  In January 2024 I replaced my engine in my 2004 Yukon XL with a Jasper Rebuilt engine. Reference ********. My case number with Jasper is ******. That engine failed within 7 months, with a second engine sent under warranty. The second replacement engine failed within 6 month. After much negotiations since the total time of both engines were 13 months, which exceeded the one year warranty, which starts from the first engine replacement, Jasper sent a third engine at no charge, however, no credit for labor or additional warranty for the third engine. I agreed to this agreement. Almost immediately The third engine has a misfire in 2 cylinders once the speed exceeds 72 miles per hour or 2500 rpm’s.
  
  I believe Jasper deliberately sent an engine that wasn’t tested and recognized there would be no warranty. I don’t believe Jasper should be allowed to sell remanufactured engines based on the number of complaints I now see in the various reviews. Not one of their remanufactured engines operated past 25,000.

  Aside from being various statements being factually incorrect. Such as purchase date which was 1/11/2022, the warranty being 1 year, it's 3 year. The customer or a repair facility has not reached out with any issues on the current unit. 

  A misfire above 2500 rpm could be a number of things and we would gladly assist in diagnosing and if related to the Jasper product offer some possible resolutions. Please have your preferred repair facility reach out.

  In my haste I did not proofread properly.  The origin Jasper engine was installed 1/28/22.  Yukon mileage was 415,480    The engine and kit was listed on the invoice at $4302.

  starting 2/21/24 with the check engine light coming on and off the automobile was brought back.  The odometer reading was 460,662. Miles driven 45,182.  It was determined that the engine could not be repaired and had to be replaced.  A replacement engine was installed April 24, 2024. (28 months after the first replacement engine.).  
  

  By 2/15/25 the second engine started to fail. 37 months after the first replacement. The second engine failed after 18,765 miles.  After discussions with Jasper a third engine was installed at odometer 479,427.  Jasper only warrants 3 years or 100,000 miles so I signed a waiver that indicated Jasper would send a third engine with no warranty.  Unfortunately the third engines check engine light started blinking at 481,000 miles, less than 3000 miles after installing, and only 3 months use age, Engine #3 codes indicates 2 cylinders are misfiring.   The authorize Jasper service station after extensive review feels this engine has internal issues that new spark plugs, wires, etc. cannot fix.

  I am rejecting this response because:

  I have resubmitted the dates of the engines replace and mileage between replacements.  I inadvertently typed 1 year warranty instead of 3 years.   The first engine failed within the warranty period.  The second replacement failed 1 month outside the warranty period attached to the first engine.  The third engine has now failed less than 3 months and 3000 miles after it was replaced.

  I called and spoke with someone on another day and that lady was very pleasant and nice. When I called on 2/10 ***** argued with me about why I wanted a quote and kept repeating the process. She sighed because I got an attitude after repeatedly telling her what I wanted and to find out she couldn't even give me the quote because she's in another dept. the second guy argued with me about it because they talked about it before he got on the phone. He told me she sits behind him, and he proceeded to tell me the process again and then blatantly lied and said you couldn't send in your motor to have it rebuilt. When I asked again, he changed it back to yes Jasper does that. I asked to speak with a manager and ***** got on the phone and was rude. Why is it so hard to simply get a quote on something you asked for? Why did I have to be questioned on why I want to do something the way I want to do it. I shouldn't have to be this frustrated and have to spend my time to file a complaint about their behavior. When I told ***** I would file a complaint he said go for it. I even told him he got on the phone with attitude because he talked to them before he got on and he said go for it.

  In 2021 we had a transmission installed. This transmission is with a business who has partnered with Jasper Engine and transmissions. As we were told they only provide high quality. Well after the first transmission was put in , it was shortly after that we were told by the same shop they would need to replace the already replaced transmission. So with this product we had to have the transmission looked at yet again in 2024 when it was still within the warranty period. The repair facility made repairs in parts attached to the transmission all done when the warranty was still in play. However, we were still charged for the repair ! Now the same issues are happening again and the same repair shop is stating the transmission is bad! After further studying the shifter cable problem can cause premature transmission issues! Between the repair facility and jasper, we feel the current transmission needs to be replaced yet again without costing us additional funds! The repair facility and repair shop are connected as as jasper is advertised on their website and that is all the repair facility uses! We would like jasper to take some ownership in the issues! The only statement they are making is it not within warranty ! However it was within warranty

  

  Business Response

  The shifter cable is not a part provided by Jasper with the purchase of a transmission. If the issue you are experiencing is due to the shifter cable it is not something that would be warrantable. I hope this brings some clarity.

