I ordered a turbo housing from them and they didn't have it but they had one ordered and machined to my specs in less than a week, and called me periodically and informed me of the status, very personable customer service and I would recommend them to anyone! read more

Going on 3 years waiting on a $5,400 order from Jamie Lent and CPP Diesel. No engine. No refund. No communication. Paid by wire transfer February 2023. All we ever got was " 5/26/26 awaiting shipment." Since then? Silence. Now finding hundreds of others with the same story. Attorney General complaint has already been filed. At this point I don't even want the engine anymore -- I want the money back. If you're thinking about ordering from CPP Diesel, do your homework first. read more

We purchased injectors from them weeks ago and still don't have them.

CPP DIESEL - Auto Customization Near Me - East Millsboro, Pennsylvania

My husband and I have also fallen victim to Jamie Lent of CPP diesel. My husband wired him $6,000 for a transmission, May 2025. Several months Jamie pacified my husband with BS stories that it was an irritable old man building it. Then, one day I looked at yelp and got the truth. My husband called and texted and got no answer. Then, he emailed and was told by a person called Beverly that they were too busy to communicate other than email. Yet still, we never got a viable answer. So a week ago I called him, no answer. Then, I texted him, and suddenly he called back. He seemed like a relatable man, telling me his hardships. Claiming all the reviews were false, and those that sued him, actually lost. I let him know my husband is a disabled veteran that served twenty years in the military. We've worked hard for our money, just as everybody else. He needs his truck to continue to provide for our family. After a nice conversation, I was left with his love and respect of the military and a promise of, I'll check on your transmission tomorrow and get you an answer. Tomorrow came and went and nothing but more disappointment. I've since called and texted and I get no reply. Just as I suspected nothing but a sheep in wolf's clothing that supports his family with his fraudulent business. I'll update this post after we receive legal advice. Until then, I pray more people do not fall victim to this career criminal. Edit, so far I have filed a complaint with the BBB and the PA attorney general and since I wired him money I've also filed with the Federal trade commission. Just Google each and you can file a complaint if your not sure how. Also, I've found a Facebook page called, Diesel Trucks Against CPP Diesel. It was created in 2017 by some of Jamie Lents first victims. I encourage all to join as I'm working on getting legal representation and hopeful to turn it into a class action. I want him shut down. The PA state attorney general hasn't done squat about it yet they can actually shut him down under consumer protection laws they can investigate him and close the business. Please Google PA office of Attorney General to file a complaint it only takes a few minutes to fill out. If you have wired him money now were talking federal trade go to reportfraud.ftc.gov and file a complaint. There's also a petition on change.ord called Investigate CPP Diesel LLC for theft of services and fraud. Here is the link https://www.change.org/p/investigate-cpp-diesel-llc-for-theft-of-services-and-fraud?source_location=search&utm_source=share_petition&utm_medium=copylink&utm_campaign=petition_dashboard&fbclid=IwdGRjcAQTpE5jbGNrBBOkImV4dG4DYWVtAjExAHNydGMGYXBwX2lkDDM1MDY4NTUzMTcyOAABHiiHyEZ3nB6U5Mqo51Fo-6b0zRB5RQ8Vout3TvxgOCj6n5WpH4-25R4LNbIu_aem_d3hpOZdojasqoD1YpdJrpQ read more

This company is absolute trash. Took my money the day I ordered. After 8 days, they had not fulfilled my order or had any communication. I contacted them for a refund, and they said it would be a couple of days to refund. It's now been a week with no refund or response. I'll be contacting the BBB, and reporting fraud on my card. DO NOT ORDER FROM THEM. read more

very disappointed with this owner . he scams way too many people . I ordered a clutch kit and then I had to cancel the order after it stayed pending for weeks . Then I emailed him regarding the order and he charged me instead of refunding me ! then he marked my order as refunded and it's already been a few months and I haven't seen no refund in my account. I have filed a dispute as well as we'll be filing charges with the PA Attorney General and the BBB. read more

I paid in full for an engine 16 months ago. Throughout contacting the owner and the Pennsylvania Attorney General, CPP Diesel still does not even have an engine to rebuild, and they refuse to refund my money. I do not understand how this business is still allowed to operate. read more

I've been waiting for a refund for 3 weeks. I cancelled the order within 2 days when they changed the status of my ball joints to unknown and couldn't give me an eta when I would get the part. PLEASE DO NOT BUY FROM THEM!!! read more

This company is a joke. Worst customer service I've ever dealt with. After waiting months for the part that was back ordered even though it said in stock got an E-mail my order was refunded with no other explanation. Worst part is it wasn't refunded, going on a month trying to get my money back. read more

