Auto Corral

I had my engine rebuilt there and had a 1 year unlimited written warranty. I tried calling numerous times and left messages on the answering machine and I have had no response from ANYONE! Spent over $2,500 dollars and vehicle has numerous problems within 4,000 miles. Oil leaks, crankshaft and camshaft pulley wobbles, wrong bolts used, used parts instead of new ones. Major problems and no help. Now I have to send a certified letter and take them to small claims court.