  I am rejecting this response because:
  The issue is not the shifter cable. It is the transmission. It was taken into the shop that jasper has business relationship with in August when it was still under the warranty . The issue was the transmission and it is doing the same thing it is now ! However, the repair facility is now acknowledging that it’s the transmission. The repair facility has tried reaching out to jasper for assistance since they are the ones that have the business relationship with them and jasper has been unwilling to offer any sort of assistance! We had this jasper transmission previously put in and shortly after the transmission had to be replaced again . And then on August it was taken back in for the transmission and the repair shop failed to notify jasper and now the transmission is shot. 
  
  Sincerely,

  Business Response

  JASPER is not offering any assistance as the shift cable(a part not provided by JASPER) caused the transmission issue in August of 2024 and more than likely caused the premature failure of the transmission.  That along with the fact the transmission is 6 months outside of the warranty service period.

  I’m here now at the dealership, after picking my car up yesterday after getting the 3rd new engine put in. This is beyond ridiculous, from 2022 till today my car has been at the dealership, more than it’s been in my own garage. First engine in 2022 compression in cylinder’s was bad, 2nd engine 2023 rear main seal & crack in upper oil pan. 3rd 2024 engine put in and picked up yesterday is leaking oil. I’ve asked Jasper engine to give me a new 3 year 100,000 warranty, since I’m on their 3rd engine from them, and haven’t gotten 15,000 miles out of all 3 of their engines combined. Jasper engine telling me my warranty will still end July 2025 regardless, cause they go by original purchase date, this is totally unacceptable and cheating the customer and they should be held accountable. I’m requesting my money back from original purchase of $5776.00, and that Jasper engine give me a new engine with the full 3 year 100,000 mile warranty for the new engine for my inconvenience and their lack of being able to provide a quality product. Thanks for your help in the matter.

  I'm sorry you have had issues with your Jasper Engine. Both of the warranty issues have been documented under warranty case ******* You are correct a repair/replacement does not extend or alter your warranty. This is laid out in the terms of the warranty and is standard for most product warranties. However, since your concerns are documented for future consideration if there are issues in the future.

  I am rejecting this response because: I’ve never had a chance to enjoy my car, out of the 3 years I never got 15,000 miles out of 3 different engines. Then 3rd engine they put in is still currently in the shop trying to get fixed for an oil leak. The 3 years 100,000 mile warranty will be up July 2025, due to everything that has happened, Jasper engine should give me my money back for the engine and the installation I’ve paid $12,581.36 since they can’t produce a quality product. That’s really the only way to make this right, and I keep the current motor and Jasper engine give me a new 3 year 100,000 mile warranty for my inconvenience…..

  I am rejecting this response because: because a 3rd Jasper remanufactured engine was just put in my car Nov 14 2024, I drove home 40 miles and the engine is leaking oil, Jasper engine wanted to send a 4th engine to the dealership,  the dealership said they’re not putting in another Jasper remanufactured engine, so Jasper engine told the dealership to make every effort to fix/stop the leak. I have zero confidence in Jasper remanufactured engines at this point! It really has me wondering what a judge would have to say about all this at this point. I feel it’s only fair to me to give me my money back for the engine and the installation I’ve paid for $12,58136, since Jasper engine can’t provide a quality engine, and don’t want to warranty a new engine for 3 years 100,000 that was just put in past the original purchase date July 2022 - July 2025, even though the customer hasn’t gotten 15,000 miles after Jasper engine 3 attempts to send a remanufactured engine to the dealership to have installed in my car. So I’m still requesting my money back for engine and installation I’ve paid, plus to keep current engine put in Nov 14 2024 and for Jasper engine to give me a new 3 year 100,000 mile warranty on this engine… Like I previously stated it’s only fair that these request be honored, since I’ve been so inconvenienced by Jasper engine from 2022 to this day, and my car being in the shop from Nov 15 2024 after picking it up Nov 14 2024 and having to take it back the next day and it’s still currently at the dealership, because the 3rd engine provided by Jasper engine is leaking oil, no customer should have to deal with this, especially a retired US Navy, Disabled Veteran who’s hard earned money has been spent! After reading all the negative reviews and complaints, has me wondering how is Jasper engine in business still? This is tragic……

  I had this jasper engine installed in my 2013 jeep wrangler in January of 2020, I have had countless problems since, it came with an engine tick from a lifter within a year of getting it in which they wouldn’t fix, and I believe I filed two complaints with them as well, now it’s been only 4 years and the head gasket has a leak and multiple other parts of their engine has had problems which they refused to cover.

