I've been taking all my cars to Jack for many years. He is honest, trustworthy and will NEVER take advantage of anyone. He is the best!!!!

Take my classic cars over anytime they need work. Always quality repairs and a good price.

Jack runs a nice shop clean and honest,,a good guy I recommend him to anyone...and I do all the time...five star shop

If you want your car properly serviced at a reasonable price by an honest mechanic, this is the place. While I typically take my SUV to a local dealer for routine maintenance, lately they have been trying to convince me that I need a multitude of additional services, all with hefty price tags. This is where Jack comes ino my story. He was recommended by a trusted friend who told me Jack would give my vehicle an honest analysis and only do what truly needed to be done at a fraction of the dealer price. Granted, Rancho Cucamonga is not exactly right around the corner, but having piece of mind and more money in my pocket is well worth the trip to me. He has saved my bacon twice in one year and I will definitely be making the journey again. Jack is the best!!! read more

1st of all, the Owner was Rude. 2nd he took a job from from another shop called Tire Choice. He tried to fix the axle problem and idling problem from the 1st shop. He then said, they just told me to get it started. Then, I drove it and problem was still there. I basically had to deal with this shop, instead of Tire Choice and paid $1900 for nothing. They broke my door handle and speedometer. When he said it was gonna take time to find parts. All of a sudden the car was done in 2 weeks and he wanted cash?. I called him about the same problem. I went back and he said " that's the best I can do " . I then called the VW dealer and they referred me to Hans Automotive in Colton. He repaired the the problems and even stated " how did he even tune it without tuning screw?...and broken spark plug?... reported to BBB, department of consumer affairs, the governor Rob Bonta. Time will tell, we are living in a racial world. read more

Bystrom Automotive - Auto Repair Near Me - Rancho Cucamonga, California

I've been going to this mechanic for over 20 years. He's reliable, trustworthy and very honest. If your vehicle doesn't NEED it he won't try to sell it to you. Highly recommend him read more

I have been taking my cars here for 15 years at least. If you're looking for a professional and reasonable mechanic, look no further! I trust Jack will always give me a fair price and do a great job. Here's just one example, I needed a repair so I brought in my Acura to Jack expecting a pricey estimate, instead Jack advised me to have the repair done at the dealership because this particular repair was still covered under my warranty! Jack will fix the problem every time! I had a van with squeaky breaks, it was new so I took it to the dealership numerous times, with no results. I finally took it to Jack, problem solved first try! I will always use Jack and highly recommend him for all your car repairs! read more

If you want your car fixed right this is the place to go. Jack is very trustworthy he will fix your car right the first time, he is dependable and will not oversell you. Being an ex Toyota dealership service manager, I know how mechanics work to make money for repairs; scare tactics, pressure sales etc, Jack is the guy who fixes your car with know frills, you don't get a run around . A work colleague referred him to me when I needed major engine repairs after a Chevy dealer diagnosed it, after talking to him about the repairs, I realized that the dealer low balled me on the repairs to get me to have fix it, Jack told me up front what really needed to be done without calling me to keep adding on. This is a technician who knows your car. If your on the fence to find a place to keep your car running right, Jack Bystrom is the place. I highly recommend him. read more

This guy is ALMOST A THEIF... took my 1989 GMC for repair, they took over a month to fix! Marked up parts and insulted me on how my vehicle was JUNK! When he used parts from a junkyard to repair!! I saw and told him part was on eBay for under 50 dollars!! Insisted only he could get the Correct part...then took most of my gasoline out of a 35 gallon tank!! Charged me $850. This guy is ALMOST A THEIF... BEWARE OF HIM... read more

Thank you for being an honest mechanic... You recently did work on my 2003 Sequoia which had work done on it by Auto & RV did. I thought I had a head gasket leak and you took the time to diagnose the issue which was not a blown head gasket but a thermostat O ring which should have been done correctly by the last shop that did work on my car. Fair price on the work. Thank you again. read more

Buy your own parts. You will get ripped off on parts by at least twice the original cost. Told me the part I needed was about $300. Looked it up myself it was $89 read more

