Although a couple of their employees tried to help, the owner jacked us around for two weeks promising to come to us to service our diesel engine but finally rudely told us that he had been telling us for two weeks to have our vehicle towed to his shop (a blatant lie!} and that he had quoted prices (never did). Do not trust them! read more

terrible customer service. The person on the phone Phone had a really high ego and could not answer simple questions on repair repairs. I would not recommend. read more

I had a great experience here thank you I was coming through up from Mexico and had a breakdown....

I had gotten my A/C repaired with them. I was told my vehicle would be done within the same day and I was lied to. I call 4 different time to confirm and at the last time I called 1 hour away from them closing I was given confirmation my the owner that it would be done. 30 mins later I got a call form my driver that explained to me that they are closing and then I was told that they would not complete repair today and that they would do it tomorrow. One of the worst business practices is to lie to customer and keep lying until the end and cause delays for the customer. Prior to bringing in the vehicle to the shop I called the shop in advance to get parts sent over to them to get the repair going as soon as possible and was quoted at 98$ per hour for labor. When it got time to payment time I was told I need to pay 125$ an hour due to me bringing in my own parts from the A Volvo dealership. I was never told before that I would be charged additional to bringing in my own parts to the shop. The shop had all the time to explain this especially when I told them I would be bringing in my own part at the time of the conversation when I was quoted 98$ an hour. this is an extremely high lack of professionalism from this shop. When I confronted the shop about its lack of professionalism they cursed me out on the phone knowing what they did was wrong. surprisingly this is my second encounter with this shop as I had forgot I came here before and had waited an additional day to get my repair done the first time around. I have this shops number saved on my phone as DO NOT GO TO and this speaks volumes form someone who give this shop a second chance to repair and replenish name and still ended up doing more damage then the first time. read more

See all

Stay away from this business. They take advantage of customers passing-by that are in desperate need of repairs. My truck came out worst than it came in. Cannot keep their word on when they can start a job because they have no idea how to even finish it. I brought my own parts because they couldn't supply them, they installed a brand new injector, and charged me $2k for completing half the job. Went to another shop because it was running even worst than before. Had to pay another shop to do the same job i paid Cornwell to do. I paid only $800 for a real mechanic to do the job right (same equipment, only thing that changed was the mechanic). Save your hard earned honest money and stay away from this shop. I recommend everyone with a similar experience to report such incidents to the Better Business Bureau here: https://www.bbb.org/file-a-complaint read more

Cornwell's Truck Repair - Company who is lying! - Transmission Repair Near Me - Tucson, Arizona

Do not use this business. Should have taken other negative reviews into consideration. Traveling with pick up that needed a power fluid flush due to moisture in fluid. This work is 100.00 or less at a reputable shop. The shop was a mess, no working pump to remove fluid, no needed tools or fluids available. Mechanic had to make shift the best he could making a trip to auto parts store and attempting to find, or repair needed tools. Left 2 hours later with moisture still in fluid and a 180.00 bill due in cash. Consider they will not accept a credit card. Just spent time on my driveway attempting to remove power steering fluid from concrete. This was due to the fact this shop sprayed power steering fluid all over engine compartment. The manager was rude with no explanation of the high bill. Called and explained situation to Tuscon location. No explanation offered. read more

worst place you can try your luck , overcharged , broken nuts and bolts on the trailer hub , only police could stop this guys from hurting my driver read more

Worst service I've ever used !!!!!!! Worked on my starter 10 hrs , gave me a huge bill for $1500 just changing the starter ( parts and labor ). At the time of paying , they told me I can pay only $500 CC and the rest of the amount cash. Asked them to split the payment in 3 amounts and use the CC ?! That's when their manager started yelling at me - "don't teach me how to do business " !!! Worst place !!! Avoid them !!! Don't even waste your time and money ! read more