There are no words to help people understand how bad Jamie Lent and this business is. He will lie unconditionally to get money out of you. He will then continue to lie to drag out the order. I placed a $21,000.00 custom engine order with aftermarket accessories. I was told 14-16 weeks. I am 32 weeks into this order. He has stated, engines are hard to come by. My core was fully rebuild able. When that was no longer an available argument. He the switched to a bearing back order issue. I called the manufacturer and they said they can have them to me in a week. He then changed to the bearing were being produced incorrectly. I contacted the manufacturer again, they stated that was not an issue and that they had not heard of him or his company. STAY AWAY. HE IS A THEIF, he is one of the most despicable and dishonest people I have ever met. read more

I ordered a head gasket kit from CPP diesel 6 February 2025. On the 19 of February 2025 CPP told me it was back ordered, the head gasket kit arrived on 22 April 2025. My truck rebuild was already completed. I asked for a refund back on February 19th which they declined even though I called them numerous times and sent emails requesting the order be canceled before it was even shipped and they never responded. Believe it or not they called me and said they could not refund the $400+ kit. I would not recommend you buy a nut bolt or screw from this Company. They totally suck. read more

All went well until I hung the phone up and went to review my invoice. In big bold letters above the invoice ON SPECIAL ORDERS THERE WILL BE BETWEEN 15 TO 20 DAY WAIT, SHIPPING WILL TAKE BETWEEN 7 TO 14 DAYS. no of this was discussed before hand. So I waited the 20 days on the 13th of nov. 2025 I emailed, the response was ill look into it right away. On the 14th I emailed again, response was we will contact management as well to get a faster response. On the 17th no answer. I emailed and called on the 18th ( today) no answer. From either last emailed was signed by Beverly. I know his wife's name is Erica his is Jamie lent. Im giving them till Friday to either come up with the pump I ordered or refund almost 400.00. The most i can do is send out bad reviews. It looks at this point their are at least 2.6 k people that have not received their order or parts were bad and if you get a refund it will be months down the road. I will be contacting PA. in his area to see if a complaint or if fraud can be brought against him. read more

0 stars and an F rating. Borderline criminal!! I wish as consumers, we had more recourse. After waiting almost five months for the order, they sent the wrong pistons. They refused to take them back claiming they don't refund pistons. Doesn't say that on their website and they are the ones who screwed up the order! Horrible and dishonest company and garbage customer service. Avoid at all costs. Buy your Cummins parts from PDD or Geno's. read more

Ordered $760ish worth of parts back in september...after almost a couple months and nothing but excuses i finally got the order cancelled. It is now December 19th, and they have yet to "figure out" getting my refund to me. Made the mistake of using a debit card for the purchase, and to top it off, that card expired before they got around to refunding me. Emailing back and forth since they won't answer the phone, and nothing but "we're working on it" and excuses. Never been to claims court before but there's a first time for everything. CPP service is ridiculous and they are a scam, don't make the mistake i did and waste your time and money. read more

I would give zero stars if I could. please stay away if you actually want to get a part you pay for. 5 weeks and couldnt even get an answer on when it would ship. they take money out of your account right away though. still no answers on a refund. stay away from this company read more

Our order was placed in May of 2024 for a motor to replace the blown motor of a 2010 F350 Extended Cab Ford. We have yet to receive our product and cannot get any response as to what the order status is to date. They require upfront payment and have yet to deliver the product. Also, they have our motor core that they will not accept nor will they return the motor. If you are thinking about using this group DO NOT ! There are so many other legitimate companies out there; do your research and go with one of them...don't pick this one!! Grade Scale F-- read more

Horrible customer service and inaccurate website. Shows items in stock that are no longer available. Then you can't contact anyone for a refund. DON'T BUY FROM THEIR WEBSITE! THEY PROBABLY DON'T HAVE IT IN STOCK ANYWAY!!!! 1 star is too generous! read more

Do not buy from CPP. This company cheated me out of an expensive part. I ordered 2 and they only sent me 1. They did not return any communication. Disputed with my card company, but in the end, nothing got resolved on my end because they showed tracking and product delivered. But that was for the 1 item. I got taken but will post this to help others to avoid them. Research and look at reviews. CPP is terrible, dishonest company. read more

Worst buying experience I have ever had ordering parts online. No one will answer the phones and responses to email take weeks if at all. I am going on two months and still waiting for a gasket kit. Initially they sent a partial order stating that the entire order was completed. Took me over a month and a bunch of emails to get it straightened out. That's if I ever get my gasket kit which I already received from another company to get my project done. Do not buy from this company!!!!!!!!!!! read more

On November 8, 2024, I hired CPP Diesel to ship my existing Cummins 6.7L Long block to their location, for them to rebuild and ship back to me. After several months, I have reached out to see what the hold up was. I have been getting the runaround and lies. Just for them to write me back finally March 11, 2025 making the excuse that the motor was unusable and that it was burnt between 2 cylinders. Also they claim that they had to source and engine block and head. Since then, I've made every effort to reach out to get a completion date. Requested for it to be sent back and my money returned. They said there is no money back return. How can that be when the service hasn't been rendered? I have filed a complaint with the Pennsylvania States Attorney General, and think all the rest of you should folllow suite. This business is HORRIBLE. Don't do IT! If I could leave a negative star, I Would. read more
