealership quoted a mega price. Big John quoted half the price.
The shop has the policy of first come first serve, and we had to wait a couple of days to get the car in. Once in, it was about 5 hours.
We were very pleased, with the results. Not a drop of oil was found in the garage the next day.

Horrible customer service, hard to get one of them to help you unless you have a personal relationship with them. Constantly have to take my car back right after they had it; damaged amp after service with them was the last straw. Will never go back.

–MONDAY EVENING–
ME: Hey Big John, I need to drop my car off on Tuesday morning, have it back by Thursday mid-​afternoon. The brakes need looked at since the pedal is hitting the floor. It’s also running rough, I believe the timing needs adjusted. I cannot get to it, can you do this?
BIG JOHN: Absolutely, we’ll take a look first thing Tuesday.
I drop the car off on Monday night.
–TUESDAY–
After no word all day Tuesday, I drive past after work and see the car sitting exactly where I left it.
–WEDNESDAY MORNING–
ME: Hey Big John, have you looked at the car?
BIG JOHN: No, sorry. We got busy. We’ll get on it this afternoon.
After no word Wednesday evening, I drive past and see the car sitting exactly where I left it.
–THURSDAY MORNING–
ME: Hey Big, have you looked at the car?
BIG JOHN: No, sorry. We got busy. We’ll get on it this afternoon.
After no word by noon, I drive past to see the car sitting exactly where I left it. I go in.
ME: Are you going to get to the car? Otherwise, I’ll try to get to it myself.
BIG JOHN: Sorry, we got busy. We’ll get on it now.
I go to lunch, come back, and there’s the car on the rack. No one near it. I stay all afternoon, observing, since I had the day off work to start my vacation in which I was towing the car to a show in Vegas. After several 5 minute spells of working on the car over 3 hours, and pouring brake fluid into the master cylinder and pumping the pedal, they take it down.
BIG JOHN: It’s good, man. Brakes are good, and it’s running good. That’ll be $ 80 for the brake bleed.
ME: Thanks Big John.
Mind you, I know they did practically nothing, but I was hopeful, nevertheless.
Fire the car up, idles okay. Brakes are soft. Hit the road to the sound of backfires because they didn’t even attempt to adjust the timing.
The car ran so poor it wasn’t worth taking to the show, so I lost out on another $ 80 for the trailer rental and $ 30 for the show registration. Basically I paid almost $ 200 to have Big John’s hold my car and do nothing to it for three days.
Unfortunate that a supposedly reputable shop couldn’t handle a one hour job over the course of three days. I’d spent probably $ 3,000 at Big John’s in the previous year since going there, and thought they had done an okay job in the past.
Definitely will never take my business there again and no one will ever have my endorsement for these guys.

I had my 2014 jeep tricked out by big johns.
Daniel, josh and little john treated me like gold. A first rate shop with lots of knowledge. If you have a jeep or truck, bring it by for a new look. Round 2 is on order. Thanks guys .
Daniel hooked me up so my rig is sic and everywhere I go people say it’s totally dope .
Thanks again.