These people deserve no rating because they are a bunch of idiots... Kept me on their yard 15 hours... Replaced a part that they broke trying to convince me it was already broke... And then had an incompetent individual who didn't even have the right tools to work on my equipment... They installed a part that didn't even need to be replaced and not only that, they had to Jerry rig the part to get it to fit... Then they had the audacity at the end of 15 hours to charge me $2,000... Needless to say they didn't get it... They are crooks... They milked the clock, no level of professionalism whatsoever... Stay away from these guys... Worst place ever been to in the years I've been in the business read more

For your money and time , please stay far far far away from this fake truck repair shop，my truck was shinning a red light for the DEF and limited speed to 55 miles , we were so unlucky searched a near shop to go inside this damn place . They waisted us 4 days and 2K to fix nothing . I got my truck even worse when I finally noticed they have no idea on fixing my truck , then I was been robed 2K with thousands of lights on and with limited speed to 5 Miles to get my truck out , They lied day by day to me on the truck repair time and status , and get my computer out to dealer to updated software without my concert , wasting my time and money , just give them another excuse to charge me more , they totally don't know what they are doing on my truck . All they did I know is drain my DEF out and refill it with new DEF , clean the nozzle, that is what they spend 4 days and 2K to do for my truck , then most of time is connecting to a computer and leave it alone waiting time , then when I decide to pull my poor truck out from that damn place . They already messed up my truck system and without any way can fix it , but they still rob me 2K to get my truck out of that hell garage. read more

This place is SHADY THEY charged me $2,400 for the axel guy to fix my spindle when I tried to pay the axel man they blocked it. It didn't dawn on me that something fishy was going on. They actually only charge about $1,400 for the spindle repair Cornwell taxed $1000 for making a phone call there are plenty of shops in the area I will never go back and I travel past there 2 times every other week PLEASE DONT GET SCREWD TAKE YOUR TIME AND FIND A BETTER SHOP THAT CAN HELP YOU AND NOT KICK YOU WHEN YOUR DOWN!!!! read more

These guys are super unprofessional! Scheduled to have them diagnose my truck, no call no show. Had to call several times before I even got a hold of them 2 days later. Scheduled again, no call no show. I got a hold of them and was given a bunch of excuses as to why they couldn't come out. Finally was told they'd be at my place in the morning. AGAIN, no call no show and now can't even get a hold of them. Absolutely unacceptable and no way to do business. They charge an arm and a leg and I was going to pay it-but I will certainly take my business elsewhere and YOU SHOULD TOO read more

very very terrible place, do not send your truck there, they will make it worse. they only want to take advantage from you, not gonna help you with anything read more

I cannot say anything good about These lying, cheating low down scoundrels. They tried to tell me mice ate my wires, they tried to tell me my batteries are bad, they stoled four of my batteries and They tried to tell me they put the driveline back in after the towing company had to take it out to move the motorhome, none of the shit was true. The screwed with my motorhome for one year, and I had to spend the last week just trying to get them to put it back together and clean it up from all the grease inside so that I could move it to a reputable dealer. They broke and destroyed More than they fixed and that's because They didn't fix anything. Eddie's towing the driver saw them Cut a truckers airline when he pulled into the yard, and he had to tow the truck out because Greg the owner and his clowns messed with the truck a long time just like He did my motorhome. If you know anybody that has a truck or motorhome tell him to avoid Cornwells truck repair on Craycroft Road in Tucson at all costs you will be sorry if you go there you will lose money and your motorhome or truck would be damaged. I do not know how these clowns stay in business. Bad bad place. read more

These are are unprofessional, they are running a big "repair trucking center" but they don't accept any credit cards, are a pain in the ASS to try to reason a way to get them paid. On top of that they over charge for repairs, for a simple seal my trailer was missing charge over 400 dollars on services. I mean really, shops in Arizona are prices of shit. Really hate dealing with this type of business in that state. How are you not going to accept debit or credit cards in this line of work. Driver don't driver around holding 1000 dollars cash in hand. STAY AWAY from them as far as possible. read more