  I bought a crate motor from jasper engines at the end of last year since then I've had to go back and replace that brand new crate engine three different times. The shop has had the truck longer then I've been able to drive it in the past year. I've just lost my job because of not having a truck for work because I'm waiting on another enging.i can't pull a trailer or haul a load and I don't dare put it on the parkway because it breaks down so much.

  In March of 2023 we purchased our 2015 GMC Yukon XL Denali from ******** in *********, KY, there was a tag in the glovebox for a replaced Jasper transmission. That transmission was replaced in 8/2021 at a little over 140k miles. We just picked up our GMC from ***** in **********, IN on May 13 after paying $1.866 for labor and the transmission is already slipping. Going uphill it makes a loud metal-on-metal groaning. This is absolutely unacceptable for a business to be profiting off products with a very high percentage rate of failure.
  
  Jasper transmissions fail. Period. Everyone knows this. But they shouldn't be failing or have failed within 200 miles, nor 30k. This is our main vehicle, practically our only transmission and time is money. We have to take our vehicle back again to have this remedied, lose our vehicle and what, have ANOTHER failed or failing transmission in a fraction of the time that a normal non-Jasper trans fails.

  I purchased a Rebuilt motor from Jasper. Since the day it was installed it has burned oil. The motor was installed at approx 303,000 miles at 308,981 the Dealer “Reagle Dodge “ added 2 quarts of oil, at 309,758 another quart was added, 310,225 another quart was added, 311,286 2 quarts where added and today at approx 313,860 another quarts was added. I have called Jasper on 2 different occasion today 4-6-24 I spoke with the warranty dept. I was told the Industy Standards allow 1 quart of oil every 1000 miles. I cannot believe after paying $8700.00 I was told that. All I ask is the motor be replaced it’s obvious there is an issue with it.

  

  Business Response

  Date: 05/07/2024

  Hello as we explained when you called us yes 1 quart in 1,000 miles is industry standard but your report of 2 quarts in 1,000 miles is excessive and needs to be diagnosed. Oil consumption could be something serious like a piston ring issue or something simple like a restricted Crankcase vent system. Please have the shop contact us to continue diagnosing. 

  Customer Answer

  Date: 05/09/2024

  I spoke with several Jasper Certified Installers, all of them said that the motor should not be burning /using 1 quart of oil every 1000 miles. However mine burns/uses at least 2 quarts of oil every 1000 miles. I would have never purchased a motor thru Jasper had they advertised on their website that the motor may or may not use 1 quart of oil every 1000 miles. That’s ridiculous. So I am to believe that the “industry standard” allows 1 quart of oil to be used every 1000 miles?  I have never heard of such a thing nor have any of the mechanics I spoke with.  I will take my van back to the dealer and have them call Jasper.  As I said , I just want the more replaced / repaired whatever it takes so it doesn’t use /burn oil. I think for the money I paid it’s not to much to ask.

  The transmission on my 2002 Toyota Tundra has been replaced twice, both times with Jasper rebuilt units. The first time was in 2020. That unit failed after 750 miles and was replaced under warranty, however I incurred a unreimbursed charge of $263.00 due to Jasper refusing to pay the full installation cost.
  This replacement unit recently failed after less than 10,000 miles. Jasper refuses to accept any responsibility for this obviously defective unit.
  Jasper’s utter lack of integrity is beyond comprehension.

  

  Business Response

  Date: 04/25/2024

  In order to look into this for you further I will need a production number. However, if the purchase was in fact made in 2020 the purchase would no longer be under warranty. The longest warranty that we offer is 3 years, or 100,000 miles, whichever occurs first.

  I am rejecting this response because:

  The second replacement unit started malfunctioning in January of 2023 six months prior to the expiration of the warranty. 
  Furthermore, if Jasper had any integrity they wouldn’t be hiding behind a technicality to keep from doing the right thing and would instead be making every effort to rectify their obvious failures.

  Thank you. I looked into this a bit for you. We assigned warranty case ****** to this matter. Unfortunately, this unit is one that we no longer produce. The fact that we no longer have the ability to produce these, coupled with the fact that the original purchase date was 5/21/2020 eliminates any option we have to replace this.
