They will not honor their contract with you
They do not intend to honor their contracts and will not pay for authorized repairs without a fight. If you have problems with them, call the PA AG's Bureau of Consumer Protection. My first claim was for a stretched Timing Chain. It took Delta over 3 weeks to make a decision and they ultimately denied my claim using specs from a different engine model (not the engine I had in my car) to justify their denial. Luckily the shop I used was willing to work with me and they provided the specs for my engine, which proved the need for the timing chain replacement. I opened a claim with the BBB and PA AG's Bureau of Consumer Protection. In addition, I sent Delta a letter informing them I intended to file for mediation, per our contract. It still took them about 6 months to reimburse me and when they did, it was only a partial reimbursement. How many people can leave their car in the shop for three weeks while they wait for a repair authorization? The second repair was for bad motor mounts. We tried to get this added to the timing chain repair above but after reporting this to Delta's customer service reps (twice, while the vehicle was still in the shop), they ignored it and accused us of not requesting an inspection to verify this, so we took the car back to the shop. It took Delta over 2 weeks to authorize this repair, which they did after we told them we had filed another complaint with the PA AG's Office. Delta did not authorize enough money to pay for factory parts so we agreed to cover the additional cost so we could get the car back ASAP. About a month after we picked up the car, the auto shop called and said Delta failed to pay their portion of the repair bill; this is the portion they authorized paying prior to having the shop complete the repairs! In the beginning, I had to call almost daily because Delta would change the rules and requirements, sometimes asking for information I had already sent them. Based on my last experience with them, I kept a call log. We have 72 phone calls dedicated to this one repair! In the end, it was the BBB, PA AG's Bureau of Consumer Protection and the letter I sent them informing them I intended to send this matter to mediation to finally get them to send a check to pay the portion of the repair they agreed to in the beginning. As for rental cars, Delta will not authorize a car until they accept your claim and they will only authorize the rental car for the estimated time it takes your mechanic to repair the car. So if the repair can be completed in less than 8 hours, no car for you and no rental car for the protracted amount of time it takes Delta to approve of your claim. The rental car reimbursement is a scam and so is this company. I did get my money out of them (just barely) but it took an excessive amount of work to get them to honor the terms of their contract.