We called last minute on a Thursday and asked if they could help us and replace our brakes and he waited for us...not only that he took us to a motel and made sure we had a room. Marc was quite but honest and efficient! Thank you for your help! I definitely recommend them read more

DO NOTuse this shop. I had the high pressure fuel pump and injectors replaced. It took 31days. I could have done it myself in less time. I received a price from the dealership in the middle of this mess. They would have been $1,200.00 cheaper and would have taken 1 week or less. Bid up front. Nothing up front with Cornwell. They can't program my injectors they said they should be able to. Now I'm at the dealership because they have the correct programs . Cornwell was supposed to give me the codes from injectors so if they could not do it , I would have to give to dealership for programing. But they can't do that right , now have to pull valve cover to get the numbers. I should have known it would be wrong. Will need to pay another hr of shop time. Total of two at least. Another $300.00 or so. read more

This place does not deserve any stars. Management treats their customers horrible. This place is definitely Scamwells. They scam people into paying for oer parts that are in truth after market parts or some piece of crap they have laying round their yard. They barely have any mechanics working. I don't know how they keep any business with their horrible customer service. read more

When we called told the person who answered what we needed. Mechanic did not bring anything we asked for plus he had no proper tools. Mechanic had to use our tools. When he said he needed to go get parts, we told him go to NAPA which was still open and only three miles away instead he went back to 30 miles back Tucson and brought used parts. After three trips and waiting 8 hours in 100 degree weather, it was fixed with my husband doing the majority of the work on the truck. It would have only took an hour fix if they would just listened to what we needed. Next time, we will call Uber and get the parts on our own. We should of read the reviews before picking this company. Post from Basilique G. 7/15/18 you were right we were over $1000 as well. read more

My dad went to this location to fix his trailer . They took over a week to return the trailer and they didn't do anything to it. All they did was brake a part. They also told me I was only going pay a certain amount and then overpriced it. If you are a truck driver don't fucken come to this bullshit ass location !! They don't do shit to your trailer, they brake a part and overprice the service. read more

Our rv was supposed to be repaired in San Diego but we had some major issues with that repair ( seals and gaskets were left off both fuel and oil repairs) ( leaving us with fuel and oil leaks !!!!)))....this company and the mechanic Adrian jumped on it ( it took a few days longer than we anticipated but parts were not available, it was a Saturday evening when they took us in)...they fixed us up!!!! Thank you , thank you , thank you!!! Would definitely recommend them to anyone in need of diesel repair read more

We were traveling back home to TX from AZ after moving our dtrs best friend to ASU. Leaving Phoenix, we discovered a large screw in our rental truck's tire. Trying to find service @ 5:30a on Sunday morning isn't easy or is WAY too expensive. Airing up the tire wasn't working as the leak was too great. We called Cornwell's and spoke to the owner, who was very kind on the phone. He told us that the shop could help us and someone would be available when we arrived to assist us-7a. We were told that they couldn't fix the tire, but could replace with our spare. We were driving a F250 with a bed full of luggage!! We were immediately helped. The 2 men who helped us were very kind. The owner also came in during the change and was just as kind. All 3 employees were very friendly, even on a Sunday morning at 7am!! We are SO grateful we found them. They were definitely our angels that day. And, we made it home safely to Houston on our spare. Thank you!!! read more

This place was great!! We broke down on a Saturday night in our motor home heading back out of town. The 2 mechanics working on Sunday both spent half the day working on our camper. It was the fuel pump. They had to run across town to get one and the one they got was dead brand new out of the box so they had to go back across town to get another one. Didn't charge us Sunday labor rates and they were very friendly and helpful! They took a credit card for us and since we didn't have anywhere to go since our motor home was what we were travelling in and staying in, one of the mechanics loaned us his minivan to take back to our hotel. Just super nice guys! Very happy with their service! read more

cash only which is bs. and i called last night the guy was asleep and said they dont do road service, i would stay away from place like that