Jack is a real piece of work. I was there 2 weeks ago and he quoted me a price without including labor and the diagnostic, I guess he thought I was just going to buy the part?!! I should have left then but I really needed my car. When he called me to tell me it was ready I nicely asked if I could pick it up the next morning he said nope come get it now! I asked if he would just leave it in the street, a public street, as I was out of town he said nope. My cousin had leave work to pick it up for me, and he was rude to her and made her wait. Never again. read more

Jack is by far the best mechanic I have ever used. He is straight up, no frills and no sugar coating. Some people may not like that but instead what you get is a beyond competent mechanic who is as honest as they come and will always try and save you money. He has worked on all my cars from my 66 British MGB to my 2017 Ford F250 diesel and everything in between. The man knows cars. I highly recommend him, he doesn't use cheap-o Chinese made parts so the cost may be higher but you wont worry about it breaking again 3 months down the line. Of course if you want him to use cheaper parts he will resource them for you. Many times I have brought him my cars that he found were miss diagnosed and ended up saving me thousands. He could have just lied and did the "repairs" but he values the customer and makes his money with repeat business. I have moved to Laguna Beach and I still take my cars to him because I just am not going to find better service. read more

very good place to get your car serviced ive been taking my f150 and honestly i wouldnt go anywhere else. definately give them a shout if you are in the area they are very good at what they do. 10/10 would recommend. read more

I have been going to Jacks for several years. I first took my car to the dealer for repairs and ya that was an arm and a leg quote I told jack what they recommended and he told me what I could wait on and what needed to be done right away and saved me 800.00 dollars I think he is the most honest and reasonable auto repair person. I will always go to Jack and refer anyone to him... read more

Jacks the best, plain and simple. Been the family mechanic for almost 15 years now. Tried taking my car to different places that were sooo expensive and the wait time would be ridiculous, but I take it to jack and it's reasonable, quick, and efficient. He's a down to the point kind of man and I wouldn't trust my car with anyone else. read more

Love this place !!!! He has been working on my cars for 15 years . Greatest mechanic / dr of cars. He is knowledgeable and whatever he fixes it is fixed for life. You will not be disappointed. read more

There are two reviews on this site that I question. Jack has a fairly small shop in Rancho Cucamonga and I highly doubt that a person from San Pedro and Pasadena would take their cars that far for his services. Most of the reviews here are from this local Rancho/Ontario area. The most telling reason I question those two negative posts is that we have done business for more than 20 years with Jack and find him to be honest beyond reproach, skilled and always kind and accommodating. If you read all the other reviews they have had the same experience as we have had. I have referred many people to him and they too have continue to take their vehicle to him. My husband even trusts him with his classic 1957 chevy! We have also found that he will not do expensive work on your vehicle if it can be done for less. I think those contributors were referring to another shop or else they had a completely different experience than anyone I know! read more

I have two cars. Brought one to Jack Bystrom that needed several things done to it including a timing belt. While I was there I thought I'd go ahead and have him do some other work I had been putting off. I asked him to replace one particular item and he told me it wasn't needed. Car has been working great! Honest mechanic. He could have replaced the part ( or not ) and charged me and I wouldn't have known the difference. Thank you Mr. Bystrom for running a repair shop where I can have confidence the job is done right. read more

Great service. Been bringing my cars here for 10 years. Charles doesn't understand that u get what u pay for. They choose quality over cheap parts. read more

Excellent place to get your car worked on. Very honest!!!! That's hard to find now!!! Took my truck to worked on and because I don't drive it much almost a year later the same issue came back. So I took it back and he was so understanding and replaced the part under warranty and didn't charge me anything extra. Where else can you find service like this?? I will take all my cars here for service and recommend to my family and friends. read more

Was recommended to go to Jack. I called, he said bring it down he would help pinpoint the problem. I got there he grabbed a couple tools and got right under my hood and did not charge me a thing, I don't know if this is normal for him or he is just in the Christmas Spirit. Thanks Jack!! I owe you that burrito!! read more
